Solve the system:
3x+6y=51
y=40-5x
Write down your solution here
Answer:
x=7 y=5
Step-by-step explanation:
3x+6(40-5x)=51
3x+240-30x=51
-27x+240=51
-27x=-189
27x=189
x=7
y=40-5(7)
y=40-35
y=5
Suppose y varies directly with x. Write a direct variation equation to relate x and y if y = 10 when x = 2
Answer:
y=5x and y=40 when x=8
Answer:
y = 5x
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 10 when x = 2
10 = 2k ( divide both sides by 2 )
5 = k
y = 5x ← equation of variation

Find the largest three-digit number that can be written in the form 3^m + 2^n, where m and n are positive integers.
Answer:
985
Step-by-step explanation:
[tex]let\ m=6[/tex]
[tex]3^{6}=729[/tex][tex]999-729=270[/tex]
[tex]2^{8}=256[/tex] and [tex]2^{9}=512[/tex] which would be to big of a number.
[tex]3^{6}+2^{8}=729+256=985[/tex]
Therefore the largest three-digit integer in this system is 985

India has a 12-foot board. How many 18-inch pieces can she cut from the board?
Answer:
Step-by-step explanation:
There are 12 inches in a foot
So for one full foot in inches you have just 1 foot with 6 inches remaining/ 1 foot with half a foot remaining.
Hope this helped!
Answer: 8 pieces.
Step-by-step explanation;
There is 12 inch in a foot, so they are 144 inches in 12 foot. If India cuts 18-inch pieces, she can cut 8 pieces. You can find this amount by dividing 144 inches into 18 inches, this will be eight pieces.
The temperature outside is currently 10°F. It will fall at a constant rate of 3°F per hour. Which temperature will it be in 4 hours?
A
22°F
B
7°F
С
-2°F
D
-12°F
Answer:
The temperature in 4 hours = -2 °F
Thus, option (D) is true.
Step-by-step explanation:
We know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the rate of change or slope and b is the y-intercept
Let 'y' be the temperature Let 'x' be the time of the temperature in the hour
Given that the current temperature outside = 10°F.
Thus, the y-intercept = b = 10°F
Given that as the day went on, It will fall at a constant rate of 3°F per hour.
Thus, the slope or rate of change = -3°F
(The rate of change or slope is -3 because the temperature is reducing)
Thus, the rate of change = slope = m = -3
Thus, substituting m = -3 and b = 10 in the equation
[tex]y = mx+b[/tex]
[tex]y = -3x + 10[/tex]
Now, substituting x = 4 to determine the temperature after 4 hours.
y = -3(4) + 10
y = -12 + 12
y = -2 °F
Therefore, the temperature in 4 hours = -2 °F
Thus, option (D) is true.

Top triangle:
The hash marks indicate congruence. So, x is congruent to 15 or x= 15
x+6= 21
The length of the sides of this triangle are 15,15, and 21.
Two sides are congruent so isosceles.
Bottom triangle:
The sum of the angles in a triangle is 180.
30+35+x=180
75+x=180
x=105
105> 90, so this is an obtuse triangle.

What is Two-thirds divided by StartFraction 4 Over 5 EndFraction?
A fraction bar labeled 1. Under the 1 are 5 boxes labeled one-fifth. Under the 5 boxes are 3 boxes containing one-third. Under the 3 boxes are 15 boxes labeled StartFraction 1 Over 15 EndFraction.
Answer:
[tex]\dfrac{5}{6}[/tex]
Step-by-step explanation:
The problem says Two-thirds divided by StartFraction 4 Over 5 EndFraction.
Two thirds means = 2/3
It means,
[tex]x=\dfrac{2}{3}\ \text{divided by}\ \dfrac{4}{5}[/tex]
or
[tex]x=\dfrac{\dfrac{2}{3}}{\dfrac{4}{5}}\\\\=\dfrac{2}{3}\times \dfrac{5}{4}\\\\=\dfrac{5}{6}[/tex]
Hence, the required answer is [tex]\dfrac{5}{6}[/tex].

Zach filled 581 one-liter bottles with apple cider. He distributed the bottles to 4 stores. Each store received the same number of bottles. How many liter bottles did each of the stores receive? Were there any bottles left over?
a. 145 liter bottles (There were 2 bottles remaining)
b. 142 liter bottles (There were 2 bottles remaining)
c. 145 liter bottles (There was 1 bottle remaining)
Answer:
a. 145 liter bottles (There were 2 bottles remaining)
Step-by-step explanation:
From this question, the total number of bottles that Zach had to fill with apple cider is 581.
He has to distribute these bottles to 4 stores after filling
The question says each store received same number of bottles.
To get the number of bottles received by each store, we divide 581 by 4
= 581 / 4
= 145.25
Therefore each store gets 145 bottles each and there would be a remainder of 2 bottles

Step-by-step explanation:
In 2006, 65.2 million people subscribed to cable television. In 2013, that number had decreased to 54.2 million. Find the percent decrease in the number of cable TV subscribers from 2006 to 2013. Round to the nearest tenth of a percent.
Given :
In 2006, 65.2 million people subscribed to cable television.
In 2013, that number had decreased to 54.2 million.
To Find :
The percent decrease in the number of cable TV subscribers from 2006 to 2013.
Solution :
Decrease in the number of cable TV subscribers from 2006 to 2013 is :
[tex]Percetage\ Decrease = \dfrac{Decrease\ in \ price}{Initial\ price}\times 100\\\\Percetage\ Decrease = \dfrac{65.2-54.2}{65.2}\times 100\\\\Percetage\ Decrease = 16.87[/tex]
Therefore, percentage decrease is 16.87 %.

Scenario: Does the age at which babies learn to crawl depend on the time of the year that the babies were born? Data were collected from parents who brought their babies into the University of Denver’s Infant Study Center to participate in one of a number of experiments between 1988 and 1991. Parents reported the birth month and the age in which their child first began to crawl. The resulting data were grouped by month of birth: January, May, and September.
The age for when babies learn to crawl is different for Januar,May, and September.. so I guess yes?

the value of x[tex] \text{Given \: Equation : \: 3(x - 2) + 4 = x - 5}[/tex]
You must distribute first ! In this equation , you have the distributive property on left hand side of the equation. You must first get rid of the parentheses.
⇢ [tex] \text{3 × \: x - 3× 2 + 4 = x - 5} [/tex]
⇢ [tex] \text{3x - 6 + 4 = x - 5}[/tex]
On the left hand side , you have two numbers : - 6 and 4. Remember that ' The negative and positive numbers are subtracted but posses the sign of the bigger number. '
⇢[tex] \sf{3x - 2 = x - 5}[/tex]
Move x to left hand side and change it's sign.
Similarly , move 2 to right hand side and change it's sign.
⇢[tex] \sf{3x - x = - 5 + 2}[/tex]
On the left hand side , you have like terms. Combine the like terms : 3x - x = 2x
⇢[tex] \sf{2x = - 5 + 2}[/tex]
On the right hand side , - 5 + 2 = -3
⇢[tex] \sf{2x = - 3}[/tex]
Divide both sides by 2
⇢[tex] \sf{ \frac{2x}{2} = - \frac{3}{2} }[/tex]
⇢[tex] \boxed{\sf{x = - \frac{3}{2} }}[/tex]
-----------------------------------------------------------------
✏ CHECK :
[tex] \text{3(x - 2) + 4 = x - 5}[/tex]
Substitute [tex] \sf{ - \frac{3}{2}} [/tex] for x into the original equation. And simplify !
⇾ [tex] \sf{3( - \frac{3}{2} - 2) + 4 = - \frac{3}{2} - 5}[/tex]
⇾[tex] \sf{3( \frac{ - 3 - 2 \times 2}{2} ) + 4 = \frac{ - 3 - 5 \times 2}{2}} [/tex]
⇾[tex] \sf{3( \frac{ - 3 - 4}{2} ) + 4 = \frac{ - 3 - 10}{2}} [/tex]
⇾[tex] \sf{3( \frac{ - 7}{2} ) + 4 = \frac{ - 13}{2}} [/tex]
⇾[tex] \sf{ \frac{ - 21}{2} + 4 = \frac{ - 13}{2}} [/tex]
⇾[tex] \sf{ \frac{ - 21 + 4 \times 2}{2} = \frac{ - 13}{2}} [/tex]
⇾[tex] \sf{ \frac{ - 21 + 8}{2} = \frac{ - 13}{2}} [/tex]
⇾[tex] \sf{ \frac{ - 13}{2} = \frac{ - 13}{2}} [/tex]
Since both sides are equal , x = [tex] \boxed{ - \sf{ \frac{ 3}{2} }}[/tex] is the correct answer.

Find the exponential function of the 2 points (3, 7) and (5, 63). Use
the formula f(x) = a(b)”.
Answer:
We obtained the two exponential functions:
[tex]y\:=\:\frac{7}{27}\left(3\right)^x[/tex][tex]y\:=-\:\frac{7}{27}\left(-3\right)^x[/tex]Step-by-step explanation:
As we know that the exponential function is of the form
f(x) = abˣ
Given the points
(3, 7)(5, 63)We know these points belong to the exponential function.
so substituting the values (3, 7) and (5, 63) in the function
putting (3, 7)
y = abˣ
7 = ab³
also putting (5, 63)
y = abˣ
63 = ab⁵
Considering the 2nd equation
63 = ab⁵
as
[tex]a^b\times \:a^c=a^{b+c}[/tex]
so
63 = ab³×b²
substituting 7 = ab³ in 63 = ab³×b²
63 = 7 × b²
b² = 63/7
b² = 9
b = ± 3
If b = 3
plug in b = 3 in the equation 7 = ab³ to find the value 'a'
7 = ab³
7 = a(3)³
7 = a × 27
a = 7/27
so, a = 7/27 and b = 3 would give us the function
y = abˣ
[tex]y\:=\:\frac{7}{27}\left(3\right)^x[/tex]
if b = -3
plug in b = -3 in the equation 7 = ab³ to find the value 'a'
[tex]\:7\:=\:a\left(-3\right)^3[/tex]
[tex]a\left(-27\right)=7[/tex]
[tex]a=-\frac{7}{27}[/tex]
so, a = -7/27 and b = -3 would give us the function
y = abˣ
[tex]y\:=-\:\frac{7}{27}\left(-3\right)^x[/tex]
Thus, we obtained the two exponential functions:
[tex]y\:=\:\frac{7}{27}\left(3\right)^x[/tex][tex]y\:=-\:\frac{7}{27}\left(-3\right)^x[/tex]Which of the following most likely causes the rate of a chemical reaction to increase? (5 points)
