For her birthday party, Tausha is preparing bags of treats to share with her friends. She has 18 candy bars and 12 packs of gum. Tausha wants to use all of her candy and gum. What is the greatest number of bags of treats that Tausha can make if each of the bags has the same number of candy bars and packs of gum in it? How many candy bars and how many packs of gum will be in each bag?
Answer:
Tausha can make maximum 6 bags that has the same number of candy bars and packs of gum in it.
Number of candy bars in each bag [tex]=3[/tex]
Number of packs of gum in each bag [tex]=2[/tex]
Step-by-step explanation:
Given:
Number of candy bars = 18
Number of packs of gum = 12
To find: the greatest number of bags of treats that Tausha can make if each of the bags has the same number of candy bars and packs of gum in it
and number of candy bars and packs of gum in each bag
Solution:
Take H.C.F of 18 and 12
[tex]18=2(3^2)\\12=2^2(3)[/tex]
So,
H.C.F of 18 and 12 is 2(3) = 6
Therefore,
Tausha can make maximum 6 bags that has the same number of candy bars and packs of gum in it.
Number of candy bars in each bag = [tex]\frac{18}{6}=3[/tex]
Number of packs of gum in each bag = [tex]\frac{12}{6}=2[/tex]

Answer:
5:2
Step-by-step explanation:
The answer is 5:2 because:
1) Since there are 2 male teachers for every 5 female teachers, the ratio has to be 5:2 because they did not give us any specific numbers.
For example, if they 10 female teachers, then there would be 4 male teachers. The ratio for this example would be 10:4

The water depth in a lake decreases at a rate of 2 inches per day because of evaporation. How much does the water depth change in 8 days? In 15 days? In 8 days, the water depth changes by inches. In 15 days, the water depth changes by inches.
Answer: In 8 days it will decrease by 16 inches and in 15 days the water depth changes by 30 inches.
Step-by-step explanation:
The water depth decreases at a rate of 2 inches per day so in this case if were to write it as an expression it will be -2x where x is the number of days.
We will have to set it equal the total amount that it has decreased which will be y.
y= -2x If x represent the number of days we will put in the days and solve for y.
y = -2(8)
y = -16 This means that in 8 days it will decrease by 16 inches.
y = -2(15)
y= -30 This also means that in 15 days the water depth changes by 30 inches.
2/3 divided by 4/5 qwertyuioppasdfghjklzxcvbnm
Answer:
5/6
Step-by-step explanation:
The solution of the given fraction is 5/6.
Given that:
Fraction: divided 2/3 by 4/5
To calculate the division of fractions, simply need to multiply the first fraction by the reciprocal of the second fraction.
[tex]\dfrac{2/3}{4/5} =\dfrac{2}{3} \times \dfrac{5}{4}\\\dfrac{2/3}{4/5} =\dfrac{(2 \times5)}{(3 \times4) }\\\dfrac{2/3}{4/5} =10 / 12[/tex]
To simplify the fraction, you can divide both the numerator and the denominator by their greatest common divisor, which is 2:
10 / 12 = 5 / 6
So, 2/3 divided by 4/5 is equal to 5/6.
Hence, the required result is 5/6.

can someone pls help i have been stuck on this one for a little while ):
Answer:
This is not correct
Step-by-step explanation:
on the right side is 3.2 (x-5) this means that it represents 3.2 * (x-5). You have to multiply (according to the distributive property) 3.2 by x and 3.2 by (-5), so you get 3.2x + (3.2*-5) = 3.2x -16
The left side says 3.2x-5, that is clearly not equal to 3.2x-16.
It is impossible to say that there are infinitely many solutions as there are actually no possible solutions. Set the functions equal so it is:
3.2x-5 = 3.2x-16
solve for x by subtracting the 3.2x from the right side and the left side, then add 5 to both sides to isolate the variable with the other terms.
You get 0=11
That is not true.

what is 24/30 written as a decimal
Answer:0.8
Step-by-step explanation:To write 24/30 as a decimal you have to divide numerator by the denominator of the fraction. We divide now 24 by 30 what we write down as 24/30
Answer:
First off, we'll interpret the fraction bar to mean "divided by." This means that 24/30 is the same as 24 divided by 30. Second, you have requested to see 3 decimal places in your answer, so we'll write the 24 as 24.000 instead (a 24 with 3 zeros after the decimal point

What is an equation of the line that passes through the point (2,-2) and is parallel
to the line 5x – 2y = 4?
Answer:
y=2.5x-7
Step-by-step explanation:
First, 5x - 2y = 4
=> - 2y = 4 - 5x
y = 2.5x -2
Since the line we want to know is parallel to the given one,
its slopw would be 2.5 as well
so let the line passes through the point (2,-2) be y=2.5x+a
then 2.5* 2 +a = -2 => a = -7
Final answer: y=2.5x-7
y=5/2x-7 is equation of the line that passes through the point (2,-2) and is parallel to the line 5x – 2y = 4.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that, a line is passing through (2,-2) and is parallel to line 5x – 2y = 4.
We need to find the equation of other line.
We need to write the equation of line in slope intercept form.
5x – 2y = 4
-2y=4-5x
2y=5x-4
y=5/2x-2
The slope of line is 5/2
Since the line we want to know is parallel to the given one,
If two lines are parallel then slope of two lines will be parallel.
So the slope of line passing through (2, -2) should be 5/2.
let the line passes through the point (2,-2) be y=5/2x+c
then 5/2(2) +c = -2
c=-2-5
c=-7
Equation of line parallel to 5x-2y=4 is y=5/2x-7
Hence y=5/2x-7 is equation of the line that passes through the point (2,-2) and is parallel to the line 5x – 2y = 4.

Suppose J is between H and K. Use the Segment Addition Postulate to solve for x. Then find the length of each segment. If HJ=x+10 JK=9x KH=14x−58 a) Draw a sketch of the segments described above b) Write an equaation using the segment addition postulate that will help you solve the problem ___+ ___= c) combine like terms ( x terms on one side of the equal sign and numbers in the other side of the equal sign) ____ = ____ d) x= __ HJ= __ JK= __ HK= __
Answer:
x= 17
HJ= 27
JK= 153
HK= 180
Step-by-step explanation:
If HJ=x+10
JK=9x
KH=14x−58
a) The diagram of sketch of the segments described above is attached to this answer.
b) KH = HJ + JK
14x - 58 = (x + 10) + 9x
14x - 58 = x + 10 + 9x
c)
14x - 58 = x + 10 + 9x
14x - 58 = 10x + 10
Collect like terms
14x - 10x = 10 + 58
4x = 68
Divide both sides by 4
4x/4 = 68/4
x = 17
d)
x= 17
HJ= x + 10
= 17 + 10
= 27
Hence, HJ = 27
JK= 9x
= 9 × 17
= 153
Hence, JK = 153
HK=14x −58
HK = 14 × 17 - 58
= 238 - 58
= 180
Hence, HK = 180
Aliyah's Bikes rents bikes for $10 plus $5 per hour. Shayna paid $45 to rent a bike. For how many hours did she rent the book?
Answer:
7 hours.
Step-by-step explanation:
To solve this problem, you have to make an equation. The equation is 45=5x+10. We have to solve for x. So you put like terms on one side, which gives you 35=5x. We divide by five on each side which gives us x=7.

_________________________________
The sum of the angles of each n-sided figure is found in the following equation :
[tex](n - 2) \times 180 [/tex]
The question's figure is 5-sindes figure
so the sum the angles equal :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
So we have :
[tex]90 + 107 + 144 + 138 + x = 54 0 \\ [/tex]
[tex]479 + x = 540[/tex]
Subtract the sides of the equation minus 479
[tex]x = 540 - 479[/tex]
[tex]x = 61[/tex]
And we're done.

What is the equation of a line that passes through the point (9, −3) and is parallel to the line whose equation is 2x−3y=6?
Enter your answer in the box
Answer:
y = 2/3x - 9
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
m - slope
b - y-intercept
Step 1: Define
Point (9, - 3)
2x - 3y = -6
Step 2: Rewrite given equation
-3y = -2x - 6
y = 2/3x + 2
So our m = 2/3 (Parallel lines have the same slope but different y-intercepts)
Step 3: Find y-int of parallel line
y = 2/3x + b
-3 = 2/3(9) + b
-3 = 6 + b
b = -9
Step 4: Write parallel line equation
y = 2/3x - 9
