A teacher asked the class to solve the equation 3(x + 2) = 21. Robert wrote 3x + 6 = 21 as his first step. Which property did he use?
Answer:
He used the distributive property
Answer:
Robert used the distributive property.
Step-by-step explanation:
3(x + 2) = 21 <------- is the original equation.
3x + 6 = 21 <------- is Robert's first step.
Distributive property is a property that states that multiplying the constant by the numerical values/variables in the parentheses will equal the same as multiplying the consonant by the values added together.
Robert multiplied 3 times "x" and "2." This is the distributive property.

Noah makes an açaí bowl using 1/4 cup of bananas for every 1/3 cup of apple juice. He wants to know the number of cups of bananas per cup of apple juice he uses when making the bowl. Which ratio of cups of bananas to cups of apple juice is equivalent to 1/4: 1/3 ?
Answer:
3/4 cup of bananas per cup of apple juice.
Step-by-step explanation
1/4 = 1/3x, then solve for x.
1/4 * 3/1 = x
3/4 = x
Ratio of cups of bananas to cups of apple juice is 3 : 4.
What is Ratio?
A ratio indicates how many times one number contain in another
number.
Given that;
Noah makes an bowl using 1/4 cup of bananas for every 1/3 cup of apple juice.
Now,
Ratio of cups of bananas to cups of apple juice = 1/4 : 1/3
= 1/4 ÷ 1/3
= 1/4 × 3/1
= 3/4
= 3 : 4
Thus, Ratio of cups of bananas to cups of apple juice is 3 : 4.

PROBLEM: (IF YOU TROLL I WILL REPORT) Riley has a rectangular shaped patio that is 13 feet long by 15 feet wide. He wants to DOUBLE THE AREA of the patio by increasing the length and width by the same amount. (200 POINTS)
1. Write an EQUATION that represents the total area of Riley's proposed patio.
2. To the NEAREST TENTH of a foot, what is the LENGTH and WIDTH of the new patio?
THANK YOU!!
Answer:
Part A)
[tex]390=(15+x)(13+x)[/tex]
Part B)
Approximately 18.77 feet long by 20.77 feet wide.
Step-by-step explanation:
Currently, the patio is 13 feet long by 15 feet wide. Therefore, the area right now is:
[tex]A=13(15)=195\text{ feet}^2[/tex]
We will increase the length and width of the patio by the same amount such that the new area is double the previous amount.
Part 1)
The previous area is 195. Therefore, we would like to the new area to be twice of that. Hence, the new area is:
[tex]A=2(195)=390[/tex]
We will increase the length and the width by the same amount. Let’s call this amount x. Then by the area formula (A=bh), we can write:
[tex]390=(15+x)(13+x)[/tex]
390 represents the doubled area. (15+x) is the width after the increase x, and (13+x) is the length after the same x increment.
Part 2)
So, we will solve for x. First, expand:
[tex]390=195+15x+13x+x^2[/tex]
Simplify:
[tex]x^2+28x+195=390[/tex]
Subtract 390 from both sides:
[tex]x^2+28x-195=0[/tex]
This is a quadratic. Hence, we can use the quadratic formula:
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Our a=1, b=28, and c=-195. Hence:
[tex]x=\frac{-28\pm\sqrt{(28)^2-4(1)(-195)}}{2(1)}[/tex]
Evaluate:
[tex]x=\frac{-28\pm\sqrt{1564}}{2}[/tex]
Simplify the square root:
[tex]\sqrt{1564}=\sqrt{4}\cdot\sqrt{391}=2\sqrt{391}[/tex]
Hence:
[tex]x=\frac{-28\pm2\sqrt{391}}{2}\\[/tex]
Simplify:
[tex]x=-14+\sqrt{391} \text{ or } -14-\sqrt{391}[/tex]
Approximate:
[tex]x\approx5.77\text{ or } x\approx-33.77[/tex]
In this case, we can reject the negative solution.
Hence, the value of x is 5.77.
This means that we should increase the our length and width by 5.77.
Hence, the new length will be 13+5.77 or about 18.77.
And our new width will be 15+5.77 or about 20.77.
So, the new dimensions is approximately 18.77 by 20.77

A vehicle travels 57 kilometers north and then travels 26 kilometers south. What is the current position of the vehicle? (2 points) a 26 kilometers south of its starting location. b 83 kilometers from its starting location. c 31 kilometers north of its starting location. d 83 kilometers north of its starting location.
Answer:
C. 31 kilometers north of its starting location
Step-by-step explanation:
Please see attached a rough sketch of the situation for your reference.
Step one:
Displacement North= 57km
Displacement South= 26km
Required
The final displacement
The current position is attained by subtracting 26km from 57km
=57-26= 31km
Therefore the current position is
C. 31 kilometers north of its starting location

A. 32.08
B. 14.42
C. 9.01
D. 20.05
Answer:
A. 32.08
Step-by-step explanation:
The figure given is a right triangle. We would apply trigonometric ratios formula to find x.
Reference angle = 58°
Hypotenuse = x
Adjacent length = 17
Thus, we would apply the following:
[tex] Cos(\theta) = \frac{Adjacent}{Hypotenuse} [/tex]
Plug in the values
[tex] Cos(58) = \frac{17}{x} [/tex]
Multiply both sides by x
[tex] Cos(58) \times x = \frac{17}{x} \times x [/tex]
[tex] Cos(58) \times x = 17 [/tex]
Divide both sides by Cos(58)
[tex] \frac{Cos(58) \times x}{Cos(58)} = \frac{17}{Cos(58)} [/tex]
[tex] x = \frac{17}{Cos(58)} [/tex]
[tex] x = 32.08 [/tex] (2 d.p)
Select the equation that represents the line that passes through (1,7) and is parallel to y = 5x + 4
Answer:
a
Step-by-step explanation:
it has to have to same slope as the first equation so you have y=5x+b then what you do is plug in the points and solve for b. which gives you 2. so your final equation is y=5x+2
7=5+b
-5 -5
2=b
Answer:
The equation that represents the line that passes through (1,7) and is parallel to y = 5x + 4 will be:
[tex]y=5x+2[/tex]Step-by-step explanation:
Given the equation
[tex]y = 5x + 4[/tex]
Here the slope is:
[tex]m=5[/tex]
as comparing with the [tex]y=mx+b[/tex], which is the slop-intercept form where m is the slope and b is the y-intercept.
As we know the point-slope form is
[tex]y-y_1=m\:\left(x-x_1\right)[/tex]
[tex]y-7=5\left(x-1\right)[/tex]
Add 7 to both sides
[tex]y-7+7=5\left(x-1\right)+7[/tex]
[tex]y=5x+2[/tex]
Therefore, the equation that represents the line that passes through (1,7) and is parallel to y = 5x + 4 will be:
[tex]y=5x+2[/tex]if x = -1, then which of the following equations makes a true statement
4x+9=20
-4x-5=-15
-3x+15=18
-5x-15=-22

A store sells ½ pound of beef for $0.70. If you are having a party and need 6 pounds of beef for hamburgers, using the unit rate, how much would i cost? Explain.
Answer:
$8.40
Step-by-step explanation:
A store sells ½ pound of beef for $0.70
We find the unit rate
1/2 pound = $0.70
1 pound =
We cross Multiply
1/2 × x = 1× 0.70
x = 0.70 ÷ 1/2
x = 0.70 × 2/1
x = $1.40
The unit rate for 1 pound of beef is $1.40
If you are having a party and need 6 pounds of beef for hamburgers
Hence, the cost for 6 pounds of beef is:
1 pound = $1.40
6 pounds = y
y = 6 × $1.40
y = $8.40
6 pounds of beef for hamburgers would cost $8.40

7g + 35 = 105
Solve for g:
7g + 35 = 105
7g = 170
g = 10
So, the answer is g = 10
Answer:
g = 10
7g + 35 = 105

Sin(x+y) sin(x-y)=sin²x-sin²y
Answer:
Step-by-step explanation:
sin(x+y) = sin(x)cos(y) + sin(y)cos(x)
sin(x-y) = sin(x)cos(y) - sin(y)cos(x)
Sin(x+y)sin(x-y) = (sin(x)cos(y) + sin(y)cos(x))(sin(x)cos(y) - sin(y)cos(x))
= sin^2(x)cos^2(y) - sin^2(y)cos^2(x)
= sin^2(x)(1-sin^2(y)) - sin^2(y)(1-sin^2(x))
= sin^2(x) - sin^2(x)sin^2(y) - sin^2(y) + sin^2(x)sin^2(y)
= sin^2(x) - sin^2(y)
So L.H.S=R.H.S
