Answer:
x = 14
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define equation</u>
4(x + 4) = 6(x - 2)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 4x + 16 = 6x - 12
- Subtract 4x on both sides: 16 = 2x - 12
- Add 12 on both sides: 28 = 2x
- Divide 2 on both sides: 14 = x
- Rewrite: x = 14
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 4(14 + 4) = 6(14 - 2)
- Add/Subtract: 4(18) = 6(12)
- Multiply: 72 = 72
And we have our final answer!
Answer:
it take 41 minutes to 14 people to paint 14 walls
Step-by-step explanation:
we know that
It takes 41 minutes for 9 people to paint 9 walls.
Divide the number of people by the number of walls
so
it take 41 minutes to one people to paint one wall
therefore
it take 41 minutes to 14 people to paint 14 walls
Answer:
a. Base area, B= 24 square units.
b. Volume, V = 96 cubic units.
Step-by-step explanation:
Given the following data;
Length of sides = 4 units
Width of sides = 6 units
Height = 4 units
a. To find the base area, B;
The base of a rectangular prism is a rectangle.
Area of rectangle, B = length * width
Area of rectangle, B = 4 * 6
Area of rectangle, B = 24 square units.
b. To find the volume;
Volume of rectangular prism = base area * height
Volume= 24 * 4
Volume = 96 cubic units.
Answer:
6.25 cups of sugar
Step-by-step explanation:
Let's make a proportion expression:
2.5/48 = x/120
Let x be the amount of sugar needed to make 120 sugar cookies.
Cross multiply:
120*2.5=48x
48x=300
x=6.25
So, you would need 6 1/4 cups or 6.25 cups of sugar to make 120 sugar cookies.
The answer is .4 because 5 divided by 8 gives you .4 and it is postitive
