Step-by-step explanation:
<u>Step 1: Define</u>
x/2 + 3 = 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 3 on both sides: x/2 = 2
- Multiply 2 on both sides: x = 4
Answer:
3
Step-by-step explanation:
2x + 3 = -x + 12
subtract 3 from both sides
2x = - x + 9
add x to both sides
3x = 9
divide by 3
x = 3
List all the info:
3/8 gallon of white paint
2 7/8 gallon of blue paint
11/4 gallon of red paint
First, let’s answer the first question.
Francis has made _____ gal of paint when he first mixes the three colors.
Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.
Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.
Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)
