Answer:
x=12
Step-by-step explanation:
4x+6y=60 y=2
4x+6(2)=60
4x+12=60
4x=60-12
4x=48
x=
x=12
Answer:
The expression 5(4x - 7) + 3(3x + 3) can be simplified to 29x - 26
Step-by-step explanation:
The first step in solving this is to apply coefficients to the contents of the brackets:
5(4x - 7) + 3(3x + 3)
= 5 × 4x - 5 × 7 + 3 × 3x + 3 × 3
= 20x - 35 + 9x + 9
Now you can group like terms:
20x - 35 + 9x + 9
= 20x + 9x - 35 + 9
= (20 + 9)x - 26
= 29x - 26
And that is the final answer.
Answer:
Step-by-step explanation:
<u>Full surface area of the rectangular prism is:</u>
- S = 2(ab + bc + ac)
- S = 2(6*5 + 6*4 + 5*4) = 148 ft²
<u>Cost of the wallpaper:</u>
- $740 / 148 ft² = $5 per ft²
Work shown above! Greatest common monomial is 12x^2y
3/10 divided by 4/5
You can solve this problem by changing the second fraction and multiplying. 3/10 times 5/4 is 15/40 = 3/8
