Answer:
x=4
Step-by-step explanation:
5(2x-3)-(x+8)=13
10x-15-x-8=13
9x-23=13
9x=36
x=4
They add up to 180 degrees.
5x+7+15x-7=180
20x=180
x=9
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.
