Answer:
-23
Step-by-step explanation: You have to combine like terms first:
-3.8x -5.9x =223.1
-9.7x = 223.1
Then divide om each side of the equation by -9.7.
-9.7x/-9.7 = 223.1/-9.7
x =- 23
Answer:
x=-23
Step-by-step explanation:
- <u>3.8x </u>- <u>5.9x </u>=223.1
Collect like terms by calculating the sum or difference of their coefficients
(-3.8-5.9)x
calculate the difference
- <u>9.7x </u>=223.1
Divide both sides of the equation by -9.7
-9.7x÷( <u>-9.7 </u>)=223.1÷( <u>-9.7 </u>)
Any expression divided by itself equals 1
x=223.1÷(-9.7)
x=-23

Answer:
40w^3
Step-by-step explanation:
I'm assuming you meant w^3 (w to the third power). In that case, you would just add 34 + 13 + 11 - 18 because they are all like terms (coefficients of w^3).
" the sum " means add
.Answer: C
Step-by-step explanation:
