Answer:
<u>Step-by-step explanation:</u>
The power rule is "multiply the exponents".
You must understand that the exponent of both h and g is 1.
Multiply 1 times 9 for both variables.
2x+x+16 = 70 is the equation for their combined ages in 8 years. combine like terms to get 3x+16=70. subtract sixteen from both sides to get 3x=54. divide by three to get x = 18. so feeder is 18, and mary is 36.
Answer:
56
Step-by-step explanation:
So you just need to find 7 + what is equal to 63. To find this we have to do inverse operation, which means the opposite operation. So, we do 63-7 which is equal to 56. Therefore, the solution to the equation, or x is equal to 56 (C).
Hope this helps !!
