Answer:
1.9
Step-by-step explanation:
First step would be to separate r from t
![\frac{d}{r} = t](https://tex.z-dn.net/?f=%20%5Cfrac%7Bd%7D%7Br%7D%20%20%3D%20t)
Then just insert the numbers
![\frac{57}{30} = 1.9](https://tex.z-dn.net/?f=%20%5Cfrac%7B57%7D%7B30%7D%20%20%3D%201.9)
Answer:
To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.
x +7 - 7 = -2 - 7
When you simplify further,
x = -9.

Answer:
c. 134,847
Step-by-step explanation:
82,000 x (1.051)^10 = 82,000 x 1.64447456 = 134,847
I’m guessing you mean like this.
2x+4y+5x+8y.
2x and 5x are like terms because the x’s are alike. If you add 2+5, the answer is 7. So therefore 2x+5x=7x.
4y and 8y are like terms because the y’s are alike. So the answer to 4y+8y would be 12y.
If you need extra help, give me a problem and I will help you solve it.
