Answer:
8^14
Step-by-step explanation:
8^10 * 8^4
We know that a^b * a^c = a^(b+c)
8^(10+4)
8^14
Answer:
I believe the answer is 4.
Step-by-step explanation:
Since y = 8 when x = 4, y is double or 2 times x. So, when x = 2, y is 2 x 2, or 4.
Answer:
18.2
Step-by-step explanation:
A tenth is the first decimal, on the right of your unit. 5 to the sky (round up) 4 to the floor (round down)
Translating that problem into an equation with x as a variable we get 3x + x +10 = 22. Combine like terms to get 4x + 10 = 22. Subtract 10 on both sides to get 4x = 12. Divide by 4 on both sides to get x = 3.
Now to plug in. The first number was represented by 3x. So substituting 3 for the x we get 3(3) = 9. And again for the second number represented by x+10, 3+10 = 13.
Your numbers are 9 and 13. To check just add them together. 13 + 9 is 22, I'll save ya the effort.
