The mean is -4 cause u have to add ale the numbers togeter
Answer:
3x + 8
Step-by-step explanation:
Michele's ages is equivalent to x, or 1x. Then you add Kayla's age to Michele's age which now equals 3x. Finally, you add 8, which is Erica's age.
The turtle swims at a speed of 21,120 yards per minute (12 x 5280 = 63,360, 63,360/3 = 21,120) and the boy swims at a speed of 88 yards per minute. So the turtle swims 21,032 yards per minute faster than the boy.
Answer:
Step-by-step explanation:
3x³ + x - 4 - (4x² + 2x - 5) = 3x³ + x - 4 - 4x² - 2x + 5
Now combine like terms
= 3x³ - 4x² + <u>x - 2x</u> <u>- 4 + 5</u>
= 3x³ - 4x² -x + 1
Answer:
y = 3
Step-by-step explanation:
We need to solve the below proportion in this problem,
First of all, we cross multiply both sides such that,
Dividing both sides by 18.
For the above proportion, we find that the value of y is equal to 3.
