squared is 39 more than the product of 10 and x” ?
F. 2x = 39 + 10x
G. 2x = 39x + 10x
H. x^2 = 390 − 10x
J. x^2 = 390 + x^10
K. x^2 = 390 + 10x
Elena jogged 1 mile more than Marcus. Use a graph
to find the number of miles each person jogged.
Answer:Marcus jogged 7 miles while Elena jogged 8 miles.
Step-by-step explanation:
x + (x+1) = 15
2x+1=15
putting like terms together we get:
2x=15-1
2x=14
hence
x=14/2 = 7miles
therefore we conclude that Marcus jogged 7 miles while Elena jogged 8 miles.
What is the probability that she selects an orange or a pear?
Answer: The probability that she selects an orange or a pear is 7/16.
Step-by-step explanation:
Given number of oranges = 4,
Apples = 9,
Pears = 3,
Total number of fruits = 4 + 9 + 3 = 16,
If she selects a piece of fruit from the box at random,
Then, the probability that she selects an orange or a pear
= The probability of oranges + The probability of oranges
B: 25 Pi
C: 100 Pi
D: 400 Pi
