2x373 because 2 and 373 are both prime meaning they can only be divided by one and themselves
Answer:
C. 10
Step-by-step explanation:
Let x and y represent push-ups and pull-ups, respectively.
x + y = 24 . . . . . . combined total of push/pull-ups
2x +4y = 68 . . . . time required for the exercise
We can divide the second equation by 2 and subtract the first:
(1/2)(2x +4y) -(x +y) = (1/2)(68) -(24)
x +2y -x -y = 34 -24 . . . . . eliminate parentheses
y = 10 . . . . . . . . . simplify
Malia did 10 pull-ups.
__
She did 14 push-ups.
Answer:
C. Greater than.
Step-by-step explanation:
I got 13 but you didn’t put any answer choices
n = d + 3
5n + 10d = 150 cents
Substitute to solve for "d":
5(d+3)+10d = 150
15d + 15 = 150
15d = 135
d = 9 dimes
n = d+3 = 9+3 = 12 nickels
So 12 nickels!!
