The third and fourth grade teachers are planning a trip for their classes to the zoo. There are 173 third graders and 124 fourth graders. Each seat on the buses
fits 3 students
Which expression represents the closest estimate of the number of seats on the
buses that are needed for the students?
(180 -- 130) x 3
(175 - 125) x 3
(180 + 130) = 3
(175 + 125) = 3

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
