The sum of two numbers is 45. the smaller number is 15 less than the larger number. what is the number

the smaller number is 15, and the larger number is 30

Step-by-step explanation:

Sooo,  s= smaller number and l=larger number

can be solved two ways (using s)

s + s + 15= 45   subtract 15 on both sides

s + s = 30    add both s, which equals 2s

2s = 30    divide both sides by 2

s = 15

( 15 + 15 + 15 = 45)

(you can solve using l)

l - 15 + l = 45   add 15 on both sides

l + l = 60     add both l, which equals 2l

2l = 60    divide both sides by 2

l = 30

( 30 - 15 + 30 = 45)

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
