Answer:
5
Step-by-step explanation:
15a , 10b , and -7b are coefficients.
Answer:
A
Step-by-step explanation:
First I converted the fractions into decimals to make it easier to solve.
2 1/2 —> 2.5
1 3/4 —> 1.75
Then I added the two decimals together.
2.5 + 1.75 = 4.25
Then I divided this number by 100 (the number of cups in one bag)
100/4.25=23.529
With this equation I know that one bag lasts 23 full days.
This is almost a month, and so it would not make sense for the answers to be B, C, or D.
Hope this helped

Answer:
∠B ≅ ∠Y △ABC ~ △ZYX by the SAS similarity theorem.
Step-by-step explanation:
1.
units

units
units, then
![\dfrac{AB}{ZY}=\dfrac{BC}{YX}=2](https://tex.z-dn.net/?f=%5Cdfrac%7BAB%7D%7BZY%7D%3D%5Cdfrac%7BBC%7D%7BYX%7D%3D2)
2.
and
are right angles - given
3.
two right angles are always congruent.
4.
by SAS similarity theorem.
SAS Similarity Theorem states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar.
