Answer:
Bryan spent $45 on flowers. The last sentence isn't needed to answer this question.
Step-by-step explanation:
If you multiply 10 by 2, then 5 by 5, and add it at the end you get 45.
Answer:
33%
Step-by-step explanation:
Why it is 33% is you minus 20 and 30 to get 10 then you just put that on top of 30 to get 10/30 and you will get 33%.
8/10-the length of the street minus 4/10-the completed amount equals 4/10 of a mile is the remaining. Since the denominators are the just sub the numerator.
(36(0.45) + x)/(x+36) = 0.6,
x + 16.2 = 0.6x + 21.6,
x = 13.5 grams of pure syrup should be added

Answer:
a) 7(3x +7)
b) y(3y -1)
c) 4x^2(2 +x)
d) 2s^2t^2(12s +5t^2)
Step-by-step explanation:
These are factored by finding the greatest common factor of the given terms. Generally, that can be found by looking at the factors and finding the largest that is common to all terms.
__
a) 21 = 7·3; 49 = 7·7. The GCF is 7. Factoring that out gives ...
7(3x +7)
__
b) y is the only factor common to both terms.
y(3y -1)
__
c) 4 and x^2 are factors common to both terms, assuming the second term is 4x^3.
4x^2(2 +x)
__
d) 10 = 2·5; 24 = 2·12; the factors s^3 and s^2 share a factor of s^2; the terms t^2 and t^4 share a factor of t^2.
2s^2t^2(12s +5t^2)
