B=s-15 b=boots, s=shoes
2b+3s=120
2(s-15)+3s=120
2s+3s-30=120
5s=150
s=30$. b=s-15
b=15$
Answer:
4
Step-by-step explanation:
In place value, you would move the decimal point 4 places. You move it 4 places because 10,000 has 4 zeroes.
Answer:
It should be -5
Step-by-step explanation:
Answer:
d. 21.5
Step-by-step explanation:
To find the missing side length of each triangle, use the pythagorean theorem. The theorem is where a, b, and c are all side lengths of the triangle. a is the smallest lef and b is the other leg while c is always the hypotenuse or longest side.
In d, you'll use it twice to find the missing measure. First use it when a = 12 and b = 20. So you'll have:
Repeat the same process using a = 9 and c = 23.32. Then solve for the b value.
Answer:
h(3) = 35
Step-by-step explanation:
Simplify h(t) = 16t - 4t - 1 to h(t) = 12t -1
Then, plug 3 into the t
h(3) = 12*3 - 1 = 36 - 1 = 35
