The answer would be c. it is a flat Sudanese so you only need to square it
Answer:
11 hours
Step-by-step explanation:
Setting up a system of equations and using the substitution method will give you the number of hours used by each tap. Let a = time for tap A and b = time for tap B:
a + b = 12 (A and B fill a tank in 12 hours)
a = b - 10 (tap A takes 10 hours less than tap B)
Substitute 'b - 10' for 'a' in the first equation:
b - 10 + b = 12
Combine like terms: 2b - 10 = 12
Add 10 to both sides: 2b - 10 + 10 = 12 + 10 or 2b = 22
Divide by 2: 2b/2 = 22/2
Solve for b: b = 11 hours
Answer:
4h+17
Step-by-step explanation:
Hey There!
So to solve this problem we need to use distributive property
So we need to distribute the 3 to everything that is in the parenthesis ( h and 5)
3xh=3h
3x5=15
so now we have
3h +15 + h + 2
now we just combine like terms
3h+h=4h
15+2=17
So the answer is 4h+17
The value of x that will make the proportion true is
