Answer:
x = 0.6y.
Step-by-step explanation:
x = ky is direct variation where k is some constant;
Now we find k:-
Substituting for x and y:
9 = k*15
k = 9/15 = 0.6
So the equation is
x = 0.6y.
Answer:
11/2
Step-by-step explanation:
you use the keep, change, flip method so this becomes 11/3 times 3/2 then multiply regularly
Answer:
86.16
Step-by-step explanation:
27+3÷ 3 +4-1+72.4-34.24+6-4+75÷5
PEMDAS
Multiply and divide first
3/3 is 1 and 75/5 = 15
Replace these into the equation
27+1 +4-1+72.4-34.24+6-4+15
Then add and subtract from left to right
31 +72.4-34.24+6-4+15
69.16+6-4+15
86.16
Answer:
(x+1)²= 49, the answer is B
Step-by-step explanation:
x² + 2x = 48
x² + 2x + (2/2)² - (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² - (2/2)²]
(x+1)²= 49, the answer is B
Answer:
the answer is b. It is B. It is B
