Answer:
I believe it would be $34.50.
Step-by-step explanation:
If we need to buy 7.5 lbs of walnuts, and each 3/4 lb is $3.45, we need to divide 7.5 by 3/4
7.5/ .75= 10
10 is how many groups of 3/4 lbs fit into 7.5.
Next, we multiply 10 by 3.45.
10*3.45= 34.5
It costs $34.50 to buy 7.5 lbs of walnuts.
Hope this helps :)
Answer: D=22
Step-by-step explanation:
this is because if multiply f by r you get D and then you do all the other rmathematics and you wind up with 22
Answer:
m = -32.10
Step-by-step explanation:
You solve this the same way you do any two-step linear equation.
1. Subtract the constant that is on the side of the equal sign with the variable term:
m/5 = -6.42
2. Multiply by the inverse of the coefficient of the variable. That means multiply by 5 in this case.
m = 5·(-6.42) = -32.10
_____
Of course, the rules of equality tell you whatever you do to one side of the equation must also be done to the other side. So, when we say subtract 0.12, we mean subtract 0.12 from both sides of the equation. The same for multiplication or division.
Y = 4x
(-2,y).....x = -2
y = 4(-2)
y = -8
