Answer:
B) She is incorrect because when substituting 2 for m the result was a false statement.
Step-by-step explanation:
Let's solve it for ourselves and see if Mia is correct:
7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8)
7.8+1.5m+0.8=-6.4m+2m-3.2
1.5m+8.6=-4.4m-3.2
8.6=-5.9m-3.2
11.8=-5.9m
-2=m
m=-2
Since the answer is actually m=-2, Mia's guess is incorrect because plugging in m=2 does not make both sides equal. Therefore B is the correct option.
12*3 sunny days= 36 worms
12-4=8 worms eaten on ONE rainy day
8*4 rainy days=32 worms
32+36=68 worms eaten that week

Answer:
(-4, 24)
(-2, 18)
(0, 12)
(2, 6)
(4, 0)
Step-by-step explanation:
You need to plug the domain values into the function for x to find the range, which is the y.
f(x) = 12-3x
So for -4, it would be f(-4) = 12 - 3(-4) = 24, and do the same with the other values.
Answer:
Step-by-step explanation:
I'm guessing your talking about long division,so to divide you Step 1: D for Divide. How many times will 5 go into 65? ...
Step 2: M for Multiply. You multiply your answer from step 1 and your divisor: 1 x 5 = 5. ...
Step 3: S for Subtract. Next you subtract. ...
Step 4: B for Bring down. ...
Step 1: D for Divide. ...
Step 2: M for Multiply. ...
Step 3: S for Subtract.
If its long you still do the same thing and if the decimal is in the divisor then you move the decimal that many times to the inside the bracket and stop at where the problem tells you or just leave it in its hundreths.
