Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Mia solved the equation and determined that m = 2. Is she correct?
Answer:
No, Mia is not correct, the answer is -2.
Step-by-step explanation:
First we are going to use the distributive Property.
Step 1: 2(0.75+0.4). multiply the 2 out. .75m x 2=1.5m and 2 x .4= .8.
We get 1.5m+.8, so 2(0.75+0.4)=1.5m+.8
Now we are going to distribute on the oher side. 4(.5m-.8)
4x .5m=2m and 4x.8=3.2. Keep the sign the same and we get 2m-3.2, so 4(.5m-.8)=2m-3.2
We put this into the new equation to get 1.5m+.8+7.8=-6.4m+2m-3.2
Step 2: combine like terms
.8+7.8= 8.6 and -6.4m +2m =-4.4m
Plug that into our equation and we get 1.5mn+8.6=-4.4m-3.2
Step 3: Switch the sides
Bring -4.4m to the other side to get 1.5m+4.4m=5.9m
One side is 5.9m
We bring 8.6 to the other side to get -8.6. now we do -3.2-8.6=-11.8.
Our new equation is 5.9m=-11.8
divide by 5.9 on both sides to get our answer of
m=-2

Naomi buys an antique dresser for $1200. Each year, it appreciates (increases in value) by 3.5%. Write an equation to determine its value V(n) after n number of years
9514 1404 393
Answer:
V(n) = 1200·1.035^n
Step-by-step explanation:
The value multiplies by 1+3.5% = 1.035 each year. After n years, that growth factor has been applied n times, so the value is ...
V(n) = 1200·1.035^n

Choose the following ratios as a percent: 30 days out of 100 days
10%
30%
100%
3%
Answer:
30%
Step-by-step explanation:
30% of 100 in simple terms stands for; "Thirty percent of a hundred."
This shows the ratio percentage correctly. And other choice would not be correct.
100% of 100 has nothing to do with 30.
3% is "three percent of 100." And again, has nothing to do with thirty.
10% also has nothing to do with thirty.
