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

Question is below here ⬇️
6. When Landon saves $15 more, he will have enough money to buy a basic MP3 player. The player he wants to buy costs $199, which is 4 times the cost of the basic player. Which equation could be used to determine n, the number of dollars Landon has already saved?
A. 4n +15 = 199 B. 4(n+15) = 199 C. n + 4(15) = 199
Answer:
A) 4n+15=199
Because n is the cost of the basic player, so 4*n would be the cost of the player he wants. Also +15 since he needs 15 more dollars.
Carla makes a scale drawing of her garden that is 30 feet long and 24 feet wide. If the garden in her drawing is 20 inches long, what is its width, in inches?
Answer:
16 in.
Step-by-step explanation:
Notice that 20*1.5 = 30
Use this ratio for 24 except reverse.
16*1.5 = 24
Hope this helps! Have a nice day!
Answer:
16
Step-by-step explanation:
Real length: 30 ft
Drawing length: 20 in.
Real width: 24 ft
Drawing width: x
30/20 = 24/x
3/2 = 24/x
1/2 = 8/x
x = 2 * 8
x = 16
Answer: 16

Tim has 44 blue cubes in a basket.
a. Suppose that he wants 20% to be blue cubes and 80% to be yellow cubes. How many yellow cubes should Tim add?
b. Suppose that he wants 80% to be blue cubes and 20% to be yellow cubes. How many yellow cubes should Tim add?
Answer: Tim should add 35.2 yellow cubes.
