Line v passes through point (6, 6) and is perpendicular to the graph of y = 3/4x – 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
a. y = 3/4x + 2
b. y = –3/4x + 2
c. y = 4/3x + 2
d. y = –4/3x + 2
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
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.

Jane is helping the librarian stack books on some new shelves. She is to stack 116 books on 16 shelves. The librarian told her to put the same number of books on each of the 16 shelves.
Describe one way that Jane can use to determine the number of books she should put on each shelf.
Answer:
She should divide The total of books to the total of shelfs
Step-by-step explanation:
Answer:
she can put 7 on each shelf with 4 left over.
Step-by-step explanation:
You divide 116 by 16, which is 7.25 and 1/4 of 16 is 4. So you know you have 4 leftover.
Order the values from least to greatest.
Answer:
just value it least to greatest

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.
