Answer:
5 bags
Step-by-step explanation:
Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags
The above provides 10pounds of potting soil already
Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil
We know that 1 bag contains 5/8 pounds of potting soil
x bags contain 3 pounds of potting soil
On cross multiplication we get
x = 
since x is an integer x = 5 bags
Note that an extra amount of soil will be remained unused
Answer:
About 30.904 cm.
Step-by-step explanation:
The equation is A=1/2(a+b)h
Where A=22.2
B=8.52
C= 9.86
The teacher spend some amount on buying costumes and microphones for 6 cast members.
<u>GiveN</u><u>:</u>
- Cost of each costume = $38
- Cost of each microphone = $c
- Total money spent = $354
Let's frame the equation. Total money is the total amount spent for 6 cast members.
Money spent on costumes = $38 × 6
Money spent on microphone = $c × 6
<u>Equation:</u>
Taking 6 as common,
Dividing 6 from both sides,
Solving further,
So, the cost of each microphone = <u>$21</u>
The teacher spent this much on each microphone.

Answer:
I think she should get the Verizon house hold Wifi because when you compare the prices even if Monica doesn't want any extra channels she would still save $15. Even tho the extra channel was $4 for the Comcast when you add it up you get $64 instead when you use Verizon even tho you pay $6 for extra channels you still don't get the amount for the Comcast which you save $13 by getting Verizon with $51.
Step-by-step explanation:
CommentThere are 3 ways you could solve this
1. You could graph it.
2. You could equate the line to the quadratic
3. You could just put the x value of the points into both equations until you get the same y value. It sometimes is the only way to solve a multiple choice math question. I do the first two ways.
Step OneGraph the two equations.
The graph is below.
Step 2 From the graph determine the answers.
There are two points where the graphs coincide
Check out D
Step 3Equate the two equations. The y values must be the same.
6x + 6 = -x^2 + 5x + 6
Step 4
Solve
6x + 6 = - x^2 + 5x + 6 The 6s cancel which is very handy.
6x = -x^2 + 5x Pull the 2 terms on the left over to the right.
6x - 5x = -x^2
x = - x^2
x^2 + x = -x^2 + x^2
x^2 + x = 0 Factor
x(x + 1) = 0
That means that
x = 0
or
x + 1 = 0
x = - 1
Step 3Find the ys
y = 6x + 6
if x = -1
y = 6(-1) + 6
y = -6 + 6
y = 0
One of the answers is
(-1,0) <<<<<<<<
Answer
Now for the other one
y = 6x + 6
x = 0
y = 6(0) + 6
y = 6
The other point is (0,6) answer <<<<<<<
D <<<<<< Total answer
