1. The following system has NO SOLUTION. Explain with specific values why the system has no solutions.
y = 4x+5 and 2y=8x+15
Answers
Answer:
Step-by-step explanation:
y = 4x + 5
It is in y = mx + c form
Slope (m) = 4
2y = 8x + 15 {Divide both sides by 2}
[tex]\frac{2y}{2}=\frac{8}{2}x+\frac{15}{2}\\\\y = 4x +\frac{15}{2}[/tex]
Slope = 4
If two lines have same slope, then they are parallel lines.
As you know, parallel lines have never intersect, this system of linear equations have no solution.

find the surface area of the pyramid. The side lengths of the base are equal.
Answers
Answer:
195.6 inches squared
Step-by-step explanation:
First we find the value of one of the big triangles.
(14*8*0.5)
56
Next, we find the value of the three of them combined.
56+56+56 or 56*3
168
Now, we find the value of the smaller triangle.
(6.9*8*0.5)
27.6
Because we only have one small triangle, we don't need to do what we did with the other one now.
The last step is to add the area of the three triangles with the smaller triangle.
168+27.6
195.6
The surface area of the (shape...?) is going to be 195.6 in. squared.

Brody had $29 to spend on 9 beakers for his science class. After buying them, Brody had $2 left. How much did each of the beakers cost?
Answers
Answer:
3
Step-by-step explanation:
29-2=27
27/3=3
Answer:
Each costs $3.
Step-by-step explanation:
To find out how much Brody spent on the beakers in general, you need to subtract the original amount with the new amount. So, you would do 29-2 or $27. Now that you know how much he spent, you need to know how much each costs. Of course each beaker has to cost the same so you would divide. You would do 27/9 and would come up with $3 as your answer. Hope this helped! :)

A car that normally sells for 25,900 is on sale for 84.5% of the actual price. What is the sale of the car?
Answers
Answer:
$21,885.5
Step-by-step explanation:
84.5% of 25,900 =
0.845 * 25,900 =
21,885.5
Because it says that the car is on sale for 84.5% of it's original price means that that is the price of the car.
If it had said that the car was 84.5% off, we would have had to subtracted 21,885.5 from 25,900, however, it didn't so it's ok.

2. A rectangular plot of land has an area of 3/2 sq. kilometers and a length of ¾ kilometers. What is the width of the plot of land?
Answers
Answer:
the width is 2 kilometers
Step-by-step explanation:
total area: 3/2 (kilometers^2)
length: 3/4 (kilometers)
in a rectangle the area is the length multiplied by the width/height
so:
divide 3/4 from both sides to isolate the width:
[tex]\frac{\frac{3}{2}}{\frac{3}{4}} = \frac{\frac{3}{4}w}{\frac{3}{4}}[/tex]
[tex]2=w[/tex] which is the same as: [tex]w=2[/tex]
then just add the units on the end and you're done!

Answers
Answer:
a = -5
Step-by-step explanation:
a = 1/2(-10) + 3^2 - (-1) - 10
a = -5 + 3^2 - (-1) -10
a = -5 + 9 - (-1) - 10
a = 4 - (-1) - 10
a = 4 + 1 - 10
a = 5 - 10
a = -5
x = -1y = 3
z = -10
a = -5

7th and 8th graders at Marshall Middle are going on a field trip. The 7th graders use 10 small buses and 12 large buses for 504 students. The 8th graders use 5 small buses and 7 large buses for 279 students.
1. How many students can fit on a small bus?
2. How many students can fit on a large bus?
Answers
Answer:
by dividing 325 by 48.
The answer comes out to 6.77
But since the number of buses must be a whole number, we will need 7 buses to carry the 325 students and teachers on a field trip.
so the answer is 7 buses
