1.5a+1.25b=28 (2)
Sub 1 into 2
1.5(20-b)+1.25b=28

-0.25b=28-30
-0.25b=-2
b=-2/-0.25
b=8

a=20-8
a=12
Because 1.5•12= 18 so then take 1.25•8= 10 then add 18+10 which equals 20 when added together

The formula for a triangle is base x height x 1/2
The triangles on the top and bottom have a base and height of 6 and 12 so: 6x12x1/2= 36 There are 2 of them so: 36 + 36 = 72
The triangles on the sides have a base and height of 8 and 14 so: 8x14x1/2=56 There are also 2 of them so: 56 + 56 = 112
The formula for the area of a rectangle is length x width
The length and width of the rectangle is 6 and 8 so: 6 x 8 = 48
Now add up all of the areas: 72 + 112 + 48 = 232

second one. 5x + 8 + 2 + 3x
third one. 1x + 9x + 4 + 4
fourth one. 6 - 7x + 9 - 2x
last one. 14 - 4x + 3 - 1x
Answers
Answer:
1. -13x + 11
2. 8x + 10
3. 10x + 8
4. -9x + 15
5. -5x + 17
Step-by-step explanation:
In the first problem, you have to do -5x + -8x which is -13x. Then you add 2+9 which is 11. You will get the expression -13x + 11.
In the second problem, you have to do 5x + 3x which is 8x. Then you add 8 + 2 which is 10. You will get the expression 8x + 10.
In the third problem, you have to do 1x + 9x which is 10x. The. you add 4 + 4 which is 8. You will get the expression 10x + 8.
In the fourth problem, you have to do -7x + -2x which is -9x. The. you add 6 + 9 which is 15. You will get the expression -9x + 15.
In the last problem, you have to do -4x -1x which is -5x. The. you add 14 + 3 which is 17. You will get the expression -5x + 17.
2. 8x + 10
3. 10x + 8
4. -9x + 15
5. -5x + 17

Carlos bought 80 feet of rope for $17.60. He needs 20 more feet. If the unit price is the same how much will he pay for the extra 20 feet of rope? Show each step of your solution and explain your reasoning.
Answers
Answer:
$4.40
Step-by-step explanation:
ok so this is an instance of proportional relationships, in this case we changed one side of this equation, and now we need to figure out how to change the other side the that the change is made on both sides of the (=)
heres what we know
$17.60 = 80ft.
$??.?? = 20ft.
to help us find the change we can divide the first known side with second known side as shown below
80 / 20 = 4
so now we know that 80 was divided by 4 to get 20, so now we can divide the other side by the same amount to get...
$17.60 / 4 = $4.40
so it costs $4.40 for 20 ft. of rope
EXTRA: just because we can, lets figure out what 1 ft of rope costs using the same method as show above (starting with 20 ft)
20 / 1 = 20
$4.40 / 20 = $0.22
so the rate at wich the rope is sold is 22 cents a foot

One cubic foot of a crushed mineral weighs 160 pounds. How many pounds of the crushed mineral can a container with the dimensions shown hold?
The container can hold__pounds of the crushed mineral.
Answers
3600 pounds
Step-by-step explanation:
One cubic foot of a chemical weighs 60 pounds.
1 ft³ of chemical = 60 pounds
We need to find how many pounds in the container whose dimension 6 ft, 4 ft and 2.5 ft
l = 6 ft
b = 4 ft
h = 2.5 ft
Volume of box = lbh
= 6 x 4 x 2.5
= 60 ft³
As we are given
1 ft³ of chemical = 60 pounds
60 ft³ of chemical = 60 x 60 = 3600 pounds
Hence, In container contains 3600 pounds of chemicals.

What is a prediction you can make from the type of music Joey will hear when he randomly plays a song from his playlist? (what can we do to try to figure this out?)
A.The song is 3 times as likely to be rap as it is R and B
B.The song is 2 times as likely to be country than it is R and B
C.The song is half as likely to be rap as it is all other songs combined.
Answers
County is 20 where R and B is 10, therefore the song would be 2 times as likely t be country than it is R and B.

Hey doing-the-homework-at-the-last-minute-student!
Here's how you gotta do it:-
[tex]\frac{5}{6}[/tex] - [tex]\frac{5}{12}[/tex]
Both the denominators should be same to be subtracted.
So, let's multiply [tex]\frac{5}{6}[/tex] with 2 so that its denominator will be 12 as well.
[tex]\frac{5}{6}[/tex] x [tex]\frac{2}{2}[/tex]
[tex]\frac{10}{12}[/tex]
Now, lets subtract this with [tex]\frac{5}{12}[/tex]
[tex]\frac{10}{12}[/tex] - [tex]\frac{5}{12}[/tex]
While subtracting, you don't have to subtract the denominators. Only find the difference between the numerators- 10 and 5.
10-5 is 5.
So,
[tex]\frac{10}{12}[/tex] - [tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]
[tex]\frac{5}{12}[/tex] is the answer!
