Answer:
A. 48= 12x + 8y
B. 3 paper back books
Step-by-step explanation:
A. If x represents hardback book, and they are $12 each then that is 12x. y = the paperback books that are $8 each, so 8y. and 48 is the amount that Enola spent.
B. 2 hardback books would equal $24. If you had 3 paperback books that would equal $24. And the two together to get the total amount of $48.
Thomas decides to use the method of proportions and similar
triangles to find the height of a lamppost. He measures the length of
the post's shadow and finds it is 5 feet long. Then, he holds a 1-foot
ruler perpendicular to the ground and finds that it casts a 2-inch
shadow. How tall is the lamppost?
a. 2.5 ft c. 30 ft
b. 12 ft d. 60 ft
Answer:
The lamppost is 30 ft tall.
Step-by-step explanation:
You need to draw a diagram of the problem. Refer to attachment.
Now you need to convert the measurements that are in feet to in. The 1 foot ruler is now 12 in. and the 5 foot post's shadow is now 60 in.
The next step is to create a proportion between both angles. [tex]\frac{x}{1} =\frac{60}{2}[/tex]
x over 1 is simplified to x and 60 divided by 2 is just 30. So the lamppost is 30 ft tall.
Hope that helped. :)

Stacy and Neil painted 280 ft2 of their living room wall with 4/5 gallon of paint. How many square feet can they paint with 4 gallons of paint?
Answer:
56
Step-by-step explanation:
Divide 280 by 4/5 and get 14 then multiply by 4 and get 56
Answer:
1400 ft2
Step-by-step explanation:
if 280 ft2 comes from 4/5 of 1 gallon of paint, then do 280 x 4, because their are 4 gallons of paint. after you x that it will be 1120 ft2. but the extra 1/5 paint from all 4 of the gallons comes out to 4/5 so add 280 ft2 to that 1120 ft2.
it comes out to 1400 ft2.

just use this formula and plug in all your values since im suffering trying to type all of this out on a keyboard but use this formula D= [tex]\sqrt{(x_{2}-x_{1}) + (y_{2}- y_{1} ) }[/tex] if you insert ur points in here you will get distance between each point . hope this helped i think this formula may not be what the question is asking but its the formula to find distance between points so
Henry divided his socks into five groups. Let s represent the total number of socks. Which expression and solution represent the number of socks in each group if s=20?
A. S/5; when s=20, the number of socks in each group is 4.
B. S/5; when s=20, the number of socks in each group is 15.
C. S-5; when s=20, the number of socks in each group is 4.
D. s-5; when s=20, the number of socks in each group is 15.
Pls help
Answer:
A
Step-by-step explanation:
If Henry has 20 socks and he split them into a group of 5, he would have 4 socks in each group. To solve this equation you must divide the number of socks by the number of groups. Once you do this, you will get the number of socks in each group.

the question is below.
Answer: y= x +3
1) find slope using rise over run. Find your coordinates. I used (-3,0) and (0,3). Rise over run with these values : 3-0/0- -3. You should get 1 as a slope after adding and simplifying. Y=1x+b is your equation. Plug in your y and x values to the equation: 3= 0x1 +b. Multiply: 3= 0+b. B is 3( your y intercept). The equation is y=x+3
Answer:y =4,-6 hope this helps you i do my best to helps you and if it did say thanks and if you have anymore questions feel free to ask and plz rate me brainest if it did have a good night
