y= 225 and x= 10
Step-by-step explanation:
You will have to replace y with 3 so it will be 5 times 3 then 15 to the second power to get 225. Now replace a with 2.5 to do 4 times 2.5 to equal 10.
Diana is painting statues. She has 7/8 of a liter of paint remaining. Each statue requires 1/20 of a liter of paint. How many statues can she paint?
Answer:
question is incomplete. A complete question is ----> Diana is painting statues. She has 7/8 of a liter of paint remaining. Each statue requires 1/16 of a liter of paint. find the number of statues.
each statue requires 1/16th of a liter of paint.
so, in a liter , 16th statues can be painted by Diana.
but A/C to question,
she has 7/8 of a liter of paint remaining.
so, we have to find how many statues she can paint in 7/8 litres.
so, number of statues = 7/8 × 16 = 14

Select the correct answer. Nina can stitch of a dress in 4 hours. If d represents the number of dresses and h represents the number of hours, which equation represents this proportional relationship? A. d = 6h B. 3d = 4h C. D. d = 4h E.
Answer: I believe it’s D
Step-by-step explanation:
Answer:
I believe the correct answer would be d= 4h
This is because D is represented as dress and H is hour. So if it takes Nina to make a dress in 4 hours the obvious expression would be per every dress it took 4 hours or in other words d= 4h.
I hope this helps :)

(CL) Perform the operation and simplify the resulting fraction:
c
3/4 c− 7/12 + 7/24 c+ 2/3 − 1 /6 c
Answer:
Step-by-step explanation:
This is just a algebra problem. That means that we need to combine like terms. Variable on one side, number on the other side.
[tex]\frac{3}{4} c-\frac{7}{12} +\frac{7}{24}c+\frac{2}{3} -\frac{1}{6} c[/tex]
Reformat :)
Then we want to make it so that all the fractions have the same denominator.
[tex]\frac{18}{24} c-\frac{14}{24} +\frac{7}{24} c+\frac{16}{24} -\frac{4}{24} c[/tex]
Then combine like terms and solve.
Hope this helps!

"Seven eighths of a number is 63." I need to show my work, but I don't know how to do this. PLZ help!
Answer:
seven eights of a number = 7/8 × a number
let the unknown number be = x
[tex] \frac{7}{8} \times x = 63[/tex]
[tex]x = 63 \div ( \frac{7}{8} )[/tex]
[tex]x = 63 \times \frac{8}{7} [/tex]
[tex]x = \frac{504}{7} [/tex]
[tex]x = 72[/tex]

A plastic bin contains red, yellow, and green key chains. Out of 350 key chains, 10% percent are yellow. Of the remaining key chains, are green. How many red key chains are inside the bin?
A.
26
B.
35
C.
126
D.
189
Answer:
c.126 red
Step-by-step explanation:
red+green+yellow=350
10% out of 350 are yellow
0.1 times 350=35
350-35=315
3/5 out of 315 are green
red is not green so
2/5 of what is left is red
2/5 of 315 is red
2/5 times 315=430/5=126
126 red

speed = distance
time
speed = 8

How do you think the settlers’ desire for more land would affect relations with the Indians? Explain your answer.
Your answer should be at least 5-7 sentences in length.

1.
12 = 3/5
Multiply both sides by 5
60 = 3
Divide by 3
20 = 1
In 1 minute we can scan 20 pages.
2. 4 = 3/8
Divide by 4
1 = 3/32
3. (5/12)/(1/5)
4. 10/ 2.5 = 4
2/5 * 4 = 8/5
1 3/5
