Answer:
x = 30
Step-by-step explanation:
We have to find x
Given that:
20% of x = 12 % of (x +20)
This can be written as:
0.2(x) = 0.12 (x + 20)
0.2x = 0.12x + 2.4
Subtracting 0.12x from both sides we get:
0.2x - 0.12x = 0.12x - 0.12x + 2.4
0.08x = 2.4
Dividing both sides by x we get:
0.08/0.08x = 2.4/0.08
x = 30
Answer:
x = 30
Step-by-step explanation:
Set up an equation:
0.2x = 0.12(x + 20)
Distribute 0.12 and solve for x:
0.2x = 0.12x + 2.4
0.08x = 2.4
x = 30
So, the answer is x = 30

{2x + y = 8
{y = 2x + 4
Answer:
x = 1 and y = 6
Step-by-step explanation:
Add these equations
-2x+y=4
2x+y=8
2y=12
2
y = 6
Plug in 12 for y.
-2x+(6) = 4
-6 -6
-2x = -2
-2

It takes 404040 ink cartridges and 200200200 pages to print a book, and it takes 303030 ink cartridges and 808080 pages to print a magazine. Sarah wants to print books and magazines with at most 300300300 ink cartridges and 120012001200 pages. Let BBB denote the number of books she prints and MMM the number of magazines she prints.
Answer:
40B +30M ≤ 300
200B +80M ≤ 1200
Step-by-step explanation:
The inequality functions are as follows:
For 40 cartridges per book and 30 cartridges per magazine and at most 300 cartridges are used
So the function would be
40B +30M ≤ 300
Now the another would be
There are 200 pages for printing a book and 80 pages are required for printing a magazine also she used at most 1,200 pages
So, the function would be
200B +80M ≤ 1200

A litter of kittens consists of two gray females, one gray male , one black female, and three black males. You randomly pick one kitten. The kitten is gray or male.
Answer:
There is a 3/7 chance for a gray kitten, a 4/7 chance for a male kitten, and a 1/7 chance for a gray male kitten.
Step-by-step explanation:
Total Kittens = 7 (each of the following will be out of the total amount of kittens)
2/7 = Gray Female
1/7 = Gray Male
1/7 = Black Female
3/7 = Black Male
Total Male Kittens = 4/7
Total Gray Kittens = 3/7

Answer:
AE = 30
GD = 5
GF = 10
Step-by-step explanation:
Centroid of medians divide median in the ratio 2 : 1
Therefore,
AG : GE : 2 : 1
Let AG = 2x & GE = x
Since, AG = 20....(given)
Therefore, 2x = 20
x = 20/2
x = 10
GE = x = 10
AE = AG + GE = 20 + 10 = 30
CG : GD : 2 : 1
Let CG = 2x & GD = x
Since, CG = 10....(given)
Therefore, 2x = 10
x = 10/2
x = 5
Since, GD = x
Therefore, GD = 5
BF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10

Answer:
A) 40 + d
B) 45 days
Step-by-step explanation:
A)
total cost = (cost of the air conditioner itself) + (money charged per day)*(days)
cost of air conditioner itself = $40
money charged per day = $1
days = d
40 + 1*d
= 40 + d
B)
total cost = 40 + d
total cost = $85
85 = 40 + d
45 = d
Time used the air conditioner for 45 days.

The point (-3, 15) undergoes a translation of 9 units right and 10 units down. What are the coordinates of the new
point?
(-12,10)
® (-12,5)
(6,10)
D (6,5)
Answer:
This would be D. (6, 5)
Step-by-step explanation:
When moving 9 to the right, you take -3 and add 9 to it, which gives you 6.
Do the same thing with 15, but subtract 10 from it, since you are going to the left. This gives you 5.
Therefore, your answer should be (6, 5)
-3 + 9 = 6
15 + 10 = 5

Answer:
rock climb costs $7
Step-by-step explanation:
2 laser tags +3 rock climb = $31 ( 1 )
4 laser tags + 1 rock climb = $27 (2)
multipy (1) by -2 and add the equations
-4 laser tags -6 rock climb = $ -62
4 laser tags + 1 rock climb = $27
-6 rock climb +1 rock climb = -62+27
-5 rock climb = -35 divide both sides by -5
1 rock climb = $7
