Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50
Answer:
- Point W = (-3, 3)
- Point X = (-3, 2)
- Point V = (-2, 3)
<em>The rotation rule states that rotation 90° counterclockwise means (x, y) = (-y, x)</em>
<u>The new points would be equal to:</u>
- Point W' = (-3, -3)
- Point X' = (-2, -3)
- Point V' = (-3, -2)
Try graphing it to see if the new points make sense<em>(because I'm not too sure :\)</em>
Answer:
P(drama) = 1/2 or 50%
Step-by-step explanation:

Answer with Step-by-step explanation:
Let there be d dimes and q quarters
A woman has 21 total coins in her pocket.
⇒ d+q=21 ------(1)
1 dime=$ 0.1
1 quarter=$ 0.25
The total value of her change is $3.90
⇒ 0.1d+0.25q=3.90
Multiplying both sides by 100,we get
10d+25q=390 --------(2)
(2)-10×(1)
10d+25q-10d-10q=390-210
15q=180
Dividing both sides by 15, we get
q=12
Putting value of q in (1),we get
d=9
Hence, Number of dimes=9
and number of quarters=12
Write the number of dimes, then the number of quarters separated by a comma.
9,12
