Mei has 60 milliliters of a solution that is 35% nitric acid. How many milliliters of nitric acid does the solution contain?
(answer this and show your work please)
The solution contains _answer here_ milliliters of nitric acid.
Answer:
21ml
Step-by-step explanation:
60ml. 35% acid. What is 35% of 60 ml?
÷10 to find 10%
60÷10=6
6=10%
But this is no use
because you cannot multiply 10%to get 35%
(35% is not a multiple of 10)
So we try...
10%÷2=5%
So ÷2 to find 5%
6÷2=3
So 3=5%
5%x7=35%
So, we do
3x7=21
So 35%=21
Answer:
21ml
Step-by-step explanation:
Which of the following equations is equivalent to 3(a + 4) – 5(a – 2) = 22?
-2a + 2 = 22
8a + 2 = 22
8a + 22 = 22
-2a + 22 = 22

Solve for x:
(-3/2)x - 9 = -27
Select one:
a. −24
b. −12
c. 11
d. 12
This is what the equation looks like: [tex]\frac{-3}{2}x - 9 = -27[/tex]
First, we transpose the terms to the other side. So after transposing [tex]-9[/tex], you get: [tex]\frac{-3}{2}x = -27 + 9[/tex]
Add them and you get: [tex]\frac{-3}{2}x = -18[/tex]
Next we transpose the coefficient of [tex]x[/tex] which is [tex]\frac{-3}{2}[/tex] to the other side, and while doing so the operation changes to a division. When dividing rational numbers, you take the reciprocal so you get: [tex]x = -18 * \frac{-2}{3}[/tex]
Multiply them and you get: [tex]x = 12[/tex]
Therefore, Option D is the correct answer :D
pls help me i dont understand it.....................
please help I hate imagine math its in the photo
please help! i’m having a rough time on this, could someone answer this question?
Answer:
y= -18
a= -18
Step-by-step explanation:
2y+3 = 3(y+7)
2y+3=3y+21
-21 -21
2y-18=3y
-2y -2y
-18=y

A rectangular poster has an area of 504 square centimeters. The width of the poster is 14 centimeters. How long is the poster?
Answer:
36 sq. cm.
Step-by-step explanation:
We find area by multiplying the length by the width of the poster. But now, in your question we want to find the length of the poster. We are given the area, 504 square centimeters, and the width, 14 centimeters. Since multiplication and division are inverse operations, we will do the opposite of multiplication, division, to find the quotient, the length of the poster. 504 divided by 14 can be written like this: 504 / 14. 504 / 14 = 36 sq. cm. We can check our answer by multiplying 36 and 14 to get 504. So, we know our answer is correct.

A fruit basket contains only apples and bananas. If there are 8 apples and 13 bananas, what is the ratio of bananas to fruit? Select all that apply. 13:8
Answer:
The ratio of bananas to total fruit is 13:21
Step-by-step explanation:
Since we already know the amount of apples and pears, we can find the total. 13+8=21, and since we know the number of pears, 13, we can say that the ratio is 13:21.
Answer: 13:21
Slope-intercept form
find out the y intercept and slope
Answer:
18. Slope (m) = 1/2
Y-intercept (b) = -6
19. Slope (m) = 2
Y-intercep (b) = 8
20. y = 1/2 + 6
Step-by-step explanation:
y = mx + b
y - 2x = 8
y = 2x + 8
