1/4 =non chocolate bar
3/4 = chocolate bar
45 ÷ 3 = 15
So 1/4 = 15 candy bars
And 1/5 candy bars contained nuts...
45 x 1/5 = 9 chocolate bars contained nuts
The answer is ...
15 non chocolate bars
And
9 chocolate candy bars contained nuts
Answer:
26 = 5 + (r×3)
26 - 5 = 21
21 ÷ 3 =
7
7 is the amount of rides you went on at the fair
Answer:
<h2>The probability of first one to be blue is

.</h2>
Step-by-step explanation:
In the given box, there are 4 red markers and 2 blue markers.
The given scenario will not affect the required probability as the selection of the second one is a case of future.
We need to find the probability of the first marker is blue.
The probability is
.
Answer:
8) <em>x</em>=9
10) 23 degrees
Step-by-step explanation:
8) vertical angles are congruent to each other so we can set the expressions as such and solve:
<u>7x</u> + 3 = <u>10x</u> - 24
<u>3</u> = 3x<u> - 24</u>
<u>27</u> = <u>3x</u>
9 = x
10) since the angles are complementary they equal 90 degrees, so we can set the expression like this and solve for <em>x</em>:
<u>12x</u> + 7 + <u>6x</u> - 7 = 90
18x <u>+ 7 - 7</u> = 90
<u>18x</u> = <u>90</u>
x = 5
now we plug it back into the expression equivalent to the measure of angle O:
<u>6(5)</u> -7
<u>30 - 7</u>
23 degrees

Answer:
see attachments
Step-by-step explanation:
These are "one-step" equations.
To solve the ones involving addition or subtraction, identify the constant on the same side with the variable. Add its opposite to both sides.
To solve the ones involving multiplication or division, identify the coefficient of the variable. Multiply both sides by its reciprocal (or, equivalently, divide by that coefficient).
Here are more details for the problems on the first page.
- w +8 = -3 ⇒ w = -3 -8 = -11
- z +(-7) = -20 ⇒ z = -20 +7 = -13
- 1/5x = 11 ⇒ x = 5·11 = 55
- 1u = -88 ⇒ u = -88/11 = -8
- 1/9y = -2 ⇒ y = 9(-2) = -18
- 12 +n = 7 ⇒ n = 7 -12 = -5
- q +(-4) = 8 ⇒ q = 8 +4 = 12
