Answer:
23+7-2x=8x
We simplify the equation to the form, which is simple to understand
23+7-2x=8x
We move all terms containing x to the left and all other terms to the right.
-2x-8x=-23-7
We simplify left and right side of the equation.
-10x=-30
We divide both sides of the equation by -10 to get x.
x=3

The correct answer option is 43%.
<u>Step-by-step explanation:</u>
We are given that 70% of students have blue eyes, 45% have dark hair, and 30% have blue eyes and dark hair.
We are to find the probability of a student getting selected will have dark hair with blue eyes.
P(D|B) = P(D∩B) / P(B)
Substituting the given values in it to get:
P(D|B) = 0.3 / 0.7 = 0.428
Rounding it to the nearest whole percent we get:
0.428 × 100 = 42.8% ≈ 43%

Answer:
So, to answer this problem, we first have to get rid of the cider cost.
$20-$3.50=$16.50
Since we have $16.50 left, now we have to see how much cotton candy grapes Michaela can buy.
1 pound- $3.75
2 pound- $7.50
3 pound- $11.25
4 pound- $15
5 pound- $18.75
When Michaela buys 5 pounds of grapes, she gets a cost of $18.75.
Since $18.75 is $2.25 more than $16.50, the only option she can choose is 4 pounds.
When Michaela buys 4 pounds, she will spend $15 and she will still have $1.50 left. (If there is no tax.)
In summary, Micheala can buy 4 pounds of grapes without spending more than the rest of the money after buying cider.
(By the way, I LOVE cotton candy grapes.)
Hope this helps!
:)
