We have that if we add 4 to the number of charter schools, we have twice the number of the alternative schools in the county. Hence, twice the alternative schools are 52. The half of this is 26. Hence, there are 26 alternative schools in the county. These steps correspond to solving the expression 48=4+2x.
Answer:
Step-by-step explanation:
Answer:
x = 42
y = 38
Step-by-step explanation:
for y:
there is a corresponding angle at 58° so y + 20 must equal to 58. ∴y = 38°
for x :
first locate the straight angle at CD. The angle opposite 58° must also be 58° as it is vertically opposite. We have two values here.. 58° and 22°. Use your knowledge of straight angles and add 22 + 58, which equals to 80. Now subtract from 180 which = to 100°. We know that the angle sum of a Δ is 180° so add 38 and 100, which will give you 138°. Subtract from 180 to give you a total of 42°
Sorry if this was very lengthy haha
hope it helps:)
Answer: y = (x+2)^2
Aka: B
Step-by-step explanation:
Did it on edge just now !
This is a 4 step problem.
Find the probability of drawing a green marble the first time
<em>8 green marbles ÷ 17 total marbles </em>
Next, we find the probability of drawing a green marble the second time
<em>7 green marbles ÷ 16 total marbles </em>
Find the probability of drawing a green marble the third time
<em>6 green marbles ÷ 15 total marbles </em>
We<u> take away one</u> from the total marbles and green marbles each time because we are finding the probability that we draw a green marble <u>all three times </u>
Last step:
Multiply all the probabilities
× 
× 
The final answer is 7/85 or an 8% chance
If you were curious, the decimal version of this answer is <u>0.08235294</u>
