Answer:
A
Step-by-step explanation:
After the first step, which is to do the inverse by dividing both sides by 4.
The equation will look like x-3=48
You the have to do the second step, which is to add 3 (or do the inverse) on both sides (answer A)
since the original price was ninety we have to multiply 5/6 by 90
90/1(5/6)
=450/6
=75
Answer:
310°
Step-by-step explanation:
A rotation changes the position of the polygon but not it's shape.
After the rotation the image and original polygons are congruent.
Thus ∠ B'C'D' = ∠ BCD = 310°
Answer:
6.68%
Step-by-step explanation:
First find the z-score:
z = (x − μ) / σ
z = (13.30 − 13.00) / 0.2
z = 1.50
Look the value up in a z-score table, or use a calculator.
P(z>1.50) = 1 − 0.9332
P(z>1.50) = 0.0668
6.68% of players on the team run the 100 meter dash in 13.30 seconds or faster.
we are given the equation 3y = -7x - 18 and is asked whether y is directly proportional to x and if it is, we find the constant of variation. In this case, we simplify the equation into y = -7/3 x -6. In this case, we can see that y is proportional to x with a constant of proportionality of -7/3
