$7.50 * 18.5 hrs = $138.75
$7.50 * 20 hrs = $150
138.75 + 150 = 288.75
She raises the price by ¢0.75
So now it is $8.25 per hour
(I guessed on a calculator and got it right)
Multiply 8.25 by 35 and you get 288.75
Your answer is 35

Answer:
(-1, -2)
Step-by-step explanation:
-2x + y = 0
y = 2x
5x + 3y = -11
5x + 3(2x) = -11 => 5x + 6x = -11
11x = -11
x = -1
-2(-1) + y= 0
2 + y = 0 => y = -2

Answer:
The triangle's perimeter is 61.77 inches.
Step-by-step explanation:
Since an altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles, and as a result, the altitude cuts the base into two equal segments, and the length of the altitude is 26 inches, and the length of the base is 9 inches, to find the triangle's perimeter the following calculation must be performed:
Isosceles triangle = 2 equal sides
To obtain the value of the sides, the Pythagorean theorem must be applied on the right triangle formed with the altitude.
(9/2) ^ 2 + 26 ^ 2 = X ^ 2
4.5 ^ 2 + 26 ^ 2 = X ^ 2
20.25 + 676 = X ^ 2
√ (20.25 + 676) = X
√696.25 = X
26.38 = X
26.3865 x 2 + 9 = X
52.77 + 9 = X
61.77 = X
Therefore, the triangle's perimeter is 61.77 inches.
