53 = -19z + 5 + 7z
53 = -12z + 5
12z = 5 - 53 = -48
z = -48/12 = -4
z = -4

Answer:
B. 7m
Step-by-step explanation:
She has 7 classes a day (3+4), and each takes the same number of minutes. If m stands for minutes per class, you can find the total minutes per day by multiplying 7 by m. Therefore the answer is 7m.
Example: Let's say a class takes 30 minutes, you would put 30 in the place of m, 7x30=210, so she would be teaching 210 minutes of yoga class each day.
Answer:
x = 90 , y = 43
Step-by-step explanation:
Since AB and AC are congruent , then Δ ABC is isosceles with base angles congruent , that is
∠ ABD = ∠ ACD = 47°
AD is the perpendicular bisector of BC , so
∠ ADB = x = 90
the sum of the 3 angles in Δ ABD = 180° , then
y = 180° - (90 + 47) = 180 - 137 = 43
Step-by-step explanation:
b=70
c=70
a=70
they are all 70 because they are alternate angles. they are alternate to each other.
