Step-by-step explanation: 57=-10z+7 Answer: z=-- -
For the first one the answer is yes
This is a right triangle (you can confirm by using Pythagorean Theorem: 15² + 36² = 39²)
A =
A =
= 15 * 18
= 270
Answer: 270 cm²
X = 3y - 6....so sub 3y - 6 in for x in the other equation
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24
solution is (24,10)
