Step-by-step explanation:
x - y + 5z = 29
y + 2z = 4
z = 7
since z = 7 we can use this value in second equation
y + 2×7 = 4 and y = -10
now we know the value of y we can solve the first equation
x -(-10) + 5×7 = 29
x + 10 + 35 = 29
x = -11
Answer:
y = 1/2 x + 3
Step-by-step explanation:
the positive 3 is the y intercept and the positive 1/2 is rise over run up-1 & 2 to the right
You're given two angles and the side not between them are congruent, so the AAS theorem applies. (2nd selection)
Answer:
the third one
Step-by-step explanation:
area of a circle vs. it's diameter
Find the scale factor of the height:
6.5cm / 2.5cm = 2.6
Multiply the known pages by the scale factor:
150 x 2.6 = 390 pieces of paper.
