Answer:
z = -5
Step-by-step explanation:
3(0.7z + 2.8) = 7(1.5z + 7.2)
2.1z + 8.4 = 10.5z + 50.4
2.1z - 10.5z = 50.4 - 8.4
-8.4z = 42
z = 42/(-8.4)
z = -5

Answer:
(0, 4) or any point on the line y=3x+4
Step-by-step explanation:
Find the slope of the equation
<u>7 3/4-6 1/4</u>
1 1/4-3/4
Which is 1.5/0.5, which simplifies to 3. Plug that slope into the equations.
y=mx+b, 6 1/4=3*3/4+b, b=4.
Now the equation is y=3x+4
Any point on this line is a solution, such as (0, 4)
Step-by-step explanation:
angles are equivalent to 65 degrees :
<2, <4 & < 8
