Answer:
Q = 23
Step-by-step explanation:
Complementary angles add to 90 degrees
67+Q =90
Subtract 67 from each side
67+Q -67 = 90-67
Q = 23
Answer:
32 is 99% of 33 cause 33 is 100% of 33
Step-by-step explanation:
Answer:
eric=12
bill=16
Step-by-step explanation:
you can solve this using two simple algebraic equations. this is the key I will be using:
x=bill
y=Eric
x+y=28
x=y+4
since x is by itself in the second equation, I can replace the x in the first equation with y+4
(y+4)+y=28
subtract 4 from both sides
y+y=24
which is also 2y=24
divide both sides by two.
y=12
so now we know Eric is 12 years old.
using this, we can replace the "y" in the second original equation (x=y+4)
x=12+4
x=16
Bill is 16 years old.
Format: y = mx + b
m = slope, b = y intercept
Plug into the format
Solution: y = 5x + 3
