Answer:
x=17 plz the brainliest!
Step-by-step explanation:
3x+39=90
3x+39-39=90-39
3x=51
\frac{3x}{3}=\frac{51}{3}
x=17
Answer:
answer = -12
Step-by-step explanation:
substitute y as -3 and z as 4
3(-3) - 2(4) + 5
-9-8+5
-17+5
-12
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 8, - 42 ) and (x₂, y₂ ) = (- 3, - 17 ) ← 2 ordered pairs from the table
m =
=
=
= 5
The line crosses the y- intercept at (0, - 2 ) , then
y = 5x - 2 → C
Answer:
Step-by-step explanation:
12+x+10=480
22+x=480
x=458
2(12)+2(x+10)=480
24+2x+20=480
44+2x=480
2x=436
x=218
Answer
If it says = 90 at the end it means that's the answer.
