200+12m= 644
subtract 200 from both sides
12m= 444
divide both sides by 12
m= 37
he sold 37 albums
Using complementary angles, <X is equal to <Z, so it's <Z = 35°.
26% = 26%/100%
26/100, 13/50
answer is 13/50
Answer:
x=9 and y=3
Step-by-step explanation:
Let's solve your system by substitution.
−4x+6y=−18 and y=−2x+21
Rewrite equations:
y=−2x+21;−4x+6y=−18
Step: Solve y=−2x+21for y:
y=−2x+21
Step: Substitute−2x+21foryin−4x+6y=−18:
−4x+6y=−18
−4x+6(−2x+21)=−18
−16x+126=−18(Simplify both sides of the equation)
−16x+126+−126=−18+−126(Add -126 to both sides)
−16x=−144
−16x
−16
=
−144
−16
(Divide both sides by -16)
x=9
Step: Substitute9forxiny=−2x+21:
y=−2x+21
y=(−2)(9)+21
y=3(Simplify both sides of the equation)
Answer:
x=9 and y=3
Answer:
3
Step-by-step explanation:
The equation is y=Mx+b where m is the slope and b is the y intercept so m=3 so the slope is 3
