Answer: 4
Step-by-step exzplanation: 20/360= X/72
360X= 1440
Divide by 360
X=4
Answer:
the answer is 6.1
Step-by-step explanation:
h= A over B (means you divide) and you get 6.1
Answer:A
Step-by-step explanation:
23/50= 0.46 *100= 46%
Haileys work is correct so B should be the right answer
Answer:
x=-4 y=-1
Step-by-step explanation:
Let's solve your system by substitution.
−3x−8y=20;y=5x+19
Rewrite equations:
y=5x+19;−3x−8y=20
Step: Solve y=5x+19for y:
y=5x+19
Step: Substitute5x+19foryin−3x−8y=20:
−3x−8y=20
−3x−8(5x+19)=20
−43x−152=20(Simplify both sides of the equation)
−43x−152+152=20+152(Add 152 to both sides)
−43x=172
−43x
−43
=
172
−43
(Divide both sides by -43)
x=−4
Step: Substitute−4forxiny=5x+19:
y=5x+19
y=(5)(−4)+19
y=−1(Simplify both sides of the equation)
Answer:
x=−4 and y=−1
