Answer:
Y=7 and
X=9
Step-by-step explanation:
X+Y=16
X=2+Y
2+Y+Y=16
2+2Y=16
2Y=16-2
2Y=14
2Y/2=14/2
Y=7
X =2+Y
So X=9
For the second equation solve for x and you will get x= 2y-8 plug that in for the first equation and you will have -24=12 making it no solutions. And for b i would say that y is -2times bigger than x for both equations so that will guarantee both will cancel
Answer:
0>3 i hope it helps
Step-by-step explanation:
Let's solve your inequality step-by-step.
−2(x−3)−4>3x−5(x−1)
Step 1: Simplify both sides of the inequality.
−2x+2>−2x+5
Step 2: Add 2x to both sides.
−2x+2+2x>−2x+5+2x
2>5
Step 3: Subtract 2 from both sides.
2−2>5−2
0>3

Answer:
563.53%
Step-by-step explanation:
Suzanne's cell phone monthly bill = $85
Suzanne's cell phone yearly bill = 85*12 = $1020
Suzanne's student health insurance yearly bill = $181
Therefore,
1020/181=5.63*100 = 563.53%
The money spent on her cell phone bill is 563.53% of the money spent on student health insurance.
On an annual basis, the first set of expenses (cell phone) is 563.53% of the second set of expenses (health insurance)
