Step-by-step explanation:
x+y=180
x=180-y------(i)
x-y=70------(ii)
Now,
Putting the value of x in equation (ii)
x-y=70
(180-y)-y=70
180+2y=70
2y=70-180
2y= - 110
y= - 110/2
y= - 55
Again,
x=180-(-55)
x=235
x-y=70
x-(-55)=70
x+55=70
x=70-55
x=15
Answer:
welll I don't know how to do that and i don't know how to back out of an answer i am sorry i do not want to be just a "point stealer" i thought I knew how to do this. I am so so so sorry
Step-by-step explanation:
and I hope you find the correct answer!
Y = kx, where k is the constant of proportionality.
We need to find k as our first step.
35 = k140
35/140 = k
1/4 = k
We can now find y when x = 70.
y = kx
y = (1/4)(70)
y = 70/4
This fraction can be simplified or reduced more.
The number 2 is the GCF of 70 and 4.
70 ÷ 2 = 35
4 ÷ 2 = 2
Answer:
y = 35/2
Answer:
45%, 1/2, 0.6, 12
Step-by-step explanation:
45% out of 100 would be 45.
1/2 Of 100 is 50
0.6 of 100 is 60
12 of 100 is 120
