So we have two equations
x - y = 34
x + y =212
Let's take the first equation and put it in terms of x
x-y+y= 34+y
x= 34 + y
Now that we have a value for x, substitute it into the second equation for x and solve for y.
(34+y)+y=212
34+y+y = 212
34+2y= 212
34-34+ 2y=212-34
2y= 178
2y/2=178/2
y= 89
Now that we know the value for y, we can substitute it into the first equation and solve for x.
x-89=34
X-89+89=34+89
X=123
Y= 89
X =123
ANSWER
Domestic Stamps: 123
Foreign Stamps: 89
The correct answer is <u><em>(2,−1)</em></u>
So..number of times it can be squeezed=volume of tube
3.14*2.25*14=n*15 then solve for n.
98.91/15=n n=6.594 but you round to the nearest whole number so it would be 6 whole squeezes. hope i helped;)
Answer:
200
Step-by-step explanation:
If you do 15/.075 gives you 200 meaning 7.5% of 200 is 15.
You can check your answer by doing 200 × .075 which does give you 15
