Answer:
one solution (-2 ; 5)
Step-by-step explanation:
hello : 2x + 3y= 11
...(*)
-x-5y=-23.....(**)
by(**) : x= -5y+23
put this value into (*) : 2(-5y+23)+3y=11
-10y+46+3y=11
-7y = -35
y=5
but x= -5y+23
so : x= -5(5)+23 =-2
Answer:subtract by 4x on each side first
Step-by-step explanation:
When you do so you'll get 5x on the left side of the equal sign and -5 on the right side. Next you would divide by 5 on both sides and this gives you x on the left side and -1 as your answer on the right side.
1. To answer this question we must keep on mind that we already have the distance from Cleveland to Cincinnati.
2. They tell us that it is 40 centimeters on the first map.
3. If on the first map
then:

4. Then the distance from Cleveland to Cincinnati is 400 kilometers.
5. On the second map 
6. Then we want to know how many centimeters represents 400 kilometers on the second map. Therefore:

The answer is: 8 centimeters.
Now, if you recall, there are 180° in π radians, now, so how many radians in 1°?
Assuming you mean

first term is n=1, so 1²+3=1+3=4
2nd is n=2 so 2²+3=4+3=7
3rd is n=3 so 3²+3=9+3=12
the first 3 terms are 4,7,12
