Answer:
x=15, y=5
Step-by-step explanation:
x+y=20
x-y=10
Adding both equations;
(x+x) + (y-y) = 20+10
2x = 30
x = 30/2 = 15
Substitute x=15 into x+y=20
y= 20-x = 20-15= 5
7+14+21+28+...+105=1*7+2*7+3*7+4*7+...+15*7
15
∑7*n=7*1+7*2+7*3+7*4+...+15*7=7+14+21+28+...+105
n=1
Try this option:
note, that distance between the parallel sides is shown via formula of area.
If it is possible, check the arithmetic.
Answer:
$6,900
Step-by-step explanation:
Let
x = Amount Monica should earn each month
Rent per month = $2,300
Monica knows that she should spend no more than 1/3 of her income on her rent
1/3 of her Income = rent
1/3 of x = 2,300
1/3x = 2,300
x = 2,300 ÷ 1/3
x = 2,300 * 3/1
x = $6,900
Monica should earn $6,900 each month to afford the rent on her cool new place
#4(1)=-1. (2)=5. (3)=14. (4)=26 srry but all i know hoped i helped
[how i did]
the first one i did 3×-5+14 which equals -1
and the second one is the same two 3×-3+14=5 you just add the the number on B
