Answer:↓↓↓Under

Step-by-step explanation:

N.1:

x=4y-5

Substitue 2(4y-5)+3y=23

8y-10+3y=23

11y-10=23

11y=33

y=3

Substitue x=4(3)-5=12-5=7; x=7

N.2:

x+2y=6, x=6-2y

Substitute -3(6-2y)-y=7

-18+6y-y=7

-18+5y=7

5y=25

y=5

1. 2(4y-5)+3y=23
8y-10+3y=23
+10. +10
8y+3y=33
11y=33
divide by 11
ANSWER IS Y=3 X=7
plug y in to find x x=4(3)-5



2. x+2y=6
-2y
x=6-2y
plug into other equation
-3(6-2y)-y=7
-18+6y-y=7
-18+5y=7
+18 +18
5y=25
divide by 5
y=5
plug into other equation to find x
x+2(5)=6
x+10=6
-10 -10
x=-4

Please help ASAP!!!!!!!!!!

Answer:

(c-a, 0)

Step-by-step explanation:

The horizontal space between (c, b) and P is the same as the space between (a, b) and O.

Coordinates are written (x, y), where x is for horizontal space.

P is on the x-axis, making the y-coordinate 0.

(a+c, 0) would be to the right of the entire parallelogram.

(c, 0) would be directly below (c, b).

(a-c, 0) would be to the left of the entire parallelogram and in the other quadrant.

What is 1 5/8 +4 7/8 show work
Anon25 [30]
Take the mixed number apart and have a whole number and a fraction
1+4 and 5/8 + 7/8
1+4=5
5/8 + 7/8 = 12/8
12/8 = 1 4/8
Add 5 to 1 4/8 
5 + 1 4/8 = 6 4/8
1 5/8 + 4 7/8 = 6 4/8
In simplest term, the answer is also 6 1/2
-------------------------------------------------
Another way to solve it is by turning both 1 5/8 and 4 7/8 into improper fractions.
1 5/8 = 13/8
4 7/8 = 39/8
Add them.
13/8 + 39/8 = 52/8
Turn 52/8 into a mixed number.
52/8 = 6 4/8
Simplify it to get 6 1/2.
