2(8 4/5)+2(22/25)
2(44/5)+2(22/25)
2(220/25)+2(22/25)
(440/25)+(44/25)
484/25=P

Answer:
x=2/5, y=-3. (2/5, -3).
Step-by-step explanation:
10x+3y=-5
-5x-4y=10
----------------
10x+3y=-5
2(-5x-4y)=2(10)
-------------------------
10x+3y=-5
-10x-8y=20
-------------------
-5y=15
y=15/-5
y=-3
10x+3(-3)=-5
10x-9=-5
10x=-5+9
10x=4
x=4/10=2/5
Answer:
see below
Step-by-step explanation:
2/3 ÷ 4
We use copy dot flip
The flip means make a reciprocal of the second number
2/3 * 1/4
Multiply the numerators
2*1 = 2
Multiply the denominators
3*4 =12
Put the numerator over the denominator
2/12
Simplify
1/6
5x+2=2y+20+24
5x+2=2y+44
-2 -2
5x=2y+42
That's what I got...
