5:7, 15:21. Hope this helps!!!
M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8
Fill in the m's:
1*10-1*2=8
10-2=8
8=8
Hope this helps :)
In exponential form: 10^2=3(x+5)
If we were to solve, x=85/3
Answer:
40:70 becomes 20:35 which becomes 4: 7.
The answer is 4:7
Step-by-step explanation:
Answer:
x= -1.5, y= -1
Step-by-step explanation:
6x= -5+4y
x= (-5+4y) / 6
4((-5+4y) / 6) + 5y = -11
4(-5+4y) + 5*6y = -11*6
-20+16y+30y= -66
16y + 30y = -66+20 = -46
y(16 + 30) = -46
y= -46 / (16 + 30)
y= -46 / 46
y= -1
x= (-5+4(-1)) / 6
x= (-5-4) / 6
x= -9 /6
x= -1.5
