Are the following equations equivalent why or why not Branilist for people who explain
wariber [46]

Answer:

Yes, they are equivilant

Step-by-step explanation:

5(3m+2p)-4m = 13p+11m-3p

Distribute 5: 15m+10p-4m = 13p+11m-3p

Combine like terms: 15m+(-4m) = 11m ; 13p+(-3p) = 10p

11m+10p = 11m+10p

Convert 8.132132132 ... to a rational expression in the form of a over b , where b ≠ 0.
bezimeni [28]

Let <em>x</em> = 8.132132132...

Then 1000<em>x</em> = 8132.132132132...

Subtract <em>x</em> from 1000<em>x</em> to eliminate the fractional part:

1000<em>x</em> - <em>x</em> = 8132.132132132... - 8.132132132...

999<em>x</em> = 8132 - 8 = 8124

<em>x</em> = 8124/999 = 2708/333

Y=-3x+5<br> 5x-4y=-3<br> pls help
salantis [7]

Hello!

\large\boxed{x = 1, y = 2}

We can solve this system using substitution.

Since y = -3x + 5, we can substitute this into the following equation:

5x - 4(-3x + 5) = -3

Simplify:

5x - 4(-3x) - 4(5) = -3

5x + 12x - 20 = -3

Combine like terms:

17x - 20 = -3

Add 20 to both sides:

17x = 17

x = 1

Substitute to find y:

y = -3(1) + 5

y = -3 + 5

y = 2

Solution: (1, 2)

Simplify: 70x/2x.<br> A. 32<br> B. 33<br> C. 34<br> D. 35
Tresset [83]
The answer is D. 35. The x’s cancel out because x divided by x is 1 leaving you with 70/2 which is then 35.
Hope this helped.
