5) What is

Mathematics
1 answer:
Lera25 [3.4K]3 years ago
8 0

Answer:

x= -2, y=2

Step-by-step explanation:

these are two equations in two unknown variables .. when we find these equations, we do some operations like sum of two equations so here, we will sum the two equation

-5x-y=8

+

5x-3y=-16

__________

0x - 4y = -8

then we have an equation for one unknown variable and it is y, we will divide the equation over the factor of y which is -4

\frac{-4y}{-4}=\frac{-8}{-4}

and we find that y = 2

we will not stop and we will go find the value of x by put y = 2 in any of the two equations because both of them will give us the same solution of x

I chose to put y = 2 in the first equation to be like -5X - 2 = 8

-5X = 8+2

-5X = 10 ( we will divide the equation over the factor of x (-5) )

X = -2

Are 3/5 and 18/32 equivalent ratios? Explain how you know (be specific). If you just say yes or no you will not get full credit.
Artist 52 [7]

Answer:

No

Step-by-step explanation:

As, if we try to simplify 18/32, it will be 9/16

So obviously 9/16 is not equal to 3/5

Here 3 x 6 = 18

5 x 6 = 30

So we will get 18/30, not 18/32
