-3x-8/4=10<br><br> What’s is value of x
dlinn [17]

Answer:

x= -16

Step-by-step explanation:

-3x-8/ 4 = 10

Here we can try to isolate x and so we have to first multiply 4 on each side.

-3x-8= 40

Then we can add the 8 to each side.

-3x= 48

Next, divide the -3 onto each side and we can get the answer!

x= -16

Kelly Ann took 15 minutes to walk from her home to the library. Her average speed was 3 miles in 45 minutes. how far was it from
Anvisha [2.4K]
Ok; Since we know that in 45 min, she can walk 3 miles, we can divide it to see how many minutes it takes for her to walk 1 mile. 45 divided by 3 is 15. Which means it takes her 15 minutes to walk 1 mile. If we look back at the beginning, it says she takes 15 minutes. Now that we know that it takes her 15 minutes to walk 1 mile, the answer is that it takes her 1 mile to walk to the library.

Solve by graphing: use any method<br><br> x + y = 6<br><br> x - y = 4
jekas [21]
X+y=6
x-y=4
using these equations we solve for either x or y in one and plug it into that variable in the other equation.
x=y+4 so y+4+y=6 so 2y=2 so y=1
now using y=1 put into first equation. x+1=6 so x=5 
so we know our graph goes through the coordinate point (5,1) then just make an x table and use some values to find the corresponding y coordinate and then do that for at least three points or more if needed to find the best fit for graph. Hope this helps walk you through it! Any questions please just ask! Thank you!
