Solve for x 9x-3-8x=7-x

Mathematics
1 answer:
Kipish [7]4 years ago
8 0

Answer:

x = 5

Step-by-step explanation:

First, we move all variables to one side of the equation. (Don't forget to change signs.)    

9x - 8x + x = 7 + 3

Then, we simplify

x + x = 10

2x = 10

10 divided by 2 is equal to 5.

Therefore, x = 5

Hope this helps!

Which of the following angle pairs best describes angles 6 and 4 in the graphic below?
andriy [413]
Answer: Choice C) Same-side interior angles

------------------------------------------------------------------------------

Angle 4 and angle 6 are on the same side, in this case the right hand side of the transversal line (line t). In addition, they are on the interior of the "train tracks" horizontal  lines (line a and line b). Combine this and this is why the two angles are same-side interior angles

Side note: if line a is parallel to line b, then angle 4 and angle 6 add to 180 degrees. At this point, they are considered supplementary.

Whats the cost of each vegetable if 5 squash and 2 zucchini is $1.32​
alex41 [277]

Answer:

Step-by-step explanation:

 

We first need to define a couple of variables.  Let s = the cost of 1 squash and z = the cost of 1 zucchini.

 

Now lets translate the words into algebra:

 

"The cost of 5 squash and 2 zucchini is $1.32"  ===>  5s  +  2z  =  1.32

 

"Three squash and 1 zucchini cost $0.75"  ===>   3s  +  z  =  0.75

 

There are several ways to solve systems of equations.  Let's use substitution.  We can find what z equals in terms of s by manipulating the second equation:

 

 3s  +   z   =   0.75

-3s                 -3s

------------     -------------

           z    =  -3s  +0.75

 

Now lets substitute (-3s + 0.75) into the first equation for z, then solve for s:

 

 5s + 2(-3s + 0.75) = 1.32

 

Can you handle it from here?

 

(Hint: Once you have solved for s, you can substitute that value back into either of the equations and solve for z.)
