First you add 3x+x because they are like terms.
3x+x-7=10
Your New Simplified Equation:
4x-7=10
Now, you have to take out the -7 by adding a positive 7. Also you have to add +7 on the other side so add 7 to 10.
Your New Simplified Equation:
4x=17 Now, you divide both sides by 4.
Your New Simplified Equation:
x= 17/4 So, that's your answer :)
Solve the system.... 2y+8x+58 and y-5x=11
Answer:
x=2, y=21
Step-by-step explanation:
there are two methods: substiution and elimation. I will be doing subtistution in this soultion:
first isolate y in either equation, it would be easier to do it in the second one.
y= 11+5x
Then, subtitute that into the first equation
2(11+5x)+8x=58 (it says 2y+8x+58 but I assume you mean 2y+8x=58?)
22+10x+8x=58
18x = 36
x=2
substitute that back into y = 11+5x, to get y=11+10 = 21

Seven people are going to share an 84-ounce bottle of soda.
Let x be the number of the ounces bottle of soda of each person.
Then we have the equation will be
7x = 84
x = 84 / 7
x = 12
Then the number of ounces will each person get to drink will be 12.

The cost to manufacture a hair clip is $0.50. With a markup of 200%, what is the selling price of this hair clip?
Answer:
Step-by-step explanation:
The cost to manufacture a hair clip is $0.50. With a markup of 200%, what is the selling price of this hair clip?
Given data
cost to manufacture a hair clip is $0.50
markup of 200%
Required
The selling price
We know that
Mark up percent= selling-cost/cost*100
200= selling-0.5/0.5*100
200-selling= 50/0.5
200-selling= 100
selling= 200-100
selling = 100
Hence the selling price is $100

If 8x−5y=−3 is a true equation, what would be the value of 8x−5y+7?
Answer:
Value of 8x -5y + 7 is 4.
Step-by-step explanation:
Given that:
8x-5y = -3 Eqn 1
It is a true equation.
Now we have to find the value of the given expression
8x -5y + 7
Putting value of 8x-5y from Eqn 1 in the given expression
8x - 5y + 7
-3 + 7
4
Therefore,
8x - 5y + 7 = 4
Hence,
Value of 8x -5y + 7 is 4.

9. Factorize: 6x2 - 19x + 14.
Answer:
Step-by-step explanation:
Here, we want to factor the given polynomial
We have this as;
6x^2 - 19x + 14
= 6x^2 -12x-7x + 14
= 6x(x-2) -7(x-2)
= (6x-7)(x-2)
6x^2-19x + 14 = (6x-7)(x-2)

Katie's business is going so well she wants to expand and add a shirt. She makes an isosceles triangle logo like the one below.
What is the angle of B
What is the value of j?
___°
34 degrees.
If you want to find how much an angle is, first check the original line (aka base). Then (only if the line is a 180 degree line) subtract whatever value is shown (in this case it was 146 degrees so what you would do is subtract 146 from 180 and you would have your answer).
Hope this helps.
