5x+8=2x -13 ?
i need help please
Answer:
x=-7
Step-by-step explanation:
Alrighty. 5x+8=2x-13. Lets do -2x on both sides. We'll get 3x+8=-13. Then lets subtract 8 from both sides. We'll get 3x=-21. Divide by 3 and we'll get x=-7. Hope that makes sense.

Page 5. 5, 6, 7, 8
Page 6. 12.5
Page 7. 4(3x)
Page 8. 0, 4
i don't know number 7
Answer:
9, 10
12.5
4 + 3x
0, 4
Step-by-step explanation:
5. This just looks to be some simple multiplication so lets work this out 1 by 1 .
Plugging each answer possible into m this is what we get :
8 x 5 = 40
8 x 6 = 48
8 x 7 = 56
8 x 8 = 64
8 x 9 = 72
8 x 10 = 80
Considering these answers lets find which ones are GREATER than 67.
That would be :
72, 80
So your answers would be :
9, 10
6. Alright so this one is asking you what the value of q would be in the equation :
0.5q = 6.25
So to find q we need to see that whatever q is will be multiplied by 0.5. And this answer will be equal to 6.25 due to the = sign. So an easy way of doing this is actually just finding what 6.25 x 2 is. Since q x 0.5 will equal to 6.25, finding 6.25 x 2 is just flipping the equation in a way.
So doing this we get 12.5 which is the very top answer of that question.
8. Alright so it looks like this question is just meant to make your brain turn into a raisin when you read it, but it isn't that hard.
Lets lay everything out :
Joe is 4 more than triple the age of luke.
x represents lukes age (x = Lukes age)
And we are finding the expression that shows joes age.
Alright so looking at the problem lets look at the key word MORE. More means addition in the math world usually so lets go off that. Lucky for you that's all you need cause you only have one addition answer here but lets still go over it why don't we.
4 + 3x
4 represents the "4 MORE than lukes age"
Then we have 3. The 3 represents the "triple the age of luke"
And finally x represents Lukes age.
So if we do 3 multiplied by x (Lukes age) we get triple lukes age :
4 + (Triple lukes age)
So now we just add the 4 and it would be in theory :
Triple Lukes age + 4 = Joes age. And that's all they want.
And then finally we have 7.
This is one fairly simple just another one meant to confused you a bit it seems.
You're basically taking the variable which is q and adding +2 to it and checking to see if the sum of that is less than 7.
So lets do that with the answers given
We will just input the number where q is in the equation and then check! :
2 + 0 < 7
2 plus 0 is 2, and is less than 7!
2 + 4 < 7
2 plus 4 is 6, and is less than 7!
2 + 5 < 7
2 plus 5 is 7. It would be correct if there was an equal sign or less than or equal to sign. But there is not so this is incorrect.
2 + 7 < 7
2 plus 7 is 9, which is greater than 7.
2 + 9 < 7
2 plus 9 is 11, which is greater than 7.
So lets look at what we plugged in that is less than (<) 7 and those are our answers! :
0 , 4
The others are either equal or greater than 7 which is not what we are looking for. So the only two correct answers here are 0, 4.
I hope this helps you! If you have any questions feel free to ask them in the comments and I will help you the best I can! :)
What is an
equation of the line that passes through the points (-3,7) and (3, 3)?
Find the measure of angle 1
hurry
Answer:
112 degrees
Step-by-step explanation:
This is a quadrilateral, meaning 4 sides. The sum of the angles of a quadrilateral is 360 degrees. You are given the right angle, or 90 degrees, and the 46 degree angle at the bottom. Since the two lines on either side of the 46 degree angle represent parallelism, angles 1 and 2 are the same.
360 - (90+46) = 224.
224 / 2 = 112.
Answer:
[tex]m∠1 = 112[/tex]
Step-by-step explanation:
[tex]m∠1 = m∠2[/tex]
[tex]m∠1 + m∠2 + 90 + 46 = 360[/tex]
[tex]m∠1 +m ∠2 + 136 = 360[/tex]
[tex]m∠1 + m∠2 = 360 - 136[/tex]
[tex]m∠1 + m∠2 = 224[/tex]
[tex]m∠1 = \frac{224}{2} [/tex]
[tex]m∠1 = 112[/tex]
[tex]m∠2 = \frac{224}{2} [/tex]
[tex]m∠2 =112[/tex]
To find the population of a city next year, we multiply its current population by 0.987. By what percent does the population decrease per year?
Answer:
1.3%
Step-by-step explanation:
If we multiply a city's current population by 0.987 to get its population for the next year. Each year, the population decreases by 1.3 percent.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol. The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages.
Suppose x₁ is the population of the year 1. As a result of the given condition the population of a city next year,x₂ is
x₂=0.987 x₁
The decrement in the percentage is found by the following formula,
% r = x₁-x₂/x₂
% r =x₁-0.987x₁/0.987x₁
% r =1.3 %
Thus, if we multiply a city's current population by 0.987 to get its population for the next year. Each year, the population decreases by 1.3 percent.

What is the greatest common factor of 42 and 50?
Answer:
2 is the gcf of 42 and 50
The greatest common factor of 42 and 50 is: 2
How to find the Greatest common factor?The greatest common factor, the name implies, is the greatest among all common factors among the quantities.
We have to factorize the quantities in the smallest relative factors possible (one level of factors over which all quantities can form themselves) and collect as many common factors as we could.
Those will together compose GCF.
Take out the factors of the numbers given:
42: 1, 2, 3, 6, 7, 14, 21, 42
50: 1, 2, 5, 10, 25, 50
The common numbers between the two are 1 and 2, but the greatest number is 2, which becomes the greatest common factor.

Answer:
-6x⁶ + 4x⁴ - 3x³ + 4x² + 12
Step-by-step explanation:
To write an equation in standard form, you want to arrange the terms from increasing to decreasing powers/exponents.
given: 4x² - 6x⁶ + 2x³ + 12 - 5x³+ 4x⁴
First, lets arrange like terms together. Put the terms with the same exponent together.
2x³ - 5x³ + 4x² - 6x⁶ + 12 + 4x⁴
Now combine the terms with the same exponent by subtracting 5x³ from 2x³.
-3x³ + 4x² - 6x⁶ + 12 + 4x⁴
Now let's arrange the terms from increasing to decreasing powers/exponents.
-6x⁶ + 4x⁴ - 3x³ + 4x² + 12
This is your equation in standard form.
