Answer:
7x - 8
Step-by-step explanation:
5x + 2 + 2x - 10
Rearrange terms:
5x + 2x - 10 + 2
Combine like terms (add 2x and 5x):
= 7x - 10 + 2
Combine like terms (add -10 and 2):
= 7x - 8 (This is the simplified form).

The difference of the given expression is 3/20 x - 3.
Given that, (2/5x−1)−(1/4x+2).
What is the subtraction of expressions?To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.
Now, (2/5x−1)−(1/4x+2)
= (2/5 x - 1/4 x) -1 - 2
= (8/20 x - 5/20 x) - 3
= 3/20 x - 3
Therefore, the difference of the given expression is 3/20 x - 3.

Hi, i am in 8th grade math and i really just need someone to explain the steps on how to slove these types of quetsions-
1. -12(k+4)= 60 (slove for k)
2, 8(3a+)=9(2a-4) (solve for a)
i dont really pay attention and im failing. this is very forgein to me it just looks ike a cluster of numbers and signals. cn you step by step expail it please i will give a brainly!
Answer:
1. k=-9
2. a=-12
Step-by-step explanation:
1. -12(k+4)=60
use distributive property
-12k-48=60
add 48 to both sides
-12k=108
divide both sides by -12
k=-9
2. 8(3a)=9(2a-4)
use distributive property
24a=18a-36
subtract 18a on both sides
6a=-36
divide both sides by 6
a=-12

Francis mixes 3/8 gal of white paint, 2 7/8 gal of blue paint, and 1 1/4 gal of red paint.
How much white paint will Francis need to make 7 gallons of the same color paint?
Francis has made _____ gal of paint when he first mixes the three colors.
The constant of proportionality of white paint to gallons of mixed paint is ______
Francis will need __________ gal of white paint to mix together 7 gals of the same color paint.
PLEASE HELP!!!!!
Blank one the options are: thirteen-fourths, thirty-one eights, or nine-halves.
Blank two the options are: one-seventh, one-twelfth, three twenty-sixths, or thirty-six thirds
Blank three the options are one, eighty-four, seven twelfths, or twenty-one twenty-sixths
Please help me with the problem.
List all the info:
3/8 gallon of white paint
2 7/8 gallon of blue paint
11/4 gallon of red paint
First, let’s answer the first question.
Francis has made _____ gal of paint when he first mixes the three colors.
Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.
Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.
Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)

What is the value of s?
Explanation:
The two smaller angles add to the largest angle
46 + s = 75
s = 75-46
s = 29
Answer:
29
Step-by-step explanation:
75 is the whole angle and it gives you part of that angle (46). you subtract 75 - 46 to get s
Determine the relationship between the two triangles and whether or not they can be proven to be congruent.

Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?
25 Points for the correct answer
The domain and range for a function modeling the total amount of the investment, including interest are as follows;
Domain, X = {0<= years <= 10}Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + 10R)}The starting principal amount, P is $25,000.
Let the interest rate per year, be represented as, R (%)Time of investment, T = 10 yearsIn essence, after 10 years, the total amount Vladimir has is;
Total amount = 25,000( 1 + xR).In essence, the domain (No. of years ) is;

Step-by-step explanation:
4 gallons 1.80
2 gallons 0.90(half)
6 gallons 2.70(both above)
Answer:
$2.70
Step-by-step explanation:
Divide 1.80 by 4 = $45 Cents
( Check : 45 x 5 = 1.8) (* Add 0 )
So since it is now known that a gallon of low fat milks costs $45 cents per gallon, multiply 6 by 0.45 and you'll get 2.7
So it can be a type of currency,
add 0
So the reuslt would be $2.70
Therefore, the cost of 6 gallons of low fat milk is $2.70 ( 2 dollars and 70 cents).

Simplify your answer as much as possible.
Answer:
y = -4
Step-by-step explanation:
-8y+6(y+5) = 38
-8y + 6y + 30 = 38
-2y + 30 = 38
-2y = 8
8 / -2 = -4
y = -4
Answer:
V= -4
Step-by-step explanation:
-8v+6(v+5) = 38
-8v+6v+30 = 38
-2v = 38-30
-2v = 8
v = 8/-2
v = -4
