3а - 10 = a + 20
How do you do this help please it will mean a lot
Answer:
a=15
Step-by-step explanation:
2a-10=20
2a=30
a=15
can i have one brainliest plz
Answer:
a = 15
Step-by-step explanation:
I assumed you were trying to solve for A :)
3a - 10 = a + 20
1. Combine like terms (A's on side, numbers on the other).
3a - 10 = a + 20
-a -a
-----------------------
2a - 10 = 20
+10 +10
------------------------
2a = 30
Now that all of your like terms are combined, work to isolate A. The only way to do this is to divide by 2 on both sides of the equal sign.
[tex]\frac{2a}{2} = \frac{30}{2}[/tex]
This leaves you with a = 15, which is your answer if you are told to solve for A
I hope this helps!

What value is equivalent to 3 x 12 / (4 + 2) ? Answer to work the problem is 6. Is that the value? I’m reading the expression as tho there should be a variable
Answer:
6
Step-by-step explanation:
3x12 = 36
(4+2) 6
simplify
36/6=6
The value is indeed 6 and there shouldn't be a variable because if there is, then there should be a variable in the question.
The simplified form of the expression (3 × 12)/(4 + 2) is 6.
What is PEMDAS rule?PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, An expression (3 × 12)/(4 + 2).
Now, 12×3 is 36, and (4 + 2) is 6.
Therefore the simplified form of the expression is,
= 36/6.
Now, we know that 6 times 6 is 36 so, 36 divided by 6 the quotient should be 6.
Therefore,
36/6.
= 6.
So, The value of the expression (3 × 12)/(4 + 2) is 6.

Solve 3/5 k - 5 = 7/10 k by eliminating the fraction. Explain how you determine what to multiply each term by and all the steps to solving the equation.
Answer:
k = -50
Step-by-step explanation:
3/5k - 5 = 7/10k
3*2 / 5 *2 = 6/10 to get a common denominator
6/10k - 5 = 7/10k subtract 6/10 from 7/10
-5 = 1/10k now eliminate fraction by multiple both sides by reciprocal (10/1)
-5(10) = 1/10(10)k
-50 = k

If a 18 25 fl oz bottles cost $144.00 how much does one bottle cost?
Answer:
One 25 fl oz bottle costs $8
Step-by-step explanation:
144÷18=8
Answer:
8$ if my math is correct.
Step-by-step explanation:
Kind of a trick question. It is asking how much each bottle costs. You know that there are 18 bottles and have a total cost of $144. You do not need the 25oz for this equation. Lastly, I divided the total cost by 18 to get the total of 8$ for each bottle

Anybody know this if you do plz help
Answer:
1. m = -3 b = 2
2. m = 1/2 b = -1
3. m = -1 b = 79
4. m = 2 b = -2
5. y = -4x + 3
Step-by-step explanation:
1. the equation y=mx + b is used in number 1. m = slope and b = y intercept. so, because -3 is in the m spot, it is the slope, and because 2 is in the b spot, it is the y intercept.
2. apply the same concept as number 1. 1/2 is in the m spot, so it is the slope, and -1 is in the b spot, so it is the y intercept
3. To know the slope of the graph, you do rise/run. meaning, from one point on the graph, count how many times you go down to get to the next points, and then how many times you go over to get to the point. So, the slope of this line is -2/2, which is equal to -1. So, m = -1. To get the y intercept, take a pair of points from the graph (for example, (3,76)) and take the slope, and fill those in to the y = mx + b equation, and then solve for b. so, you get 76 = -1(3) + b. then do -1 times 3 and get -3. add 3 to both sides and you get b = 79.
4. apply the same concept on number 4 as you did number 3. Find rise/run, and you get 2/1, so m = 2. then take a point from the line (like point (0,-2)) and and the slope and fill it in to y = mx + b. you get -2 = -2(0) + b. so, b = -2.
5. simply fill in the information into the y = mx + b equation. remember, m is the slope, and b is the y intercept. so, you get y = -4x + 3

A shirt is regularly priced at 42$. It is on sale for 15% off of the regular price. What is the sale price of the shirt ?
Answer:
$35.7
Step-by-step explanation:
you can convert 15% to a decimal by dividing by 100.
15/100 = .15
if you multiply the decimal by the cost of the shirt you get how much the discount is.
0.15 * $42 = 6.30
so a 15% discount on a $42 shirt is $6.30 off. So you subtract the discount from the total cost.
$42 - $6.30 = $35.70 that is the sale price of the shirt.
Answer:
$35.7
