Answer: a=4b/5
Step-by-step explanation:
To solve for a, we want to use algebraic properties to isolate a.
3a+2b=6b-2a [add both sides by 2a]
5a+2b=6b [subtract both sides by 2b]
5a=4b [divide both sides by 5]
a=4b/5
Now, we have found that a=4b/5.

Q.)A computer chooses a number between 1 and 1000. If the number is even how many outcomes are possible?
*I know the answer is 500 but I want to know how you get 500. *
Answer:
The answer is 500 because every other number is even. In other words, half of the numbers are even. Half of 1000 is 500.
Is that how you got the answer?

What is unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary Method
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
Kerry charges $25.50 per lawn to cut grass on Saturdays
and $28.50 per lawn to cut grass on Sundays.
If 4 lawns cuts in Saturday then the charges would be
=25. 50 x 4
=102
and, If 5 lawns cuts in Sunday then the charges would be
=28. 50 x 5
=142.5
Hence, the total she will earn 244.50.

Answer:
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex]
Step-by-step explanation:
By hit and trial method,
Given series of fractions will be,
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex]
Since, [tex]\frac{3}{6}=\frac{3\times 1}{3\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\frac{7}{14}=\frac{7\times 1}{7\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
[tex]\frac{29}{58}=\frac{29\times 1}{29\times 2}[/tex]
[tex]=\frac{1}{2}[/tex]
Therefore, [tex]\frac{1}{2}=\frac{1}{2}=\frac{1}{2}[/tex] is the reduced form of the fractions.
[tex]\frac{3}{6}=\frac{7}{14}=\frac{29}{58}[/tex] will be the answer.

19. What is the coordinate of the midpoint of the segment formed by the two points you found in Exercises 17 and 18?
Please explain
Answer:
0
Step-by-step explanation:
To find the coordinate of the midpoint of segment QB, first, find the distance from Q to B.
QB = |4 - 8| = |-4| = 4
The coordinate of the midpoint of QB would be at ½ the distance of QB (½*4 = 2).
Therefore, coordinate of the midpoint of QB = the coordinate of Q + 2 = 4 + 2 = 6
OR
Coordinate of B - 2 = 8 - 2 = 6
Coordinate of the midpoint of QB = 6
Coordinate of W = -8
Coordinate of A = 0
distance from W to A (WA) = |-8 - 0| = |-8| = 8
The coordinate of the midpoint of WA would be at ½ the distance of WA = ½*8 = 4.
Therefore, coordinate of the midpoint of WA = the coordinate of W + 4 = -8 + 4 = -4
Or
Coordinate of A - 4 = 0 - 4 = -4
Coordinate of the midpoint of WA = -4
Now, let's find the midpoint between the two new coordinates we have found, which are -4 and 4
Distance of the segment formed by coordinate -4 and 4 = |-4 - 4| = |-8| = 8
Midpoint = ½*8 = 4
Coordinate of the midpoint = -4 + 4 = 0
Or
4 - 4 = 0

In a bag there are 3 red marbles, 2 yellow marbles, and 1 blue marble. What are the odds of a yellow marble being selected on the first draw? CHOICES ------> ( 4:2 1:5. 3:3. 2:4) SOS
Answer:
1:3
Step-by-step explanation:
To find the probability of selecting a certain type of item from a collection, simply divide the number of items of that type by the total number of items.
There are 3 + 2 + 1 = 6 marbles in total. There are 2 yellow marbles, so the probability of choosing a yellow marble on the first draw is 2/6. This can be further simplified to 1:3.
Answer:
i would say 2:4
Step-by-step explanation:
think about them as basketball teams
The yellow team has two players
the mix team has 4 players
so the game is 2 players on 4 players
Find the inverse of the following function g(x) = 2x+10/4
Answer:
Step-by-step explanation:
To find the inverse of the function you need to swap x and y
g(x)=y so therefore if you switch x and y, you get
x= 2y+ 10/4
Next, you need to get all of the values on the y side over to the x side. To do this you need to subtract 10/4 from the y side of the equation.
x-10/4=2y+10/4-10/4
The end product of this should be... (This is not your answer)
x-10/4=2y
Now you need to get rid of the 2 on the y side. To do this you need to divide both sides of the equation by 2
2/x-10/4=2y/2
So your answer is...
x-10/4 over 2 = y
OR
2/x + 5/4 = y

Two times the complement of an angle is 23 less than the supplementary of the angle. What is the measure of the angle?
Answer:
Step-by-step explanation:
Let the angles be x and y
If the two angles are complementary then their sum is 90 i.e x+y = 90
x = 90-y
If the two angles are supplementary, then their sum is 180 i.e x+y = 180
x = 180-y
If two times the complement of an angle is 23 less than the supplementary of the angle, this is written as;
2(90-y) = (180-y)-23
180-2y = 157-y
-2y+y = 157-180
-y = -23
y = 23
Hence the angle is 23°
Marrisa added 1.56 and 13.47. She got 29.07. What mistake could Marrisa have made? She forgot to move the decimal point to the left after she added. She lined up the front numbers instead of the decimal places. She lined up the last numbers instead of the decimal places. She didn’t carry correctly between place values.
without an explanation your answer is (B) She lined up the front numbers instead of the decimal places.
if you need an explanation here:
________________________________________
For a problem with a decimal in the numbers, you ALWAYS have to line them up or your answer will be incorrect.
She should have put: 13.47
+ 1.56
15.03
therefore, 15.03 would have been her correct answer. :-)

Expand the terms in the bracket
That's
[tex]6x + x + 2 > 12 \\ 7x + 2 > 12[/tex]
Subtract 2 from both sides of the inequality
That's
[tex]7x + 2 - 2 > 12 - 2 \\ 7x > 10[/tex]
Divide both sides by 7
That's
[tex] \frac{7x}{7} > \frac{10}{7} [/tex]
We have the final answer as
