2.5(12.75x + 24.50) = 188.75
1. Simplify both sides of the
equation
(remove parentheses
and/or combine like terms).
2. Use inverse operations and
properties of equality to
"undo" what is happening to
the variable. (use the
reverse order of operations
because we are undoing)
3. Check your answer by
substituting your answer
into the original equation.
Answers
Answer:
Step-by-step explanation:
First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.
Multiply 2.5 on each side of the equation like this:
(12.75 x 2.5) (24.50 x 2.5) =188.75
Once you're finished, you should get 61.25 and 31.875x =188.75
Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:
61.25 - 61.25 = 0
188.75 - 61.25 = 127.5
So now your equation should look like this:
31.875x = 127.5
You have to divide 31.875 by each side now.
Once you divide them, your final answer should be 4.
so x = 4.
I really hope this helps! ^^

Safety standards require a pool to add 3 chlorine tablets to every 2,000 gallons of water. Today, the lifeguards at Park Pool added 8 chlorine tablets to their pool's 10,000 gallons of water.
How does Park Pool's chlorine compare to the safety standards?
Choose 1 answer:
A
Park Pool has more chlorine than the safety standards require.
B
Park Pool has less chlorine than the safety standards require.
C
Park Pool has the right amount of chlorine.
Answers
Answer:
B
Step-by-step explanation:
The requirement is 3 chlorine tablets per every 2,000 galloons of water.
The lifeguards added 8 chlorine tablets for 10,000 galloons of water.
To get from 3 tablets to 8 tablets, we multiply by 8/3.
By multiplying 2,000 galloons of water by 8/3, we acquire approximately 5,333 galloons of water.
Since 5,333 is less than 10,000, the Park Pool has less chlorine than the safety standards require.
Hey there!
The correct answer is B
If they are supposed to add 3 for every 2000, that means they should have 6 for every 4000, and 9 for every 6000, and 12 for every 8000. This means they have less.

What is the answer to 2b + 8- 5b + 3 = -13 + 8b - 5
Answers
Answer:
2 8/11 = b
Step-by-step explanation:
2b + 8 - 5b + 3 = -13 + 8b - 5
combine like terms
11 - 3b = -18 + 8b
add 3b
11 = -18 + 11b
add 18
29 = 11b
divide by 11
2 8/11 = b
EXPLANATION : 2b-5b = -3b & 8+3 =11 , that’s leaves you with 3b+11=-13+8b-5 . do it to the other side . -13-5=-18 . leaves you with the equation -3b+11=-18+8b !!
move the variable to the left side & the constant to the right . which leads you to -3b-8b=-18-11 !! combine like terms & that takes you to -11b=-29 !! Divide both sides by -11 which makes B = 29/11 which is equivalent to 2 7/11. or 2.63

Yolanda’s bowling average for 2 games was 138. Her second game score was 8 points lower than her first game score. Which system of equations will determine Yolanda’s scores for her first game, f, and her second game, s?
Answers
Answer:
║⊕║Hello Wonderful Person║⊕║
This should be your answer:
So first let us solve 138 divided by 2. Which equals 69. So right now, each game Yolanda did was 69 points. But, it says her second game score was 8 points lower. But it still has to be 138 points. So, you take away 8 points from S-69 (second game) and add 8 to F-69(First game) Which will equal 61 for S and 77 for F. So the answer is,
Yolanda's first game (F) was 77 points.
Yolanda's second game (S) was 61 points.
In total she scored 138 points.
Step-by-step explanation:
I hope this helped!
(brainliest appreciated!)
First answer!! :DHave a wonderful and blessed day!Yolanda’s scores for her first game, f is 73, and her second game, s is 65
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Yolanda’s bowling average for 2 games was 138.
f+s=138....(1)
Her second game score was 8 points lower than her first game score.
s=f-8....(2)
Substitute 2 in 1.
f+f-8=138
2f-8=138
Add 8 on both sides
2f=138+8
2f=146
Divide both sides by 2
f=73
s=73-8
s=65
Hence, Yolanda’s scores for her first game, f is 73, and her second game, s is 65

A basketball has a mass of 1 kg and is traveling 12 m/s.
What would happen to the velocity if the momentum of the basketball were cut in half?
Answers
Answer:
[tex]6\:\mathrm{m/s}[/tex] (The velocity would also be halved)
Step-by-step explanation:
The momentum of an object is given as [tex]p=mv[/tex] where [tex]m[/tex] is the mass of the object and [tex]v[/tex] is the velocity of the object.
Because mass is constant, if the momentum ([tex]p[/tex]) was cut in half, the velocity of the basketball would also be halved:
Let [tex]p_1[/tex] be the initial momentum and [tex]p_2[/tex] be the final momentum:
[tex]\frac{1}{2}p_1=p_2,\\\frac{1}{2}mv_1=mv_2, \\\fbox{$\frac{1}{2}v_1=v_2$}[/tex]
Therefore, the basketball's new velocity is [tex]\frac{1}{2}\cdot 12=\fbox{$6\:\mathrm{m/s}$}[/tex].
