giving brainliest
Answer:
187/6
Step-by-step explanation:
Simplify the following:
(7 + 1/4) 2^2 + (8 + 1/2 - 2)/3
2^2 = 4:
(7 + 1/4) 4 + (8 + 1/2 - 2)/3
Put 7 + 1/4 over the common denominator 4. 7 + 1/4 = (4×7)/4 + 1/4:
(4×7)/4 + 1/4 4 + (8 + 1/2 - 2)/3
4×7 = 28:
(28/4 + 1/4) 4 + (8 + 1/2 - 2)/3
28/4 + 1/4 = (28 + 1)/4:
(28 + 1)/4×4 + (8 + 1/2 - 2)/3
28 + 1 = 29:
29/4×4 + (8 + 1/2 - 2)/3
29/4×4 = (29×4)/4:
(29×4)/4 + (8 + 1/2 - 2)/3
(29×4)/4 = 4/4×29 = 29:
29 + (8 + 1/2 - 2)/3
Put 8 + 1/2 - 2 over the common denominator 2. 8 + 1/2 - 2 = (2×8)/2 + 1/2 + (2 (-2))/2:
29 + ((2×8)/2 + 1/2 + (2 (-2))/2)/3
2×8 = 16:
29 + (16/2 + 1/2 + (2 (-2))/2)/3
2 (-2) = -4:
29 + (16/2 + 1/2 + (-4)/2)/3
16/2 + 1/2 - 4/2 = (16 + 1 - 4)/2:
29 + ((16 + 1 - 4)/2)/3
16 + 1 = 17:
29 + ((17 - 4)/2)/3

13/2×1/3 = 13/(2×3):
29 + 13/(2×3)
2×3 = 6:
29 + 13/6
Put 29 + 13/6 over the common denominator 6. 29 + 13/6 = (6×29)/6 + 13/6:
(6×29)/6 + 13/6
6×29 = 174:
174/6 + 13/6
174/6 + 13/6 = (174 + 13)/6:

Answer: 187/6
Answer:
31 1/6
Step-by-step explanation:
7 1/4 × 2²+(8 1/2-2)÷3
Using PEMDAS
Parentheses first
7 1/4 × 2²+(6 1/2)÷3
Then exponents
7 1/4 × 4+(6 1/2)÷3
Changing the mixed numbers to improper fractions
7 1/4 = (4*7+1)/4 = 29/4 and ( 2*6+1)/3 = 13/2
29/4 × 4+(13/2)÷3
Multiply and divide from left to right
29 + 13/2÷3
Using copy dot flip
29 + 13/2 * 1/3
29 + 13/6
Changing back to a mixed number
13/6 = 12/6 + 1/6 = 2 1/6
29 + 2 1/6
Add
31 1/6
Is x=-4 a solution to the equation —3z + 10 = 5?
Answer:
No.
Step-by-step explanation:
First, note that there is no variable x inside the equation. Therefore, there is nothing for the -4 to plug into.
However, if you meant to put the same variable, it still will not work.
Plugging in -4 for z (if you meant z = -4), would give you the following:
Assuming that z = -4
-3(-4) + 10 = 5
-12 + 10 = 5
-2 ≠ 5.
Therefore, even if you did mean to put the same variable, it will still not be correct.
~
For the given equation, there is no variable x but z is a variable in the linear equation. Since x is not a variable of the equation, we can't put the value given.
But if we plug the value of -4 in place of z:
➝ -3(-4) + 10
➝ 12 + 10
➝ 22 which is not equals to 5.
Hence, this equation is not satisfying for the value of variable given that is 4. Thus, -4 is not a solution to the given equation[tex].[/tex]

Select all the ratio that are equivalent to 8:6.
A. 4:3
B. 6:8
C. 16:12
D. 10:8
E. 7:5
4:3 and 16:12
4 times 2 is 8
3 times two is 6 therefore
4:3 has the same value
same with the second except it is 8 and 6 times 2
Answer: A and C
Step-by-step explanation: If you take the ratio and divide both sides by 2, you get the equivalent ratio 4:3. Then if you take the ratio and multiple both sides by 2, you will get the equivalent ratio 16:12. This means that both A and C are equivalent to the ratio 8:6.

Step-by-step explanation:
A professional baseball player earned $1,715,000 from
playing baseball last year.
An autobiography he had written last year sold 300,000
copies at a price of $24 each. He received 10% in
royalties on the book sales.
What was his total salary last year?
$
Answer:
The right answer is actually $2,435,000.00
Step-by-step explanation:
The reason is because you take 300,000 and times that by 24 then you get 7,200,000 then you take that and times it by 0.10 then you get 720,000 then you add that to the 1,715,000 and you get 2,435,000.
300,000 x 24 = 7,200,000
7,200,000 x 0.10 = 720,000
720,000 + 1,715,000 = 2,435,000
So, $2,435,000.00 is your answer.
The total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.
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.
It is given that:
A professional baseball player earned $1,715,000 from playing baseball last year.
The total earning from autobiography = 300,000x24
= 7,200,000
The royalty amount = 10% of 7,200,000
The royalty amount = 0.10x7,200,000
The royalty amount = 7,200,00
Total salary last year = 1,715,000 + 7,200,00
Total salary last year = $2,435,000
Thus, the total salary last year was $2,435,000 if a professional baseball player earned $1,715,000 from playing baseball last year.

23. A man and a woman share a prize of $1000 between them in the
ratio 1:4. The woman shares her part between herself, her mother
and her daughter in the ratio 2:1:1. How much does her daughter receive?
Number of parts = 1 + 4 = 5
Sum of all parts = $1000
Each part =
= 1000 ÷ 5
= $200
Money the man got =
= 200 × 1
= $200
Money the woman got =
= 200 × 4
= $800
The womans has $800 as her share .
Total parts = 2 + 1 + 1 = 4 parts
Sum of all parts = 800
Each part = 800 ÷ 4
Each part = 200
Then ,
The woman gets =
= 200 × 2
= $400
Her mother gets =
= 200 × 1
= $200
Her daughter gets =
= 200 × 1
= $200∴ Her daughter receives $200 .

Answer:
The answer would be B. Benefit would decrease by $7,020 annually
Step-by-step explanation:
One way you can find a percentage of any number is to take the percentage and move the decimals to the left twice, 13% into 0.13. With this decimal you would multiply it by the main number you want the percentage from, $54,000. 0.13 × 54,000 would give you a product of 7,020 thus your answer.
This isn't completely necessary but if you would like to check your answer you could do this process backwards, to do such you would take your answer you received, 7,020, and divide that by your main number, 54,000. The quotient would be your percentage as a decimal 7,020 ÷ 54,000 = 0.13. Thus meaning your answer is correct.

The points C, D, E and F all lie on the same line segment, in that order, such that the ratio of CD:DE:EFCD:DE:EF is equal to 3:2:1.3:2:1. If CF=42,CF=42, find DF.DF.
Answer:
2
Step-by-step explanation:
The required length of the DF on the line segment is 21 units.
Given that,
The points C, D, E, and F all lie on the same line segment, in that order, such that the ratio of CD:DE: EF is equal to 3:2:1, If CF=42,
To determine the length of the segment DF
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Total of the ratios
CF = 3x + 2x + 1x
CF = 6x
6x = 42
x = 7
Now,
DF = DE + DF
DF = 2x + 1x
DF = 2 * 7 + 7
DF = 14 + 7
DF = 21
Thus, the required length of the DF on the line segment is 21 units.

The number which is closest to the addition of two fraction numbers, 1/2 + 1/3 is 0.8.
What is the fraction number?A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,
[tex]\dfrac{a}{b}[/tex]
Here, (a) is the numerator and (b) is the denominator.
We have to find the addition of two fraction number 1/2 and 1/3. Suppose the value which is closest to 1/2 + 1/3 is n. Thus,
[tex]n=\dfrac{1}{2}+\dfrac{1}{3}\\[/tex]
Cross multiply to find the addition of two numbers,
[tex]n=\dfrac{3+2}{6}\\n=\dfrac{5}{6}\\n=0.833[/tex]
