What is the value of 2(-8) (- 5) + 12
mandle is making 15 cups of fruit salad . what ration of grapes to blueberries should she use?
Answer:
12:3
Step-by-step explanation:
The first thing you should do for this case is to graph the data you have in the statement to see the relationship between grapes and blueberries.
The function represented by the table is
y = 0.25x
Then, as Mandie is making 15 glasses of fruit salad, we have:
y + x = 15
We have two equations and two unknowns that we must solve.
y = 0.25x
y + x = 15
Resolving
For x:
0.25x + x = 15
1.25x = 15
x = 15 / 1.25 = 12
For y:
y = 0.25x = 0.25 (12) = 3
Answer
The ratio of grapes to blueberries she should use is 12: 3

The sum of ages of 3 siblings, Alice, Bruce and Chuck is 27. The sum of ages of Alice and Bruce is 14 and the sum of ages of Bruce and Chuck is 22. Find each sibling's age by using system of linear equations.
Answer:
Alice = 5
Bruce = 9
Chuck = 13
Step-by-step explanation:
alice= x
Bruce = y
Chuck = z
x+y+z= 27
x+y= 14
therefore z= 27-14= 13
Chuck = 13
y+13 (z) = 22
therefore y = 22-13= 9
Bruce = 9
9+13= 22
therefore x= 27 - 22= 5
Alice = 5
confirmation
5 + 9 + 13 = 27
5+9= 14
9 + 13 = 22
Each sibling's age i..e Alice be 5 years, Bruce be 9 years, and Chuck be 3 years.
Given that,
The sum of ages of 3 siblings, Alice, Bruce, and Chuck is 27. The sum of ages of Alice and Bruce is 14 and the sum of ages of Bruce and Chuck is 22.Here we assume Alice be x, Bruce be y, and Chuck be z.Based on the above information, the calculation is as follows:
x + y + z = 27
x + y = 14
So,
z = 27 - 14
= 13
i.e. Chuck = 13
Now
y + 13 (z) = 22
So,
y = 22 - 13
= 9
i.e. Bruce = 9
Now
9+13= 22
So,
x = 27 - 22
= 5
i.e. Alice = 5
Therefore we can conclude that each sibling's age i..e Alice be 5 years, Bruce be 9 years, and Chuck be 3 years.

Your checking account has a beginning balance of $68.02. You deposited $169.23 into the account. The next week you spent $31.57
for gas and $25 to go out with friends. How much do you have left in the account?
S212.25
S205.68
$237.25
$180.68
Answer:
180.68
Step-by-step explanation:
D) $180.68
At the beginning you have 68.02 plus the 169.23 deposit which makes a new total of 237.25.Then you spend 31.57 so the new equation is (237.25-31.57)
which is 205.68 then you spend another 25 for gas (205.68-25=180.68)
So your answer is $180.68

what is The expression 12+9g-30h factored using the GCF is and btw I already tryed 3
Hello!
Answer:
3(4+3g-10h)
Step-by-step explanation:
Hope this helps!
The GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)
what is GCF?A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common.
For example, 12, 20, and 24 have two common factors: 2 and 4.
The largest is 4, so we say that the GCF of 12, 20, and 24 is 4.
Given:
12+9g-30h
Now, to find the GCF we have to factorize the numbers
12= 2 x 2 x3
9 = 3 x 3
30= 2x 3 x 5
So, the Greatest common factor is 3.
Thus, the GCF expression is 12+9g-30h is 3(4 + 3g - 10 h)

If the student has already read 2525 of the pages, how long will it take them to read the rest of the book? _____ minutes Your answer should be written as a decimal rounded to the nearest tenth if necessary.
The number of pages the student can read in a minute is an illustration of rates.
The time left to complete the whole book is 90 minutes
From the complete question, the student's rate is:
[tex]\mathbf{Rate = 50\ pages/hr}[/tex]
The number of pages is:
[tex]\mathbf{Total = 100\ pages}[/tex]
First, we calculate the time to read the whole book
[tex]\mathbf{Total\ Time = \frac{Total\ pages}{Rate}}[/tex]
[tex]\mathbf{Total\ Time = \frac{100\ pages}{50\ pages/ hr}}[/tex]
[tex]\mathbf{Total\ Time = 2\ hours}[/tex]
The number of the student has read is:
[tex]\mathbf{Pages = 25}[/tex]
Next, we calculate the time spent on the 25 pages
[tex]\mathbf{Time\ Spent = \frac{Pages}{Rate}}[/tex]
[tex]\mathbf{Time\ Spent = \frac{25\ pages}{50\ pages/hr}}[/tex]
[tex]\mathbf{Time\ Spent = 0.5\ hr}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Spent = 30\ minutes}[/tex]
So, the time left is:
[tex]\mathbf{Time\ Left = Total\ Time - Time\ Spent}[/tex]
This gives
[tex]\mathbf{Time\ Left = 2\ hours- 30\ minutes}[/tex]
[tex]\mathbf{Time\ Left = 1\ hour, 30\ minutes}[/tex]
Convert to minutes
[tex]\mathbf{Time\ Left = 90\ minutes}[/tex]
Hence, the time left is 90 minutes

input the correct Anwser as OS For One Solution, NS for no solution and INF for infinite
Answer:o
Step-by-step explanation:o
Answer:
1) INF
2) NS
Because:
1 is INF because both sides of the equation are the same
x can be replaced with any number therefor, there are infinite solutions.
2 is NS because you are left with 12=2 so there would not be a solution.

Leila puts an integer into the "In" box of each machine.
She finds that the answer that appears in the "Out" box of Machine A is the same as the
answer that appears in the "Out" box of Machine B.
What was the answer produced by both machines?
Show how you figured it out
The machines represent equivalent expressions.
The output produced by both machines is 372
The equation represented on machine A is:
[tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
The equation represented on machine B is:
[tex]\mathbf{y = 4(2(x + 11) - 7)}[/tex]
Where: x and y represent the inputs and the outputs, respectively
When the outputs are the same, it means:
[tex]\mathbf{y = y}[/tex]
So, we have:
[tex]\mathbf{2(5x + 3) - 24 = 4(2(x + 11) - 7)}[/tex]
Open brackets
[tex]\mathbf{10x + 6 - 24 = 8x + 88 - 28}[/tex]
[tex]\mathbf{10x - 18 = 8x + 60}[/tex]
Collect like terms
[tex]\mathbf{10x - 8x = 18 + 60}[/tex]
[tex]\mathbf{2x = 78 }[/tex]
Divide both sides by 2
[tex]\mathbf{x = 39 }[/tex]
Substitute 39 for x in [tex]\mathbf{y = 2(5x + 3) - 24}[/tex]
[tex]\mathbf{y = 2 \times (5 \times 39 + 3) - 24}[/tex]
[tex]\mathbf{y = 372}[/tex]
Hence, the output produced by both machines is 372
