27. Isiah is 3 years younger than twice Jack's age. Kaleb is 4 times Isiah's age. Write a variable expression to represent Isiah's age and then another to represent Kaleb's age.
To represent Isiah's age, the variable expression is I = 2J - 3. To represent Kaleb's age, the variable expression is K = 4I.
Explanation:To write a variable expression for Isiah's age, we start by defining a variable. Let's call Isiah's age 'I'. We are given that Isiah is 3 years younger than twice Jack's age, which can be written as 2J - 3. So, the variable expression for Isiah's age is I = 2J - 3.
To write a variable expression for Kaleb's age, we know that Kaleb is 4 times Isiah's age. Therefore, Kaleb's age can be represented by the variable expression K = 4I, where 'K' represents Kaleb's age and 'I' represents Isiah's age.
Let Jack's age be represented by a variable, let's say j. To express Isiah's age in terms of Jack's age, we use the information given in the question. Isiah is 3 years younger than twice Jack's age, so we can write the expression for Isiah's age as 2j - 3. Following that, we can represent Kaleb's age as being 4 times Isiah's age, which can be expressed as 4(2j - 3).

A board is 85cm in length and must be cut so that one piece is 11cm longer than the other piece . Find the length of each piece. Round your answers to the nearest centimeter , if necessary.
What is the length of the smaller piece ?
What is the length of the larger piece ?
The shorter piece is 37 cm
The longer piece is 48 cm:
Step-by-step explanation:
Divide 85 cm by 2 = 42.5
Divide 11 cm by 2 = 5.5
Add them together = 48 cm
85 cm - 48 cm = 37 cm
Length of 1st piece = 37 cm
Length of 2nd piece = x + 11 = 37 + 11 = 48 cm
Now -
Length of smaller piece = 37 cm
Length of larger piece = 48 cm
We have a board which is 85cm in length and must be cut so that one piece is 11cm longer than the other piece.
We have to find the length of each piece, length of the smaller piece, length of the larger piece.
The sum of three numbers such that the next number is 'n' times more than the previous number is 99. Express 'n' as a function of the very first number (say x).Now -
x + (x + n) + (x + 2n) = 100
3x + 3n = 99
x + n = 33
n = 33 - x
According to the question, we have -
Length of board = 85cm.
Assume that the length of first piece be x. Then -
x + ( x + 11 ) = 85
2x + 11 = 85
2x = 74
x = 37
Hence -
Length of 1st piece = 37 cm
Length of 2nd piece = x + 11 = 37 + 11 = 48 cm
Now -
Length of smaller piece = 37 cm
Length of larger piece = 48 cm

Emily is itemizing deductions on her federal income tax return and had $5200
in medical expenses last year. If her AGI was $43,000, and if medical
expenses are deductible to the extent that they exceed 7.5% of a taxpayer's
AGI, how much can Emily deduct for medical expenses?
Answer:
Emily can deduct $1975 for medical expenses.
Step-by-step explanation:
Emily is itemizing deductions on her federal income tax return and had $5200. Her AGI was $43,000.
We have:
The AGI is =$43,000
Medical expenses amount = $5200
If medical expenses are deductible to the extent that they exceed 7.5% or 0.075 of a taxpayer’s AGI, means = 43,000 * 0.075 = $3225
Now the deductible amount is = $5200 - $3225 = $ 1975
Hence,Emily can deduct $1975 for medical expenses.
Answer:
Emily can deduct the $1,975 in medical expenses from her adjusted gross income.
Step-by-step explanation:
Before an individual could deduct medical expenses as long as they exceeded 7.5% of their adjusted gross income (currently it's 10%).
If Emily's AGI = $43,000, then she will be able to deduct medical expenses that exceed $3,225 (= $43,000 x 7.5%).
Emily's medical expense deductions = $5,200 - $3,225 = $1,975.
If this situation happened this year, Emily would have only been able to deduct $900 [= $5,200 - ($43,000 x 10%)]
A rectangle has a length of 30 cm and
height of 53 mm. What is the perimeter
of this rectangle in centimeters?
Final answer:
The perimeter of the rectangle is calculated using the formula P = 2l + 2w, converting the height from millimeters to centimeters and then applying the values to get a perimeter of 70.6 cm.
Explanation:
To calculate the perimeter of a rectangle, we use the formula P = 2l + 2w, where l is the length and w is the width of the rectangle. In this case, the rectangle's length is given as 30 cm, but the height (which can be considered as the width in the context of the perimeter) is given in millimeters. First, we need to convert the height to centimeters by dividing the number of millimeters by 10, because there are 10 millimeters in a centimeter. So, 53 mm is equivalent to 5.3 cm. Now, we apply the formula to find the perimeter:
P = 2 × 30 cm + 2 × 5.3 cm = 60 cm + 10.6 cm = 70.6 cm.
Therefore, the perimeter of the rectangle is 70.6 cm.

Acme Movers charges $175 plus $40 per hour to move household goods across town. Hank’s Movers charges $75 per hour. For what lengths of time does it cost less to hire Hank’s Movers?
Answer:
If the time is less than 5 hours cost less to hire Hank’s Movers
Step-by-step explanation:
Let
y -----> charge to move household goods across town.
x ----> number of hours
we know that
Acme Movers
y=40x+175 ------> equation A
Hank’s Movers
y=75x ------> equation B
Equate equation A and equation B
75x=40x+175
solve for x
75x-40x=175
35x=175
x=5 hours
For x=5 hours the charge is the same in both company
therefore
For x < 5 hours cost less to hire Hank’s Movers

Polly buys 14 cupcakes for a party. The bakery puts them into boxes that hold 4 cupcakes each.
a. How many boxes will be needed for Polly to bring all the cupcakes to the party? Explain how you know.
b. If the bakery completely fills as many boxes as possible, what fraction of the last box is empty? How many more cupcakes are needed to fill this box?
Answer:
Part a) The number of boxes needed will be 4
part b) The fraction of the box that is empty is [tex]\frac{1}{2}[/tex]
Part c) Are needed 2 cupcakes to fill the last box
Step-by-step explanation:
Part a) How many boxes will be needed for Polly to bring all the cupcakes to the party?
To find out the number of boxes needed, divide the total number of cupcakes by 4 (maximum number of cupcakes that fit in each box).
so
[tex]\frac{14}{4}=3.5\ box[/tex]
Round up
The number of boxes needed will be 4
Part b) If the bakery completely fills as many boxes as possible, what fraction of the last box is empty?
we know that
The maximum number of cupcakes per box is 4
The first three boxes have 4 cupcakes
The last box has
[tex]14-3(4)=2\ cupcakes[/tex]
The fraction of the box that is empty is equal to the number of cupcakes missing to fill the box divided by the cupcake capacity of the box
[tex]\frac{2}{4}=\frac{1}{2}[/tex]
Part c) How many more cupcakes are needed to fill this box
Subtract the number of cupcakes in the box from the cupcake capacity of the box
The last box has 2 cupcakes
The cupcake capacity of the box is 4
so
[tex]4-2=2\ cupcakes[/tex]
therefore
Are needed 2 cupcakes to fill the last box

7) Katie is baking muffins for a picnic. She can bake 24 muffins in 45 minutes. At this rate, how
many muffins can she bake in 90 minutes and how do you know?
Answer:
Katie can bake 48 muffins in 90 minutes.
Step-by-step explanation:
So, as you can see, it says she can bake 24 muffins in 45 mins. Some you make that a fraction:
24/45. The question asks how many muffins she can bake in 90 mins. So, next to the first fraction (proportion) write x/90.
Why x? Because you don't know how many muffins she made, so you'll use that to replace the number for now. X is the numerator because on the last proportion, you put the number of minutes as the denominator. X= how many muffins Katie baked.
So, you cross multiply. Multiply one numerator by the others denominator. Like this: 24×90 and 45×X. Write the answers under the denominator (Ex: 24 X
45 90
-----------
45x = 2160
Now, separate the variable (x) and the constant (45). To do something you must divide. Divide it by 45 to get x. Then, place your equal sign on the right side of that. Now, whatever you do to one side of the equal sign you must do to the other. So, divide 2160 by 45. If done coorectly, you should've gotten 48. X=48 muffins. Therefore, Katie baked 48 muffins.

Step-by-step explanation:
D. The value of x in terms of c is [tex]x=\frac{29}{8c}[/tex]
What is the value of x ?
The given equation is [tex]\frac{2}{3}(cx+ \frac{1}{2})-\frac{1}{4}=\frac{5}{2}[/tex]
Solving we get,
First we have to add 1/4 in both sides,
[tex]\frac{2}{3}(cx+ \frac{1}{2})-\frac{1}{4}+\frac{1}{4}=\frac{5}{2}+\frac{1}{4}[/tex]
⇒ [tex]\frac{2}{3}(cx+ \frac{1}{2})=\frac{5}{2}+\frac{1}{4}[/tex]
⇒ [tex]\frac{2}{3}(cx+ \frac{1}{2})=\frac{10+1}{4}[/tex]
⇒ [tex]\frac{2}{3}(cx+ \frac{1}{2})=\frac{11}{4}[/tex]
⇒ [tex](cx+ \frac{1}{2})=\frac{11}{4}*\frac{3}{2}[/tex]
⇒ [tex](cx+\frac{1}{2} )=\frac{33}{8}[/tex]
⇒ [tex]cx = \frac{33}{8} -\frac{1}{2}[/tex]
⇒ [tex]cx = \frac{33-4}{8}[/tex]
⇒ [tex]cx=\frac{29}{8}[/tex]
⇒ [tex]x=\frac{29}{8c}[/tex]
