Step-by-step explanation:
a. how old is Cheryl?
Cheryl's age = d + 5
b. how old is Brandon?
d + 5 + 2
= d + 7
c. what was the difference in their ages 5 years ago?
Cheryl age five years ago = d
Brandon's age five years ago = d + 2
Difference = d + 2 - d = 2 years
d. what is the sum of their ages now?
Cheryl's age = d + 5
Brandon age = d + 7
Sum = d + 5 + d + 7
= 2d + 12
e. what will the sum of their ages be two years from now?
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Sum = d + 7 + d + 9
= 2d + 16
f. what will the difference of their ages be two years from now
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Difference = Brandon age - Cheryl age
= (d + 9) - (d + 7)
= 2 years.

A triangle with side lengths of 3, 4, and 5 units is classified as
In the triangles, Line segment G K is-congruent-to line segment P N and Line segment G H is-congruent-to line segment M P.
Triangles G H K and P M N are shown. The length of side H K is 32 centimeters. The length of side M N is 40 centimeters. The lengths of sides H G and M P are congruent. The lengths of sides G K and P N are congruent.
Which statement correctly compares the angles?
Angle G is congruent to angle P.
Angle G is smaller than angle P.
Angle G is larger than angle P.
Angle G is congruent to angle N.
Answer:
B). Angle G is smaller than Angle P
Step-by-step explanation:
Given that,
GK ≅ PN,
GH ≅ MP
HK = 32 cm
MN = 40cm
and the other lengths are congruent.
This suggests that although the triangles are congruent yet they are not similar. Hence, the second statement correctly compares the angles that 'angle P is greater than angle G.'

Variable:
-
Equation:
Solution:
Answer:
Variable- it doesnt really matter. Im just going to use X.
Equation- $16.35 + x = $39.75.
The solution is $23.40
Step-by-step explanation: Basically you reverse the equation so it says $39.75 - $16.35 = x . Then you just subtract.
Answer:
$23.40
Step-by-step explanation:
To find how much she spent on the bracelet, subtract how much she spent on the pair of sunglasses from her total amount
$39.75- $16.35=$23.40
Amelia is deciding between two landscaping companies for her place of business.
Company A charges $35 per hour and a $250 equipment fee. Company B charges $25
per hour and a $300 equipment fee. Let A represent the amount Company A would
charge for t hours of landscaping, and let B represent the amount Company B would
charge for t hours of landscaping. Write an equation for each situation, in terms oft,
and determine which company would be cheaper if Amelia needs 7 hours of
landscaping.
Answer: B is Cheaper
Step-by-step explanation: Pic is attached. It is the initial price plus the money they charge per hour, multiplied by hour. From there it is just plugging in 7 for the hour. Hope this helps!
Company B would be cheaper than Company A for 7 hours of landscaping.
What is an equation?Two or more expressions with an equal sign are defined as an equation.
Given that, Company charges $35 per hour and a $250 equipment fee while Company B charges $25 per hour and a $300 equipment fee.
The amount charged by Company A for t hours of landscaping is:
A = 35t + 250 (1)
Similarly, the amount charged by Company B for t hours of landscaping is:
B = 25t + 300 (2)
Now, solve equation (1) for t = 7:
A = 35 (7) + 250
A = 245 + 250
A = 495
Hence, company A would charge $495 for 7 hours of landscaping.
Similarly, solving equation (2) for t = 7:
B = 25(7) + 300
B = 175 + 300
B = 475
Hence, company B would charge $475 for 7 hours of landscaping.
Therefore, Company B would be cheaper than Company A for 7 hours of landscaping.

The lengths of the sides of a triangle are in the extended ratio 4:7:10. The perimeter of the triangle is 105 cm. What are the lengths of the sides?
The lengths of the sides of the triangle in cm are
Answer:
20cm, 28cm, 40cm
Step-by-step explanation:
Let the shortest side be 4x, the middle side be 7x and the longest side be 10x.
4x + 7x + 10x = 105
21x = 105
x = 105 ÷ 21
x = 5
Shortest side (4x) = 5 × 4
Shortest side (4x) = 20
Middle side (7x) = 7 × 4
Middle side (7x) = 28
Longest side (10x) = 10 × 4
Longest side (10x) = 40

10. The total cost of a candy bar and a bag of chips is $1.70. If the cost of a candy bar and 2 bags of chips is
$2.45, what is the cost of a candy bar?
Answer: maybe 75 cents
Step-by-step explanation:
Answer:
The cost of a candy bar is $0.75.
Step-by-step explanation:
With the provided first sentence preceded along the lines, 'total cost of a candy bar and a bag of chips is $1.70.'
--Intially, determine the quotient of 1.70 and the two quantities.
+ Result should be 0.85
Thus symbolizing .85 is the valid price of a candy bar and a bag of chips.
------------------------- Although, we are not done. -----------------------------------
Let's take the second sentence into account.
"If the cost of a candy bar and 2 bags of chips is $2.45, what is the cost of a candy bar?"
Determine the sum of .75 and (.85*2)
Alert: .75 came from subtracting 10 from the intial .85
Thus the sum is $2.45, which was stated earlier as the cost of a candy bar and 2 bags of chips.

56 32 48 52 51 53 48 38 35 42 40 46 54 50
In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.
42 43 47 48 51 52 56 56 58 60 62 64 65 66
Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64
+ 65 + 66) ÷ 14
Mean of the data = 770 ÷ 14
Mean of the data = 55
Median = (56 + 56) ÷ 2
Median = 112 ÷ 2
Median = 56
Lowest value = 42
Highest value = 66
Range = Highest value - Highest value
Range = 66 - 42
Range = 24
Lower Quartile = 25% of the data
Lower Quartile = 48
Upper Quartile = 75% of the data
Upper Quartile = 62

How much total tax will a customer pay on both?
Answer the questions to show how to write and simplify expressions that represent the problem.
Answer:
The total amount that the consumer had to pay for both products was $ 94.50.
Step-by-step explanation:
Given that Mal sold a large photo for $ 50 and a large frame for $ 40, and that the sales tax for these products is 5%, to determine the total amount that the consumer had to pay to purchase these products arises from the following calculation:
(50 + 40) x 1.05 = X
90 x 1.05 = X
94.5 = X
Therefore, the total amount that the consumer had to pay for both products was $ 94.50.
Answer:
1. Evaluate the expression: $4.50
