Part A
Select the correct choices to complete the sentence.
Jarvis bought 2 beach towels and 3 pairs of swim trunks at a retail store. Each beach towel costs $3 less than a pair of swim trunks. He spent a total of $79. Let s represent the cost of a pair of swim trunks.
Part B
Add the two expressions and set this sum equal to 79 to model the situation with an equation. Solve for s . What is the cost of one pair of swim trunks?
A) The equation that represents the cost of a pair of swim trunks is;
2(s - 3) + s = 79
B) The cost of a pair of swim trunks is; $28.33
How to solve Algebra Word Problems?Algebraic word problems are defined as questions that require translation of sentences to equations, and thereafter solving those equations.
Let the cost of one pair of swim trucks be s.
We are told that Each beach towel costs $3 less than a pair of swim trunks. Thus;
Cost of each beach trunk = (s - 3)
Jarvis bought 2 beach towels and 3 pairs of swim trunks at a retail store. Thus, we have;
2(s - 3) + s = 79
2s - 6 + s = 79
3s = 79 + 6
3s = 85
s = 85/3
s = $28.33

A recipe for a dozen iced cookies calls for 2 1/4 cups flour. Which can be used to determine the amount of flour needed to make 32 cookies?
Answer:
You can form a proportion to solve this problem.
Step-by-step explanation:
The proportion can look like this (there are other ways to write an equal proportion but this is just one of the ways you could go about it :)
[tex]\frac{2.25}{12}[/tex]=[tex]\frac{x}{32}[/tex]
12x=72
x=6 cups of flour

martha invested $41.25 into a company. if each share was worth $1 1/4 how many shares did Martha invest in the company
Answer: 33 shares
Step-by-step explanation:
Amount invested in the company = $41.25
Price per share = $1 1/4 = $1.25
To calculate the amount of shares that Martha invested in the company will be:
= Amount invested in the company/Price per share
= $41.25/$1.25
= 33 shares
Martha invested 33 shares in the company.

Given A(2, 3), B(8, 7), C(6, 1), which coordinate will make line AB perpendicular to line CD?
D(9, 3)
D(4, 4)
D(3, 3)
D(8, 4)
Answer:
The correct option is;
D(4, 4)
Step-by-step explanation:
The given coordinates of the points are, A(2, 3) B(8, 7), C(6, 1), therefore, the coordinates of the point D that will make CD perpendicular to AB will have a slope = -1/m, where, m = the slope of the line segment AB
The formula for finding the slope, m, of a segment, given the coordinates of two points on the straight line segment (x₁, y₁), (x₂, y₂)
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, for, the segment AB, we have;
m = (7 - 3)/(8 - 2) = 4/6 = 2/3
m = 2/3
Therefore, to make the segment AB perpendicular to the segment CD, the slope of the segment CD will be -1/m = -1/(2/3) = -3/2
The equation of the segment CD in point and slope form is therefore;
y - 1 = -3/2×(x - 6)
y - 1 = -3·x/2 + 9
The standard form of the equation of the segment CD is therefore;
y = -3·x/2 + 9 + 1 = -3·x/2 + 10
y = -3·x/2 + 10
The point that satisfies the above equation is the point (4, 4) because;
4 = -3 × 4/2 + 10
The correct option is therefore, D(4, 4).

2. Segment SW equals 8
Step-by-step explanation:
Setup the equation 6x+5=8x and then solve for x. x comes out to be 5/2. The substitute that in for x and solve. 6(5/2)+5 and this equals 20, your solution.
Segment SW=8 because of the perpendicular bisector theorem. It states that if a point lies on the perpendicular bisector of a segment, then it is equidistant from the endpoints of that segment (i.e., equal length). This makes Segment SW=8

For which values of x will the rational expression below be unidentified? (x-1)(x+1)/x+2
Answer:
C
Step-by-step explanation:
Given
[tex]\frac{(x-1)(x+1)}{x+2}[/tex]
The denominator of the rational function cannot be zero as this would make it undefined.
Equating the denominator to zero and solving gives the value that x cannot be, that is
x + 2 = 0 ⇒ x = - 2 ← excluded value
Answer:
C. -2
Step-by-step explanation:
Any number divided by 0 is undefined. So, find the value of x that will make the denominator(x + 2) equal to 0:
x + 2 = 0
Subtract 2 from both sides of the equation to find the value of x:
x = -2
The only value of x that could make the denominator 0 is x = -2.

0.00000012+8*10^-7 scientific notation
Answer:
9.2*10^-7
Step-by-step explanation:
Move decimal until there is one number to the left. The number of times moved will be the exponent. If the decimal moves left the exponent is positive, if it moves left it is negative.
So 0.00000012=1.2*10^-7
1.2*10^-7 + 8*10^-7
9.2*10^-7
