The total cost of a sweater and a pair of pants was $89.47. If the price of the sweater was $8.53 less than the pair of pants, what was the price of the sweater? Express your answer as a simplified fraction or a decimal rounded to two places.
Answer:
Let S = price of sweater
Let P = price of pants
S + P = 89.47 because that was the total spent
S = P - 8.53 because the sweater is 8.53 less than pants
Substitute P-8.53 in place of S in the
1st equation and solve for P
P - 8.53 + P = 89.47
2P - 8.53 = 89.47 add 8.53 to both sides
2P = 89.47 + 8.53
2P = 98.00 divide both sides by 2
P = 98.00/2
P = $49.00
S = P - 8.53
S = 49.00-8.53
S = $40.47
A sweater costs $40.47 and the pants cost $49.00
Lisa works at a music store. Last week she sold 6 more than 3 times the number of CDs that she sold this
week. Lisa sold a total of 110 CDs over the two weeks. Find the number of CDs she sold last week and the
number of CDs she sold this week.
Answer:
This week sales = 26
Last week sales = 84
Step-by-step explanation:
Let this week sales = x
Sales last week = 6 + 3x
Sales last week + this week = 110
x + (6 + 3x) = 110
x + 6 + 3x = 110
6 + 4x = 110
4x = 110 - 6
4x = 104
x = 26
This week sales = 26
Last week sales = 6 + 3(26) = 84

Write and solve a inequality to represent the situation:
Answer:
5 people
Step-by-step explanation:
1. I subtract 5.10 from 45 which gave me 39.90
2. I divided 39.90 by 7 to figure out how many people he could buy for
3. I had gotten 5.7 so I had to round
4 final answer is 5
Answer:

PQRS is a parallelogram. Solve for x.
Plz help
Answer:
The opposite sides of a parallelogram are congruent, then
19x - 9 = 13x + 15 ( subtract 13x from both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4

Consecutive angles are supplementary, sum to 180° , that is
10y - 37 + 4y + 7 = 180
14y - 30 = 180 ( add 30 to both sides )
14y = 210 ( divide both sides by 14 )
y = 15
Then
∠ R = 10y - 37 = 10(15) - 37 = 150 - 37 = 113°
Then
∠ P = 113° ( opposite angles are congruent )

Dvide if the polynomial does not divide evenly. Include the remainder as a fraction (18u^2 - 142u - 11) ÷ (u - 8)
Answer:
18u + 2 + 5/(u - 8)Step-by-step explanation:
(18u^2 - 142u - 11) ÷ (u - 8) 18u^2 - 142u - 11 = 18u^2 - 8*18u + 2u - 11 = 18u(u - 8) + 2u - 16 + 5 =18u(u - 8) + 2(u - 8) + 5 =(18u + 2)(u - 8) + 5(18u^2 - 142u - 11) ÷ (u - 8) = 18u + 2 + 5/(u - 8)Answer:
18u + 2 + 5/u - 8.
Step-by-step explanation:
(18u^2 - 142u - 11) ÷ (u - 8)
= 18u + 2 + 5/u - 8.

Are the fractions 3/8 and 9/27 equivalent? If yes, explain how you know they are equivalent. If they are not equivalent, what is a fraction that would be equivalent to 3/8.
Answer:
Step-by-step explanation:
The factors are 9 and 27 are 1,3,9,27
With that, 9/27 is undoubtedly reducible to 1/3
Before now,we were told that when a number divides itself,the result is zero...now,⅜÷⅓ should give us 1 but 3/8×3/1 = 9/8 and 9/8≠1 hence,they aren't same!

Answer:
[tex]1 \frac{36}{84} [/tex]
simplified :
[tex]1 \frac{3}{7} [/tex]
Step-by-step explanation:
first, we turn them into improper fractions
[tex]3 \frac{ + 3}{ \times 4} \div 2 \frac{ + 5}{ \times 8} [/tex]
First, we multiply 3×4=12+3=15 the demoninator will remain the same.
2×8=16+5=21, denominator remains the same.
[tex] \frac{15}{4} \div \frac{21}{8} [/tex]
when it comes to division with fractions, you flip the right(direction)fraction then multiply.
[tex] \frac{15}{4} \times \frac{8}{21} [/tex]
15×8=120
4×21=84
[tex] \frac{120}{84} [/tex]
then turn in back into a mixed fraction.
[tex]1 \frac{36}{84} [/tex]
demoninator remains the same, how many times 84 goes into 120, which is once(whole number) and how many is left over (numberator)
A teacher is assessing the correlation between the number of hours spent studying and the average score on a science test. The table shows the data:
Number of hours spent studying
()
0
0.5 1 1.5 2 2.5 3 3.5 4
Seore on science test
V)
57 62 67 72 77 82 87 99 97
Part A: Is there any correlation between the number of hours students spent studying and the score on the science test? Justify your answer
Answer:
A.)
the correlation between the number of hours students spent studying and the score on the science test seems to be that the people who spent more time studying got a better score than the people who didn't/ did less.
B.)
y = a - b ^x
a = 57
b = 5
because every .5 hours adds 5 points to the score
y = 57 (5) ^x
and as a function
F(x)= 57(5)
C.)
slope: 10
y / x
5 / 0.5
= 10
y-intercept: 57
x is 0 and y is 57 that is the y-intercept
it has a positive slope.
This week at the farmer's market the price of oranges per pound has decreased by 20% compared to last week. If the price of oranges this week is $3.89, which equation would represent the price of oranges per pound last week, p?
Answer:
$4.8625
Step-by-step explanation:
$3.89 + 20%
$3.89 = 80%
$3.89 × ¼ = $0.9725
$0.9725 × 5 = $4.8625
