Answer:
x^2 - 4/5x - 3/5 = 0
Step-by-step explanation:
5x^2/5 - 4x/5 - 3/5 = 0/5
x^2 - 4/5x - 3/5 = 0
[tex]\\ \sf\longmapsto \dfrac{5x^2-4x-3=0}{5}[/tex]
Divide each variable by 5[tex]\\ \sf\longmapsto \dfrac{5x^2}{5}-\dfrac{4x}{5}-\dfrac{3}{5}=\dfrac{0}{5}[/tex]
[tex]\\ \sf\longmapsto x^2-\dfrac{4}{5}x-\dfrac{3}{5}=0[/tex]

-2y + 6 = -12
what is the answer??
Answer:
9
Step-by-step explanation:
Simplifying
2y + -6 = 12
Reorder the terms:
-6 + 2y = 12
Solving
-6 + 2y = 12
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 2y = 12 + 6
Combine like terms: -6 + 6 = 0
0 + 2y = 12 + 6
2y = 12 + 6
Combine like terms: 12 + 6 = 18
2y = 18
Divide each side by '2'.
y = 9
Simplifying
y = 9
Answer:
Y=9
Step-by-step explanation:
Subtract 6 from both sides. Simplify. Dive both sides of the equation by the same term. Simplify. Solution y=9
What would you do to both sides of the equation to solve for x?

50% means 1/2 of something.
So...
1/2 of 50 is 25.
-kiniwih426
Answer:
$50
Step-by-step explanation:
Solution:
Let the unknown number be x
50% × x = $25
50/100 × x = 25
x = 25×100/50
x = $50
Varification:
50% of $50 is $25
50/100 × 50 = 25
25 = 25

A 16-ounce of shampoo cost $4.69. What is the price per ounce, rounded to the nearest cent
Answer:
A, 0.29
Step-by-step explanation:
Since 16 ounces cost 4.69, 1 ounce costs 4.69 divided by 16. This is roughly 0.29, which would then be A.
4. Susannah is drawing a card from a standard 52-card deck. A standard deck of cards
contains four suits -- diamond, club, spade & heart. Each suit has 13 cards. Face cards (12)
are Jack, Queen, and King cards.
a. What is the probability that the card she draws is a diamond?
b. What is the probability that the card she draws is a face card?
c. What is the probability that the card she draws is a face card and a diamond?
d. What is the probability that the card she draws is a face card or a diamond?
Answer:
1/4(25%), 3/13(23%), 3/52(6%), 11/26(42%)
Step-by-step explanation:
a. 4 suits, therefore the probability is 1/4
b. there are 12 face cards. therefore the probability is 12/52 which simplifies to 3/13
c. there are only 3 cards that are diamonds and face cards. Therefore, it is 3/52
d. there are 12 face cards and 13 cards of each suit. But there are 3 that overlap. therefore, there are 22 in total, so 22/52. it simplifies to 11/26.
A shipment of sugar fills
4/9 containers. If each container holds 2 2/5
tons of sugar, what is the amount of sugar in the entire shipment?
Write your answer as a mixed number in simplest form.
Answer:
For this problem, multiply these fractions.
First, make each one an improper fraction: 2 4/5 is the same as 14/5 and 2 3/7 is the same as 17/7.
Now, 14/5 times 17/7 yields 238/35 which reduces to 34/5. This may be expressed also as the mixed fraction 6 4/5.
So, the shipment contains 6 4/5 tons of sugar. (This is also equal to 13,600 pounds of sugar.)

Find the change below as a percentage. Then choose whether it is a percent of increase or a percent of decrease.
Change from 32 miles to 24 miles.
х
G
Percentage change: 196
This is a percent of increase.
This is a percent of decrease.
Need help with this question?
Answer:
increase
Step-by-step explanation:
the change from 32 miles to 24 is decrease is 8 difference. % change to 196 is an increase.
The percentage change is 25% and it is a percent of increase.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
To find the percentage change from 32 miles to 24 miles, we first need to calculate the absolute change:
Absolute change = Old value - New value
Absolute change = 32 miles - 24miles
Absolute change = 8 miles
Percentage change = (Absolute change / Old value) x 100%
Percentage change = (8 miles / 32 miles) x 100%
Percentage change = 25%
Which means there is a 25% increase from 32 miles to 24 miles.
Therefore, the percentage change is 25% and it is a percent of increase.

A, B and C lie on a straight line segment.A, E and D lie on a straight line segment.BE = 1.8m, CD = 9m and BC = 1.7m.Work out the length of AB.Write your answer to two decimal places.
The relationship between the points is an illustration of similar shapes.
The length of AB is 0.43
The given parameters are:
[tex]\mathbf{BE = 1.8}[/tex]
[tex]\mathbf{CD = 9}[/tex]
[tex]\mathbf{BC = 1.7}[/tex]
From the question (see attachment), we have the following observations:
BE corresponds to CDAB corresponds to ACSo, the equivalent ratio is:
[tex]\mathbf{AB:BE =AC:CD }[/tex]
Substitute known values
[tex]\mathbf{AB:1.8 =AC:9 }[/tex]
Express as fractions
[tex]\mathbf{\frac{AB}{1.8} =\frac{AC}{9} }[/tex]
Multiply both sides by 1.8
[tex]\mathbf{AB =\frac{AC}{5} }[/tex]
AC = AB + BC
So, we have:
[tex]\mathbf{AB =\frac{AB + BC}{5} }[/tex]
Substitute 1.7 for BC
[tex]\mathbf{AB =\frac{AB + 1.7}{5} }[/tex]
Multiply through by 5
[tex]\mathbf{5AB =AB + 1.7}[/tex]
Collect like terms
[tex]\mathbf{5AB -AB =1.7}[/tex]
[tex]\mathbf{4AB =1.7}[/tex]
Divide both sides by 4
[tex]\mathbf{AB=0.425}[/tex]
Approximate
[tex]\mathbf{AB=0.43}[/tex]
Hence, the length of AB is 0.43

Robert spends $30.45 before tax at the bookstore. If the sales tax rate in his city is 7.25%, what is the total cost of his purchase?
Answer:
32.65
Step-by-step explanation:
Answer:
Total cost of purchase = $32.66
Step-by-step explanation:
$30.45 before tax
If sales tax = 7.25% or 0.0725, then: $30.45 × 0.0725 = $2.21
Add the sales tax of $2.21 to $30.45 = $32.657 or $32.66
Therefore, the total cost of his purchase is $32.66
