Answer: 4(5y−2)=40
Divide both sides by 4.
5y−2=
4
40
Divide 40 by 4 to get 10.
5y−2=10
Add 2 to both sides.
5y=10+2
Add 10 and 2 to get 12.
5y=12
Divide both sides by 5.
y= 12/5 or 2.4 please give brainliest

The answer is D. (-160)÷8
The answer can t be a decimal therefore a and c are out. The answer has to be negative bc it was a lost. Therefore since -160 was a loss it has to be negative
Answer:
D
Step-by-step explanation:
Loss = -160
Shared between 8 owners.
So, (-160) ÷ 8
Write 360 as a product of primes.
Use index notation when giving your answer
Answer:
First, find any number that divides evenly into 360. Perhaps the number that comes to mind, since it ends in a 0, is 10. Since 10 divides into 360 and the result is 36, you can write 360 = 10*36.

Answer:
2nd answer, and 5 hours
Step-by-step explanation:
Section 1
The answer is the 2nd one down. The tickets are selling at a rate of
floor tickets: 100/h; stand tickets: 75/h
Since the stand tickets were selling 150 in 2 hours, only 75 were sold per hour.
Section 2
There are only 375 stand tickets left to sell.
Every 2 hours 150 are sold or you can also say 75 per hour.
If you're selling 75 per hour, you would divide 375 by 75 which would give you 5 hours to sell out the stands tickets.
375/75 = 5 hours

He has a coupon for $10 off any grooming service. He must pay an 8% sales tax, which is applied to the discounted price, and then added to find the total price. Estimate the total amount Paul paid at the dog groomer.
Answer:
Well since you didn't provide the initial cost im just going to use 100$ as the initial cost.
the service costs 100 dollars minus the coupon of 10 dollars so 90 plus the sales taxes it is (which is 7.20$) it leaves us with a total of 97.20 saving him 10.80$ if he did not use the coupon

The length of the base of an isosceles triangle is x. The length of a leg is 5x – 3. The perimeter of the triangle is 60. Find x.
X
Answer: x = 6
Step-by-step explanation:
The perimeter of the isosceles triangle = 2 leg + base
Since the perimeter = 60
then 60 = 2(5x - 3) + x
60 = 10x - 6 + x
60 + 6 = 11x
6 = x
Find the difference (7-3t) - 5(-1.6t + 5)
Answer:
5t - 18
Step-by-step explanation:
STEP 1: Simplify 8/5
equation at end- 8 (7 - 3t) - (5 • ((0 - (— • t)) + 5)) 5
STEP 2: 2.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
5 5 • 5
5 = — = —————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
\2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-8t + 5 • 5 25 - 8t
——————————— = ———————
EQUATION AT END: (25 - 8t)
(7 - 3t) - (5 • —————————)
5
STEP 3: (7 - 3t) - (25 - 8t)

Point R is located at 8,13 where is R after a translation 8 units left and 6 units down
Answer:
On the Y axis
Step-by-step explanation:
Answer:
(0, 7)
Step-by-step explanation:
aight so its set up as (x,y). X on the graph is left and right while y is up and down. "8" means that the X is positive or to the right of the origin. If you go left, essentially you are subtracting. So 8-8=0. Same kind of idea for the Y axis. Up is positive, down is negative. If you're going down 6 from 13 (13-6) then you are at 7. (0,7)
solve for Y -2(y-3)+12y>16
Answer:
Y>1

Ruby is saving up to buy a new jacket. She already has $25 and can save an additional $7 per week using money from her after school job. How much total money would Ruby have after 10 weeks of saving? Also, write an expression that represents the amount of money Ruby would have saved in ww weeks.
Total savings after 10 weeks:
Total savings after ww weeks:
From the question;
1) Ruby will save $95 after ten weeks
2) The equation for ww weeks is; S = $25 + ($7 x ww)
What is an equation?
Total savings after 10 weeks:
Ruby saves $7 per week from her after school job, and she already has $25, so her total savings after 10 weeks can be calculated as follows:
Total savings = Initial savings + (Weekly savings x Number of weeks)
Total savings = $25 + ($7 x 10)
Total savings = $25 + $70
Total savings = $95
So, Ruby would have a total of $95 after 10 weeks of saving.
Expression for the amount of money Ruby would have saved in ww weeks:
Let "S" represent the total savings after ww weeks.
Expression: S = $25 + ($7 x ww)

Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%. What was the cost of the sweatshirt before tax?
Answer:$25.00
Step-by-step explanation:
Net Amount (excluding tax) $25.00
Tax (10.0%) $2.50
Gross Amount (including tax) $27.50
in short 10% tax of $25.00 is $27.50.
The required cost of the sweatshirt before tax s given as $24.50.
What is the percentage?The percentage is the ratio of the compositions of matter to the overall composition of matter multiplied by 100.
Here,
Roger paid $27.50 for a sweatshirt. This amount includes a sales tax of 10%.
Cost of the sweatshirt before tax = 27.50 - 10% of 27.50
= 27.50 - 0.1× 27.50
= $24.50
Thus, the required cost of the sweatshirt before tax s given as $24.50.

Use trig identities to show that sec θ − cos θ = tanθ (sin θ)
Use [tex]\sec\theta = \dfrac{1}{\cos{\theta}}[/tex] to get
[tex]\sec\theta -\cos{\theta}= \dfrac{1}{\cos{\theta}}-\cos(\theta})[/tex]
Then find a common denominator:
[tex]\dfrac{1}{\cos{\theta}}-\cos(\theta}) = \dfrac{1}{\cos{\theta}}-\dfrac{\cos^2\theta}{\cos\theta}[/tex]
But now make that one fraction:
[tex]\dfrac{1}{\cos{\theta}}-\dfrac{\cos^2\theta}{\cos\theta} = \dfrac{1 - \cos^2\theta}{\cos{\theta}}[/tex]
But that's just sin^2 on the top
[tex]\dfrac{1 - \cos^2\theta}{\cos{\theta}} = \dfrac{sin^2\theta}{\cos{\theta}} = \dfrac{sin\theta\cdot sin\theta}{\cos{\theta}}[/tex]
Split that fraction up:
[tex]=\dfrac{ sin\theta}{\cos{\theta}}\cdot sin\theta[/tex]
And tan = sin/cos
[tex]=\tan\theta\cdot sin\theta[/tex]

he equation of the line of best fit relating age (in years) and the median height (in cm) of boys is given.
y = 6.5x + 75.5
Which statement below best interprets the slope in the context of the problem?
Answer:
proof: answer is 2/13
1 / 6.5 = m
m = 0.153846154
10/65 = m
m = 2/13
2/13 = m
m = 0.153846154
Therefore we could show multiplication proof
m = 10/65 = m = 2/13
2 x 5 = 10
13 x 5 = 65
Step-by-step explanation:
See attached graph of y = 6.5x+75.5
plotting the graph
1. Mark y intercept at 75.5 as given in the equation
2. find the slope to whole numbers
m = 10 across / 65 across = 6.5 slope
Mapping Pythagoras 10^2 +65^2 = c^2
sqrt 100 + sqrt 4225 = c^2
c^2 = sqrt 4225 = 65.7647322 = 65.8
0.7647322 / 65 = 0.0117651108 = 100th
65 + 0.0117651108 = 65.011765.....
Therefore 10 across / 65.0118 down
or 10 across / 65 down is another way to graph, as seen on graph.
m = 10/65 = m = 2/13
2 x 5 = 10
13 x 5 = 65
