Answer:
x=3
PR=10
Step-by-step explanation:
This is an isosceles triangle, indicated by the black markers on angles P and Q. This also means that sides PR and QR are equal.
That in mind, to solve for x set the two expressions equal to each other and solve for x.
3x+1=5x-5 (subtract 1 from the left side and 5 from the right. Do the same from both sides)
-2x = -6 (divide by -2)
X=3
To find the measurement for PR, simply plug in the value for x into the equation for PR
3(3) +1
9+1 =10

a birthday cake at the bakery was $30 originally. During a sale, a discount of 28% was given. A further 15% discount was given to those customers who ordered a month earlier. How much would a customer who orders a month earlier need to pay for the birthday cake during the sale?
Answers
Answer:
$18.36
Step-by-step explanation:
In this question, we have to find the cost of the cake for the customer who orders a month early.
We know that the original price of the cake is $30.
We also know that there was a 28% discount and a 15% discount added to the purchase.
Remember, You don't add discount percentages together, you discount the prices separately.
Solve:
First, apply the 28% discount.
30 · 0.28 = 8.40
30 - 8.40 = 21.60
Now apply the 15% discount to the new price.
21.60 · 0.15 = 3.24
21.60 - 3.24 = $18.36
They needed to pay $18.36 for the cake.

A sale is taking place at your local sporting goods store. The store has advertised that all items in the store will be 10% off. If you spend a total of $150.32, determine the amount you would have spent had there not been a sale. Round your answer to the nearest cent.
a.
$167.02
c.
$156.58
b.
$163.54
d.
$165.35
Answers
Answer: $167.02
Step-by-step explanation:
Amount spent when there's discount
= $150.32
Discount = 10%
Since there's a discount of 10%, it means that (100% - 10%) = 90% of the value of the good was paid.
Let the original value be x.
Therefore, 90% of x = $150.32
90% × x = $150.32
0.9 × x = $150.32
0.9x = $150.32
x = $150.32/0.9
x = $167.02
The value is $167.02
at a sale this week, a desk is being sold for $589. This is a 38% discount from the original price. What is the original price? WILL GIVE BRAINLIEST IF CORRECT! ( you have to have an explanation!)
Answers
Answer: 950
Step-by-step explanation: x= original price
so we know that the desk cost x dollars and after 38% discount the desk was 589
589= discounted price= original price x-the 38%
589=x-0.38x=0.62 x
x=589/0.62=950
The original price of the desk is $950.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
The original price = 100%
Selling price = $589
Discount = 38%
100% - 38% = 589
62% = $589
Multiply 100/62 on both sides.
100% = 100/62 x 589
100% = $950
Thus,
The original price of the desk is $950.

[tex]f(x) = 2x^2 - 7x - 6\\f(6) = 2(6)^2 - 7(6) - 6=2*36-42-6=24[/tex]
Answer:
f(6) = 24

f(x) = 2x² – 7x – 6: f(6)
f(6) = 2(6)² - 7(6) - 6

Which THREE pairs of measurements are possible side lengths for a 30-60-90 triangle?
C= 30, B = 90, A = 60
1. AB+4, BC = 4√3
2. 2√3, AC = 2
3. AB = 3, AC = 3√3
4. BC = 10, AC = 4√3
5. AB = 7, AC = 14
6. AB = 11, BC = 11√3
Answers
Answer:
1, 5 and 6.
Step-by-step explanation:
The sides of this triangles has lengths in the ratio x : √3x : 2x where 2x is the hypotenuse.
When C = 30, the side AB is the small leg (=x).
When B = 90, the hypotenuse is AC ( =2x).
When A = 60, the larger leg is BC (=√3x).
1. AB = 4, BC = 4√3 :- Are possible legs.
5 AB = 7, AC = 14. :- AB = small leg, AC = hypotenuse.
6. AB = 11, BC = 11√3:- AB = small, BC = larger leg.
Answer:
1, 5, and 6

Step-by-step explanation:
Let's solve each answer and see which one matches.
Note that in each case, you simply add or subtract from x inside the radical to move left or right respectively. Similarly, just add or subtract to the full expression to move up or down respectively. Doing so we get:
a) [tex]f(x) = \sqrt[3]{x + 7} + 3[/tex]

A cereal company is putting 1 11 of 4 44 prizes in each box of cereal. The prizes are evenly distributed so the probability of winning any given prize is always 1 / 4 1/41, slash, 4.
Answers
Answer:
0.75
Step-by-step explanation:
The complete question is attached below.
The dots on the numbers of the dot plot represent the number of boxes it took Vera to get all the prizes.
Therefore, the probability of getting all the prizes in 9 or fewer boxes is the sum of the number of times it took her to get 4 prizes in 9 boxes or fewer.
Hence:
P(x ≤ 9) = P(x = 4) + P(x = 5) + P(x = 6) + P(x = 7) + P(x = 8) + P(x =9)
P(x ≤ 9) = (4 / 36) + (6 / 36) + (3 / 36) + (4 / 36) + (4 / 36) + (6 / 36)
P(x ≤ 9) = 27 / 36
P(x ≤ 9) = 3 / 4 = 0.75
