Given:
Carmen rents roller skates for $5 plus $2 for every hour she uses them.
To find:
The expression for the total cost to rent roller skates. Then find the total cost if Carmen rest them for 4 hours.
Solution:
We have,
Fixed rent = $5
Additional rent = $2 per hour.
Let x be the number of hours.
So, additional rent is $2x.
Now,
Total rent = Fixed rend + Additional rent
= $(5+2x)
So, the expression for total cost is $(5+2x).
Carmen rent them for 4 hours. So, x=4 and the total cost is
[tex]\text{Total cost}=5+2(4)[/tex]
[tex]\text{Total cost}=5+8[/tex]
[tex]\text{Total cost}=13[/tex]
Therefore, the total cost of 4 hours is $13.

(2k-7)/5+1-(k-1)/3
Pls help
Answer:
2k/5 + 1 + -k+1/3
Step-by-step explanation:
(2k - 7)/5 + 1 - 1 x (k - 1)/3
Simplify
Combine multiplied terms into a single fraction
2k - 7/5 + 1 - 1 x k - 1/3
2k- 7/5 + 1 + -1(k - 1)/3
Distribute
2k - 7/5 + 1 + -1(k - 1)/ 3
2k - 7/5 + 1 + = -k + 1/3
Solution
2k - 7/5 + 1 + -k + 1/3
Answer:
[tex]\frac{k-1}{15}[/tex]
Step-by-step explanation:
[tex]\frac{(2k - 7)}{5} + 1 - \frac{(k-1)}{3}[/tex]
[tex]\frac{3(2k -7)}{3 ( 5)} + \frac{15 * 1}{15 * 1} - \frac{5(k-1)}{5 * 3}[/tex]

= Total points - Questions answered correctly
= 180 - 135
= 45 problems
The first two terms of a sequence are a1 =4 and a2= -2. Let a3 be the third term when the sequence is arithmetic and let b3 be the third term when the sequence is geometric. Find a3+b3
Answer:
a3 + b3 = -7
Step-by-step explanation:
When the sequence is A.P
a1 =4 and a2= -2
Common difference,d = a2 - a1
= -2 - 4
d = -6
a3 = third term
a3 = a1 + 2d
= 4 + 2(-6)
= 4 - 12
= -8
a3 = -8
When the sequence is geometric
a1 =4 and a2= -2
Common ratio, r = a2/a1
= -2/4
r = -1/2
Or
r = -0.5
b3 = third term
b3 = ar²
= 4 * (-1/2)²
= 4 * 1/4
= 4/4
= 1
b3 = 1
a3 + b3 = -8 + 1
= -7
a3 + b3 = -7

Answer:
The 2nd option:
1.339×10⁶
Step-by-step explanation:
To find the combined capacity, add the two values together so:
(8.12×10⁵ ) + ( 5.27 × 10⁵ )
It will be simpler to add if you change it out of its
standard form
812000+527000
= 1339000
Now you can write in back in standard form, which will be
1.339×10⁶
Warren made 5 pans of brownies. He will slice the brownies into pieces, and each piece will be 1/10 of the size of a pan. How many slices of brownies will Warren create? a. 10 b. 25 :c. 50. d. 100
Answer:
c
Step-by-step explanation:
If a piece is equal to 1/10 of a pan , a pan would make 10 brownies
5 pans would make , 10 x 5 = 50 brownies
Answer: c
Step-by-step explanation: each pan is 10 slices so if you multiply that with how many pans you have which is 5 and 5 x 10 = 50
Facrorise fully x^2-43^2
Answer:
(x - 43)(x + 43)
Step-by-step explanation:
x² - 43² ← is a difference of squares and factorises in general as
a² - b² = (a - b)(a + b), then
x² - 43²
= (x - 43)(x + 43)
Answer:
(x - 43)(x + 43).
Step-by-step explanation:
This is the difference of 2 squares:
a^2 - b^2 = (a - b)(a + b) so here we have:
x^2 - 43^2 = (x - 43)(x + 43).

Use Pythagorean Theorem to solve for x.
HELP ME PLZZZZ!!!! ASAP
Answer: [tex]2\sqrt{22}[/tex]
Step-by-step explanation:
Pythagorean theorem: [tex]a^{2} +b^{2} = c^{2}[/tex], where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.
[tex]9^{2} +b^{2} = 13^{2}[/tex]
[tex]81 +b^{2} = 169[/tex]
Since we don't know what [tex]b^{2}[/tex] is, we're going to isolate it by subtracting 81 on both sides
[tex]b^{2} = 88[/tex]
We have to square root both sides in order to find out b (or x in the problem).
[tex]\sqrt{b^{2}} = \sqrt{88}[/tex]
When you put this on a calculator it would result in [tex]2\sqrt{22}[/tex] which is the answer d in the problem.

Thanks and stay perfect.
Answer:
22 cards
Step-by-step explanation:
Set up a ratio.
[tex]\frac{34}{29+x} =\frac{2}{3}[/tex]
[tex]58+2x=102[/tex]
[tex]2x=44[/tex]
