Correct question is;
Caitlin purchased a prepaid phone card for $20. Long distance calls cost 7 cents a minute using this card. Catin used her card only once to make a long distance all the remaining credit on her card is $16.8. how many minutes did her call last?
Answer:
45 minutes 43 seconds
Step-by-step explanation:
We are told that she purchase the prepaid phone card for $20.
Now she has $16.8 after making the call.
Therefore;
Amount spent on the call = 20 - 16.8 = $3.2
We are told that the long distance call costs 7 cents per minute. Which is $0.07 per minutes
Thus, time spent = $3.2/$0.07 = 45.714 minutes or 45 minutes 43 seconds
Simplify:
(3x+4) (2x - 5)
Answer:
6x^2-7x-20 (c)
Step-by-step explanation:
(3x+4)(2x−5)
=(3x+4)(2x+−5)
=(3x)(2x)+(3x)(−5)+(4)(2x)+(4)(−5)
=6x^2−15x+8x−20
=6x^2-7x-20
Answer:
C
Step-by-step explanation:
Given
(3x + 4)(2x - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
3x(2x - 5) + 4(2x - 5) ← distribute both parenthesis
= 6x² - 15x + 8x - 20 ← collect like terms
= 6x² - 7x - 20 → C
0.5×- 1.2 =0.4× + 3.3

3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}
Answer:
Step-by-step explanation:
Alright all we need to know is to understand our brackets
So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}
3+20-5-9+4-3(1-5)
Step 2
3+20-5-9+4-3(1-5) Simplify
18-9+4-3(1-5)
Step 3
18-9+4-3(1-5)
13-3(1-5)
13-(-12) Here is the tricky part (We aren't going to subtract because the brackets multiply the equations
So,
13+12=25
Your answer is 25
Which choices are equivalent to the quotient below? Check all that apply. 100 20 A. 15 13 B. 5 25 5 D. 13 15 E. F. 5 SUBMIT
The quotient of 100/20 is 5. The correct option is F.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
We have the expression:
100/20
To find the quotient:
Quotient: The number resulting from the division of one number by another.
Use division operation.
100 / 20
Simplifying,
10x10 / 2 x 10
Factor out 10.
We get,
10/2
So, 10/2 = 5
Therefore, the quotient is 5.

what is the equation of the line that passes through the point (-5,1) and has a slope of -1/5?
Answer:
x + 5y = 0
Step-by-step explanation:
y = mx + b
y = -1/5 x + b
1 = -1/5 (-5) + b
1 = 1 + b
b = 0
y = -1/5 x
5y = -x
x + 5y = 0

Answer:
Add 7 to both sides of the equation
3 − 7 + 7 = 8 + 7
Simplify
3m = 8 + 7
3 = 1 5
Divide both sides of the equation by the same term
3 = 1 5
3 / 3 = 1 5 /3

Un embalse estaba lleno a finales del mes de mayo. En el mes de junio se consumieron 3/10 de sus reservas y a finales de julio solo quedaba la mitad. ¿Qué fracción del embalse se consumió durante el mes de julio?
The English translation of the question is
A reservoir was full at the end of May. In the month of June 3/10 of its reserves were consumed and at the end of July only half remained. What fraction of the reservoir was consumed during the month of July?
Answer:
1/5 of the Reservoir will be consumed in the month of July.
Step-by-step explanation:
We are given
Full reservoir at the end of month May. In the month of June 3/10 of the reservoir was consumed.
Amount present in the Reservoir at the end of the month June will be = 1 -3/10
= 7/10
Now this 7/10 of the Reservoir will be used for the next month which is July
It is given that at the end of July only 1/2 of the Reservoir is remained that means the amount that was left at the end of the Month June will be used for the month July. So the amount consumed in the month of July will be
Amount consumed = 7/10 - 1/2
= 2/10 = 1/5
Therefore 1/5 of the reservoir will be consumed in the month of July.
