Answers

Answer 1

Answer:

Answer:

7 -10 -30 -53

Step-by-step explanation:

47-2 = 45

45-5 = 40 (2+3=5)

40-8 = 32 (5+3=8)

32-11 = 21(8+3=11).........

21-14 = 7

7-17 = -10

-10 -20 = -30

-30-23 = -53

lalo has 1500 minutes per month on his cell phone plan. how many more minutes can he use if he has already talked for 785 minutes?

Answers

Answer:

Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.

Step-by-step explanation:

Total number of minutes per month lalo has on his cell phone plan = 1500

Number of minutes he has already talked in that month = 785

Number of minutes available to talk = total number of minutes he has - total number of minutes he has already used.

= 1500 - 785

= 715 minutes.

Thus, Lalo can talk for 715 minutes more in that month if he has already talked for 785 minutes.

All you have to do is subtract 1500-785 in order to find the number of minutes left for him.
1500-785=715 more minutes left

Given the trinomial, what is the value of the coefficient 'B' in the factored form?2x2 + 14xy − 36y2 = 2(x + By)(x − 2y)

B= ____________

Answers

2x2 + 14xy -36y2 = (2x+2By)(x - 2y)
2x2 + 14xy -36y2 = 2x2 -4xy +2Bxy -4By2
2x2 + 14xy -36y2 = 2x2 + (2B-4)xy -4By2
since the coefficient of y2 is equal so
-4B = -36
B = 9
if you want to make sure subs in coeeficient of xy by B=9
and you'll get 14 so the answer is right
B=9

Answer:

the answer is B=9 i think

NEED HELP ASAPEstimate the sum of 3.19 + 1.69 = ________ by rounding each addend to the nearest tenth.
A. 3
B. 3.9
C. 4
D. 4.9

Answers

Answer:

Step-by-step explanation:

3.19 become 3.20 . 1.69 becomes 1.70. Then 3.20 plus 1.70 is 4.90 or 4.9.

Answer:

D. 4.9

3.19 -> 3.2

1.69 -> 1.7

3.2 + 1.7 = 4.9

Point P has coordinates (2,3). Point Q is symmetric to point P with respect to the line x = 4. What are the coordinates of point Q. Im wondering how you solve this. I think it's (3,6) A. (2,5)
B. ( 5,3)
C. (3,6)
D. (6,3

Answers

You are given the first point (2, 3) and a line x = 4. If you go ahead and graph these, it makes it a little more clear when they say that point p is symmetric with point Q with respect to the line x = 4.

Line x = 4 is the line of symmetry, so point Q is reflected across it. Point p has an x value of 2 (2 away from the line of symmetry, so point Q's x value has to be 2 away on the other side... 6. The y value is unchanged so your point is

Garrett is a member of a movie club. He pays a monthly service fee of $5.75 and $2.50 for each movie he rents. Which expression represents how much money he will spend for renting x amount of movies a month?

3.25x

5.75x + 2.50

2.50x + 5.75

9.25x

Answers

ANSWER: 2.50x + 5.75

REASON: x represents the number of movies and if each movie is 2.50, then 2.50x will tell u what u paid for the movies, but u cant forget the monthly service fee of 5.75. So lets say u rent 5 movies, 2.50(5) + 5.75 = 12.50 + 5.75 = 18.25, so u would have spend 18.75 for the month

Answer:

$\$2.50x+\$5.75$
