y-y1= m(x-x1)

y- 1 = 6/5(x-5)

y -1 = 6/5X - 6

whats the answer to 3x+4=6x+19

Answers

Answer:

x = -5

Step-by-step explanation:

[tex]3x + 4 = 6x + 19\\-3x + 4 = 19\\-3x = 15\\x = -5[/tex]

3x+4=6x+19 subtract 3x from both sides
4=3x+19 subtract 19 from both sides
-15=3x divide by 3 on both sides
-5=x
The answer is x=-5

5 positive integers are arranged in ascending order, as follows:
7, 8, 11, 11, X
The median and the range are equal.
Find 2.

Answers

Answer:

X = 18.

Step-by-step explanation:

The median = 11 so the mean is also 11 (given).

So mean  = 11 = (7 + 8 + 11 + 11 + X) / 5

(37 + x)/ 5 = 11

x + 37 = 55

x = 55 - 37 = 18.

Adam purchased some items at the school store. He bought 3 pencils for $0.15 each and 5 single-subject notebook
If these items cost a total of $6.45, what was the cost of each notebook?
O A. $1.20
B. $1.26
O c. $1.29
OD. $1.38

Answers

Answer:

The answer is A

Step-by-step explanation:

Fist multiply 3 and .15 to get .45 for 3 pencils. Then subtract .45 from 6.45 and get 6. Then divided 6 by 5 to get 1.2 for each book

i think the answer is a: $1.20

my work:

3 x 0.15 = 0.45.

6.45 - 0.45 = 6.00

6.00 / 5 = 1.20

and i checked my work by doing 1.20 x 5 + 0.40 = $6.45.

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50. Let SSS represent the number of stacks of pancakes that Benjamin buys.

Answers

Answer:

4 stacks of packages

4 * 4 = 16 pieces of pancake

Step-by-step explanation:

Maximum amount to spend ≤ $30

Milk chocolate = $3.25

Pancakes per stack = 5.50 (sold in stacks of 4)

Let number of stacks = s

In equality terms :

3.25 + 5.50s ≤ 30

5.50s ≤ 30 - 3.25

5.50s ≤ 26.75

s ≤ 26.75 / 5.50

s ≤ 4.86

Hence, 4 stacks of pancakes can be purchased

Answer:

3.25+5.50S<30

Step-by-step explanation:

Benjamin can afford at most 16 pancakes
