Answers

Answer:

The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to  10 a.m. was -10 1/2 degrees

Step-by-step explanation:

Initially, the temperature was 3 1/2 degrees Fahrenheit at 3 a.m. From 3 a.m., the temperature change at 1 1/2 degrees per hour for the next 7 hours. This means that the temperature change in the next 7 hours is:

Temperature change = 7(-1 1/2) = -10 1/2

In the next 7 hours from 3 a.m. to 10 a.m., that is at 10 a.m. (3 a.m. + 7 hours), the temperature change was -10 1/2 degrees Fahrenheit.

Hence:

The equation 7(-1 1/2) = -10 1/2 means that the temperature change from 3 a.m. to  10 a.m. was -10 1/2 degrees

Factor the expression using 3 as one factor.

3x+15

Answers

3(3)+15 which equals 24

Answer: 3(x+5) ✅

 

Step-by-step explanation:

Hii, do you need to factor the expression 3x+15? No problem! (:

Note that 3x and 15 have a "3" in common.

To factor it out, we can divide 3x and 15 by 3 first.

x+5

Put parentheses around x+5

(x+5)

Now put the 3 that we just factored out outside these parentheses

3(x+5)

Cans of tuna cost $3.00 for 6 ½ ounces. At that rate, how much would 104 ounces of tuna cost?

HELP FOR POSSIBLE BRAINLIEST!

Answers

Answer:

$48.00

Step-by-step explanation:

$3.00 / 6.5 oz = [unknown $] / 104 oz

unknown $ = 104 oz * $3.00 / 6.5 oz

unknown $ = 16 * $3.00 ((oz/oz cancels out))

unknown $ = $48.00

Answer:$48

6 1/2 = 6.5

Step-by-step explanation:

If $3.00 for 6.5 (6 1/2) ounces

(3 x 2 = 6) Then $6.00 is for 13 ounces

(3 x 10 = 30) then $30.00 is for 65 ounces

(3 x 15 = 45) then $45.00 is 97.5 ounces

(3 x 16 = 48) then $48.00 is 104 ounces.

If you multiply the dollars you will also have to multiply the ounces with the same number you multiplied with dollars.
