valina [46]

$\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}$

Let's solve ~

$\qquad \sf \dashrightarrow \: 2m - 3 - 5 = - m + 10$

$\qquad \sf \dashrightarrow \: 2m + m = 10 + 3 + 5$

$\qquad \sf \dashrightarrow \: 3m = 18$

$\qquad \sf \dashrightarrow \: m = 18 \div 3$

$\qquad \sf \dashrightarrow \: m = 6$

Hence, value of m is 6

A car travels at a speed of 85 mph how far will it travel in 15 minutes

Vladimir [108]

Answer:

106.25 mph

Step-by-step explanation:

since the car travels at 85 miles per hour we divide it by 60 seconds in order to find how many miles is it to get in a minute

=> 85mph ÷ 60

divide 85 by 60

=> 1.416

multiply 1.416 by 15 to get how many miles it to go in 15 minutes

=> 21.25

then add it to 85

=> 106.25

7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the gard

galben [10]

Answer: $15r^2-21r+5$

Step-by-step explanation:

Given: Perimeter of triangular garden = $25r^2 - 9r + 14$

The sum of two sides of the garden = $10r^2 + 12r + 9$

Perimeter is the sum of all sides of a triangle.

Third side = Perimeter of triangular garden - sum of two sides of the garden

$=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5$

The expression represent the third side = $15r^2-21r+5$ .
