Question

2.4+10m=6.89 what does m equal

Answer 1

Answer:

m = 0.449

Step-by-step explanation:

Isolate the variable, m. Note the equal sign, what you do to one side, you do to the other. Remember to do the opposite of PEMDAS.

PEMDAS is the order of operation & =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 2.4 from both sides:

2.4 (-2.4) + 10m = 6.89 (-2.4)

10m = 6.89 - 2.4

10m = 4.49

Divide 10 from both sides:

(10m)/10 = (4.49)/10

m = 4.49/10

m = 0.449

0.449 is your answer for m.

Answer 2

Answer:

m = 0.449

Step-by-step explanation:

$2.4+10m=6.89\\\\\mathrm{Subtract\:}2.4\mathrm{\:from\:both\:sides}\\2.4+10m-2.4=6.89-2.4\\\\Simplify\\10m=4.49\\\\\mathrm{Divide\:both\:sides\:by\:}10\\\frac{10m}{10}=\frac{4.49}{10}\\\\Simplify\\m=\frac{4.49}{10}\\\\\left(\mathrm{Decimal}:\quad m=0.449\right)$
