Answer:

x = $\frac{-5}{7}$

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x+4(x+3)=7

3x+(4)(x)+(4)(3)=7(Distribute)

3x+4x+12=7

(3x+4x)+(12)=7(Combine Like Terms)

7x+12=7

Step 2: Subtract 12 from both sides.

7x+12−12=7−12

7x=−5

Step 3: Divide both sides by 7.

$\frac{7x}{7} = \frac{-5}{7}$

Find the unit rate with the numbers 12 and one and one half

kati45 [8]

Answer:

The value of the unit rate is 8

Step-by-step explanation:

we know that

To calculate the unit rate simply divide the first number by the second number

$12:1\frac{1}{2}$

Convert mixed number to an improper fraction

$1\frac{1}{2}=1+\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}$

substitute in the expression above

$12:\frac{3}{2}=\frac{24}{3}=8$

Solve the equation a=m-n for the variable n.

amid [387]

Our objective is to isolate n one side of the equation. The steps are as follows...

a=m-n
(Add n to both sides)
a+n=m-n+n
(The -n and +n cancel out, on the right side of the equation)
a+n=m
(Now subtract a from both sides)
a+n-a=m+a
(The +a and -a cancel out, on the right side of the equation)
n=m+a
