1 answer:
Crank3 years ago
5 0

Step-by-step explanation:

2.5x+12=32

We move all terms to the left:

2.5x+12-(32)=0

We add all the numbers together, and all the variables

2.5x-20=0

We move all terms containing x to the left, all other terms to the right

2.5x=20

x=20/2.5

x=8

A boat has a speed of 9 mph in calm water. It takes the boat 4 hours to travel upstream but only 2 hours to travel the same dist
Dmitrij [34]
D=4(9-c) and d=2(9+c)

d=36-4c and d=18+2c

Since d=d

18+2c=36-4c  add 4c to both sides

18+6c=36  subtract 18 from both sides

6c=18  divide both sides by 6

c=3

So the speed of the current is 3mph

What is the value of x in the equation 13 x minus 2 (8 + 5 x) = 12 minus 11 x?
AnnZ [28]

The value of n in given proportion is 16

<u><em>Solution:</em></u>

We have to find the value of "n" in the proportion

<em><u>Given proportion is:</u></em>

<em><u></u></em>\frac{n}{28} = \frac{4}{7}<em><u></u></em>

We can solve the above proportion by cross-multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

->\frac{n}{28} = \frac{4}{7}

-> 7 *  n = 4 * 28

-> n = \frac{4 * 28}{7}

-> n = 4 * 4 = 16

Thus the value of n in given proportion is 16
