Answer:

x=3

Step-by-step explanation:

add +5 to both sides to isolate the variable

13x-5=34

+5 +5

that leaves your equation to:

13x=39

divide both sides by 13 to have no coefficent infront of x

13x=39

÷13 ÷13

x=3

Answer:

x = 3

Step-by-step explanation:

To solve this problem we have to try to do the operations that leave the x alone on the left side

13x - 5 = 34

First we are going to have to get the term of -5, for this we simply add 5 from each side of the equality

13x - 5 + 5 = 34 + 5

Then we do the sum

13x = 39

Now we have to take the 13 that multiplies the x, for this we divide both sides by 13

13x/13 = 39/13

Then we do the division and finally we get the value of x

x = 3

The ratio of the units digit to the tens digit in a two-digit number is one-half. the tens digit is two more than the units digi

vodomira [7]

Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2). Write a formula for y in terms of x.

The tens digit is 2 more than the units digit. Using the letters x and y, write out the proper equation.

Now solve your two equations simultaneously for x and y.

A right triangle has a side with length 12 in and a hypotenuse with length 20 in. find the length of the missing leg. (round to

OLEGan [10]

Let the unknown side be "z" inches
Through pythagoras:
${12}^{2} + {z}^{2} = {20}^{2}$
Because the square of the two sides add up to the square of the hypotenuse in a right triangle.

This means that
${z }^{2} = {20}^{2} - {12}^{2}$
${z}^{2} = 400 - 144 = 256$
$z = \sqrt{256} = 16$
So the missing side is 16 inches

Hope this helped

Wittaler [7]

Answer:

46.22

Step-by-step explanation:

Class A total= 23 x 13= 299

Clas B total= 57 x 28= 1596

total score= 299 + 1596 = 1895

total mean= 1895 ÷ (13+28) = 1895 ÷ 41

= 46.22
