B is 5, you can solve this by first finding the value of a, which is 2, and then plug it into the other equation. 8+2=10 so we must also make the other side 10. We then do 10-5=5, 5 is the value of b

What is the solution of the equation 17 = 3x − 4?
pogonyaev

Answer:

<em>x = 7</em>

Step-by-step explanation:

Simplifying

17 = 3X + -4

Reorder the terms:

17 = -4 + 3X

Solving

17 = -4 + 3X

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '-3X' to each side of the equation.

17 + -3X = -4 + 3X + -3X

Combine like terms: 3X + -3X = 0

17 + -3X = -4 + 0

17 + -3X = -4

Add '-17' to each side of the equation.

17 + -17 + -3X = -4 + -17

Combine like terms: 17 + -17 = 0

0 + -3X = -4 + -17

-3X = -4 + -17

Combine like terms: -4 + -17 = -21

-3X = -21

Divide each side by '-3'.

X = 7

Simplifying

X = 7

If you are solving y 2+2y=48 by completing the square, the next line would be
snow_tiger [21]

For this case we have the following equation:

y ^ 2 + 2y = 48

By completing squares we have:

Step 1:

Add (\frac {b} {2}) ^ 2 on both sides:

y ^ 2 + 2y + 1 = 48 + 1

Step 2:

We rewrite the equation:

(y + 1) ^ 2 = 49

Step 3:

We solve the equation:

y = \pm \sqrt {49} -1\\y = \pm7-1

Solutions:

y = 6\\y = -8

Answer:

the next line would be:

y ^ 2 + 2y + 1 = 48 + 1

Connie and two of her friends completed a 10 mile bike relay each friend wrote an equal part of the race what distance did each
grin007 [14]
If Connie and her two friends are completing the relay, this means that there are three people. 

If they each rode an equal part of the race this means that we must divide the 10 miles (the distance ridden) by 3 (the number of racers).

As a fraction this equals 3 and 1/3 and in a decimal this equals approximately 3.33
