If AB = CD, then 3x+4 is equal to 4x-1

3x + 4 = 4x - 1
Add one to both sides to cancel out.
3x + 5 = 4x
Subtract 3x from both sides to cancel out.
5 = x

Now, substitute the 5 in place of the x in the equation for AB (3x+4)

3(5) + 4
15 + 4
19

Final Answer: B) 19

Hatshy [7]

Answer:

y= (5/3) x + 5

Step-by-step explanation:

y = mx + b

m = (5 - 0)/(0 - (-3)) = 5/3

y = (5/3)x + b

b = 0-(5/3)(-3) = 5

y = (5/3)x + 5

Mr.Mason takes two-thirds of his body weight and drinks that amount of gatorade in ounces per day. If Mr.Mason drinks 118 ounces

denis-greek [22]

The total weight of Mason is 177

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

Given that, Mr.Mason takes two-thirds of his body weight and drinks that amount of gatorade in ounces per day

Mr.Mason drinks 118 ounces each day

Let "x" be the total weight of Mr.Mason

Therefore, we can say,

Two third of body weight = Amount of gatorade drank in ounces per day

Two third of x = 118

$\frac{2}{3} \text{ of } = 118\\\\\frac{2}{3} \times x = 118\\\\2x = 118 \times 3\\\\2x = 354\\\\x = \frac{354}{2}\\\\x = 177$

Thus total weight of Mason is 177
