If Jasper installs a floor himself, it will take him 7 hours. Working with Yolanda, it will take them 3 hours.
Svetllana [295]

Answer: 5\frac{1}{4} hrs

<u>Explanation:</u>

Jasper: \frac{1}{7} per hr

Yolanda: \frac{1}{x} per hr

Together: \frac{1}{3} per hr

Jasper + Yolanda = Together

\frac{1}{7} + \frac{1}{x} = \frac{1}{3}

(21x)\frac{1}{7} + (21x)\frac{1}{x} = (21x)\frac{1}{3}

3x + 21 = 7x

        21 = 4x

        \frac{21}{4} = x

         5\frac{1}{4}

1/4 times the sum of a number and −3.2 is 1.8. What is the number?
joja [24]

Answer:

10.4

Step-by-step explanation:

Let the number be x

Sum of  x  and -3.2 : x + (-3.2) = x - 3.2

1/4 times the sum of a number and −3.2 = (1/4) * (x - 3.2)

\dfrac{1}{4}* \left( x - 3.2 \right) = 1.8\\\\\Multiply \ the \ whole \ equation \ by \ 4 \\\\4*\dfrac{1}{4} *(x - 3.2) = 1.8*4\\\\\\x - 3.2 = 7.2\\\\Add \  3.2 \ to \ both \ sides\\\\\\x = 7.2 + 3.2\\

x = 10.4
