<h3>Answer with Step-by-step explanation:</h3>

Let Jane worked for x hours

John worked five less than twice as many hours as Jane

i.e. John worked for 2x-5

Together they worked 97 hours

i.e. x + 2x -5 =97

i.e. 3x -5 =97

i.e. 3x = 102

i.e. x= 34

and 2x - 5= 2×34-5

= 63

Hence, Jane worked for 34 hours

and John worked for 63 hours

Answer:

No, there is no proportional relationship

Step-by-step explanation:

<u>The proportional relationship is:</u>

y = kx, which is a special form of linear equation, with zero y-intercept

<u>In the given case we have:</u>

y = 4.5x + 10

This is a linear function but not proportional relationship because it has y-intercept, different than zero

Having a small brain moment, can you please help and show work

Answer:

The value if x is 0.9875.

Step-by-step explanation:

First, we have to get rid of brackets by expanding :

$0.5(2x + \frac{3}{4} ) - \frac{1}{3} (0.1 + x) = 1$

$0.5(2x) + 0.5( \frac{3}{4} ) - \frac{1}{3} (0.1) - \frac{1}{3} (x) = 1$

$x + \frac{3}{8} - \frac{1}{30} - \frac{1}{3} x = 1$

Next you have to collect like terms :

$x - \frac{1}{3} x + \frac{3}{8} - \frac{1}{30} = 1$

$\frac{2}{3} x + \frac{41}{120} = 1$

Lastly, you can solve x :

$\frac{2}{3} x = 1 - \frac{41}{120}$

$\frac{2}{3} x = \frac{79}{120}$

$x = \frac{79}{120} \div \frac{2}{3}$

$x = \frac{79}{80}$

$x = 0.9875$
