Answer:
80 ft
Step-by-step explanation:
<em>hey there,</em>

< We know that the rope is 3 pieces long. To make this into an equation, let's just write x + y + z = 150.
Assuming "y" is our second piece, we can tell y = 2x, because it is two times the size of the first piece, which is "x". We also know "z" (our third piece): z = 30.
We can try inputting all the things we know now. x + (2x) + 30 = 150. From here, we can find that x = 40. Since y is our second piece, y = 2x, so 2 x (40) = 80. The second piece would be 80 feet long. >

Answer:
y= -1/5x + 5
Step-by-step explanation:
An easy way to remember which one is the slope and which one is the intercept in a slope-intercept equation is that the number next to x is always the slope and the number that's a loner is the y-intercept. Hope this helps!
Answer:
The expression is
Step-by-step explanation:
<u><em> Step(i):-</em></u>
Given variable start with 'x'
The variable 'x' is divided by '3' so
<u><em>Step(ii):</em></u>-
The variable 'x' is divided by '3' so and after that subtract '6'
Then the expression
We can write it down as:
Jill = x
Ned = 1,5 * x
Tom = x + 15
So:
190 = x + 1,5 * x + x + 15
190 = x + 1,5x + x + 15
190 = 2x + 1,5x + 15
190 = 3,5x + 15 / - 15 (both sides)
175 = 3,5x / ÷ 3,5 (both sides)
x = 50
So:
Jill = 50 kg
Ned = 1,5 * 50 = 75 kg
Tom = 50 + 15 = 65 kg
