distribute the $7$ and $5$ :

$7(4+t)-5(t+1)=\\28+7t -5t -5$ (collect like-terms)

$28-5 +7t-5t=\\23+2t$

$23+2t$ or $2t+23$ is your answer. hope this helps <3

Which equation represents a line which is parallel to the line y=5/6x−7?

lyudmila [28]

Answer: The choice will be any equation where the slope is the same and the y-intercept is different.

$y=\frac{5}{6}x + b$

Step-by-step explanation: Using slope-intercept form, y = mx + b,

m is the slope, b is the y-intercept.

Parallel lines will have the same slope.

So, you are looking for another equation that has 5/6 as the coefficient of x.

It could be an equation in the form 6y + 5x = _b_ where the constant, b, could be anything except -42, as that would be an identical line, not parallel.

Plz help! Question is below!

Paraphin [41]

Answer:7 Feet below ground

Step-by-step explanation:

1st: Since it says our hole is dug down 8ft to begin with we can start with x=-8

2nd: After a short break, it says we dug down another 3 feet which is -8-3=-11 which shows we are 11 feet below ground where the negative number showcases we are below ground level.

3rd:

After this we are shown a tractor accidentally fills in the hole with 4ft of dirt which signifies that we lose some of our holes height below ground so we would add four: -11+4=-7 this shows that we are finally seven feet below ground.
