(T+10.5) + 2t + 90 = 180
Masja [62]

Answer:

x = 26.5

Step-by-step explanation:

Step 1: Write equation

(t + 10.5) + 2t + 90 = 180

Step 2: Solve for <em>t</em>

<u>Combine like terms:</u> 3t + 100.5 = 180

<u>Subtract 100.5 on both sides:</u> 3t = 79.5

<u>Divide both sides by 3:</u> t = 26.5

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

<u>Substitute:</u> (26.5 + 10.5) + 2(26.5) + 90 = 180

<u>Parenthesis:</u> 37 + 56 + 90 = 180

<u>Add:</u> 180 = 180

∴ x = 26.5

The slope of a line is 7/10 . One point on the line has coordinates (1, 2). Which ordered pair represents another point on the l
mash [69]
(x,y)

y=mx+b
m=slope
b=yintercept
slope=7/10
one point is (1,2) or x=1, then y=2
find b
y=7/10x+b
2=7/10(1)+b
2=7/10+b
minus 7/10 both sides
1 and 3/10=b
13/10=b
y=7/10x+13/10
input values for x and get values for y
one point is (0,13/10)

Complete the equation of the line through<br> (-10, 3) and (-8, -8).
ad-work [718]

The answer is y = -5.5x - 52.

First, let's find the slope of the line.

m = Δy/Δx

  • m = -8 - 3 / -8 - (-10)
  • m = -11 / -8 + 10
  • m = -11/2
  • m = -5.5

Now, substitute the slope and one of the given points in the point slope equation.

<u>y - y₁ = m (x - x₁)</u>

  • y - 3 = -5.5 (x - (-10))
  • y - 3 = -5.5 (x + 10)
  • y - 3 = -5.5x - 55
  • y = -5.5x - 52

Rectangle prism with length 20inches, width 18inches and height 10inches. Suppose water is pumped out of the aquarium at a rate
Anettt [7]

Answer:

10 minutes

Step-by-step explanation:

To solve this , we need to first calculate the volume of the rectangular prism. Let’s say this is V.

Mathematically, V = w h l where w, h and l are width , height and length respectively.

V = 20 * 18 * 10 = 3600 in^3

Now to get the number of minutes, we divide the volume by the draining rate.

That would be 3600/360 = 10 minutes
