Someone anyone please please I am begging help me

Answer:

Step-by-step explanation:

Since (8x-20) and (3x+2) are two sides of the angles on one plane, we can structure them into an equation to find x.

(8x-20) + (3x+2) = 180

We want x to be on one side and all the numbers to be on the other. But first, we must combine our two problems.

-20 + 2 = -18; 8x + 3x = 11x

So now our equation is:

(11x-18) = 180

In order to move our numbers to one side and leave our x's on the other, we must inverse our additions/subtractions/etc.

180 + 18 = 199

11x = 199

199/11 = 18.1

x=18.1!

Regards!

Jessica Reads a story about a turtle that swam 16 feet in 24 seconds. She assumes that the time that it takes the turtle to swim
Zigmanuir [339]

Answer:

Time (secs) => distance (ft)

1 => ⅔

15 => 10

24 => 16

45 => 30

Step-by-step explanation:

Equation to represent this proportional relationship is d = tk, where,

t = time

d = distance

k = constant of proportionality

To complete the table, let's find k given that the turtles swarm 16 ft (d) in 24 secs (t).

Substitute d = 16, t = 24 into the equation.

d = tk

16 = 24k

\frac{16}{24} = k (division property of equality)

\frac{2}{3} = k

Let's complete the table by substituting the value of k and the other given value of t or d, as the case may be:

For 1 sec, let's find distance (d):

d = tk

d = 1*\frac{2}{3}

d = ⅔ ft

For 10 ft, let's find the time (t) taken:

d = tk

10 = t*\frac{2}{3}

Multiply both sides by 3

10*3 = t*\frac{2}{3}*3

30 = t*2

Divide both sides by 2

\frac{30}{2} = \frac{t*2}{2}

15 = t

t = 15 secs

For 45 secs, let's find distance (d):

d = tk

d = 45*\frac{2}{3} = 15*2

d = 30 ft

A field has a perimeter of 1.48 kilometers it is 460 meteres long how wide is the field
Vika [28.1K]
280 meters wide. 
Step 1: Convert kilometers to meters. 1.48=1480
Step 2: Multiply the side length that you have by 2. 2x460=920
Step 3: Subtract 920 from 1480. 1480-920=560.
Step 4: Divide 560 by 2. 560/2=280
There is your answer!
