Yes because when you replace x with 5 you get the equation 5+3=8 and 5+3 is in fact 8 so 8=8

<h2><u>Answer: </u></h2><h2>  \boxed{x=5}</h2><h2 /><h2><u>Solution Steps: </u></h2>

______________________________

<u />

<h3>1.) <u>Subtract 3 from both sides:</u></h3>
  • 3-3= Cancels Out
  • 8-3=5

 - When solving problems like these (One-Step Equations,) to get x alone you must do the opposite of what you see.

- In this situation we have a positive 3. So to get rid of both numbers you do the opposite: Opposite of +3 is -3. So you subtract 3 from each number.

12=10(s+4)+50 what is the written problem to this can you help me with the answer
muminat

Answer:

s = -7.8

Step-by-step explanation:

from the question 12=10(s+4)+50

<u>first step</u>

open the bracket and evaluate for the value of s

12=10(s+4)+50

12 = 10s + 40 + 50

12 = 10s + 90

collect or combine the like terms

12-90 = 10s

-78 = 10s

divide both side by 10

-78/10 = 10s/10

-7.8 = s

therefor s = -7.8

PLEASE HELP PLEASE<br> question: Your mass on earth is 50 kilograms. What is your mass on the moon?
USPshnik [31]

Answer:

No matter if you are on Earth, the moon or just chilling in space, your mass does not change. But your weight depends on the gravity force; you would weigh less on the moon than on Earth, and in space you would weigh almost nothing at all. Where ever you are, your mass will always stay the same.

Please help me with this
erma4kov [3.2K]

Answer:

3/8

Step-by-step explanation:

Find the height of the trapezoids

20 - 10 = 10

10/2 = 5

Find the area of the trapezoids

5*(20+10)/2 = 75

The formula for the area of the trapezoid is the height * the bases added together divided by 2

75*2(this is because there are 2 trapezoids) = 150

Put this to proportion of the total area of the dart board

150/20^{2} = 150/400 = 3/8

3/8 is the probability that you score 3 points

Use the fact that 2 1/2 divide 1/8 =20 to find 2 1/2 divide 5/8
Tasya [4]

Answer:

4

Step-by-step explanation:

Given that 2\frac 1 2 \div \frac 1 8 =20

\Rightarrow \frac 5 2 \div \frac 1 8 =20

\Rightarrow \frac 5 2 \times 8 1 =20 \cdots(i)

Now, 2\frac 1 2 \div \frac 5 8 = \frac 5 2 \div \frac 5 8=\frac 5 2 \times \frac 8 5

This can be written as

\frac 5 2 \times \frac 8 5=\frac 5 2 \times \left( \frac 8 1 \times \frac 1 5\right) [as \frac 8 5=\frac 8 1 \times \frac 1 5]

=\left(\frac 5 2 \times \frac 8 1 \right)\times \frac 1 5

=20 \times \frac 1 5 [ by using equation (i)]

=4

Hence, 2\frac 1 2 \div \frac 5 8=4
