Answer:

You are 25

Step-by-step explanation:

This problem is a word problem that requires algebra notation, actually, we are meant to convert this word problem to mathematical expression then solve.

We proceed in a stepwise manner

let say what I have is x

1. Subtract 5 from me

  (x-5)

2. Then add 2

    (x-5)+2

3.  If you subtract 10

      (x-5)+2-10

4.  And then add 3

    (x-5)+2-10+3

5.  you get 15

   (x-5)+2-10+3=15

what am I is the question we need to answer, we do this by solving for x

x-5+2-10+3=15

x-15+5=15

x-10=15

x=15+10

x=25

Hi. This is is how it goes tep by step.



Cut the rectangle/shape the way you feel more comfortable. However, you don't know so I will recommend you cut it in half from where the 12 is. so now the 12 ft would be broken in to 2. the top section would be 45 ft because 5 times 9 is 45. the bottom would be 98 because 7 time 14 is 98. the total would be 143. for the first one.

Solve the literal equation for x.<br> y=5x-rx-5
Alchen [17]

Answer:

x = \frac{y+5}{(5-r)}

Step-by-step explanation:

Given the literal equation, y = 5x - rx - 5,

In order to solve for x, start by adding 5 on both sides of the equation:

y + 5 = 5x - rx - 5 + 5

y + 5 = 5x - rx

Next, factor out x from the right-hand side of the equation:

y + 5 = x(5 - r)

Finally, divide both sides by (5 - r) to isolate x:

\frac{y+5}{(5-r)} =  \frac{x(5 - r)}{(5-r)}

\frac{y+5}{(5-r)} =  x

The sum of two numbers is 262. The difference of those same two numbers is 172. Which answer choice shows both numbers?
STatiana [176]

Answer:

A = 217

B = 45

Step-by-step explanation:

A+B = 262

A - B = 172

A = 172 + B

172 + B + B = 262

2B = 90

B = 45

A = 172 + (45)

A = 217

HOPE THIS HELPS!!!!
