Step by step explanation on how to solve (-3 + 8 x 2 -3)

10

Step-by-step explanation:

You have to use PEMDAS

(-3 + 8 x 2 -3)     First, multiply

-3+16-3               Then, do it all in a row

10

x = 6

Step-by-step explanation:

-4

Step-by-step explanation:

-22-(6)(-9)/3

Multiply what is in the parentheses first.

6*-9= -54

Divide -54 by 3

-54/3= -18

-22-(-18)

= -4

-4

Step-by-step explanation:

-22-(6)(-9)/3

my bad it shows explanation

1/2 or 0.5

Step-by-step explanation:

   -24x - 15    = -27

-24x - 15 + 15 = -27 + 15

       -24x       = -12

          x          = 1/2 or 0.5

Here is a picture of my work. I thought it would be too tedious to type it up. I hope this helps you!! Have a great rest of your day.

x = 47

y = 94

Step-by-step explanation:

We know that one number is half another number and the sum of these two numbers is 141. We are to find the numbers.

Assuming [tex]x[/tex] and [tex]y[/tex] to be the numbers, we can write it as:

[tex]x=\frac{1}{2}y[/tex] --- (1)

[tex]x+y=141[/tex] --- (2)

Substituting the value of [tex]x[/tex] from (1) into (2) to get:

[tex]\frac{1}{2}y+y=141[/tex]

[tex]\frac{3}{2}y+y=141[/tex]

[tex]y=141 \times \frac{2}{3}[/tex]

y = 94

Now substituting this value of [tex]y[/tex] in (1):

[tex]x=\frac{1}{2} \times 94[/tex]

x = 47

Translating it in other words:

One number is double the other number and the sum of the two number is 141.

Checking answers:

[tex]x=\frac{1}{2}y[/tex]

[tex]47=\frac{1}{2} \times 94[/tex]

[tex]47=47[/tex]

[tex]x+y=141[/tex]

[tex]47+94=141[/tex]

Are (x= -2y -1) and (4x - 4y=20) two different problems or..?

Factor out variable x

X(s+t)=r

Divide both sides by s+t

The answer is x=r over s + t

Step-by-step explanation:

We need to find the volume

The volume of a cylinder is

V = pi r^2h

V = 3.14 * (5)^2 * 7

V =549.5

We want to put in 500 in^3

500 < 549.5 so the cat litter will fit

the answer is  

a.

4,624π mm2
