Cd+e = 21    Equation

Cd + e - e = 21 - e  Subtract \ e \ from \ both \ sides

Cd = 21 - e    Simplify

Cd/C = 21-e/C  Divide \ both \ sides \ by \ C


d = 21-e/C.  Solution

Cd+e = 21

Cd + e - e = 21 - e

Cd = 21 - e

Cd/C = 21-e/C

d = 21-e/C.

Pls help I don’t get it
Setler [38]

Answer:

x=-5, y=-2

Step-by-step explanation:

10x-9y=-32

2x-10y=10

(2x-10y)*5=10*5

10x-50y=50

(10x-9y)-(10x-50y)=-32-50

41y=-82

y=-82/2

y=-2

10x-9(-2)=-32

10x+18=-32

10x=-50

x=-5

Work out the length of AB.
4vir4ik [10]
\frac{AB}{BC}   =   \frac{EB}{DC}

\frac{AB}{BC}   =   \frac{1.75 m}{7 m}

let AB = E

⇒                 (AB) (7 m) = (1.75 m) ( BC + AB)
                    (AB) (7 m) = (1.75 m) (1.5 m + AB)
                                      =  2.625 m²  +  (1.75 m ) (AB)
      (AB) (7 m - 1.75 m) = 2.625 m² 
                            ∴  AB =  2.625 m²  ÷  (5.25 m)
                           
<span>                   ⇒ the length of AB is 0.5 m</span>

When you divide a whole number by a decimal less than 1, the quotient is greater than the whole number. Why?
KiRa [710]
Dividing is the action of slimming a number down to a smaller size. When you divide a whole number by a decimal less than 1 the quotient is greater than the whole number because the that is how many times the quotient is a part of the whole number. For instance, you divide 100 by 4, you will get a quotient of 25. There are 4 parts of 25 to be equal to 100.

I hope this helps you!
