What number replaces the ◊?
15 = 15
15 + 4 + ◊ = 15 + 7

a. 3

b.4

c.19

d. 22

A. 3

First, simplify the equation. (x means the same thing as the symbol)

19 + x = 22

Subtract 19 from both sides of the equation.

x = 22 - 19

x = 3

There’s the answer!

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
