Answer:
22
Step-by-step explanation:
square root of a number multiple by the himself give you the value
so square root of 22 x 22 = 22
The equation for r in the distance formula is r = d/t
Let x= the number of books purchased: 7 books purchased
let y = the number of toys purchased;10 toys purchased
Equations: x+y=17
6x+11y=152 x+10=17
-6(x+y=17) y=10 -10 -10
------------
-6x-6y=-102 x=7
6x+11y=152
--------------------
0x+5y=50
---- ----
5 5
5x-22=-7
Move -22 to the other side
Sign changes from-22 to +22
5x-22+22=-7+22
5x=-7+22
5x= 15
Divide both sides by 5 to get x by itself
5x/5= 15/5
x= 3
answer:
x= 3
6(10)-21
60-21
39 is the answer.
