Answer:
x = 4
Step-by-step explanation:
9(x - 2) = 18
9x - 18 = 18
9x = 18 + 18
9x = 36
x = 36/9
x = 4
Answer:
d) 5 lollipops each and 3 left over
Step-by-step explanation:
To find out how many each of them get, you need to find the total amount of lollipops to be shared equally.
Total No. of lollipops = 3 + 5 + 7 + 4 + 9
= 28
No. of lollipops each of them get = 28 ÷ 5
= 5 R3
(To find the remainder of something, you have to know how much is the quotient (which is 5 in this case), multiply it by the divisor (which is also 5 in this case) then minus that number from the total (which is 28 in this case) )
Additional working:
5 × 5 = 25
28 - 25 = 3 (remainder)

Answer:
"principal root"
Step-by-step explanation:
The positive (even or odd) root of a positive real number is called its <em>principal root</em>.
__
When an odd root is taken of a negative real number, the negative real root is the principal root. That is -2 is the principal cube root of -8.
The perimeter of one square is 20 cm.
explanation: since the rectangle can be divided into two squares, we can conclude that the area of one square is 25 cm^2 because 50 / 2 = 25. the square root of 25 is 5, so one side length of the square is 5 cm. multiply that by 4 (because there’s 4 sides) and you get 20 cm.
