Answer: x = 20
Explanation:
What we have to solve is:
we should multiply both sides by10, to get the "x" by itself:
so there are 8 tenths in this number!
Answer:
Therefore, the possible lengths (in whole inches) for the third side is
9 inches < x < 45 inches
Step-by-step explanation:
For the above question, we have a rule, the sum of the length of any two sides of the triangle must be greater than the length of the third side.
Hence:
She has two sides of length 18 inches and 27 inches
Let the third side = x
Hence:
a) 18 + 27 > x
45 > x
b) 18 + x > 27
x > 27 - 18
x > 9
Therefore, the possible lengths (in whole inches) for the third side is
9 inches < x < 45 inches
Answer: 46 puzzles
Step-by-step explanation:
There are 70 puzzles in total in the book.
Jackie has completed / of those puzzles. In whole numbers that is:
= 2 /5 * 70
= 28 puzzles
She then completes 18 more puzzles.
Total that she has completed is:
= 28 + 18
= 46 puzzles
