It's answer a y=x^2
multiple each number twice
4•4 16
2•2 4
3•3 9
Answer:
The number is 0.2
Step-by-step explanation:
Write an equation for it:
Say that the number was called x
2(x +8) =16.4
Brain added 8 to the number (x) and then doubled it which is the 2
Times out the brackets 2x + 16 = 16.4
Take away 16 from both sides
2x = 0.4
0.4 / 2 = 0.2
The least common multiple of 25 and 15 is 75. You'd do _ x 25 = 75 and _ x 15 = 75. The answer would be 3 and 5, so 5 packs of coins and 3 packs of coin holders.

Answer:
x=5
Step-by-step explanation:
Since the triangles are similar we can use ratios to solve
4.5 7.5
---- = ------
3 x
Using cross products
4.5x = 3 * 7.5
4.5x = 22.5
Divide each side by 4.5
x = 22.5/4.5
x=5
