Answer:
60 books
Step-by-step explanation:
let the number of books Willy has be x , then
Tammy has 4x books
Willy has 180 fewer books , that is Tammy has 180 more than Willy , so
4x = x + 180 ( subtract x from both sides )
3x = 180 ( divide both sides by 3 )
x = 60
Thus
Willy has 60 books andTammy has 4 × 60 = 240 books
which is 180 more than Willy
I dont think the answer is always. Because integers are always whole numbers. Hope that helps a little?
Step-by-step explanation:
Hey there!
Given;
Ratio = 9:8:7
Let "x" be the common factor. So,
9x+8x+7x = 144
or, 24x = 144
or, x = 144/24
or, x= 6
It's like;
= 9*6:8*6:7*6
= 54:48:42
Therefore, their ratio is 54:48:42.

Answer:
31.5 units²
Step-by-step explanation:
Area = ½*base*height
Height of the triangle on the grid = 9 units
Base = 7 units
Area = ½*9*7
Area = ½*63
Area = 63/2
Area = 31.5 units²
