I've done the first four questions. Use this method to answer the rest. For an odd number of objects find the cost of one and multiply by how many you are asked to find.
Two equivalent fractions equations are
r + 6
6 + r <span />
Now, if the diameter is 6 inches, then that means the radius is half that, or 3.
check the picture below.
Answer:
x=3
Step-by-step explanation:
2x+3=9 (subtract 3 from both sides)
2x=6 (divide both sides by 2)
x=3
Step-by-step explanation:
the ratio is 1:3:5, so we are talking about 1+3+5 = 9 parts or shares between them.
therefore, 1 share of 450,000 is
450,000/9 = 50,000
so, Anna gets R50,000.
Letty gets 3×50,000 = R150,000.
and finally Emily gets 5×50,000 = R250,000.
