Together, Tim and Tom have $2.40. Tim has three times as much as Tom. How much does each have?
Phoenix [80]
X = how much Tim has
y = how much Tom has
x + y = 2.40
x = 3y
Substitute 3y for x
3y + y = 2.40
4y = 2.40
y = 0.60
Plug in y value into previous equation
x = 3(0.60)
x = 1.80

Let a=3/4 and b=1/5. If a*x=b, then what is x?
Anarel [89]

In general, any equation like ax=b (assuming a \neq 0) is solved by

x= \dfrac{b}{a}

So, in your case, the solution is

x = \dfrac{\frac{1}{5}}{\frac{3}{4}}

Dividing by a fraction means to multiply by the inverse of that fraction:

\dfrac{\frac{1}{5}}{\frac{3}{4}} = \dfrac{1}{5} \cdot \dfrac{4}{3} = \dfrac{4}{15}

Karen will divide her garden into equal parts. She will plant corn in 8/20 of the garden what is the fewest number of parts she
gayaneshka [121]

Answer:

5

Step-by-step explanation:

We know that Karen divided her garden into equal parts of which she intend to plant corn in ⁸/20 of it.

This implies that she divide the garden was divided into 20 parts.

To determine the fewer number of parts she can divide her garden into, simply ⁸/20.

Thus:

8/20 = (2*4)/(5*4)

= ²/5 (4 cancels out 4)

Therefore, this implies that the least number of parts she can divide her garden into is 5.
