Given:
20 ounces of water
someone finishes 55% of water
What is left?
20 × 0.55 (55% =
= 0.55)
11
20 - 11 = 9
There are 9 ounces of water left
Answer:
The two numbers are 24 and 32
Step-by-step explanation:
We can use the variable x
3x : 4x, would be a ratio of 3/4
now subtract 4 from both
3x - 4 : 4x - 4 = 5/7
3x-4 / 4x-4 = 5/7
cross multiplication
7(3x - 4) = 5(4x - 4)
21x - 28 = 20x - 20
x = 8
Two numbers are;
3x, 4x
3(8), 4(8)
24, 32
24/32 = 3/4
20/28 = 5/7
She stopped because:
| 2 x - 0.6 | ≠ -2 . It is absolute value and it can´t be equal to the negative number.
This equation has no solution.
we know that
The scale factor is equal to
we have
substitute
therefore
<u>the answer is</u>
Answer:
1/8
Step-by-step explanation:
5 green marbles
40 marbles in total
so 5/40
And that simplifies to 1/8
