400% • x = 1
400/100 • x = 1
4x = 1
Divide each side by four.
4x/4 = ¼
x = ¼

The value of x is ¼.

Since 400% is essentially 4 times as much of something, this is $4x = 1$ . Therefore, $x = \frac{1}{4}$

Answer:

x = 59

Step-by-step explanation:

So first lets distribute;

29 + x - 24 = 64

Collect like terms;

What percent of $5x$ is equal to $x/5$?

amm1812

Answer:

Step-by-step explanation:

Let y% of 5x is equal to $\frac{x}{5}.$

$y\% \: of \: 5x = \frac{x}{5} \\ \\ \therefore \: \frac{y}{100} \times 5x = \frac{x}{5} \\ \\ \therefore \: y = \frac{x}{5 \times 5x} \times 100 \\ \\ \therefore \: y = \frac{1}{25} \times 100 \\ \\ \therefore \: y = 4 \\ \\ \therefore \: 4\% \: of \: 5x \: is \: equal \: to \: \frac{x}{5}$

Lynn bought a bag of grapefruit 1 5/8 pounds of apples to + 3/16 pounds of bananas the total weight of her purchase with 7 1/2 p

Irina-Kira [14]

Let us assume the weight of grapefruit = x pounds
Weight of the apples = 1 5/8 pounds
= 13/8 pounds
Weight of the bananas = 3/16 pounds
The total weight of her purchase = 7 1/2 pounds
= 15/2 pounds
Then we get the equation as
x + 13/8 + 3/16 = 15/2
16x + 26 + 3 = 16 * (15/2)
16x + 29 = 8 * 15
16x + 29 = 120
16x = 120 - 29
16x = 91
x = 91/16
So the weight of the grapefruit is 91/16 pounds. It can also be written
as 5 11/16 pounds
