Answer:

Step-by-step explanation:

To find x, set both equations equal to each other.

$\sqrt{x} = \sqrt{5x - 4}$

$( { \sqrt{x} })^{2} = ({ \sqrt{5x - 4} })^{2}$

$x = 5x - 4$

$x - 5x = 5x - 5x - 4$

$- 4x = - 4$

$- 4x \div - 4 = - 4 \div - 4$

$x = 1$

Answer:

23 gallons of water

Step-by-step explanation:

People use water to cook, clean, and drink every day. An estimate of 33.9% of the water used each day is for cooking. If a family uses 67.8 gallons of water a day for cooking, how many gallons do they use every day?

This is calculated as:

33.9 % × 67.8 gallons of water

= 0.339 × 67.8 gallons of water

= 22.9842 gallons of water

Approximately = 23 gallons of water

Therefore, 23 gallons of water are used everyday for cooking

jeka94

Answer: 3253

Step-by-step explanation:

Given : A test requires that you answer either part A or part B.

Part A consists of 7 true-false questions.

i.e. there are 2 choices to answer each question.

Now, the number of ways to answer Part A : $2^7=128$ (1)

Part B consists of 5 multiple-choice questions with one correct answer out of five.

i.e. there are 5 choices to answer each question.

Now, the number of ways to answer Part B : $5^5=3125$ (2)

Now, the number of different ways to completed answer sheets are possible= $128+3125=3253$ [Add (1) and (2) ]
