Answer:

16 and 8

Step-by-step explanation:

absolute value equations you have to make two problems and solve them:

first problem : x-12 =4  add 12 to both sides to get x by itself

so x = 12+4 so x is 16

second problem: x-12 = -4  add 12 to both sides to get x by itself

x = -4 + 12 so x is 8

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adult
amid [387]

Answer:

Number of children = 386

Number of adults = 287

Step-by-step explanation:

Let

x = number of children

y = number of adults

x + y = 673 (1)

1.75x + 2y = 1249.50 (2)

From (1)

x = 673 - y

Substitute x = 673 - y into (2)

1.75x + 2y = 1249.50

1.75(673 - y) + 2y = 1249.50

1177.75 - 1.75y + 2y = 1249.50

- 1.75y + 2y = 1249.50 - 1177.75

0.25y = 71.75

y = 71.75/0.25

y = 287

Substitute y = 287 into (1)

x + y = 673

x + 287 = 673

x = 673 - 287

x = 386

Number of children = 386

Number of adults = 287

How can you use doubles when multiplying with 4 to find 4x8
pshichka [43]
4 = 2 * 2

Multiplying by 2 is the same a doubling.
Since 4 is 2 * 2, to multiply a number by 4, double the number twice.

Example:
What is 4 * 100?
Double 100 to get 200.
Double 200 to get 400.
Therefore, 4 * 100 = 400.
By doubling twice, we do the same as multiplying by 4.

Is the product of 3√ and 2.8 is a rational number acquisition?
svetlana [45]

Answer:

It is not rational

Step-by-step explanation:

Given

\sqrt 3 * 2.8

Required

Rational or Irrational

\sqrt 3 * 2.8

\sqrt 3 =1.73205

So, we have:

\sqrt 3 * 2.8 = 1.73205 * 2.8

\sqrt 3 * 2.8 = 4.84974

<em>The result of the product: 4.84974  is not rational because it can not be represented as a fraction of two integers.</em>
