Answer 1
Answer: With 10 to the power to a negative number, it's easier. 
Here's a trick: The negative number is the places to the right of the decimal. The last number is a 1, while the rest are 0s.

From this, we get: 10^(-4)=\boxed{0.0001}
Answer 2
Answer: 10^4 = 10000 (four zeros at the end)
10^-4 = 0.0001 (four zeros at the front)

How to solve 5x-2y=3 y=2x

Answers

If y = 2x, you simply need to replace y with 2x, and then solve the equation normally. 

5x –2(y) = 3
5x – 2(2x) = 3
5x – 4x = 3
x = 3

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Given that, in a survey, 35 out of 75 students buy a school lunch on Fridays.

35/75

There are 600 students in the school.

Here, 600/75

= 8

Now, 35×8

= 280

Therefore, the cafeteria manager predicted number of students come for lunch at school each Friday is 280.

A family pass to the amusement park costs $54 Using the Distributive Property,write an expression that can be used to fine the cost in dollars of 8 family passes

Answers

The cost in dollars of 8 family passes will be $432.

What is Distributive property?

By the rule of distributive property, multiplying the sum of two or more addends by a number gives the same result as when each addend is multiplied individually by the number and the products are added together.

Given that;

A family pass to the amusement park costs = $54

Now,

Using the Distributive Property,

Cost of 8 family pass = 8 × 54

                                = 8 × (50 + 4)

                                = 8 × 50 + 8 × 4

                                = 400 + 32

                                = 432

Thus, The cost in dollars of 8 family passes will be $432.

The distributive property is: a(b + c) = ab + ac. In this expression, the example would be 8(54 + 0) = (8 x 54) + (8 x 0). The cost of eight family passes is therefore equal to 8 x 54. $432 is the answer.

8 - 1/3x=16

Answers

Answer:

- 24

Step-by-step explanation:

Step 1:

8 - 1/3x = 16      Equation

Step 2:

- 1/3x = 8     Subtract 8 on both sides

Step 3:

x = 8 ÷ - 1/3    Divide

Step 4:

x = 8 × - 3      Multiply

Answer:

x = - 24

Hope This Helps :)

The solution to the equation 8 - (1/3)x = 16 is x = -24.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Given equation 8 - (1/3)x = 16

1. Begin by isolating the term with the variable, (1/3)x,

by subtracting 8 from both sides of the equation:

8 - 8 - (1/3)x = 16 - 8

-(1/3)x = 8

2. Next, multiply both sides of the equation by -3 to eliminate the fraction:

-3 * (-(1/3)x) = -3 * 8

x = -24

Therefore, the solution is x = -24.
