Answer:

  • 4.08 x 10^2 = 408
  • 0.97 x 10^2 = 97

Step-by-step explanation:

Multiplying by 10^n moves the decimal point n places to the right. The expressions will be true for a multiplier of 10^2 if the final position of the decimal point is 2 places to the right of the initial position.

  0.031 x 10^3 = 31

  0.501 x 10^3 = 501

  4.08 x 10^2 = 408

  0.97 x 10^2 = 97

  0.55 x 10^3 = 550

Helen [10]

Answer:

x+4=20 is a solution to 5(x+4)=100.

Step-by-step explanation:

Following PEMDAS, divide 5 from both sides of the equation 5(x+4)=100, and you have x+4=20 remaining.

This means that both equations have the same solution.

Divide. Write the quotient in lowest terms. 1/4 ÷ 1 1/8<br><br> ​
natta225 [31]

Answer:2/11

Step-by-step explanation:

A fraction is in simplest form when the top and bottom cannot be any smaller

Firstly start by getting the common factors between 1 and 4 in 1/4 and 11 and 8 in 11/8. The common factor is 1 in 1/4 and 1 in 11/8. 1÷1/4÷1= 1/4. 11÷1/8÷1 = 11/8.

1/4÷ 11/8 =2/11.
