Tina solved an equation incorrectly, as shown below:Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16

Which statement best explains why Step 2 is incorrect in Tina's solution?

She did not divide 24 by 8.
She did not add 8 to 24.
She did not multiply 24 by 8.
She did not multiply 24 eight times

Answers

Step 1: 8x = 24
Step 2: x = 24 − 8
Step 3: x = 16

Step 2 should be: x = 24 / 8
Step 3 would result to: x = 3

She did not divide 24 by 8.

Simplify the expression below.
√169

Answers

Answer:

The simplified form of the given expression is 13.

Step-by-step explanation:

The given expression is

$√(169)$

It can be written as

$√(13* 13)$

$√(13^2)$

$(13^2)^{(1)/(2)}$ $[\because √(x)=x^{(1)/(2)}]$

$13^{(2)/(2)}$ $[\because (x^m)^n=x^(mn)]$

$13^(1)$

$13$

Therefore the simplified form of the given expression is 13.

The square root of 169 is 13 because 13X13 equals to 169.

At Billy's preschool, they have a total of 25 bicycles and tricycles. Among them all, there are 57 wheels. How many of each are there?

Answers

let x be the number of bicycles and y the number of tricycles. x+y=25 (1) and 2x+3y=57 (2). Multiplying (1) by 2, you have 2x+2y=50. Doing (2)-(1) gives y=7. Therefore, x=25-7=18. There are 18 bicycles and 7 tricycles.
