Add that sum to 30.

B.
Multiply 30 × 2.
Subtract 10 from 30.
Add the product and the difference.
Add that sum to 30.

C.
Divide 30 by 2. Then add the quotient to 10.

D.
Multiply 30 × 2.
Add that product to 30.
Divide the sum by

Answer 1

Give a name to the durations "Run", "Walk", "ride Bike" : \(R,W,B\).
You are told \(W=30\).
- What is \(R\)?
- What is \(B\)?
- What is total exercise time?

Answer 2

Translate the statement into maths: `Kathie ran for twice as long as she walked.` -> \(R = 2W\).

Answer 3

So, it would be, 2 x 30?

Answer 4

Yes.

Answer 5

How do you translate `She walked for 10 minutes more than she rode her bike.` into maths ?

Answer 6

60

Answer 7

2 x 30 = 60

Answer 8

Just 10 x ?

Answer 9

Adoy.

Answer 10

I meant 10 x 60

Answer 11

`more` will translate to something an expression with the operation "+" or "-" .

Answer 12

Lemme write that down. Okay, got it.

Answer 13

@reemii

Answer 14

Are you there?

Answer 15

I am

Answer 16

I kinda lost connection there.

Answer 17

Fck this test is due half a hour.

Answer 18

\(X\) is ten more than \(Y\) translates to \(X=Y+10\).

How do you translate `She walked for 10 minutes more than she rode her bike.` in terms of \(R\) and \(B\)?

`She walked for 10 minutes more than she rode her bike.`= `Walk is ten more than Bike`.
etc. next step is to write the equation.

Answer 19

that will be \(W = B+10\). So, \(B=W-10=30-10\).

The total amount of time is \(W+B+R\).

Answer 20

Okay, I got the rest thanks!
