Ahmad travelled 1/4 of a journey by Train X, 3/4 of the remainder by Train Y and the remaining 10km by Train Z. a) How far did A

sveta [45]

Hey there! I'm happy to help!

Train X takes out 1/4 of our journey.

Now, we have 3/4 of the journey left.

Train Y takes 3/4 of the last 3/4 of the journey. How much is that, let's just multiply the fractions!

3/4*3/4= 9/16

So, 9/16 of the total journey is done by Train Y.

A fourth of 16/16 is 4/16, so that leaves us with 3/16 left to go.

So, 3/16 of our total distance is equal to 10 km. Let's call our total distance d and set this up as an equation.

3/16d=10

Divide both sides by 3/16.

d= 53 1/3

We also remember that Train Y gave us 9/16 of our total journey, so we can multiply this by our total distance to see how far train Y went.

53 1/3 * 9/16= 30

So, A. Ahmad traveled 30 miles by Train Y and B. his total distance traveled is 53 1/3 miles.

Have a wonderful day and keep on learning! :D

Mike scored 38 points in the first half of the basketball game, and he scored p points in the second half of the game. Write an

Vladimir [108]

38 + p

He scored 58 points total if she scored 20 in the second half

Adding up the number of the points earned in the first half (38) and the number of points earned in the second half (p) will give you the total points.

If he scored 20 points in the second half of the game, then you can change the expression to:

38 + 20

Because now you know what he scored in both the first half and the second half. Then you can add them together to get the answer of 58

Hi! So, I know I got this answer wrong, but I wasn't sure how to solve an equation with signs like: [brackets] in it, I've inclu

dimaraw [331]

Step-by-step explanation:

Brackets is the bigger version of parentheses, you first solve the questions inside the parentheses, then move onto brackets.

For example, this question:

$x=-1\\y=-2\\z=3$

$5x-y[7-4(z-y)]$

plug in x, y, and z.

$5(-1)-(-2)[7-4(3-(-2))]$
$5(-1)-(-2)[7-4(5)]$

$5(-1)-(-2)[7-20]$

$5(-1)-(-2)[-13]$

$-5-(-2)[-13]$

$-5-26$

$-31$

I hope you understand better now.
