Jackie won tickets playing the bowling game at the local arcade. The first time, she won 60 tickets. The second time, she won a bonus, which was 4 times the number of tickets of the second prize. Altogether she won 200 tickets. How many tickets was the second prize?

Answers

28 is the number of tickets of the second prize

How to calculate how many tickets the second prize is?

A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation

Given that:

The first time wins = 60 tickets

The second time, she won a bonus, which was 4 times the number of tickets of the second prize

Altogether she won 200 tickets

Let N represent the number of tickets of the second prize

This can be written as:

60 + N + (4×N) = 200

60 + N + 4N = 200

60 + 5N = 200

5N = 200 -60

5N = 140

N = 140/5

N = 28

Therefore, the number of tickets of the second prize is 28

john swims 5/12 of a mile in 3/8 of an hour. What distance, in miles, does john swims in an hour?

A.) 1 5/9
B.)15/96
C.)5/20
D.)1 5/12​

Answers

Answer:

1 1/9 miles

Step-by-step explanation:

If john swims 5/12 of a mile in 3/8 of an hour, then;

5/12 miles = 3/8 hours

TO get the number of miles he swims in an hour, we will say;

x miles = 1 hour

Equating both expressions

5/12 miles = 3/8 hours

x miles = 1 hour

Cross multiply

3/8 x = 5/12

3x/8 = 5/12

3x * 12 = 5 * 8

36x = 40

x = 40/36

x = 10/9

x = 1 1/9

The amount he swims in an hour is 1 1/9 miles

2.Y = 5x and y = 5x - 1
3. 2x + y = 1 and 2y + 4x = 2
4. Y = 2x + 3 and y = -x - 4​

Answers

Answer:

1.Perpendicular

2. Parallel

3. Parallel

4.

Step-by-step explanation:

If two lines are parallel, slope is equal

If perpendicular, product of slopes is -1

y = mx + c is the general equation of a line form

m represents slope

1. slope is -1 and 1, they are perpendicular

2. Slope is 5 in both cases, they are parallel

3. slope is equal; equation ii is same as i if rewritten

They are parallel

Q1. Solve the linear equation
a) y - 3 = -5​

Answers

Greetings.

The answer is y = -2.

Explanation:

The equation is defined to solve for y-term. Our y is currently our subject at this point and needs to be solved.

We move -3 to another side and leave y as the subject of equation. Moving to another side will change the sign/operator to opposite.

Plus ---> Minus

Minus ---> Plus

Multiply ---> Divide

Answers

Answer:

See below

Step-by-step explanation:

Uber$5 pickup fee$0.25 per mile

Equation

y = 0.25x + 5

Cost of 5 miles:

y = 0.25(5) + 5 = $6.25KC yellow Cab Co.$1.75 pickup fee$0.75 per mile

Equation

y = 0.75x + 1.75

Cost of 5 miles:

y = 0.75(5) + 1.75 = $5.5

Comparing the cost we see KC yellow Cab Co. is better value for a 5 mile ride.

Answers

Answer:

1.43

0.06

0.005

0.019

0.0075

Step-by-step explanation:

143% = 143/100 = 1 whole 43/100 = 1.43

6% = 6/100 = 3/50 = 0.06

1/2% = 0.5% = 0.5/100 = 1/200 = 0.005

1.9% = 1.9/100 = 19/1000 = 0.019

3/4% = 0.75/100 = 75/10000 = 3/400 = 0.0075

Answers

Answer:

y = 4x - 16

Step-by-step explanation:

Plug in the slope and point into y = mx + b, and solve for b:

y = mx + b

-8 = 4(2) + b

-8 = 8 + b

-16 = b

Then, plug in b and the slope into y = mx + b

y = 4x - 16 is the equation in point slope form
