Anne has 24 more cards than Devi. Anne finds that 3/5 of Devi's cards are equal to 1/2 of her cards. How many cards does Anne have?

Answers

LET ANNE HAS X NUMBER OF CARDS
LET DEVI HAS Y NUMBER OF CARDS
X-Y= 24 ------EQ 1
3/5Y=1/2X
6Y=5X (cross multiplying)-------EQ 2
FROM EQ 1 WE GET
X=24+Y
substituting the value of x in eq 2, we get
6y=5(24+y)
6y =120+5y
y= 120

NOW, PUTTING THE VALUE OF Y IN EQ 1
X-120=24
X=24+120
X=144
THEREFORE, ANNE HAS 144 CARDS

a=Anne's cards
D= Devi's cards
d+24=a
3d/5=a/2
6d/5=a
6d/5=d+24
6d/5-d=24
6d-5d=120
d=120
a=144

Is the function linear or nonlinear?
y=1/x

Answers

It's a nonlinear function.

The linear function is of the form $y=mx+b$

Answer:

The answer is nonlinear.

Step-by-step explanation:

y=mx+b

m is slope

b is y-intercept

y=1/x doesn't make any sense (to me anyway)

Bradley solved the following equation: 4(5x – 6) = 2(8x + 10) Step Work Justification 1 20x – 24 = 16x + 20 2 4x – 24 = 20 3 4x = 44 4 x = 11 Which of the following has all correct justifications Bradley used to solve this equation? 1. Associative property of addition. 2. Subtraction property of equality. 3. Addition property of equality. 4. Multiplicative inverse. 1. Associative property of addition. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality. 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Multiplicative property of equality. 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality.

Answers

Solution:

The equation solved by Bradley is

→4(5x – 6) = 2(8x + 10)

Step Work

1. 20 x – 24 = 16 x + 20 → [ Distributive property]

Taking variable on one side of equation

2 . 4 x – 24 = 20 → [Subtraction property of equality.]

Taking constant on one side of equation

3 . 4 x = 44 →[Addition property of equality.]

Dividing both sides by 4

4 . x = 11 → [Division property of equality.]

Out of all the four options given ,Fourth option [ 1. Distributive property. 2. Subtraction property of equality. 3. Addition property of equality. 4. Division property of equality ], completely satisfies the work done in equation.
