Jane is saving money to buy a game. The game costs $20, and so far she has saved four-fifths of this cost. How much money has Jane saved?

Answer:

-9

Step-by-step explanation:

5(-9-4)

5(-13)

-65

4(-9+15)

4(6)

24

-65<24 so -9 is false because -65 is not smaller than 24

The solution is Option A.

The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is given by

5 ( n − 4 ) < 4 ( n + 15 )

Now , on substituting the value of n as 80 in the inequality equation , we get

5 ( n − 4 ) < 4 ( n + 15 )

when n = 80

5 ( 80 - 4 ) < 4 ( 80 + 15 )

5 ( 76 ) < 4 ( 95 )

380 = 380

So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80

Hence ,

The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

Answer:

Just multiply 60 by 6 then add 12

:)

Step-by-step explanation:

First, you need to make the divisor a whole number, and then you make the dividend a whole number.

1.) 0.0056 divided by 0.004 = (0.0056 x 1000) x (0.004 x 1000)

You should make it a whole number by multiplying it by a power of ten.

2.) *5.6 divided by 4

Then divide.

3.) Answer : 0.0056 divided by 0.004 = 1.4

Answer: the answer is 14

Step-by-step explanation:0.056/- 0.004 as a percent value (as a percentage)

Detailed calculations below

Fractions: brief introduction

A fraction consists of two numbers and the fraction bar:

0.056/- 0.004

The number above the fraction bar is the numerator: 0.056

The number under the fraction bar is the denominator: - 0.004

To get the fraction's value, divide the numerator by the denominator:

The value = 0.056 ÷ - 0.004

Percent, p%: short introduction

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

How to convert a fraction to a percentage:

1) Calculate the value of the fraction.

2) Multiply this number by 100.

3) Add the percent sign %

Convert the fraction to a percentage

1. Calculate the value of the fraction.

To get the fraction's value, divide the numerator by the denominator:

0.056/- 0.004 =

0.056 ÷ - 0.004 =

- 14

A quick note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100

... and its value doesn't change.

n × 100/100 = n × 1 = n, any number n

2. The calculation of the percentage:

- 14 =

- 14 × 100/100 =

(- 14 × 100)/100 =

Answer:

That is the answer I got

Answer:

3. The first one.

4. The last one.

Step-by-step explanation:

For 3, first I looked to see what direction the greater than symbol was facing. Since it is pointing right, I know the arrow has to go right on the number line. Then, since it's only a greater than symbol, the dot is empty.

For 4, I used the same method as stated above. Greater than symbol means arrow goes to the right. However, since this symbol has a line underneath it, it is a greater than OR equal to symbol. This means the dot will be solid instead of empty.

Answer:

Step-by-step explanation: Part 1= 0.2(2)+79=79.4

Barry is given 0.4 and 0.9 cents

He already has 6.30 in his bank

0.4+0.9 = 1.3

add the money he was given to the bank

1.3 + 6.3 = $7.60

Barry has $7.60 in total.

Henry buys two candy bars, one is worth 3.20 and the other is 1.60

add them up to get the total

3.20 + 1.60 = 4.80

Henry has $8.50

subtract the cost of the chocolate from the money he has

8.50 - 4.80 = $3.70

Henry has $3.70 left over from the $8.50

Beth buys a bouncy ball worth 1.20 and pen that is 5 times that amount.

this put into an equation is

1.20 + (5*1.20) =

1.20 + 6 =

$7.20

The bouncy ball and pen cost $7.20 in total.

Joe found 1 dollar ($1), 4 quarters ($1), and 3 dimes ($0.30) on Monday

In total that is,

1 + 1 + 0.30 = $2.30

He found $2.30 on monday

On tuesday, he finds 3 times that amount

3 * 2.30 = $6.90

He found $6.90 on tuesday

add them up and you get

2.30 + 6.90 =

$9.20

Joe found $9.20 on Monday and Tuesday combined.

Answer:

1. $7.60

2. $3.70

3. $7.20

4. $5.20

Step-by-step explanation:

1. 0.40+0.90+6.30= 7.60

2. 8.50-(3.20+1.60)=3.70

3. 1.20+(1.20*5)= 7.20

4. (1+1+0.30)+(1+1+0.30*3)= 5.20

Answer:

-2/3

Step-by-step explanation:

You are looking the change in y over  the change in x.

for y, if you go from -5 to -7, how much did it change?  -2

-7 -(-5) = -7 + 5 = -2

Now look the the x's.  If you from 6 to 9 how much did you change?

3

9-6 = 3

-2/3

Answer:

-2/3

Step-by-step explanation:

A slope is [tex]\frac{Change in Y}{Change in X}[/tex] and we can see that when the x value increases by 3, the y value decreases by 2. So if we plug that in, we get -2 for the Change in Y and +3 for the Change in X. Which results in the slope being [tex]-\frac{2}{3}[/tex]

Answer:

27.2

Step-by-step explanation:

9cm = 16ft

It's asking about length (L) so the room is 15.3cm long. We can ignore the width, 5 cm.

Set up a ratio. [tex]\frac{9cm}{16ft} =\frac{15.3cm}{L}[/tex]

Cross-multiply. 9*L = 15.3*16

Solve for L. L = (15.3*16)/9 = 27.2ft

Step-by-step explanation:

Point 1: (-6, 6); Point 2: (6, 2)

m = ------------ = ----------- = ---------- = -------------- = -------

        x₂ - x₁        6 - (-6)      6 + 6        12 ÷ 4           3

y - y₁ = m(x - x₁)

y - 6 = (-1/3)(x + 6)

y - 6 = (-1/3)x - 2

Answer:

The change in altitude per minute is 63.5 alt/ min

What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

In 24 minutes = 1524 feet

So, the average Change in altitude per minute

=1524/24

= 63.5 alt/ min

hence, change in altitude per minute is 63.5 alt/ min.

Answer:

Slope = (3/5)

Step-by-step explanation:

Point 1: (5, 3); Point 2: (10, 6)

            (x₁, y₁)               (x₂, y₂)

       y₂ - y₁        6 - 3           3

m = ----------- = ----------- = ---------

       x₂ - x₁        10 - 5          5

y - y₁ = m(x - x₁)

y - 3 = (3/5)(x - 5)

y - 3 = (3/5)x - 3

  +3               +3

-----------------------------

y = (3/5)x

Answer:

8/15 or .53

Step-by-step explanation:

Here, we need to apply basic mathematical operations and solve the given linear equation. We get the value of a = -4.

Linear equations are expressions that involve variables and constants raised to the power of 1 (i.e., the exponent is 1) and are represented as a straight line when graphed on a coordinate 2D axis. A linear equation can be written in the form ax+ b = c where x is a variable and a,b, and c are constants .

Linear equations can have one variable (univariate) or multiple variables (multivariate). Also, these variables should not be squared, cubed, or raised to the power of any constant other than 1. For example,

1. 2x+5=0 (univariate)

2. 4z+2w=5x(multivariate)

The question given to us is an univariate linear equation where to have to apply basic rules of mathematics. Firstly we need to divide 56 by 14 which gives us 4. The negative sign gives our answer as -4.
