Answer:

2/11

Step-by-step explanation:

Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"

4 2/5 + k = -3 2/11

I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.

4 2/5 + k = -3 -2/11

k = - 3 - 4 - 2/5 - 2/11

k= - 7 -2/5 -2/11

Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.

k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)

k = - 385/55 - 22/55 -10/55

k = - (385 +22+10)/55

k = - 417/55

Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.

btw correct me if i am wrong

Answer:

[tex] k = - 1 \frac{12}{55} [/tex]

Step-by-step explanation:

[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]

Answer:

Store 1

Step-by-step explanation:

Given

See attachment

Required

Determine the store with the best price per unit

It should be noted that the store with the best has the least price per unit.

So, we have:

Store 1

[tex]Quantity = 10\ ft[/tex]

[tex]Price = \$2.50[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$2.50}{10\ ft}[/tex]

Rate = $0.250 per feet

Store 2

[tex]Quantity = 2\ yd[/tex]

[tex]Price = \$1.85[/tex]

Convert quantity to feet

[tex]Quantity = 2 * 3ft = 6ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$1.85}{6\ ft}[/tex]

Rate = $0.308 per feet

Store 3

[tex]Quantity = 12\ ft[/tex]

[tex]Price = \$3.40[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$3.40}{12\ ft}[/tex]

Rate = $0.283 per feet

Store 4

[tex]Quantity = 5\ yd[/tex]

[tex]Price = \$4.00[/tex]

Convert quantity to feet

[tex]Quantity = 5 * 3ft = 15ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$4.00}{15\ ft}[/tex]

Rate = $0.267 per feet

From the calculations above; store 1 has the least unit rate.

Hence, store 1 has the best price per unit

Answer:

89 km/hr

Step-by-step explanation:

Distance = Rate(speed) × Time

D = R × T

T = 4 hours

One car's rate is 12 kilometers per hour less than the other's.

Hence:

First's car's rate = r × 4 = 4r

Second car's distance = (r + 12) × 4 = 4r + 48

4r + 4r + 48 = 760

8r + 48 = 760

8r = 760 - 48

8r = 712

r = 712/8

r = 89 km/hr

The rate of the slower car is 89 km/hr

Step-by-step explanation:

Fred, Ben, and George bought a pizza. George's sister and her friends ate some of the pizza, they left 1/2 of the whole pizza. Fred decided that they should share the remaining pizza equally. How much of the pizza will they each get?

1/2 ÷ 3 = 1/6

The three boys will each get 1/6 of the pizza.

Step-by-step explanation:

for it to be a right triangle you should be able to add two of the sides and it be greater than the third side. 7 + 24 > 25

24 + 25 > 7

7 + 25 > 24 therefore it is indeed a right triangle

Answer:

[tex]y=2x[/tex]

Step-by-step explanation:

We want to write an equation in slope-intercept form that passes through the points (2, 4) and (3, 6).

So, we will first find the slope. Let (2, 4) be (x₁, y₁) an let (3, 6) be (x₂, y₂).

The slope formula is given by:

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

So, by substitution, our slope is:

[tex]\displaystyle m=\frac{6-4}{3-2}=\frac{2}{1}=2[/tex]

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

By substitution:

[tex]y-(4)=2(x-(2))[/tex]

Distribute:

[tex]y-4=2x-4[/tex]

Adding 4 to both sides yields:

[tex]y=2x[/tex]

And we have our equation.

In this case, the y-intercept is 0.

Answer:

1

Step-by-step explanation:

The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.

The coefficient  of z in the expression 3x- 4y +z is 1.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

3x - 4y + z

As, we know a coefficient is a number that is multiplied by a variable.

So, the coefficient of x is 3, coefficient of y is 4 and coefficient  of z is 1.

Answer:

[tex]Side_2 = 74\ in[/tex]

Step-by-step explanation:

Given

[tex]Side_1= 82\ in[/tex]

[tex]Area = 6068\ in^2[/tex]

Required

Determine the length of the other side

For a rectangle:

[tex]Area = Side_1 * Side_2[/tex]

This gives:

[tex]6068\ in^2 = 82\ in * Side_2[/tex]

Divide both sides by 82in

[tex]\frac{6068\ in^2}{82\ in} = \frac{82\ in}{82\ in} * Side_2[/tex]

[tex]\frac{6068\ in^2}{82\ in} = Side_2[/tex]

[tex]Side_2 = \frac{6068\ in^2}{82\ in}[/tex]

[tex]Side_2 = 74\ in[/tex]

Hence, the length of the other side is 74 inches

Answer:

S = 83 g and 650 kg.

Step-by-step explanation:

Gram (g)= 1000 kilograms (kg).

Jill (J)= 92000 + 250 kg.

J = 92250 kg

Sister (S) = J - (8000 + 600 kg)

S = 92250 - 8600 kg

S = 83650 kg.

S = 83 g and 650 kg.

The y intercept is 7 and the slope is

( 0,7) and (2,3)

m = ( 3-7)/( 2-0) = -4/2 = -2

Changing this to an inequality

y < -2x+7

Add 2x to each side
