Answer:

5×(-4) = -20

(-1) × 4 = -4

Step-by-step explanation:

Here it' sayin when a positive number ( it may be odd or even ) gets multiplied with an even number ( it may be positive or negative ) , the product will be positive number.

5×(-4) = -20 .Here 5 is a positive number & 4 is a negative even number but the product -20 is a negative number. So it contradicts the statement.

(-1) × 4 = -4 . Here -1 is a negative number & 4 is a positive even number but the product -4 is a negative number. So it contradicts the statement.

Write the decimal shown by this point:+00 +10

const2013 [10]

When you count the small lines in between 8 and 9, there are 8 lines

The difference between 8 and 9 is 1

Divide 1 by 8, you will have 0.125

This implies each small lines represent 0.125

When you count from 8 to where the point is, we have 6 small lines

Multiply the 6 by 0.125, we will have 0.75

8 + 0.75 = 8.75

The decimal is 8.75

Answer:

(-11, -12)

Step-by-step explanation:

we need one variable to x out

on the note of x, lets cancel out the xs

6x+3y=-102

3x+y=-45 < same as 6x+2y-90

6x+3y=-102

6x+2y=-90

y=-12

substitute y in

3x-12=-45

3x=-33

x=-11

(-11, -12)

Celia has some cakes.

Vadim26 [7]

The carrot cakes are the fraction of the cake given by $1 - \frac{6}{7}$ multiplied by $\frac{1}{3}$

The fraction of the cakes that are carrot cakes is $\underline {\dfrac{1}{21}}$

<h3>How are the cakes evaluated as fractions?</h3>

The fraction of the cake that are chocolate cake = $\dfrac{2}{3}$

The fraction of the remaining cake that cheesecakes = $\dfrac{6}{7}$

The rest of the cakes = carrot cakes

Required:

The fraction of the cake that are carrot cakes

Solution:

The fraction of the cakes that are not chocolate cake = $1 - \dfrac{2}{3} = \mathbf{ \dfrac{1}{3}}$

The fraction of the remaining cakes that are cheesecake = $\dfrac{6}{7} \times \dfrac{1}{3} = \mathbf{ \dfrac{6}{21}}$

The fraction of the cake that are carrot cake = $\dfrac{1}{3} - \dfrac{6}{7} \times \dfrac{1}{3} = \mathbf{\dfrac{1}{21}}$

The fraction of the cakes that are carrot cake is $\underline{\dfrac{1}{21}}$
