Answer:

1/2+1/5=7/10

Step-by-step explanation:

1/2=5/10

1/5=2/10

2/10+5/10=7/10

Answer:

0.7 or 7/10

Step-by-step explanation:

When adding fractions they always need to have the same denominators,and the one they both have similar to is being equal to 10.

1/2 will get multiply with 5 on the numinator and the denominator having you get a fraction of 5/10.

You will do the same with 1/5 multiply it with 2 on the numinator and denominator having you get  5/10.

Since the dneominators are the same you keep it 10,and just add 5 and 2. Giving you a answer of 7/10

Answer:

x = 5

Step-by-step explanation:

The information given has been sketched out in the attachment below.

Line segment EJ is an angle bisector of angle DEF. Therefore, m<DEJ = m<JEF.

The equation to find x would be expressed as follows:

5x + 7 = 8x - 8

Subtract 5x from each side (subtraction property of equality)

5x + 7 - 5x = 8x - 8 - 5x

5x - 5x + 7 = 8x - 5x - 8

0 + 7 = 3x - 8

7 = 3x - 8

Add 8 to both sides of the equation (addition property of equality)

7 + 8 = 3x - 8 + 8

15 = 3x

Divide both sides by 3

15/3 = 3x/3

5 = x

x = 5

Answer:

a · b  = 28 units

Step-by-step explanation:

Given vectors

a = (-5, 1/2)

b = (-5, 6)

The scalar or dot product of the two vectors, given by a · b is

a · b  = (-5, 1/2) · (-5, 6)

To solve this, multiply the first term in a with the first term in b and add the result to the product of the second term in a and the second term in b. i.e

a · b  = (-5 x -5) +  (1/2 x 6)

a · b  = 25 + 3

a · b  = 28

Therefore, the dot product of a and b is

a · b  = 28 units

Answer:

h(-67) = 3158

Step-by-step explanation:

Simply plug in -67 for x:

h(-67) = -49(-67) - 125

h(-67) = 3283 - 125

h(-67) = 3158

Answer: h(-67) = 3158

Step-by-step explanation:

-49(-67)-125

3283-125

Answer:

7 + 2 × a.

Step-by-step explanation:

Take a as the number.

Twice the number means 2 multiplied by the number.

More than means addition.

So, it would be 7 + 2 × a.

It's an equation.

Complete question:

A book shop sold fiction books and cartoon books at a ratio of 3:5. Then, it sold four times as many fiction books and 40% more cartoon books. As a result, it sold 800 more fiction books than cartoon books. How many fiction and cartoon books were sold altogether in the end?

Answer:

3040

Step-by-step explanation:

Given the following :

Sales ratio = 3:5 (fiction : cartoon)

Let total number of books sold = x

Fiction books = 3x

Cartoon books = 5x

Four times as many fiction books = 4 × fiction books = 4*(3x) = 12x - - - (1)

40% more cartoon books = 40/100 = 0.4

5x(1.40) = 7x - - - (2)

As a result, 800 more fiction books than cartoon :

Fiction - cartoon = 800

12x - 7x = 800

5x = 800

x = 160

Substitute x into (1) and (2)

Fiction books : 12(160) = 1920

Cartoon books : 7(160) = 1120

1920 + 1120 = 3,040

Answer:

Step-by-step explanation:

n is the number of sides of the polygon

[tex](n - 2) \times 180 = 900[/tex]

Divide both sides of the equation by 180

[tex] \frac{(n - 2) \times 180}{180} = \frac{900}{180} \\ n - 2 = 5 \\ n = 5 + 2 \\ n = 7[/tex]
