Answer:

46p + 31

hope it's helpful

Answer:

46p + 31

Step-by-step explanation:

Distribute : 5(6p + 5 ) to get 30p+25

Distribute : 2(8p + 3) to get 16p + 6

new expression : 30p + 25 + 16p + 6

Add these together to get : 46p + 31

Answer: 875

Step-by-step explanation:

You can set up proportions so it’s like: 1/350=2.5/x and then solve for x

Answer:9

Step-by-step explanation:

Think of it this way:

If 15=100%

then x= 60%

So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.

Answer:

First we need to subtract the hot fries. 20 - 1.99 = 18.01

he gets 11.77 so lets subtract it is 6.94 left so now divide by 6 is 1.5666666 or 1.6 per pack

Step-by-step explanation:

Answer:

a=9 , b=14

Step-by-step explanation:

Just do the operation (x+7)(x+2)

x(x)+x(2)+7(x)+7(2)

x^2+2x+7x+14

x^2+9x+14

So a=9 and b=14

Answer:

5.62

Step-by-step explanation:

8x-3y=36

8x-3×3=36

8x=36+9

x=5.62

Answer:

x= 45/8

Step-by-step explanation:

8x - 3y = 36

8x - 3(3) = 36

8x - 9 = 36

8x=45

x=45/8

Step-by-step explanation:the answer is option A as 1 • 3 =3 and 3+4=7

Answer:

0.643

Step-by-step explanation:

Given that :

{1,2,3,4,5,6,7,8,9,10,11,12,13,14}

Multiples of 2 : 2, 4, 6, 8, 10, 12, 14

Multiples of 3 : 3, 6, 9, 12

P(multiples o

(Multiples of 2 n multiples of 3) = {2,3,4,6,8,9,10,12,14} = 9

Probability = required outcome / Total possible outcomes

Hence,

P(multiple of 2 or 3) = 9 / 14 = 0.643

Answer:

9x+4

Step-by-step explanation:

perimeter= sum of all sides

perimeter= (2x+5)+ (x-4)+ 3(2x+1)

= 2x+5+x-4+ 6x+3

= 2x+x+6x+5+3-4

= 9x+8-4

=9x+4

Answer:

A= (6,76.5)

Incomplete question: Options

(a) Each triangular part and each rectangular part represents 1/2 the area of one square.

(b) Each triangular part has an area that is greater than the area of each rectangular part.

(c) Each triangular part and each rectangular part represents 1/4 the area of one square

(d) Each rectangular part has an area that is greater than the area of each triangular part.

See attachment for squares

Answer:

(a) Each triangular part and each rectangular part represents 1/2 the area of one square.

Step-by-step explanation:

Given

See attachment

Required

Which statement is true

Before the division, the area of both squares is:

[tex]Area = l * w[/tex]

After the division:

The area of the triangle is:

[tex]Area = \frac{1}{2} * base * height[/tex]

[tex]A_1 = \frac{1}{2} * l * w[/tex]

Substitute Area for l * w

[tex]A_1 = \frac{1}{2} *Area[/tex]

This equals half the area of the square

The area of the rectangle is:

[tex]Area = length * width[/tex]

The length of the rectangle is now half the length of the original square.

So, we have:

[tex]A_2 = \frac{1}{2} l * w[/tex]

Substitute Area for l * w

[tex]A_2 = \frac{1}{2} *Area[/tex]

From the values of A1 and A2, we can conclude that (a) is true

Answer: you do the length times width
