150/5=30

Answer:

Option D is the answer hope it helps :)

Step-by-step explanation:

Answer:

a) =5+2p+6

= 11+2p

b)=3+5x-10

= -7+5x

c)= 10+6b+10

= 20+6b

d) = 7s-4s+4

= 3s+4

f)=2x+2+3

= 2x+5

g)= 6w+6+5w

= 11w+6

h)= 2p-2p+7p

= 7p

i)= 8x- 12x + 3x

= -1x

Hope that helped

Answer:

Step-by-step explanation:

I don't do this question the way it is outlined. My way is a bit shorter.

The general equation is y = mx + b

You want the slope to be - 1/5 which you just read from the given equation.

So, so far you have y = -1/5x + b

Now for the point which is (5,-4)

x = 5

y = - 4

-4 = -1/5 * 5 + b

-4 = -1 + b

b = -4 + 1

b = - 3

the equation is y = -1/5 x - 3

===========================

Now let's do it your way.

y - y1 = m(x - x1)

x1 = 5

y1 = - 4

m = - 1/5

y - - 4 = -1/5(x - 5

y + 4 = -1/5x + 1        Take 4 from both sides

y = -1/5 x + 1 - 4

y = -1/5 x - 3

Same answer. I never knew that was possible.

Answer:

A= -53/7

Step-by-step explanation:

1 x 10 -1 x 7 x A=7 x 9

10-7A =7 X 9

10-7A=63

-10 -10

-7A=53

A= -53/7

Answer:

  55.9%

Step-by-step explanation:

The percentage is found by multiplying the fraction by 100%.

  19/34 × 100% ≈ 55.9%

About 55.9% of the class are girls.

Given:

5) The expressions are

[tex]16x+24y+32[/tex]

[tex]8(2x+3y+4)[/tex]

[tex]4(4x+24y+8)[/tex]

7) The expression is

[tex]7(3-x)+15x[/tex]

To find:

5) Whether the given expressions are equivalent.

7) simplified form of given expression.

Solution:

5)

First expression is

[tex]16x+24y+32[/tex]

Second expression is

[tex]8(2x+3y+4)[/tex]

[tex]=8(2x)+8(3y)+8(4)[/tex]

[tex]=16x+24y+32[/tex]

Third expression is

[tex]4(4x+24y+8)[/tex]

[tex]=4(4x)+4(24y)+4(8)[/tex]

[tex]=16x+96y+32[/tex]

Therefore, the simplified forms of given expressions are [tex]16x+24y+32,\ 16x+24y+32,\ 16x+96y+32[/tex] respectively. It means only first and second expressions and equivalent.

7)

We have,

[tex]7(3-x)+15x[/tex]

[tex]=7(3)+7(-x)+15x[/tex]

[tex]=21-7x+15x[/tex]

[tex]=21+8x[/tex]

Therefore, the simplified form of given expression is [tex]21+8x[/tex].

Given:

5) The expressions are

7) The expression is

To find:

5) Whether the given expressions are equivalent.

7) simplified form of given expression.

Solution:

5)

First expression is

Second expression is

Third expression is

Therefore, the simplified forms of given expressions are  respectively. It means only first and second expressions and equivalent.

7)

We have,

Therefore, the simplified form of given expression is .
