Step-by-step explanation:

Answer:

4) no

5) 8x + 1.50

6) 1, 2, 0, 5

Step-by-step explanation:

4) no- first step is to subtract 10

5) number of apples times price of $8 plus a single purchase of $1.50

6) all values greater than -2

Answer:

See the expression below

Step-by-step explanation:

Given data

We have the expression  

-4x+y=11-----------1

from 1 make y subject of formula we have

y=100+4x

Make x subject of the formula we have

-4x=11-y

divide both sides by -4

x=(11-y)/-4

the third one I think please see be right

Answer:

Total salary = Rs.36,000

Step-by-step explanation:

Given:

Amount saves = Rs. 2,880

Percent of saving = 8% = 0.08

Find:

Total salary

Computation:

Total salary = [Amount saves] / Percent of saving

Total salary = 2,880 / 0.08

Total salary = Rs.36,000

Answer:

40

Step-by-step explanation:

You write down the %/100 = is/of 1st

So what you want to do is remove the percentage first and the place 150% And then place 60 on the "is" Numerator. And as u can see you do 100 * 60, that'll give you 600 and then the 150% is left alone, so you divide 600 and 150 And the answer is going to be 40

Answer:

40

Step-by-step explanation:

x = 60 ×  100 /150

x= 40

Answer:

Step-by-step explanation:

Write an equation:

the slope would be -6 / 2 = -3

in point slope form:

y = -3(x+2)

simplify:

y = -3x - 6

Check if (2, 6) is a point:

6 = -3 * 2 - 6

6 = -6 - 6

6 = -12

Not true. The point is not on the graph.

Step-by-step explanation:

y = x-3

So, y + 3 = x

x = y + 3

if x = 7

y = 7 - 3 = 4

if y = 1

x = 1 + 3 = 4

Answer:

Step-by-step explanation:

Here u go

Answer: The answer is 96

Step-by-step explanation: your have to measure the length by width(6x12) then subtract 12 from 20 which is 8 then divide by 2 and you get 4 so when you have 6x4=24÷2(because its a triangle)=12 since theres 2 triangles multiply by 2 so add 12+12+72 and you get 96

Answer:

slope is -1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let ( x1 , y1) = ( -4 ,1 )

(x2 , y 2) = ( -2 , -1 )

Now

slope (m)

= ( y2 - y1) / (x2 -x1)

= ( -1 - 1) / ( - 2 + 4)

= -2 /2

= - 1

Mode is the number that occurs the most so here the mode is 56

Answer:

6x + 2 and 2x + (x + 1) + 2x + (x + 1)

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Length = 2x

Width = x + 1

Perimeter of a rectangle = 2(length + width)

= 2{2x + (x + 1)}

= 2(2x + x + 1)

= 2(3x + 1)

= 6x + 2

Perimeter = length + width + length + width

= 2x + (x + 1) + 2x + (x + 1)

The ratio 4:7 means for every 4 men there are 7 women.

Divide total number of men by 4:

487/4 = 121.75

Multiply that by 7:

121.75*7 = 852.25 Round to the nearest whole number.

There is approximately 852 women.

Answer:

0.65

Step-by-step explanation:

Given equation:

P = 0.65n

where,

P = price

n = number of pears

What is the constant of proportionality?

The constant of proportionality is 0.65

For example

Find P when n = 2

P = 0.65n

= 0.65(2)

P = 1.3

Answer:

-.25

Step-by-step explanation:

1/4 is equal to a quarter, or .25. its negative because the fraction is negative

Answer:

-.25

Step-by-step explanation:

1/4 is like one quarter which is 25 cents so .25, but u said negative so 0.25

Answer:

y=-2x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-3)/(2-(-1))

m=-6/(2+1)

m=-6/3

m=-2

y-y1=m(x-x1)

y-3=-2(x-(-1))

y-3=-2(x+1)

y=-2x-2+3

y=-2x+1

Question

Daniel expanded the expression as shown. What errors did he make? Select three options.

[tex]-2(-8x-4y+3/4)=-10x-8y-1 \frac{1}{4}[/tex]

A. The first term should be positive.

B. The second term should be positive.

C. The last term should be -1 1/2, not -1 1/4.

D. He divided -8 by -2 instead of multiplying -8 by -2.

E. He did not simplify the expression completely.

Answer:

Daniel's errors are (a), (b) and (c)

Step-by-step explanation:

To do this, we only need to solve the expression on the left.

So, we have:

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

Open bracket

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

[tex]-2(-8x-4y+3/4)=16x + 8y - \frac{2 * 3}{4}[/tex]

[tex]-2(-8x-4y+3/4)=16x + 8y - \frac{6}{4}[/tex]

[tex]-2(-8x-4y+3/4)=16x + 8y - 1\frac{1}{2}[/tex]

From the expression, we can see that:

So, Daniel's errors are (a), (b) and (c)
