Can anyone help me with this please I really need help

Answer:

26

Step-by-step explanation:

[(7+3)5-4]/2+3

-To solve this equation you have to use PEMDAS

P- Parentheses

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction-

- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])

Step 1) [(10)5-4]/2+3

- First you do "P," parentheses, so you add 7+3=10

Step 2) [50-4]/2+3

- Next you do "M," multiplication, and multiply 10x5=50

Step 3) [46]/2+3

- Then you do "S," subtraction, and subtract 50-4=46

(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)

Step 4) 23+3

- Now we do "D," division, and divide 46/2=23

Step 5) 23+3=6

- Finally we do "A," addition, and add 23+3=26 so the answer is 26

(FYI: "/" means division)

Answer:

$8.25/scarf

Step-by-step explanation:

Divide the cost of the 9 scarves by the number of scarves.

$74.25/9 = $8.25

The unit price is $8.25 per scarf

Answer:

$3990

Step-by-step explanation:

So first,you need to add the dollars that Sarah spend and which is equal to $1330($360+$970) and you need to subtract the money that Sarah spend($1330) and the budget of her money ($5320) so which is $5,320-$1,330 so the answer is $3,990

i think, your question didnt make to much sence

[tex] \frac{6 {x}^{2} + 7x - 3 }{ - 3 {x}^{2} + x } \\ = \frac{6 {x}^{2} + 9x - 2x - 3 }{ - 3 {x}^{2} + x } \\ = \frac{3x(2x + 3) - 1(2x + 3)}{ - {3x}^{2} + x} \\ = \frac{(2x + 3)(3x - 1)}{x( - 3x + 1)} \\ = \frac{(2x + 3)(3x - 1)}{ - x(3x - 1)} \\ = \frac{(2x + 3)}{x} \\[/tex]

Answer:

6.3%

Step-by-step explanation:

We're gonna use the simple interest formula: A = P(1 + rt)

A = Final amount (500 + 15.75 = 515.75)

P = Starting amount (500)

r = rate (?)

t = number of years (.5 since it's been half a year)

515.75 = 500(1 + 0.5r)

Disitribute the 500 to the equation inside the parenthesis

515.75 = 500 + 250r

Subtract 500 from both sides

515.75 = 500 + 250r

- 500   - 500

15.75 = 250r

Divide both sides by 250

15.75/250 = 250r/250

r = 0.063

Answer:

the desiner shpuld exept it

Step-by-step explanation:

Step-by-step explanation:

x= children

y= adult

First equation: x+y= 2900

Second equation: 1.50x + 4y= 6100

From first equation: x+y= 2900

x= 2900-y, becomes the third equation

Second equation: 1.50(2900-y) + 4y= 6100

4350-1.50y+ 4y= 6100

2.5y = 1750

y= 700

700 adults

Thrid equation: x= 2900-700

= 2200

2200 children

So total have 700 adults and 2200 children

Answer:

One half of 8 1/8 is 4 1/16

Explanation:

Half of 8 is 4, and since the denominator of the fraction is 8, you'd have to double up to 16, since that's how fractions work.

Answer:

Set up an equation (you can use the distance formula as an equation). The distance formula is Y2-Y1/X2-X1.

2-(-4)/x-5=-3

6/x-5=-3

Multiply both sides by x-5.

6=-3(x-5)

Distribute the -3 to the terms in the parentheses.

6=-3x+15

Subtract 15.

-9=-3x

Divide both sides by -3.

3=x

So, the missing number of the coordinate is 3.

Answer:

3/2

Step-by-step explanation:

Image a bit blurry, but I'm counting whoever wrote this was sane enough to pick integer values.

[tex]f(2) = 1; f(4)=4[/tex]

Average rate of change is the difference in f divided by the difference in x:

[tex]\frac{\Delta f(x)}{\Delta x} = \frac{4-1}{4-2} = \frac32[/tex]

13 6/8 or 13 3/4 they are both right answers

Answer:

the vertex is 70 degrees and the other 2angles are 55 degrees each

in a triangle the angles must total to 180 degrees.

if the exterior angle is 110 degrees the supplementary angle of this angle would be = 180-110= 70 degrees

as it is an isosceles triangle the other two angles must be equal.

such that x+x+70= 180 , where x are the angles of the base

2x= 180-70

2x=110

x=110/2

x= 55

Answer:

3x + 2y = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{3}{2}[/tex] , then

y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation

To find c substitute (6, - 8 ) into the partial equation

- 8 = - 9 + c ⇒ c = - 8 + 9 = 1

y = - [tex]\frac{3}{2}[/tex] x + 1 ( multiply through by 2 to clear the fraction )

2y = - 3x + 2 ( add 3x to both sides )

3x + 2y = 2 ← in standard form

Answer:

the answer is c, 19,000,000.
