Step-by-step explanation:

Hey there!

Given;

[tex] = {x}^{2} + 3x[/tex]

~ Take "X" common.

=[tex]x(x + 3)[/tex]

Therefore, "x" and "x+3" are the factors if the expression.

Answer: She has left $32.8 after she pays the hair stylist.

Step-by-step explanation:

Money Gali has = $100

Charge per hair style = $56

Tip percent = 20%

Total charge for hair styling = Charge per hair style + Tip

= $ (56+ 20% of 56)

= $ (56+0.2 x 56)

= $ (56+11.2)

= $ 67.2

Money left = Money Gali has - Total charge for hair styling  

= $ (100-67.2)

= $ 32.8

Hence, she has left $32.8 after she pays the hair stylist.

Answer:

  (0.5, -2.5)

Step-by-step explanation:

Each of the coordinates of B(1, -5) is multiplied by the scale factor, 0.5:

  B' = (0.5·1, 0.5·(-5)) = (0.5, -2.5)

The coordinates of B' are (0.5, -2.5).

Answer:32 mins

Step-by-step explanation:you divide 3 hours wich is 180 divide it by 4 days wich is 96 hours

Answer:

D I think

Step-by-step explanation:

Answer:

360 > 120 +60n (subtract 120 from both sides)

240> 60n (divide both sides by 60)

4>n ( I always flip it so its the right way)

n< 4 days or B

Answer:

(B). - 7 ≤ x < 12

Step-by-step explanation:

- 7x - 50 ≤ - 1 ⇔ - 7x ≤ 49 ⇒ x ≥ - 7  

and

- 6x + 70 > - 2 ⇔ - 6x > - 72 ⇒ x < 12

- 7 ≤ x < 12

Answer:

A

Step-by-step explanation:

Answer:

y=-1/3x-1

Step-by-step explanation:

Perpendicular lines have slope that are opposite sign and reciprocals

3x-y=12 has a slope of 3, therefore perpendicular line must have slope of -1/3

2=-9(-1/3)+b

2=3+b

b=-1

Answer:

The Best answer will be D having to add 7 then subtracting 8, becoming -1,  then dividing to become D.

Step-by-step explanation:

Answer: Capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.

Step-by-step explanation:

Let x = Capacity of Marshfield Stadium.

y = Capacity of Bowden.

As per given, we have

x - y = 7,675               (i)

x+y  =  210,355               (ii)

2x = 218030    (iii)

[tex]\Rightarrow\ x= \dfrac{218030}{2}\\\\\Rightarrow\ x= 109015[/tex]

Put value of x in (i) , we get

109015 - y = 7675

⇒ y= 109015 - 7675

⇒ y= 101,340

Hence, capacity of Marshfield Stadium is 109,015 and capacity of Bowden is Bowden.

Answer:

Angle 3= 37 degrees, Angle 2 = 143 degrees, Angle 4= 143 degrees

Step-by-step explanation:

Angle 3 is across from Angle 1 so they are equal to each other. Now to find Angles 2 and 4, cover angles 2 and 3 with your hand so you are just looking at 1 and 4, they are on a line. Lines are 180 degrees, so since angle 1 we know is 37 degrees, then 180-37= 143 degrees for angle 4. Now, 2 and 4 are opposites of each other, and share the same value of 143 (just like how we found angles 1 and 3 to be equal bc they are across from each other)

Step-by-step explanation:

Answer:

x = -8

y = -2

Step-by-step explanation:

The variable x in this system of equations is already isolated. Therefore, we can substitute it into the other equation and solve for y.

7(2y - 4) + 5y = -66

14y - 28 + 5y = -66

19y = -66 + 28

y = -2

Then we solve for x

x = 2(-2) - 4

x = -8

Answer:

x = 12

Step-by-step explanation:

First, eliminate the fractional coefficient 1/2, by multiplying all three terms by 2:

-24 + x = -12

Adding 24 to both sides isolates x:  x = -12 + 24, or x = 12

Answer:

[tex]1\frac{1}{3}[/tex] cups of flour.

Step-by-step explanation:

Given that:

[tex]w[/tex] is the number of cups of water to be mixed with flour for making tortillas.

[tex]f[/tex] is the number of cups of flour to be mixed with water for making tortillas.

Relation between [tex]w[/tex] and [tex]f[/tex] is given by the equation:

[tex]w=0.75f[/tex]

To find:

Number of cups of flour to be added if number of cups of water to be used is 1.

Solution:

We are given an equation with two variables.

Value of one variable is given and we have to find the value of other variable.

[tex]1=0.75f\\\Rightarrow f = \dfrac{1}{0.75}\\\Rightarrow f = 1.33[/tex]

Number of cups of flour to be added = [tex]1\frac{1}{3}[/tex]

Answer:

x=154/115

Step-by-step explanation:
