Is 2x + 3 + 7x equivalent to the expression 3(3x + 1) ?

Answer: i think A(t)=30000−550(t−1)

Step-by-step explanation:

Let hours = x

She can work a maximum of 30 hours so x can be any number from 30 or below.

The inequality would be: X <= 30

Answer:

Let the maximum time be x

She can work 30 hrs or below ( maximum of 30 hrs)

Therefore, the equation is

[tex] \huge \boxed{x \leqslant 30 \: hours}[/tex]

Answer:

x=-3/2y+2

y= y=−3x+6

Step-by-step explanation:

solve for x.

2x+3y=4

Add -3y to both sides.

2x+3y+−3y=4+−3y

2x=−3y+4

Divide both sides by 2.

2x/2= -3+4/2

x= -3/2 y+2

solve for y.

y+3x=6

Add -3x to both sides.

3x+y+−3x=6+−3x

y=−3x+6

Answer:

9/16

Step-by-step explanation:

(5/8 * 2/2) - (1/16 - 1/1)

10/16 - 1/16

10-1//16 = 9/16

5/8 - 1/16 = 9/16

(5*16) - (1*8) / 8 * 16

80-8/ 128

72/128

72/8

128/8= 9/16

5/8 - 1/16 = 9/16

Answer: 1/40

Step-by-step explanation:

Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:

= 3 3/4 + 2 3/5

= 3 15/20 + 2 12/20

= 5 27/20

= 6 7/20

We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:

= 6 3/8 - 6 7/20

= 6 30/80 - 6 28/80

= 2/80

= 1/40

Answer:

(x × y) - 6 < 30

xy - 6 < 30

xy < 30 + 6

xy < 36

Step-by-step explanation:

Let us represent:

First number = x

Second number = y

The product of two numbers decreased by six is less than 30.

The algebraic expression is given as

(x × y) - 6 < 30

xy - 6 < 30

xy < 30 + 6

xy < 36

Answer:

= 7/ 8

Step-by-step explanation:

We can find the slope using the slope formula

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

    = ( 10-3)/( -2 - -10)

    = ( 10-3)/( -2 +10)

    = 7/ 8

Answer:

yes this is so normal to do

Answer:

C

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] m + 5 = 17 ( subtract 5 from both sides )

[tex]\frac{2}{3}[/tex] m = 12 ( multiply both sides by 3 to clear the fraction )

2m = 36 ( divide both sides by 2 )

m = 18 → C

I don't know if you need to solve the x but that what are going to do

Answer: 13/6

Step-by-step explanation:

2x - 3 = 9-4x

2x + 4x = 9 + 4

6x = 13

X= 13/6

Or

X= 2.16

216cm^2

Volume of cube= 216 ft^3

l^3= 216

l= Cube root of 216

l= 6

SA=6*l^2

=6*6*6

=216 cm^2

[tex]\huge\boxed{t=3}[/tex]

Step-by-step explanation:

[tex]-5(t+3)=-30[/tex]

[tex]-5(t+3)=-30[/tex]    divide both sides by (-5)

[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]

[tex]t+3=6[/tex]       subtract 3 from both sides

[tex]t+3-3=6-3\\t=3[/tex]

[tex]-5(t+3)=-30[/tex]       use the distributive property a(b + c) = ab + ac

[tex](-5)(t)+(-5)(3)=-30[/tex]

[tex]-5t-15=-30[/tex]     add 15 to both sides

[tex]-5t-15+15=-30+15[/tex]

[tex]-5t=-15[/tex]         divide both sides by (-5)

[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

Answer:

7a - 21 + 28b

Step-by-step explanation:

using the distributive property we can multiply 7 to the numbers in the paretheses. doing this we get:

7a - 21 + 28b

Answer:

The actual wall- 30

The width of the window blueprint- 1.5

Step-by-step explanation:

The actual wall- its the last answer you get for length

I just know the answer

The width of the window in the blueprint will be 2.7 inch.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

From the given table choose;

⇒ (x₁ , y₁ ) = (3, 5)  &  (x₂, y₂ ) = (3, 5)

Since, We know that equation of line is,

⇒ y – y₁  = ((y₂  – y₁)/(x₂ – x₁ )) (x – x₁)

⇒ (y - 3) = ((10-5)/(6-3))(x - 3)

⇒ 3(y - 3) = 5(x - 3)

⇒ 3y  = 5x -15+9

⇒  5x-  3y = 6  ….(i)

This is the required equation.

Given that; the length of wall on blue print = 10 inch

Then, put x = 10 in equation (i) we get;

⇒ 5x10 – 3y = 6

⇒ -3y = 6 - 50

⇒ y = 14.6 ft

The actual length be = 14.6 ft

And, Also given that actual width of window = 2.5 feet

Then put y = 2.5 in equation (i) we get

⇒ 5x – 7.5 = 6

⇒ 5x = 13.5

⇒ x = 2.7 inch

Thus, The width of the window in the blueprint is 2.7 inch.
