Of 2x – 3y + 5 – (x – 3y) = 11 – 2x, what is the value of x?
Novay_Z [31]

Answer:

  2

Step-by-step explanation:

2x – 3y + 5 – (x – 3y) = 11 – 2x . . . . . given

2x -3y +5 -x +3y = 11 -2x . . . . . . . . . . .eliminate parentheses

x +5 = 11 -2x . . . . . . . . . . . . . . . . . . . . . collect terms

3x = 6 . . . . . . . . . . . . . . . . . . . . . . . . . . add 2x-5

x = 2 . . . . . . . . divide by 3

The value of x is 2.

HELP ASAP!! please help me answer 2 and 5.
irga5000 [103]

Answer:

b

Step-by-step explanation:

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.

A gift box has a volume of 450 cubic inches. The width of the box is 4 inches less than the length. The height is twice the widt
VashaNatasha [74]

Answer:

width = 5 in

length = 5+4=9 in

height = 2(5)= 10 in

Step-by-step explanation:

A gift box has a volume of 450 cubic inches.

Let 'w' be the width of the box

The width of the box is 4 inches less than the length.

length = w+4

The height is twice the width.

height = 2 \cdot width

height = 2w

Volume of box = length times width times height

V=(w+4)(w)(2w)

450=(w+4)(w)(2w)

450=2w^3+8w^2

2w^3+8w^2-450=0

\quad 2\left(w-5\right)\left(w^2+9w+45\right)=0

w-5=0

w=5

\quad\left(w^2+9w+45\right)=0, this gives two complex values

so width = 5

length = 5+4=9

height = 2(5)= 10

Answer:

<u>So option 4; </u>\frac{35}{100}<u> is the correct option</u>

Step-by-step explanation:

First, we need to convert \frac{2}{10} so it's denominator is 100. To do so, we will multiply the numerator and denominator by 10

\frac{2}{10} *\frac{10}{10} = \frac{20}{100}

Second, we need to add the two fractions to get the current total distance walked. Remember, when adding fractions, the denominator does not change.

\frac{45}{100} + \frac{20}{100} = \frac{65}{100}

Now that we have the total distance walked, we need to subtract that to 1 mile. 1mile=\frac{1}{1} = \frac{10}{10} =\frac{100}{100}

\frac{100}{100} -\frac{65}{100} = \frac{35}{100}

So option 4; \frac{35}{100} is the correct option
