Hi,
1/4of X means 1/4*x=16
then 3/4 of x means 3/4*x=?
we can write 3(1/4)x
put 1/4*x=16
3(16)=48

You might find it easiest to do this:  1) find the value of x, and then 2) find 3/4 of x.

If 1/4 of x is 16, multiply both sides of this equation by 4, to clear out the fraction.  What do you get?  This is the value of x you wanted.  Now multiply this value of x by 3/4.  The result is your answer.

Answer:

B. 1.-1,-2

Step-by-step explanation:

g(x) = x ^{3}  + 2 {x}^{2}  - x - 2

Substitute g(x)=0

0 =  {x}^{3}  + 2 {x}^{2}  - x - 2

Move the expression to the left

0 - {x}^{3}  - 2 {x}^{2}  + x + 2 = 0

Factor out -x^2 from the expression

-  {x}^{2}  \times (x + 2) + x + 2 = 0

Factor out (x+2) from the expression

(x + 2) \times ({x}^{2}  + 1) = 0

When the product of the factor equals 0, at least one factor is 0

x + 2 = 0

- {x}^{2}+ 1 > = 0

Solve for x

x =  - 2 \\ x =  - 1\\ x = 1

What is the surface area of this right prism?
Amiraneli [1.4K]

Answer:

Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by

surface area of prism = 2 * area of base + perimeter of base * H

So for the rectangular prism in your example..

surface area = 2LW + 2(L+W)H

= 2 * 7 * 4 + 2*(7+4)*5

= 56 + 2 * 11 * 5

= 56 +110

= 166 sq cm

Hope this helps

In order to solve the equation −3x + 6 = 5, the first step is to (1 point)
aliya0001 [1]
   −3x + 6 = 5  | -6   (first step is: "subtract 6 from both sides" <span>)
</span>
-3x = 5-6
-3x = -1      |  /(-3)   (second step is: "<span>divide by (-3) on both sides</span>" <span>)


</span>\displaystyle  \\ &#10;x =  \frac{-1}{-3} =  \boxed{\frac{1}{3} }

What could explain what happened when the time was equal to 120 minutes
tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

Alright, lets get started.

Lets split the given graph in three parts.

First part: 0 to 30 minutes

We can see between this period, 0 to 30 minutes, the distance from home keeps increasing. It means from 0 to 30 minutes, Eli is moving towards the library.

Second part: 30 to 120 minutes

between 30 to 120 minutes,the distance from home does not changes. It means during this period, Eli is at the library.

Third part : 120 minutes to 135 minutes

Between 120 to 135 minutes, the distance from home is decreasing.

It means Eli is returning home in that period.

It means, at 120minute, Eli started her bicycle , home from the library. Hence option (b)     :    Answer

Hope it will help :)
