ASHA 777 [7]

Answer:

x = 40

smaller angle is 80

larger angle is 100

Step-by-step explanation:

Supplementary angles add up to equal 180 degrees

Hence, x + 40 + 3x - 20 = 180

( note that we just created an equation that we can use to solve for x )

We now solve for x using the equation created

x + 40 + 3x - 20 = 180

step 1 combine like terms

x + 3x = 4x

40 - 20 = 20

we now have 4x + 20 = 180

step 2 subtract 20 from each side

180 - 20 = 160

we now have 160 = 4x

step 3 divide each side by 4

160 / 4 = 40

4x / 4 = x

we're left with x = 40

we now plug in 40 for x to find the value of each angle

x + 40

* substitute 40 for x *

40 + 40 = 80

3x - 20

* substitute 40 for x *

3 ( 40 ) - 20

3 * 40 = 120

120 - 20 = 20

so the larger angle is 100 degrees and the smaller angle is 80 degrees

A certain computer loses half of its value every two years. If the value of the computer after 3 years is 425, what was the init
IrinaVladis [17]

Answer:

1,700      

Step-by-step explanation:

The computation of the initial value of the computer is shown below:

Let us assume the value of a certain computer in the first year is X

In the second year, it is \frac{X}{2}

In the third year, it is \frac{X}{2}

In the fourth year, it is \frac{X}{4}

Now it is given that after 3 years, the value of the computer is = 425 i.e equal to

\frac{X}{4} = 425

So, X = 1,700

Hence, the initial value of the computer is 1,700
