Let n be the number unknown

2(n)-2=n+64

Use distribute property to remove parenthesis

2n-2=n+64

Move all n term to left side

2n-n-2=64

Combine like terms with n

N-2=64

Now add integer to right side by doing opposite sign

N = 64+2

Solve for n

N=66

Your number is 66

To check you substitute

2(66)-2=66+64

130. =130

Ludmilka [50]

Answer:

Answer in explanation

Step-by-step explanation:

In this question, we would be examining the validity of some statements on the number π(pi)

π Is a whole number?

This is wrong, π is a fraction of 22 to 7 parts I.e 22/7

π Is double the radius?

This is wrong. It is the diameter that is double the radius

π Is approximately 3.14?

This is correct to an extent. The actual value in decimal is around 3.142857142857143 which makes the 3.14 somehow correct

π represents the ratio of the circumference of the circle to the diameter?

This is correct.

Mathematically, circumference C = π * diameter D

Hence C/D = π

π Is approximately 22/7?

This is correct. This is the ratio used for π

The sum of three numbers is 120.The third number is 3 times the second. The first number is 5 more than the second. What are the

AVprozaik [17]

Answer:

Sum of 2 no. 120

Let second no. be x

Therefore, first no. =x+5

Therrfore,third no. =3x

Thetefore,x+5+x+3x=120

5x+5=120

5x=115

x=23.

Therefore, 1st no.=28

Second=23

and third=69

A ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour. Which type of functions be

UNO [17]

Answer:

Option B. Linear

$y=4x+18$

Step-by-step explanation:

Let

x----> the time in hours

y----> the total inches of snow on the ground

we know that

The function that best model this situation is the linear function

$y=mx+b$

In this problem

$m=4\frac{in}{h}$

$b=18\ in$ ----> the y-intercept

substitute

$y=4x+18$

Explain why the diagram displqyed on the right cannot represents a real object

Vikentia [17]

Notice how the frontmost corner is the only corner stacked. Then, notice how the shape comes together without bending at all. This is impossible because the only way this could be a real shape is if the two angles on the left and right bend upward. Because this doesn't happen, the shape is impossible
