Answer:
The number of people who owned computers last year was 1500.
Step-by-step explanation:
The information provided is as follows:
- The number of people who own computer in a small town is 2400.
- This is 60% more than the number who owned computer last year.
Let <em>X</em> denote the number of people who owned computer last year.
And <em>Y</em> denote the number of people who owned computer this year.
Then:
Y = X × (100% + 60%)
Thus, the number of people who owned computers last year was 1500.
Answer: z = -3 , y = 2 , x = 2
Answer:
StartFraction x over 7.5 EndFraction = StartFraction 12 over 1 EndFraction
Step-by-step explanation:
Here, in this question, given that Rosa earns $12 in an hour, she earns x dollars in 7.5 hours. So we are interested in finding the value of x.
Let’s write this in terms of proportion;
$12 = 1 hour
$x = 7.5 hours
$12 * 7.5 hours = $x * 1 hour
So this can be rewritten as;
$x/7.5 = $12/1 hour
The radius of a circle is half the length of the circumference.
So multiply 12 by itself and you get 24.
The answer is C.
Answer:
X = 5 unit
Step-by-step explanation:
Given as , ABC is a Triangle ,
AC extended to through C to D
∠BAC = 6x + 10
∠ABC = 6x - 10
∠BCD = ∠ 8x + 20
When c extended to D then , ∠BCD is an external angle
∵ <u>External angle = Sum of opposite internal angles</u>
Or ,∠BCD = ∠BAC + ∠ABC
Or, ∠ 8x + 20 = 6x + 10 + 6x - 10
Or, ∠ 8x + 20 = 12x
Or, 12x - 8x = 20
∴ 4x = 20
So, x = 
= 5
Hence the value of X = 5 unit Answer
