Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
Let, the age of Kim = x
Then, Jordan's age = x + 7
It is given that, 4(x + 7) = 200
a) Equation would be: 4x + 28 = 200
b) Now, 4x = 200 - 28
x = 172/4
x = 43
So, Kim is 43 Years old.
c) Age of Jordan = x + 7
= 43 + 7 = 50
In short, Age of Jordan is 50 Years
Hope this helps!
Divide the first one by the second and the answer will be B.
Answer:
5n-8
Step-by-step explanation:
Because this is an arithmetic progression, there is simply an addend that is being added to every number. Because that is 5, the expression, for now, would be 5n. However, the progression does not start at 0, so we will have to subtract 3, and then it would be 5n - 3. We're still not at the answer; this is because the first term starts at 1, not 0. We will have to account for that, so subtract the coefficient, or 5, from the whole expression. That would be 5n - 8, and that would be the answer.
Answer:37 degrees
Step-by-step explanation:
90 (right triangle always has a 90 degree angle) + 53 = 143
There are 180 degrees in a triangle so,
180-143 = 37
