Here, If 28 inches is the diameter then,
C = π * diameter
C = 3.14 * 28
C = 87.92 in
Now, If the mentioned measurement is the radius, then:
C = 2 * π * r
C = 2 * 3.14 * 28
C = 175.84 in.
Hope this helps!
X=-1
x-7=2x-6
subtract x from both sides.
-7=x-6
add 6 on both sides.
Answer:The value of m for the given equation is, 35
Step-by-step explanation:
Given an equation: https://tex.z-dn.net/?f=x%5E%7B3m%7D%3D(x%5E%7B65%7D)*(x%5E%7B40%7D)
Use the above property on RHS in equation [1];
Since the base are same i.e, x ; we can add the exponents.
or
Using: , then a=b.
Therefore, 3m=105.
Divide 3 on both sides of an equation:
Simplify:
m=35
Therefore, the valur of m is, 35.
Ruby's hours will represent x+6
Svetlana's hours will represent 4(x+6)
Issac will represent x.
The equation would read:
x+(x+6)+(4(x+6))=126
x+x+6+4x+24=126
6x+30=126
Subtract 30 from both sides.
6x=96
Divide 6 on both sides to get x by itself.
x=16
So:
Issac worked 16 hours
Ruby worked 22 hours
Svetlana worked 88 hours.
To check your answer, plug in the values:
16+22+88=126
126=126
Hope this helps.
