Answer:
18
Step-by-step explanation:
since its the sum of the dots
The minimum range = 20.5 - 0.045 = 20.455
The maximum range = 20.5 + 0.045 = 20.545
The range is between 20.455 and 20.545
Writing this as inequality
20.455 ≤ x ≤ 20.545
Correct answer: B
Answer:
2x+3x=150 ( sum of opposite interior angle of triangle is equal to the exterior angle)
5x=150
x=150/5
x=30
Answer:
Jerry's weight is 36kg and tom's weight is 66kg
Step-by-step explanation:
According to the given condition:
Let,tom's weight =x
Jerry's weight=y
So,
X=2y-6 ---(1)
X+y=102-----(2)
Put value of x from eq 1 in 2
2y-6+y=102
3y-6=102
3y=102+6
3y=108
Y=108/3=36
Jerry's weight is 36.
Put value of y in eq 1
X= 2(36) -6
X=72-6
X=66
So, Tom's weight is 66kg
The first part of this sentence, "<em>5 subtracted from w</em>", can be written as:
w - 5
Now, to express the relation "<em>less than or equal</em>", we use the symbol:
≤
And the last part of the sentence, "16", continues the same.
Then, joining those three parts, we obtain the inequality:
w - 5 ≤ 16
