Answer:
4
Step-by-step explanation:
2x+19=x+23
We simplify the equation to the form, which is simple to understand
2x+19=x+23
We move all terms containing x to the left and all other terms to the right.
+2x-1x=+23-19
We simplify the left and right sides of the equation.
+1x=+4
We divide both sides of the equation by 1 to get x.
x=4
30 kilograms

Answer:
The weights within this range are:
8.9
9.5
9.8
10.4
Step-by-step explanation:
The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:
9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)
8.5 ≤ x ≤ 10.5
Answer:
I say yes because when u solve it and flip the ( )'s, you get the same answer.
Step-by-step explanation:
Work:
(4/3 + 2/3) + 2
6/3 + 2
2 + 2
= 4
4/3 + (2/3 + 2)
4/3 + 8/3
12/3
= 4
Hope this helps!!
