6 + 2x = 6
2x = 0
x = 0
answer: x = 0 and y = 2 or (0,2)
Answer:
x ≤ 15
Step-by-step explanation:
25x + 225 ≤ 600
Subtract 225 from both sides and get
25x ≤ 375
Divide 25 from both sides and you´ll get
x ≤ 15
A) 4a+3w
b) 2b+h
c) 3(w+h)
d) (4a+3w)(2b+h) - 3(w+h)
just expand brackets for d and simplify
7.5 %
Step-by-step explanation:
We by finding how far from the mean the 999 volume caps are, using z score;
Z = (x – μ) / σ
Z = (999 – 998) / 7
Z = 0.143
We use the z-table to find the confidence levels;
= 85%
= 0.85
Since we are finding proportion of bottles have volumes greater than 999
mL;
1 – .85 = .15
0.15/2 = 0.075
= 7.5%
