Answer:
x = -2
Step-by-step explanation:
5(-2x - 1) = -10x -5
-10x -5 - 5x + 2 = 27
-15x -3 = 27
+3 +3
-15x = 30
x = -2
Answer:
3a = 
Step-by-step explanation:
Given
2a + 4b = 5 ← substitute a = 3b into the equation
2(3b) + 4b = 5
6b + 4b = 5
10b = 5 ( divide both sides by 10 )
b = 
= 
Now
a = 3b = 3 × = 
, thus
3a = 3 × =
Turn 7 into a fraction so it can be multiplied. > 7/1
Multiply 7/1 by 1/3.
7/1 × 1/3 = 7/3
Simplify 7/3 into a mixed number.
7/3 = 2 1/3
Nolan will need 2 1/3 lbs of turkey.
To answer your question it would be 7
7*7 is 49 hope that a helps:)
Answer:
The range of acceptable values for production = (16-0.15, 16+-0.15)
= (15.85, 16.15) oz.
Step-by-step explanation:
Boxes are randomly weighted to ensure the correct amount.
If the discrepancy in weight is more than 0.15 oz, the production is stopped.
Correct weight = 16 oz
Acceptable discrepancy = 0.15 oz.
Hence acceptable level is between 16-0.15, and 16+0.15
simplify to get in interval form the acceptable range as
(15.85, 16.15)
