Answer:
Well, for (D), the answer would be 32.
Step-by-step explanation:
Because, 20 +12 =32. And 32 - 12 = 20. With the other ones that add, its the same way. You can just for example, if its -5 + b = -40, you can just go 5 - 40= which equals 35. Which should give you 40 if you add 35 and 5 together.
4 parts finished for 1 hour and worked for 6 hours so the no of parts fulfilled that day is: 4x6=24 parts
Answer:
x = 10
y = 4
Step-by-step explanation:
5x-4y=24 ------>( 1 )
-2x+7y=12 ------>( 2 )
( 1 ) × 2
(2) × 5
10x - 8y - 10x + 35y = 48 + 60
<u>27y</u><u> </u>= <u>108</u><u> </u>
27 27
y= 4
5x - 4× 4 = 24
5x - 16 = 24
x = 10
Answer:
(200+1,500) - 500 = 1,200 ft
Step-by-step explanation:
the hiker started at 200 ft then went 1500 more feet. (add it up) Then, she descends (goes down) 500 feet. So let's subtract 500 feet from the sum of 200 and 1500. ( (200+1500 equals 1700, then subtract 500 which will be 1200.) ) So, she is 1200 feet above sea level during the 10 minute break.
