Answer: -6. 4. -3,75. 37.
Step-by-step explanation: -20|+10-2²= -6, since a minus×minus give you a + therefore -2²=4.
2³+(-8)= 12-8=4, a minus×plus gives you a minus.
-2,50+(-1,25)=-2,50-1,25=-3,75. |-10|+|20|-5²-(-2)=-10+20+25+2=37.
Answer:
- 3 large boxes
- 9 small boxes
Step-by-step explanation:
The purchase can be grouped into groups containing one large box and 3 small boxes. Then each group will have 12 +3·6 = 30 granola bars.
Since 90 bars were purchased, the camp bought 90/30 = 3 groups of boxes of bars.
They purchased 3 large boxes and 9 small boxes of bars.
I find that if you transform fractions into decimals, they become marginally easier to work with. Nine over five in decimal form is one point eight. If we divide 1.8 by three (Jean-Claude and his two friends), then we come up with the answer 0.6, which, once turned back into a fraction, would be six over ten, or three over five.
-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.
-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.
-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.
-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.
-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.
So, the table/coordinates are:
(-2, 5)
(0, 2)
(2, -1)
(4, -4)
I hope this makes the process clear.
Round down to 54.6 because it is 5 or less.
