Answer:
d) She cut the wood into pieces that are each 1 1/2 meter long.
Step-by-step explanation:
Marla sawed a 12-meter wood plank into 8 equal pieces.
Hence,
8 equal pieces = 12 meter
1 equal pieces = x meter

x = 12/8 meters
x = 3/2 meters long
x = 1 1/2 meters long.
Therefore, Option d is the correct Option
Answer:
24 inches
Step-by-step explanation:
15 divided by 3 equals 5, so you need to do to the other side. Which would be X divided by 3 equals 8. 24 divided by 3 equals 8
The equation is b-a= 21;
2b-5a = 18
a=8 and b= 29
therefore 29-8= 21
2 (29) -5 (8) = 18
58-40=18
Answer:
7kg of potatoes cost 56 R (dollars)
Step-by-step explanation:
First, we have to find the unit price of 1kg of potatoes. To do this we divide <em>24 by 3</em>. That's <em>8</em>. Each kg of potato costs 8 dollars.
Now, all we have to do is multiply <u><em>8 by 7</em></u>.
8 is the unit rate/kg and 7kg is the amount they are asking.
<u><em>8x7=56</em></u>
7kg of potatoes cost 56R
