I need help. So supposed that you have three diffrent lenghts of linking cubes

as shown below . ( 5 blacks, 3 whites 2, reds) Assume that you have as many of these lengths as you need, but you may not take them apart.

a) 25 d) 29
b) 20 e) 30
c) 18 f) 32

Grade 7 Math.

pls answer as soon as posible.

Try writing the question exactly and completely as given to you without interpretation. I don't know what you are looking to find.

very good

It seems like you have a set of linking cubes with different lengths, and you need help determining which combination of these cubes can be used to make different totals. To find out which combinations can be used to reach the given totals, you'll need to experiment with different combinations of cubes.

Here's how you can approach each of the given totals:

a) To make a total of 25, you can use 5 black cubes.

b) To make a total of 20, you can use 2 red cubes and 3 white cubes.

c) To make a total of 18, you can use 2 red cubes, 3 white cubes, and 1 black cube.

d) To make a total of 29, you can combine the combinations from a) and b) or a) and c). For example, you can use 5 black cubes and 2 red cubes for a total of 25, and then add 2 white cubes to reach a total of 29. Alternatively, you can use 5 black cubes, 2 red cubes, and 1 white cube for a total of 27, and then add 2 more white cubes to reach a total of 29.

e) To make a total of 30, you can use the combination from d) and add 1 more white cube.

f) To make a total of 32, you can use 5 black cubes, 3 white cubes, and 2 red cubes.

Remember, there may be multiple combinations to achieve the same total. Experiment with the different cube lengths and try different combinations until you find the correct number of cubes needed for each total.
