there are no like terms in that equation...

There are no like terms because each term has different set of variables, where a does not equal b does not equal ab.

Answer:

A=11/12

Step-by-step explanation:

1/3+a=5/4

1/3+a-1/3=5/4-1/3

1/3+a-1/3

Is this right and what's the answer for number 3?

Answers

Answer: Hello!

the problems are wrong:

in the first problem, you have 38 rocks, and you can separate them into groups of 10 or in single rocks.

You have 4 options to do it:

0 groups of 10, and 38 single rocks.

1 group of ten and (38 - 19) = 28 single rocks

(this is 10 rocks in the group of then + 28 single rocks = 38 total rocks)

2 groups of ten and (38 - 2*10) = 18 single rocks

3 groups of ten and (38 - 3*10) = 8 single rocks

and you can't form more groups of tens because you only have 8 single rocks left at this point.

in the second problem, the case is the same, now you have 30 pieces of felt and you can divide them into groups of 10 or in single pieces.

then the possible options are:

0 groups of ten and 30 single pieces

1 group of ten and (30 - 10) = 20 single pieces

2 groups of ten and (30 - 2*10) = 10 single pieces

3 groups of ten and (30 - 3*10) = 0 single pieces

in the third problem you need to write, similarly as i did, why you organized the rocks or the pieces as you did.

That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.

The total weight of 30 bags of flour and 4 bags of sugar is 42.6 kg. If each bag of sugar weighs 0.75 kg, what is the weight of each bag of flour?

Answers

The answer is: Each bag of flour weighs 1,32 kg.

If we the total weight of the bags is given, and we know both the number of bags of flour and sugar, and we also know the weight of each bag of sugar, then we have to find the unknown, which is X. 30 times X plus 4 times the weight of a bag of sugar would equal 42.6kg. Next step is to put the unknown on one side and the known values on the other side. We have 30 times X equals 42.6 minus 4 times 0.75.
To find X we need to divide the value with 30, or to sum up

30X + 4*0.75 = 42.6
30X + 3 = 42.6
X = (42.6 - 3) / 30
X = 1.32 kg

The weight of each bag of flour = 1.32 kg

Further explanation

The division operation is one of the basic arithmetic operations

Common signs used are $\large{\boxed{:}}}$ or $\large{\boxed{\slash}}$

The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel

The division is actually an iterative subtraction operation (as many as the number of divisors)

Division is the opposite of multiplying

The general form of division can be stated by:

$\large{\boxed{\bold{divident:divisor=quotient+remainder}}$
