Evaluate the expression when a=3 and b=4 2 2a+ b =

1 answer:

3 0

The answer you are looking for could either be 16 or 40. To solve the equation, you would follow the steps of PEMDAS. Since the 2 above the equation is an exponent, you'd first solve there.

Fill in "a" and "b", the equation will now say 2^2 * 3 + 4 = ?. Assuming that the exponent is meant to go with the 2 alone, 2 * 2 = 4. This leaves the equation to say 4 * 3 + 4 = ? Multiply 3 and 4 to get 12, then add 4 to get 16.

Fill in "a" and "b". This time, we're assuming that the exponent is going with 2 * 3 (originally 2a). Multiply 2 and 3 to get 6, then square 6 to get 36. Finally, add 4 to 36 to get 40.

I'm not quite sure where the exponent was meant to go, but I hope this helps!

How many arrangements of the seven letters in the word SYSTEMS have the E occurring somewhere before the M? How many arrangement

Snezhnost [94]

Answer: 720ways, 24ways

Step-by-step explanation:

Given the seven letter words "SYSTEMS", if E is always occurring before M it means E and M will always be together therefore they letter 'EM' will be taken as an entity to five us 6letters i.e SYST(EM)S.

This can then be arranged in 6!ways

6! = 6×5×4×3×2×1 = 720ways

Similarly, if the E somewhere before the M and the three Ss grouped consecutively, this means E and M must always be together as well as the Ss to give (SSS)YT(EM).

This means that the letters in the bracket can be taken as an entity to give a total of 4 entities. This can them be arranged in 4! ways.

4! = 4×3×2×1

4! = 24ways

Answer:

the answer is 46

Step-by-step explanation:

4×28/ 7×1 = 112/7

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

We already did that, and the GCF of 112 and 7 is 7.

We can now divide both the new numerator and the denominator by 7 to simplify this fraction down to its lowest terms.

112/7 = 16

and do the same for 3/4 out of 16 then add ur answers
