Step-by-step explanation:
what answer is needed ? the result of the calculation ?
I assume this is the case.
remember that regarding the sequence of operations brackets are first, then exponents, then "dot" operations (× and ÷), and only at the very least come the "dash" operations (+ and -).
and that a combination of - + or + - results in -.
14 + 16 ÷ 2³ - (12 + 3²) ÷ 7 + 2 × (-5) =
14 + 16 ÷ 2³ - (12 + 9) ÷ 7 - 2 × 5 =
14 + 16 ÷ 2³ - 21 ÷ 7 - 2 × 5 =
14 + 16 ÷ 8 - 21 ÷ 7 - 2 × 5 =
14 + 2 - 3 - 10 = 3
The greatest number of sets would be 20 with one girl and one boy in each.
The answer to your question is -10
Answer:
She uses 243 beads for the 5th string.
Step-by-step explanation:
In this problem, we can see a pattern. If she triples the number of beads in each of the next strings, that means that we just take the last number and multiply by 3. If the first string uses 3, then:
The second uses 9, 3 * 3 = 9
The third uses 27, 9 * 3 = 27
The fourth uses 81, 27 * 3 = 81
And the 5th uses 243, 81 * 3 = 243.
