7 is the actual answer but did you know the tecnical answer is 13 when you add 1 when you subtract and when you add it is 42.
41
g/5 -13 = 42 (add 13 to both sides) g/5 = 55 (multiply both sides by 5) g = 275
3x-7+4 = 42 3x-7 = 38 3x = 45 x=15
for equations like this, it's a simple matter of remembering the order for your calculation - remember BEDMAS(Brackets, Exponents, Divide, Multiply, Add, Subtract)So for this calculation7 + 42 / 6 * 5do division first (42/6) = 7, leaving7+7*5then multiplication (7*5) = 35, leaving7+ 35 = 42
the result is always even
Multiply-Add Divide-Subtract Power-MultiplyIt's the rule for exponents.If the bases are the same and they're...- multiplied; add the exponents. 22(23) = 25- divided; subtract the exponents (36/34) = 32- raised to a power; multiply the exponents (42)4 = 48

32
multiply by 2 then subtract 6
41
42 and 43 add to 85 5 and 17 multiply to 85 170 and 85 subtract to 85 170 and 2 divide to 85
32 32
g/5 -13 = 42 (add 13 to both sides) g/5 = 55 (multiply both sides by 5) g = 275

Multiply the minutes by 60. Then add the 42 seconds.
Start at 1. Multiply by 3. Subtract 1. Multiply by 3. Subtract 1. Repeat this pattern.
