The answer will be 16 because you multiply then add

Ok so, the "P" stands for parentheses, the "E" stands for exponents, orn^{n}. the "M" stands for multiplication, the "d" means you divide, the "a" means you add, and the "s" means you subtract. So, for question number 5, you would do  2x6 because there is no exponents or parentheses, so 2x6=12. Then you would add the 12 and the 4 together, so 12+4=16. Your answer is 16.

T=2π√l/g. Make l subject of the formula​
Aliun [14]

Answer:

l = gt²/(2π)²

Step-by-step explanation:

if  T = 2π√l/g

squaring both sides

(T)² = (2π)² × (√l/g)²

T² =4π² × l/g

T² = 4π²l/g

using cross multiplication techniqes

gT² =  4π²l

divede both sides by " 4π²"

gT²/4π² =4π²l/4π²

gT²/4π² =l

l = gT²/(2π)²

that is the final answer.

Select the correct answer.

Answer:

c.

\frac{5}{4} x - 2 = \frac{3}{2} x-4

Step-by-step explanation:

a.

\frac{5}{2} x +\frac{7}{2} =\frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14-\frac{7}{2} \\\frac{10-3}{4} x =\frac{28-7}{2} \\\frac{7}{4} x =\frac{21}{2} \\x = \frac{21}{2} * \frac{4}{7} = 6 \\

b.

\frac{5}{4} x -9 = \frac{3}{2} x-12 \\\frac{5}{4} x - \frac{3}{2} x= -12 + 9 \\\frac{5-6}{4} x = -3 \\\frac{-1}{4} x = -3 \\x = -3 * -4 \\x = 12

c.

\frac{5}{4} x-2=\frac{3}{2} x-4 \\\frac{5}{4} x-\frac{3}{2} x=-4+2 \\\frac{5-6}{4}x=-2 \\\frac{-1}{4} x = -2 \\x = -2 * -4 \\x = 8

d.

\frac{5}{2} x -7 = \frac{3}{4} x+14 \\\frac{5}{2}x -\frac{3}{4} x=14+7 \\\frac{10-3}{4} x =21 \\\frac{7}{4} x =21 \\x = 21 * \frac{4}{7} = 12 \\

You could also replace x for 8 in every equation and see if both sides give the same answer
