B. Bc rows are horizontal while columns are vertical.
Answer:
4 divided by 2/3 (4 ÷ 2/3) = 6
Step-by-step explanation:
When you divide one number by another , this is the same as multiplying that one number by the reciprocal of that other number. So a/b = a × 1/b = a × b^-1.
Also a reciprocal is the same as taking something to the power of -1.
When you take the reciprocal of a fraction, just flip the numerator, and denominator.
b^-1 = 1/b.
b^-n = 1/b^n.
(a/b)^-1 = b/a
a/b^-1 = ab
Therefore 4 / (2/3) = 4 × 3/2 = 12/2 = 6.
Step-by-step explanation:
2x - 5 = 7
2x = 7 + 5
2x = 12
x = 12 / 2
x = 6

Answer:
30
Step-by-step explanation:
The perimeter of this rectangle is calculated by adding width to length and that multiplied by 2
2*(3x+2x+2) = 54 do inside the parenthesis first
2*(5x+2) = 54 multiply inside the parenthesis by 2
10x + 4 = 54 subtract 4 from both sides
10x = 50 divide both sides by 10
x = 10
The length for PS is 3x
3*10 = 30
