A simple way to find an equivalent fraction to
is to multiply both denominator and numerator.
So:
4 - 5x = 59
Subtract 4 from both sides:
-5x = 55
Since x is being multiplied by -5, the next step is to divide both sides by -5.
Equations for the numbers of pairs of socks (s) and handkerchiefs (h) can be written as
3s +2h = 1.45
2s +5h = 1.75
These can be solved by any of your favorite means to find
s = 3.75/11 ≈ 0.341
h = 2.35/11 ≈ .214
The price of a pair of socks and a handerchief is $0.34 +0.21 = $0.55.
A football field is 120 yards long (100 yards playing field plus 2 end zones 10 yards each) by 53 1/3 yards wide.
1 yard = 3 feet.
120 yards x 3 feet per yard = 360 feet
53 1/3 yards x 3 = 160 feet.
The area of the football fields is 360 x 160 = 57,600 square feet.
1 bag covers 2000 square feet:
57,600 / 2,000 = 28.8 bags, round up to 29 bags are needed.
1 bag cost $27.79.
29 bags x $27.79 = $805.91 total cost.
Answer:
(- 4, 1 )
Step-by-step explanation:
A translation (x + 1), y - 3 ) means add 1 to the original x- coordinate and subtract 3 from the original y- coordinate.
B = (- 5, 4 ), thus
B' = (- 5 + 1, 4 - 3 ) = (- 4, 1 )
