15% of 14.25.....turn percent to decimal..." of " means multiply
0.15(14.25) = 2.1375 rounds to 2.14....its B
a/b=5/4
a=5k
b=4k
b/c=7/3
b=7x
c=3x
b=4k
b=7x
4k=7x =>
k=7y
x=4y
a/b/c=
=5*7*y/4*7*y/3*4*y=
=35y/28y/12y=
=35/28/12y=
=5/4/12y=
=1,25/12y=
=0.1041666666666667/ y

Answer:
C) x – 2). 2 ... -2x ≤ 2. ⇔ x ≥ -1. Tập nghiệm S = {x | x ≥ -1}. Bài 2. Gọi x (km) là quãng đường
Step-by-step explanation:
<h3>The relationship between x and y is called a linear relationship because the points so plotted all lie on a single straight line. The number 95 in the equation y=95x+32 is the slope of the line, and measures its steepness.</h3>
Answer:
Step-by-step explanation:
If the speed is constant for 5 machines and produces x amount of toys we know that rate is defined as a constant per time:
Here the machines are constant and the rate is x toys per hour:
If 5 machines make x per hour:
Rate is x/1 hour
The the ratio of 8/5 is 1.6. Therefore for 8 machines the rate is 1.6 times more per hour than for5 machines. Therefore we can write an expression as:
Rate for 5 machines is x and for 8 machines is y:
