inessss [21]

Answer:

$1.6\cdot{x}$

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:

$y=1.6\cdot{x}$

pickupchik [31]

Answer:

1 1/30 gallon

Step-by-step explanation:

Can A = 1/3 gallon

Can B = 1/5 gallon

Can C = 1/2 gallon

Total paint Neil has = Can A + Can B + Can C

= 1/3 + 1/5 + 1/2

The lowest common multiple of 3, 5 and 2 is 30

= (10+6+15) / 30

= 31/30

= 1 1/30 gallon of paint

Neil has a total of 1 1/30 gallon of paint

$x \geq 4y$

$7.50x+4.75y\leq 125$

$x > 0$

$y > 0$

Step-by-step explanation:

Let

x -----> the number of yellow rose bushes

y -----> the number of red rose bushes

we know that

At least means "greater than or equal to"

$x \geq 4y$ ----> inequality A

$7.50x+4.75y\leq 125$ -----> inequality B

additionally

The number of roses cannot be a negative number

so

$x > 0$ ----> inequality C

$y > 0$ ----> inequality D

therefore

The restraints are

$x \geq 4y$

$7.50x+4.75y\leq 125$

$x > 0$

$y > 0$
