Is (2,3) a solution to the system of inequalities 4x+3y<20 <br> 10x+y>10

stiks02 [169]

Yes it is a solution because if you take the equation and plug the point in for the x and y :

4 (2) + 3 (3) < 20
8 + 9 < 20
17 < 20
which is true

10 (2) + (3) > 10
20 + 3> 10
23>10
which is also true

A city held a bike parade. 52 bikers rode in the parade, and 8 of them rode a fixed-gear bicycle.

Vedmedyk [2.9K]

Answer:

$\frac{2}{13}$

Step-by-step explanation:

Find the probability by dividing the number of fixed gear bikers by the total number of bikers in the parade.

Since there are 8 fixed gear bikers and 52 bikers in total, this will be found by dividing 8 by 52.

So, the probability as a fraction is $\frac{8}{52}$

This can be simplified by dividing both the numerator and denominator by 4:

= $\frac{2}{13}$

So, the probability is $\frac{2}{13}$

On the blueprint of a house, 40 millimeters represents 6 meters. The length of the living room is 50 millimeters on the blueprin

Novay_Z [31]

Answer:

Convert the meters to millimeters

1m = 1000mm

6m = 6000mm

40mm represents 6000mm

Find the scale factor

6000/40 = 150

This means 40 * 150 = 6000

Yup find what 50mm represents:

50 * 150 = 7500

7500mm

7.5m
