Answer:

x = 20

Step-by-step explanation:

x + 2x + (x + 10) = 90° (right angle)

x + 2x + x + 10 = 90

Add like terms

4x + 10 = 90

4x = 90 - 10 (substraction property of equality)

4x = 80

x = 80/4 (division property of equality)

x = 20

Gabe drove 124 miles in 150 minutes. find Gabe's speed in kilometers per hour. HELP PLEASE FOR MY TEST TMMRW

First, you need to convert the minutes into hours, to do this you divide the minutes by 60 (the amount of minutes in an hour). Once you've gotten the value (which is 2.5), you divide that by the amount of miles drove, then you get the unit rate, or in other words the kilometers per hour, which equals 49.6 km/h

Answer:

$\chi^2 = \frac{(83-90)^2}{90} +\frac{(68-72)^2}{72}+\frac{(85-78)^2}{78}+\frac{(64-60)^2}{60} = 1.66$
