2x+2x+60=180 because the angles have to add up to 180
So you have
4x+60=180
4x=120
x=30
Is there a picture to this
Answer:
x = 3 ±sqrt(6)
Step-by-step explanation:
6(x-3)^2-26 = 10
Add 26 to each side
6(x-3)^2-26+26 = 10+26
6(x-3)^2 = 36
Divide by 6
6/6(x-3)^2 = 36/6
(x-3)^2 = 6
Take the square root of each side
sqrt((x-3)^2) = ±sqrt(6)
x-3 = ±sqrt(6)
Add 3 to each side
x-3+3 =3 ±sqrt(6)
x = 3 ±sqrt(6)
Answer:
40 problems in 100 minutes
Step-by-step explanation:
This is a ratio problem.
You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.
That function is incorrect.
The correct function is . . . . C(f) = (5/9) (f - 32) .
If a Fahrenheit thermometer reads 52° ,
then a Celsius thermometer should read . . .
C (52) = (5/9) (52 - 32) =
(5/9) (20) = <em>(11 and 1/9)°C</em>.
