You have the ratios set up but you need to cross multiply everything:
(5x + 10) x 11 = 121 x 10
55x + 110 = 1210
Subtract 110 from both sides:
55x = 1100
Divide both sides by 55:
X = 1100 / 55
X = 20
Answer:
I think its D. A triangle thats obtuse cant be equal because one of the angles has to be over 120°.
Answer:
420 students
Step-by-step explanation: I first did 300/5 which got me 60, meaning that one bus could transport 60 students. Then you do 60*7 (60 is how many students on each bus, and 7 is how many buses there are) and get 420 students on 7 buses.
Substitute x to be 7 (for month 7) and work out the equation:
y = -13(7) + 111
y = -91 + 111
y = 20
Your answer is 20 degrees Fahrenheit.
Answer:
A
Step-by-step explanation:
given
16x² + 4 = 0 ( subtract 4 from both sides )
16x² = - 4 ( divide both sides by 16 )
x² =
= - 
[ take the square root of both sides ]
x = ±
= ±
i (
= i )
