10,000,000 + 2,000,000 + 400,000 + 30,000
Answer:
x = 
Step-by-step explanation:
Note that 
= 14
Expressed in exponent form as
= 14, thus
x =
Answer:
44
Step-by-step explanation:
The two base angles cannot both be 92 degrees because they would add up to 184 which is more degrees than any triangle has. The apex angle (the top angle) therefore has 92 degrees.
The base angles are equal and found as follows.
2*b + 92 = 180 Subtract 92 from both sides
2b +92-92 = 180-92
2b = 88 divide by 2
2b/2=88/2
b = 44
The only angle measurement that fits is 44
Step-by-step explanation:
- you just substitute (-2) into the x values of the above function
100*2.2=220
80*2=176
220+176=396
So the two trains will take 2.2 hours so that they are 396 miles apart.
