Answer:
25x^2 - 16y^2 - 400 = 0
Step-by-step explanation:
First, distribute the 100 to the (x-1) portion:
500 = 100x - 100
then, add 100 to both sides of your equation to get “x” alone on the right side:
500 + 100 = 100x - 100 + 100
600 = 100x
next, divide 100x by 100 and 600 by 100 to isolate a singular “x”:
600/100 = 100x/100
6 = x
therefore, x=6 is your solution

Answer: i'm pretty sure the first option is correct. she wrote it down correctly
Answer:
30°,40°
Step-by-step explanation:
let the other angles be 3x and 4x
3x+4x+110=180
7x=180-110=70
x=70/7=10
3x=3×10=30
4x=4×10=40
