They are acute angels cause there smaller than 90
0.85x=200
then x=200/0.85 (u can write 0.85 to 85/100) fraction decimal form
x=4000/17
solve it
7/6x=140
1/x=20*6
1/x=120
x=1/120
Answer:
7x² - 6x + 4
Step-by-step explanation:
(4x² - x + 6) - (-3x² + 5x + 2)
4x² - x + 6 + 3x² - 5x - 2
4x² + 3x² - x - 5x + 6 - 2
7x² - 6x + 4
If there are choices, then you need to choose the correct choice, but if there are no choices, then one correct answer is to multiply the first equation by -2 and add it to the second equation to eliminate x and solve for y.
