Answer:
You are right, it's B
Step-by-step explanation:
Complementary angles are angles that add up to 90 degrees.
Answer:
b. x = 11/8, x = 59/72.
Step-by-step explanation:
4|8x - 6| = 5|-8x + 7|
square both sides:
16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)
1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0
576x^2 - 1264x + 649 = 0
x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)
x = 11/8, x = 59/72.
The answer is 12.6
419 is 420 because we are estimating so find 1% of 420 which is 4.2 then multiply 4.2×3 to get 12.6
Answer:
5x +2x+14 =14x-7
7x+14=14x-7
14+7=14x-7x
21 divide bye 7=7x divide bye 7
3=x
