Answer:
10 is greater because the square root of 20 is 4.47
Step-by-step explanation:
The multiplier for decreasing by 45% is 0.55
So you times the multiplier by the price to get your answer:
650 x 0.55 = $357.50
Answer:
246
Step-by-step explanation:
i got it right on my test
Since BD bisects angle ABC, that means angle ABD and angle CBD are equal to each other. With that set up the equation to solve for x like this:
-4x+33 = 2x+81
-2x -2x
————————
-6x +33 = 81
-33 -33
————————
-6x = 48
————- (divide by -6)
-6
x = -8
Now substitute that to ABD
-4(-8) +33
32 +33
=65
here’s CBD
2(-8) + 81
-16 + 81
=65
Finally angle ABC will be double the amount of ABD or CBD so 65 times 2 is 130.
ANSWERS: (angles)
ABD and CBD: 65
ABC: 130
