What expression completes the equation to determine the total amount of minutes Marni danced? How many minutes did Marni dance? Enter the answers in the boxes.
2 answers:
Total raised: 264
She raised 30 plus 1.80x (x being the number of minutes).
Equation: 264=1.8x+30
To solve for x, you need to isolate x. First, subtract 30 from both sides.
234=1.8x
Now, divide both sides by 1.8.
130=x
Marni danced 130 minutes.
I hope this helps :)
Hi Caden,

Subtract 30 from 264
264 - 30 = 234
Now Divide
234 / 1.8 = 130

Answer:
x = 60
largest angle = 80°
Step-by-step explanation:
the sum of all three angles in a triangle = 180°
(3x - 100) + (x - 10) + (x - 10) = 180
simplify:
5x = 300
x = 60
angles are 80°, 50°, and 50°
