To get to 86 by only using 10's and 1's you count by 10, 8 times and count by 1, 6 times.
Answer:
putting value of m and n in the equation we get
10x5+ 4x2
= 50+8=58
Answer:
x = 19
Step-by-step explanation:
A circle has a total of 360 degrees. Because central angles are congruent to the degree measures of their arcs, and because of vertical angles we can construct the equation :
5x+37+5x+37+3x-9-9=360
We can simplify this to :
8x+28=360
Subtract 28, divide 8, and x is 19
318.50 x .30 = 95.55 discount.
318.50 - 95.55 = 222.95 is the total bill
