5 + 12 + 3 + 4 + 3 = $27
Multiply $27 by five because he bought five of those lunches, and that equals a total of $135. That's an expensive lunch! :)
Answer:
59.
Step-by-step explanation:
I´m pretty sure the answer is 59. If I´m wrong then sorry.
You can apply the Pythagorean theorem:
a^2 + b^2 = c^2
c is the longest side of the triangle
2.2^2 + 4.2^2 = 6.7^2
4.84 + 17.64 = 44.89
22.48 =/= 44.89
That is not a right triangle
42. Because you divide into 6 and 7. 6 is divided into 3 and 2. So, 2 times 3 times 7.
Answer:
20 minutes on the stationary bike
10 minutes on the treadmill
Step-by-step explanation:
x = minutes on bike
y = minutes on treadmill
x + y = 30
12x + 15y = 390
x = 30-y
12(30-y) + 15y = 390
360 - 12y + 15y = 390
3y = 30
y = 10
x + 10 = 30
x = 20
