Hello!
The sum of the intern angles of a triangle is 180°. If an angle is obtuse (bigger than 90°), the sum of the others must be less than 90 degrees. Letter a).
Hugs!
Input m = -4 n = 2 and p = 1.5 into the expression above
7m + 2n - 8p/n
= 7(-4) + 2(2) - 8(1.5)/2
= -28 + 4 - 6
= -30
so we have 3 folks painting 4 walls, now each one of them works for 32 minutes
person 1............. 32 mins
person 2............. 32 mins
person 3............. 32 mins
for a total of 32+32+32 = <u>96 minutes worth of work</u>. That's for 4 walls, how many minutes worth is just 1 wall?
96 ÷ 4 = 24 mins.
so to paint a wall, it takes 24 mins of work worth.
so then, to paint 7 walls, that'd be 7 * 24 = 168 minutes worth of work.
what about for 4 folks doing it? How many times does 4 go into 168? 168 ÷ 4 = 42 mins.
Answer:
x = 72
Step-by-step explanation:
Start by multiplying 16 to both sides
16s on the left-hand cancel
we can simplify that expression
