Answer:
C
Step-by-step explanation:
BECAUSE I DIDID IT IN EDGENUTITHALD
1 hour is equivalent to 60 minutes
3/4 hours is - 60 minutes x 3/4 = 45 minutes
3 hours are equivalent to 60 minutes/hr x 3 hr = 180 minutes
it takes Cindy 45 minutes to complete a puzzle
so it takes her 45 minutes for - 1 puzzle
then in 180 minutes she can make - 1/45 x 180 = 4 puzzles
in 3 hours she can complete 4 puzzles
Answer:
x = -3.2
Step-by-step explanation:
−7.8(x+6.5)=−25.74
Divide each side by -7.8
−7.8/-7/8 *(x+6.5)=−25.74/-7.8
x+6.5 =3.3
Subtract 6.5 from each side
x+6.5-6.5 = 3.3-6.5
x = -3.2
5+(8²-2) *2
Here we will use PEMDAS rule.

Step 1:
P- parenthesis first.
(8²-2)
E- exponents
8² = 8*8 =64
subtracting 64-2 = 62
5 + 62*2
Step 2:
Multiplication and division.
multiplying 62 *2 = 124
5+124
Step 3:
Addition: adding 5+124
129
