Answer:
x = 109
Step-by-step explanation:
The figure has one pair of parallel sides and is a trapezoid.
The lower base angle is supplementary to the upper base angle on the same side, thus
x + x - 38 = 180 , that is
2x - 38 = 180 ( add 38 to both sides )
2x = 218 ( divide both sides by 2 )
x = 109
Answer:
1.6
Step-by-step explanation:
35/22 = 1.59
round the decimal to the tens place, or the number right after the decimal
16 cups=1 gallon
16 cups x 4 gallons = 64 cups
1 cup per minute = 64 minutes
64 minutes = 1 hour and 4 minutes
Let d and q be the number of dimes and quarters respectively.
10 cents* d+ 25 cents* q = 620 cents ($6.20 = 620 cents)
⇒ 10d + 25q = 620 (1)
On the other hand, we have: d+ q= 32 (coins) (2)
From (1) and (2), we solve the set of equations.
The final answer is d= 12 coins and q= 20 coins.
