Answer:
77 cm²
Step-by-step explanation:
We know that
Area of trapezium = ½ (a + b) × h
Area = ½ × (10 + 12) × 7
Area = ½ × 22 × 7
Area = 11 × 7
Area = 77 cm²
Answer:
See explanation
Step-by-step explanation:
4x = 12x + 32
Subtract 12x from both sides
-8x = 32
Divide each side by -8.
x = -4
Answer:
Tuesday
Step-by-step explanation:
Let the days of the week be numbered 1–7, starting with Monday and ending with Sunday. Let <em>t</em> represent today. We can equate the number of skirts finished by Friday (day 5) with the ones finished by Sunday (day 7) at the lower rate. (days × (skirts/day) = skirts)
... (5-t)×5 = (7-t)×3
... 25 -5t = 21 -3t . . . . . eliminate parentheses
... 4 = 2t . . . . . . . . . . . . add 5t-21
... 2 = t . . . . . . . . . . . . . divide by 2
Day 2 corresponds to Tuesday.

<em>Check solution</em>
(5-2)·5 = 15 = (7-2)·3 skirts are being made.
