Answer:
23
Step-by-step explanation:
area of a trapezoid = 1/2 × (a + b) × h
so, we have
96 = 1/2 × ((4x - 1) + (x + 3)) × 6 = (5x + 2) × 3
32 = 5x + 2
30 = 5x
x = 6
a = 4x - 1 = 4×6 - 1 = 24 - 1 = 23
Answer:
y = (2/3)x + 1.5
Step-by-step explanation:
To get our equation, we must first convert our values from inches to feet.
8/12 = 2/3 or 0.666667...
18/12 = 3/2 or 1.5
Now that we have our inches converted to feet, we can plug our values into the equation y = m(x) + b.
A = 21
b = 3
c = 1.3? not sure
d = 8
Let they be x.
Cost of textbooks + laptops cant greater than total amount.
(cost of 1 textbooks * number of textbooks) + (cost of 1 laptop * number of laptops ≤ 6500
(30*116) + (x*439) ≤ 6500
3480 + 439x ≤ 6500
439x ≤ 3020
x ≤ 6.8(approx)
Last natural number is 6, says, they can buy 6 laptops at max.
The Answer to this solution is -14r
