Answer:
85 cents
Step-by-step explanation:
Let a represent the price of pineapples
Let p represent the price of peaches
74p + 9a= 14p + 21a
p = 17 cents
Substitute 17 for p
74(17) + 9a = 14(17) + 21a
1258+9a= 238+21a
1258-238= 21a-9a
1020= 12a
a= 1020/12
a= 85
Hence the price of pineapples is 85 cents
Answer:
2x+10 = 2(x+5)
5x-15 = 5(x-3)
8x+6 = 2(4x+3)
12x-8 = 4(3x-2)

Step-by-step explanation:
Answer:
A = 57.97 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 6.2, a = 10.8 and b = 7.9, thus
A = × 6.2 × (10.8 + 7.9) = 3.1 × 18.7 = 57.97 cm²
It’s the second one it’s right
