Answer:
28.3
Step-by-step explanation:
12/20 = 17/x
cross multiply
12x=340
divide each side by 12
x=28.3333333333.......
round it to nearest tenth
28.3
Answer:
x = 6 m
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 A = 60, h = 8, a = 9 and b = x , thus
× 8 × (9 + x) = 60, that is
4(9 + x) = 60 ( divide both sides by 4 )
9 + x = 15 ( subtract 9 from both sides )
x = 6 m
Product means the answer/result to a multiplication problem
Estimate means to form an approximation/ rough guess
126.12 x 2.2 = 277.464
This answer, 277.464, is the exact product
Its wanting us to find the estimate (there could be possible estimates, depending on what the instructions is asking for):
- 277
- 280
- 300
