Answer:
b=9
(assuming you meant -6x) x = -2
h = -4
a = 6
Step-by-step explanation:
40% of 250 is 250 × 40/100 = 25 × 4 = 10
Answer:
126 was removed.
Step-by-step explanation:
The total before division took place was
Total = mean * 14
mean = 49
Total = 49 * 14
Total = 685
Now you subtract x from the total
685 - x
And divide by 13 [one number is missing]
(685 - x)/13
and the result = 43
(685 - x ) / 13 = 43 Multiply both sides by 13
685 - x = 43 * 13
685 - x = 559 Subtract 685 from both sides
- x = - 126 Multiply by - 1
x = 126
Answer: a) x < 3
b) 3, 4, 5, 6
c) x > 6
<u>Step-by-step explanation:</u>
First you need to understand the symbols:
< means less than (represented by an open dot, left arrow)
≤ means less than or equal to (represented by a closed dot, left arrow)
> means greater than (represented by an open dot, right arrow)
≥ means greater than or equal to (represented by a closed dot, right arrow)
a) We have a closed dot and a left arrow so we need to use <
We write this inequality as: x < 3
b) y is BETWEEN 2 and 6 (not including 2 but including 6)
2 <u> </u><u>3 </u> <u> 4 </u> <u> 5 </u> 6
c) 3x + 7 > x + 19
2x + 7 > 19 subtracted x from both sides
2x > 12 subtracted 7 from both sides
x > 6 divided both sides by 2
Answer:
Step-by-step explanation:
Base, b = 1/3
Height, h = 12feet = (12x 0.305)metres = 3.66m
Area of triangle= 1/2 bxh
A = 1/2 x 1/3 x 3.66
A = 0.61m^2
Or in feet's
Area of triangle = 1/2 bxh
A = 1/2 x 1/3 x 12 =2 feet^2
