It’s an isosceles triangle, so those two sides are equal:
3x-15=x+33
2x=48
x=24, so BC should be 24.
Answer:
The answers to your questions are given below
Step-by-step explanation:
A. 3 × 9 = 27
B. 2 × 3 × 9 = 54
Next, we shall determine which option will give the same result obtained above.
9 × 3 = 27
9 × 3 × 2 = 54
3 × (4 + 5) = 3 × 9 = 27
(2 × 3) × 9 = 6 × 9 = 54
Therefore,
3 × 9 = 27
9 × 3 = 27
3 × (4 + 5) = 27
2 × 3 × 9 = 54
9 × 3 × 2 = 54
(2 × 3) × 9 = 54
SUMMARY
3 × 9 >>>>>>>>> 2 × 3 × 9
9 × 3 >>>>>>>>> 9 × 3 × 2
3 × (4 + 5) >>>>> (2 × 3) × 9
Answer:
2.4 *103 = 247.2
1.5*103 = 154.5
3.6*106 = 381.6
3.9*106 = 413.4
3.6*109 = 392.4
3.9*109 = 425.1
Step-by-step explanation:
2.4 * 103
we firstly count decimal numbers
in the calculation
only 2.4 has a decimal and only one number after the point
so we keep it aside making
2.4 = 24 1 dp (decimal place)
back to the calculation
1 0 3
* 2 4
----------
4 1 2
2 0 6
-------------
2 4 7 2
-------------
don't forget we still have a dp !
so we place the point 1 step backward
2472 to 1dp =
247.2
with this we can solve orders
11/16
Explanation: we have 16 marbles in total and 11 red and blue marbles, so the probability is 11/16!
Answer:
the man is 52 years old
Step-by-step explanation:
man: 35+x
son:x
y=884/x
x(35+x)=884
35x+x^2=884
35x+x^2-884=884-884 . 884/-17+52=35
x^2+35x-884=0
(x-17)(x+52)=0
x=17 . x=-52 (age can't be negative)
man:35+17=52
