Answer:
£6633.04
Step-by-step explanation:
Compound interest is worked out by using decimal multipliers on a calculator basically,
so,
6000 x 1.034 (because 3.4% = 0.034)
but you want it for three years so you would do
6000 x 1.034 x 1.034 x 1.034
hope that helped
Answer:
x < 4
Step-by-step explanation:
-8x + 2x - 16 < -5x + 7x
Put the <em>x </em>values together on both sides.
6x - 16 < 2x
Subtract the <em>6x</em> from both sides.
-16 < -4x
Divide the <em>-4x</em> from both sides.
4 > x
<u><em>(NOTICE:</em></u><em> The inequality sign flipped when we divided by a NEGATIVE number. This will always happen when multiplying or dividing by a NEGATIVE)</em>
<em />
<em>Most teachers will want the variable in front so the answer will be </em><em>x < 4</em>
<em>(</em><u><em>NOTICE:</em></u><em> The inequality sign flipped again! This happens whenever you flip the order of the numbers. Meaning, the variable on the left or right side. Usually, you will want the variable on the left side.)</em>
Answer:
The temperature rises 7 degrees between noon and 4pm.
Step-by-step explanation:
First, you add 5 to the -12. This gets you to the answer of 7. Then, since the temp. rises to 0 degrees by 4, you know that the difference between noon and 4 pm is 7 degrees.
Let the stones of each piles be x, y and z respectively.
thus, x + y + z = 376
x=x
y = x + 24
z= 2y = 2(x+24)
This becomes x + x + 24 + 2(x+24) = 376
= 4x + 24 + 48 = 376
= 4x + 72 = 376
Thus, 4x = 304
Thus, x = 76
and y = 76 + 24 = 100
and z = 2 x 100 = 200
Thus, first pile has 76 stones, second pile has 100 stones and third pile has 200 stones
