Answer:
1
Step-by-step explanation:
5% × 20 =
(5 ÷ 100) × 20 =
(5 × 20) ÷ 100 =
100 ÷ 100 =
1
When x = -3 y = -5
When x = -1 y = -1
When x = 0 y = 1
When x = 2 y = 5
Answer:
<h2>x = 3.1</h2>
Step-by-step explanation:
<h3>
</h3>
<u>To solve first take logarithm to both sides</u>
That's
<h3>
</h3><h3 /><h3>
</h3>
But
<h3>
</h3>
So we have
<u>Write 1200 as a number with the factor 100</u>
That's
1200 = 100 × 12
So we have
<h3>
</h3>
<u>Using the rules of logarithms</u>
That's
<h3>
</h3>
Rewrite the expression
That's
<h3>
</h3><h3 /><h3>
</h3><h3>
</h3><h3>
</h3><h3 /><h3>
</h3>
x = 3.079
So we have the final answer as
<h3>x = 3.1 to one decimal place</h3>
Hope this helps you
Answer:
as mentioned above we have to solve it by cross multiplication.
Step-by-step explanation:
So,
4(3x-3)=5(2x-2)
12x-12=10x-10
12x-10x=-10+12
2x=2
X=2/2=1 Answer
hope it helps!!
Tires:
65(2) - 45(2) = 130 - 90 = $40 profit
Rims:
126(3) - 85(3) = 378 - 255 = $123 profit
Headlights:
15(5) - 5(5) = 75 - 25 = $50 profit
Total profit:
$40 + $123 + $50 = $213 profit
