Answer:
Case I
$115
Case II
$125
Step-by-step explanation:
Bugles rent for $10 per month
Drums rent for $5 per month
Case I
7 bugles and 9 drums
7 * bugle cost per month + 9 * drum cost per month
7 * 10 + 9* 5
70 + 45
$115
Case II
9 bugles and 7 drums
9 * bugle cost per month + 7 * drum cost per month
9 * 10 + 7* 5
90 + 35
$125
Answer:
So that means length of the bike is approx 5.7 rulers.
Step-by-step explanation:
the question says to estimate how many 12-inch rulers will be about the same length as a bike. In other words we have to measure the length of bike by in terms of ruler like 3 ruler length or 5 rular length etc.
Type of bike is not mentioned so i'm going to use bicyle.
From internet I found that approx lenght of a bike ( bicycle) is = 68 inches.
Given that 1 ruler = 12 inches
So number of rulers that can fit into 68 inches can be found by dividing 68 by 12
68/12 = 5.7
Since each odd (or even) is two greater than the previous number, two consecutive such numbers are n and n+2.
The we are told that the sum of two such number is 100, so we can say:
n+n+2=100 combining like terms on the left side you get:
2n+2=100
....
to solve, if you were interested...subtract 2 from both sides
2n=98 divide both sides by 2
n=49
So the two odd numbers are 49 and 51
Your answer would be x=8
4=√2x ( switch the sides )
√2x=4 ( square both sides )
2x=16 ( divide both sides by 2 )
x=8
