Use an inequality:
S = sum
7 + 7 < S < 8 + 9
14 < S < 17
so the sum is between 14 and 17
So let me give you the answer with procedure so that you can understand it better:
Let x = Number
<span>Product of 9 and Number:</span>
<span>9x </span>
<span>is 12 less than 3 times that number. So: </span>
<span>3x - 12 </span>
<span>Set them equal and solve for x like this:</span>
<span>9x = 3x - 12 </span>
<span>6x = -12 </span>
<span>x = -2
</span>I hope this is very useful for you
Segment AB and segment DE are corresponding and congruent parts
Answer:
25 miles
Step-by-step explanation:
Step one:
given data
We are told that 20 gallons of gas can go 410 miles
what we want is the number of miles that 50 gallons can go
Step two:
so
20 gallons will go 410 miles
50 gallons will go x
cross multiply
20x=50*40
divide both sides by 20
x= 500/20
x=25 miles
