Answer:
3 pack of hot dogs and 2 pack of buns 24
Step-by-step explanation:
hot dogs come in packs of 8
burns came in packs of 12
what is the least number of each you can buy in order to have a equal number of hot dogs and buns
so to get equal number
we have to look for the LCM of 8 and 12 = 24
therefore the packs will be equal to product
hot dogs come in packs of 8 = 8*3 = 24
burns came in packs of 12 = 12 *2 = 24
therefore, 3 pack of hot dogs and 2 pack of buns 24
Hello!
Judging by the question you have provided I came to the conclusion that to find the speed at which the student runes in feet per minutes you need to first start off by converting the distance, 50 yards, to feet.
To do this you need to use the equation 3x=y. X being yards Y being feet.
Your equation should look something like this, 3(50 Yards)= Feet, and your answer should be 150 feet.
The next step is to see the distance the student runs in feet per second. To do this you need to divide the 150 feet by 6.1 seconds.
Your answer should be 26.23 feet per second.
Lastly you now need to see the distance the student would run if they ran for a minute.
To do this you need to multiply the feet per second by 60 (one minute).
Your answer should be ~1574 feet per minute.
Hope this helped!

The answer
the full the question is as follow:
<span>Which of the following is an extraneous solution of (45 - 3x)^1/2 =x -9
for solving such an equation, this is the method:
finding the squared value of each member of the equation
</span>[(45 - 3x)^1/2 ]² = (x -9)² (E)
<span>
extend each value of the member
</span>[(45 - 3x)^1/2 ]² = 45 - 3x, because (sqrt a )² = a
the condition is 45 - 3x≥0 ( because of the square root)
it means - 3x≥ -45 and x ≤ 15
(x -9)² = x²-18x + 81
<span>
so </span>45 - 3x = x²-18x + 81, this is equivalent to x² - 15x +36 =0
<span>
this equation should solve for x, for finding the help
Delta = 15² - 4*36 = 81, so x = - (-15) - sqrt (81) / 2 *1=15-9 /2= 3
and </span>x = - (-15) +sqrt (81) / 2 *1= 15 +9/2= 24/2=12
<span>
for x= 12, the equation given above ( equation E) has no solution, because
we can find 3=9
so </span><span>an extraneous solution is x = 12</span><span>
</span>
Answer:
x=2
a=19
Step-by-step explanation:
2x+3=7
2x+3-3=7-3
2x=4
2x/2=4/2
x=2
418=-22a
418/(-22)=-22a/(-22)
19=a
