Let d = number of stamps from John (4 letters, d is 4th letter, etc)
<span>Let e = number of stamps from Johan </span>
<span>Let h = number of stamps from Jonathan </span>
<span>Johan and Jonathan have the same number of stamps, so: </span>
<span>e = h </span>
<span>2 times Johan's collection is 11 less than 5 times John's collection, so: </span>
<span>2e = 5d - 11 </span>
<span>3 times Jonathan's collection is 3 less than 7 times John's collection,so: </span>
<span>3h = 7d - 3 </span>
<span>Now we have three equations and three unknowns. You're asked for the number of stamps in John's collection, so you want the value to variable "d". </span>
<span>Since e = h, we can substitute "h" for "e" in the second equation. </span>
<span>2h = 5d - 11 </span>
<span>3h = 7d - 3 </span>
<span>now we have two equations and two unknowns. I'll use elimination, starting with multiplying the first equation by -3 and the second one by 2. </span>
<span>-6h = -15d + 33 </span>
<span>6h = 14d - 6 </span>
<span>now add both together and you have an equation with one unknown remaining: </span>
<span>0 = -d + 27 </span>
<span>d = 27 </span>
<span>So your answer is 27 stamps. If you want to know how many stamps the others have, you can work back and solve for e and h.</span>
Answer:
Kristen has only 1 quart of water more than him
Step-by-step explanation:
Since 1 gallon equals 4 quarts you would multiply...
1gallonx7,4 quarts x 7= 7 gallon and 28 quarts
Next thing to do si subtract you will do that by subtracting 27 quarts that are from mike from the 28 quarts that are from kristen. the result is 1 quart more

Answer: There are 20 problems on the test.
Step-by-step explanation:
Since we have given that
Patricia scored 80% on a math test.
She missed 4 problems.
So, 20% of the math test is equal to 4 problems.
Let the total number of problems on the test be x
According to question,
Hence, there are 20 problems on the test.
