Answer:
p = 35
Step-by-step explanation:
( 2p + 5 ) + ( 3p ) = 180
-
2p+5+3p=180
Combine 2p and 3p to get 5p.
-
5p+5=180
Subtract 5 from both sides.
-
5p=180−5
Subtract 5 from 180 to get 175.
-
5p=175
Divide both sides by 5.
p = 175\5
Divide 175 by 5 to get 35.
-
p = 35

Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
so plug in x into the function h(x) to get h(x)
h(x) means x in terms of h, you can also think of this as "y"
so at x = -1, y = -2
so,
h(-1) = -2
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>
$2.75. you have to divide how much it costs with how many lbs. That would show u how much one costs
