Step-by-step explanation:
Hey there!
According to the question,
Let the unknown number be x (smaller) another number be y (greater) respectively.
1st condition: One number is 7 more than twice of another number.
(i.e y = 2x+7)....... (i)
2nd condition: The sum is 22.
(i.e X+y= 22)……(ii)
From equation (ii).
x+ y= 22
x= 22-y
Putting the value of X in eqaution (I)
y = 2(22-y)+ 7
y = 44 - 2y +7
3y = 44+7
y = 51/3
Therefore, y= 17.
Now, Putting the value of y in eqaution (ii)
X = 22-y
x = 22-17
Therefore, x= 5.
Therefore, one number is 17. (Option D).

Answer: The equation is 5x = 12.50 and you will have the canoe for 2 and half hours or 2 hours 30 minutes.
Step-by-step explanation:
You rent the canoe for 5 dollars per hour and that can be represented by the expression 5x. After sometime you paid $12.50 meaning that to find the number of hours that you need the canoe, we need to set 5x to equal 12.50.
5x = 12.50 Solve for x by divide both sides by 5.
x = 2.5
This means you will need the canoe for 2 and half hours.
Answer: 14.38%
Step-by-step explanation:
Worth of stock in Company A = $5990
Percent decrease = 20%
New worth = $5990 - (20% × $5990)
= $5990 - (0.2 × $5990)
= $5990 - $1198
= $4972
Worth of stock in Company B = $2450
Percent decrease = 8%
New worth = $2450 - (8% × $2450)
= $2450 - (0.08 × $2450)
= $2450 - $196
= $2254
Previous total worth = $5990 + $2450
= $8440
Total worth = $4972 + $2254
= $7226
The total percentage decrease in the investor's stock account will be:
= [($8440 - $7226) / $8440] × 100
=( $1214 / $8440) × 100
= 0.1438 × 100
= 14.38%
