Step-by-step explanation:
x-number of stuffed animals
7:16
Dolls:All the toys
7:7+x

x=9
Answer:
The answer to your question is
Step-by-step explanation:
Data
4x - 8y = -16 ------------ (I)
x - 2y = - 8 ------------ (II)
a) Solve equation II for x
x = 2y - 8
Substitute x in equation I
4(2y - 8) - 8y = -16
8y - 32 - 8y = -16
8y - 8y = 32 - 16
0 = 16 The system has no solution because y was
cancelled.
b) When a system of equations do not have solution means that the lines are parallels and different.
<h3>Henry drove the truck for 208 miles</h3>
<em><u>Solution:</u></em>
Given that,
Base fee = $ 18.95
Additional charge of $.79 for each mile driven
Let "x" be the miles driven
Henry had to pay $183.27 when he returned the truck
Therefore,
Cost for rent = base fee + charge for "x" miles
183.27 = 18.95 + 0.79x
0.79x = 183.27 - 18.95
0.79x = 164.32
Divide both sides by 0.79
x = 208
Thus Henry drove for 208 miles the truck
Add the gain and the last weight together
new weight = 6 3/4 + 1 1/2
or we can write it as
new weight = 6 + 3/4 + 1 + 1/2
Separate whole numbers and fraction
new weight = 6 + 3/4 + 1 + 1/2
new weight = 6 + 1 + 3/4 + 1/2
Simplify the whole numbers
new weight = 6 + 1 + 3/4 + 1/2
new weight = 7 + 3/4 + 1/2
Equalize the denominators of the fraction
new weight = 7 + 3/4 + 1/2
new weight = 7 + 3/4 + 2/4
new weight = 7 + 5/4
Because 5/4 is improper fraction, change it to mixed fraction
new weight = 7 + 5/4
new weight = 7 + 1 1/4
new weight = 7 + 1 + 1/4
new weight = 8 + 1/4
new weight = 8 1/4
The cat weights 8 1/4 pounds now
