y = - x + 5
and
5x + 2y =14
Now we will have to put the value of y from the first equation in the second equation and then calculate.
5x + 2y = 14
5x + 2(-x + 5) = 14
5x - 2x + 10 = 14
3x = 14 - 10
3x = 4
x = 4/3
Now we have to put the value of x in the first equation for determining the value of y
y = - x + 5
= - (4/3) + 5
= (15 - 4)/3
= 11/3
So the value of x is 4/3 and the value of y is 11/3.

There are 5 large dogs and 3 small dogs
Solution:
Let "S" be the number of small dogs
Let "L" be the number of large dogs
Given that There are a total of 8 small and large dogs
So we can frame a equation as:
number of small dogs + number of large dogs = 8
S + L = 8 ------- eqn 1
You realize there are 2 more large dogs than small dogs
Number of large dogs = 2 + number of small dogs
L = 2 + S -------- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "L" and "S"
Substitute eqn 2 in eqn 1
S + 2 + S = 8
2S + 2 = 8
2S = 6
S = 3
Substitute S = 3 in eqn 2
L = 2 + 3 = 5
L = 5
Thus there are 5 large dogs and 3 small dogs

5 large dogs and 3 small dogs

Volume: V=lwh
Choose an appropriate length, width, and height for your package so that it can fit the product you are shipping. Using these dimensions, what is the ratio of surface area to volume?
Answers
Length = 10 inches
Width = 5 inches
Height = 8 inches
Surface area = 2lw + 2wh + 2lh
S.A = 2(10in * 5in) + 2(5in * 8in) + 2(10in * 8in)
S.A = 2(50in²) + 2(40in² + 2(80in²)
S.A = 100in² + 80in² + 160in²
S.A = 340 in²
Volume = lwh
V = 10 in * 5 in * 8 in
V = 400 in³
ratio of the surface area to volume?
340 in² / 400 in³ = 34 / 40 in = 17/20 in
Answer:
Product: Iphone 6s plus box
W= 3in L= 6in H= 3in
And then use the surface area equation ( SA = 2lw + 2wh + 2lh)
To get your volume use the equation ( V = lwh)
And then divide those two SA / V and you get your ratio
