azamat3 years ago
4 0

Answer:

Value of z = 7

Value of y = 30  

Step-by-step explanation:

We are given the following equations in the question:

y = 9 + 3z\\y = 65 -5z

We have to solve the given equation for y and z.

Equating the two equations we get,

y = 9 + 3z\\y = 65 -5z\\9 + 3z = 65-5z\\3z + 5z = 65-9\\8z = 56\\\\z = 7\\y = 9+3(7) = 30

Value of z = 7

Value of y = 30

I want to fence in a square vegetable patch. The fencing for the east and west sides cost $7 per foot, and the fencing for the n
Bezzdna [24]

The total cost of the fencing is a function of the length of a side x (feet) is  10x + 14y.

<h3>How to find the perimeter?</h3>

The perimeter is made by adding the south, north, east, and west side.

Given that

The cost of fencing for the east and west sides is $7 per foot, and the cost of fencing for the north and south sides is only $5 per foot.

We have to find total cost of the fencing is a function of the length of a side x (feet).

The east and west fencing cost is $7/ft but the south and north fencing cost is $5/ft.

x = north and south fencing

y = the east and west sides, then you can get this equation.

Total cost= (south +north) × 5 + (east+ west) × 7

Total cost =(x + x) × 5 + (y+ y) × 7

Total cost = 5(2x) + 7(2y)

Total cost = 10x + 14y

Hence, the total cost of the fencing is a function of the length of a side x (feet) is 10x + 14y.

Find each missing angle measure
timurjin [86]

Answer: angle 1=129 degrees

Step-by-step explanation:

180 - 99 - 30 = 51

all the angles of a triangle should add up to be 180 degrees

51+99+30=180

angle 1 is supplementary to the angle that is 51 degrees so it would be 129 degrees. 180-51=129
