Answer: the ordered pair is (-14,-6)

Step by step:

x – 2y = -2    (Eq. 1)

x – 4y = 10   (Eq. 2)

Isolate x in Eq. 2:

x = -2 + 2y

Substitute that solution x in Eq. 2:

x - 4y = 10

-2 + 2y - 4y = 10

Solve for y:

-2 - 2y = 10

-2y = 10 + 2 = 12

y = -6

Then calculate value for x using the above value for y

x = -2 + 2y

x = -2 + 2(-6) = -14

The solution is (x,y)=(-14,-6)

Zinaida [17]

Answer:

P = 150 - 25w

Step-by-step explanation:

Amount borrowed = $150

Repayment amount = $25 each week

P = amount Nancy owes

w = number of weeks

Amount Nancy owes = amount borrowed - repayment plan per week

P = 150 - 25w

During the first week of repayment: when w = 1

P = 150 - 25w

P = 150 - 25(1)

= 150 - 25

= 125

P = $125

Answer:

39 in²

Step-by-step explanation:

Area of triangle = 1/2 * b * h, where,

b = Base of Triangle

h = Height of triangle

Area of 4 triangles = 4 * 1/2 * 3 in * 5in

Area of 4 triangles = 2 * 3 in * 5 in

Area of 4 triangles = 30 in²

Area of square = a², where,

a = Each side of square.

Area of square = (3 in) ²

Area of square = 9 in²

Total surface area of pyramid = 30 inch² + 9 inch²

Total surface area of pyramid = 39 in²
