Answer:

x:hot dogs

y: hamburger

5x + 2y = 11.75

2x + 5y = 11.00

10x + 4y = 23.50

-10x - 25y = -55.00

-21y = -31.50

y = $1.50 each hamburger

2x + 5(1.50)= 11.00

2x + 7.50 = 11.00

2x = $3.50

x = $1.75 each hot dog

max2010maxim [7]

Answer:

A

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor.

(2x + 5)(4x + 4)

= 2x(4x + 4) + 5(4x + 4) ← distribute both parenthesis

= 8x² + 8x + 20x + 20 ← collect like terms

= 8x² + 28x + 20 → A

aniked [119]

Answer:

b $3,272.43

Step-by-step explanation:

A = p(1+r/n)^nt

Where

A= future value

P= principal = $2500

r= interest rate = 6.75% = 0.0675

n = number of periods = 12

t = time = 4 years

A = p(1+r/n)^nt

= 2500(1+0.0675/12)^12*4

= 2500(1+0.005625)^48

= 2500(1.005625)^48

= 2500(1.3089737859257)

= 3272.4344648144

Approximately

A= $3272.43

He will have $3272.43 to give as down payment in 4 years
