First you have to find how much each stamp costs. So u take 2.20 ÷ 5 = 0.44.
Next you take 0.44 x 7 and you should get $3.08

First, divide 2.20 by 5 to find the price of a single stamp.
2.20 ÷ 5 = 0.44
One stamp cost $0.44
Now, you multiply this by 7 to find the cost of seven stamps.
0.44 × 7 = 3.08
In 2012, seven stamps cost $3.08

Write an expression in factored form for the polynomial of least possible degree graphed below.
dexar [7]

Answer:

- 1/64 (x+4)² (x-3) (x-4) = 0

Step-by-step explanation:

f(x) = a (x+4)²(x-3)(x-4)   ... curve touch (-4,0) and not cross x axis

x=0   f(x) = -3

a (4)² * (-3) * (-4) = -3

a = - 1/64

- 1/64 (x+4)² (x-3) (x-4) = 0

Solve the system of linear equations by substitution.<br> 2x-y=3<br> x+5y=14
Arturiano [62]

Answer:

x= 29/11 or y= 25/11

Step-by-step explanation:

2x - y= 3 ...........equation 1

x + 5y= 14 ............equation 2

Make x the subject of the formula in equation 2

x= 14 - 5y ..............equation 3

Substitute x=14 - 5y in equation 1

2(14- 5y) - y=3

28 - 10y - y=3

Collect like terms

-10y - y=3 - 28

-11y= -25

divide both sides by coefficient of y

-11y/-11 = -25/-11

y= 25/11

Substitute y= 25/11 in equation 3

x=14 - 5(25/11)

x= 14 - 125/11

x= 29/11
