7. Easiest method is substitution. Since y=x/2, then:
2x+3(x/2)=28
8.Substituting again, we get:
3x-6x=6
-3x=6
x=-2
(-2,6)

Answer:
The answer is 
Step-by-step explanation:
The formula is:
In this case :
To get the simples form notice both 104 and 288 are divisible by 8 and 104/8 = 13 and 288/8 = 36.
Thus 
Answer:
x = 45°
Step-by-step explanation:
<u>Vertical Angle Theorem</u>
When two <u>straight lines intersect</u>, they form two pairs of angles. The vertically opposite (non-adjacent) angles are <u>congruent</u> (equal).
From inspection of the given diagram, the <u>straight line with points C and D</u> and the <u>straight line with points F and G</u> intersect at <u>point E</u>.
Therefore, angles ∠FEC and ∠DEG are vertically opposite, and so they are equal.
From inspection of the diagram:
- ∠FEC = x°
- ∠DEG = 20° + 25° = 45°
Therefore:
⇒ ∠FEC =∠DEG
⇒ x = 45°
Answer:
Step-by-step explanation:
D=√((-5+2)²+(-4+1)²)=√(9+9)=3√2≈4.24
The required a) assessed value = $21600,
b) tax rate = 0.0855,
c) real estate tax = $1836.
<h3>What is cost price?</h3>
Cost price is that price for buyer which he pays to seller for an object or product.
a) assessed value = 72000 x 30/100
= $21600
b) tax rate = 85.5/1000
= 0.0855
c) real estate tax = 0.855 x 21600
= $ 1836
Thus, the required values of a) assessed value, b) tax rate as a decimal, and c) real estate tax is $21600, 0.085 and $1836 respectively.
