Answer:
Commutative Property for Multiplication
Answer:
25.9 miles
Step-by-step explanation:
To find out how far he can go on one gallon of gas, we divide miles by gallons.
311 miles/ 12 gallons
25.91666666 miles per gallon
So on one gallon of gas, he can go 25.9166666666 miles
Rounding to the nearest tenth.
25.9 miles
B
rearrange into standard form : ax² + bx + c = 0 (a≠ 0)
2x² - 3x - 2 = 0
(x - 2)(2x + 1) = 0 ( equate each factor to zero and solve for x )
x - 2 = 0 ⇒ x = 2
2x + 1 = 0 ⇒ x = - 0.5
Answer:
A) 4.5
Step-by-step explanation:
you can set up a ratio comparing AB/CB to (AB + BD)/5
3/2 = 3 + BD/5
cross-multiply to get 15 = 2(3 + BD)
15 = 6 + 2BD
9 = 2BD
9/2 = BD
