Answer:
Jackie sold 12 cars.
Step-by-step explanation:
If we call the number of cars Oscar sold O, and the number of cars Jackie sold J, we can say the following:
O = J + 6
As Oscar sold 6 cars more than Jackie.
Together, they sold 30 cars.
O + J = 30
Since we know that:
O = J + 6
... we can put this into our previous equation.
O + J = 30
(J + 6) + J = 30
J + J + 6 = 30
2 * J + 6 = 30
Subtract 6 from both sides:
2 * J = 24
Divide both sides by 2:
J = 24 / 2
J = 12
Jackie sold 12 cars.
Answer:
731 miles
Step-by-step explanation:
To solve this, we can set up a proportion.
Let's name the number of miles he travels in 17 hours x for now.
8/344=17/x
Simplify 8/344
2/86=17/x
Cross multiply
86*17=2*x
2x=1462
Divide both sides by 2.
x=731
He would travel 731 miles in 17 hours.
Answer:
(x+2)
Step-by-step explanation:
factor out the equation and get
(x+2)(6x-5)
The perimeter of the school crossing sign is 102 inches
length of each side = ?
in the question number of sides is not mentioned, so the answer may vary for the length of each side. if there is 5 sides divide 102 by 5, we get 20.4 answer so in case of 5 sides length of each side is 20.4 inches. if there is 4 sides divide 102 by 4 and we get 25.5 inches answer for the legnth each side.
Multiplication, hope I could help!
