Allison has 5 times as many baseballs cards as football cards.in all ,she 120 baseball and football cards.how many baseball card
Helen [10]

well to help you solve this problem you should set an equation as so...

B=5F

B+F=120

Next you would plug in what B equals into the equation B+F=120 like so

5F+F=120

then you add like terms

6F=120

then you isolate the variable by dividing like so

6F=120\frac{6F}{6} = \frac{120}{6}

F=20

so Allison has 20 football cards and you would subtract 20 from 120

120-20=100

so Allison has 100 baseball cards

If x is 5, then 6x =<br> 5x<br> 30x<br> 30
Wittaler [7]

Answer:

30

Step-by-step explanation:

If X is 5, then 6X is equal to 30. You can see to be able to get 30, you have to multiply 6 to X, which in this case is 5. So 6 times 5, you will now get the answer which is 30.

A ferry transports passengers to three different ports. from port a, the ferry travels east 3.5 miles to port b. the ship then t
lora16 [44]

The distance d from port c to port a from the given ship movement is gotten as; 7.7 miles.

<h3>How to calculate bearing distance? </h3>

We are given;

Ferry travels east 3.5 miles from Port b.

Then it turns 75° south and travels for 6 miles till it gets to Port c

To get the distance d from port c to port a, we would make use of cosine rule which is;

c = √(a² + b² - 2ab*cos C)

Thus;

d = √(3.5² + 6² - 2(3.5 * 6)*cos 75))

d = 7.7 miles
