Answer:

5b+1c=3b+5c

Step-by-step explanation:

Let's use the variable c for the circles and b for the boxes.

The weights are the same on both sides, so count the boxes and circles on each side.

There are 5 boxes and 1 circle on the left side. The left side of the equation says 5b+1c.

There are 3 boxes and 5 circles on the right side. The right side of the equation says 3b+5c.

And since the 2 sides are equal, you split the 2 sides of the equation with =.

5b+1c=3b+5c

3a+11=7a-13 with shown work​
DaniilM [7]

3a+11=7a-13

move 7a to the other side

sign changes from +7a to -7a

3a-7a+11= 7a-7a-13( combine like terms)

3a-7a+11= -13

-4a+11= -13

move 11 to the other side

sign changes from +11 to -11

-4a+11-11= -13-11

-4a= -13-11

-4a= -24

divide both sides by -4 to get a by itself

-4a/-4= -24/-4

Answer: a= 6

In a probability experiment, Karen flipped a coin 84 times. The coin landed on heads 36 times. What percentage of the coin flips
hodyreva [135]

Answer:

57.1%

Step-by-step explanation:

We know that a coin has only two sides, heads or tails. Therefore if of the 84 times, 36 times he fell in heads, the other times he fell in tails.

84 - 36 = 48 times fell in tails.

Therefore to calculate the percentage that fell in tails, it would be the ratio between the number of times it fell in tails and the total number of experiments:

48/84 = 0.571, and that is 57.1%

Which means that 57.1% of the times the coin was thrown fell into tails.
