Answer:

8 people

(Let me know if there are any mistakes or anything I would add to the answer.)

Step-by-step explanation:

Based on the data Mia recorded, 6 out of 12 people had black hair, so if the next 16 people take their seats, 8 of them should have black hair. 6 out of 12 is half, and 8 is half of 16.

1. Solve the equations below.

Sergio039 [100]

Step-by-step explanation:

A) 3x + 8 = 23

3x = 23 - 8

3x = 15

x = 15 / 3 = 5

B) 5x + 1 = 3x + 17

5x - 3x = 17 - 1

2x = 16

x = 16 /2 = 8

C) 4 (x+2) = 32

4x + 8 = 32

4x = 32 - 8

4x = 24

x = 24 / 4 = 6

bongo had a balance of $345.28 in his checking account. During the week amounts: $65.08, $24.50, and $118.95. He then made a dep

vichka [17]

Answer: 192.75

Step-by-step explanation:

I am answering your question assuming that the three amounts were checks that were written out during the week.

Beginning balance = 345.28

Subtract the total amount of the checks (65.08 + 24.50 + 118.95 = 208.53)

345.28 - 208.53 = 136.75

Next, add the amount of the deposit. 136.75 + 56.00 = 192.75

Answer:

Mia can spend no more than $55 at the mall. She buys a jacket for $23. Necklaces are on sale for $8. Find the amount of necklaces Mia can buy. Write and solve an inequality.

First, make the equation. She can't waste no more than(≥ or =) $55. And she already used $23.

55= 23+8(n)

n= number of necklaces she can buy.

Now, subtract 23 to both sides.

55= 23+8(n)

-23 -23

32= 8(n)

Then, divide by 8 to both sides to find how many necklaces she can buy.

32= 8(n)

8 8

4=n So, she can buy 4 necklaces.

A bag of marbles contains 3 red, 5 blue and 2 yellow marbles. What is the probability of choosing a blue marble and then choosing a red marble without replacement. Simplify the fraction.

First, add up the whole amount of marbles.

3+5+2= 10

This is very simple, to find the probability, just put...

number of blue marbles

total number of marbles

This gives you, 5/10 and simplified into 1/2.

For the red marble, do the same thing.

number of red marbles

total number of marbles

This gives you, 3/10 and it can't be simplified.

A football team loses 5 2/3 yards on the first play. On the next play, they gain 2 3/4 yards. What is the overall increases or decreases in yards?

For this word problem, add 2 3/4 yards to 5 2/3 yards to find the overall decrease or increase in yards.

Solve the whole number parts..

5-2= 3

Solving the fractions part...

2 - 3 = 8 - 9 = - 1

3 4 12 12 12

3- 1/12= 2 11/12

So, it was a 2 11/12 decrease.

The graph of y = e^x is transformed as shown in the graph below. Which equation represents the transformed

Korolek [52]

y=e^x+3.

The given graph of the function y = e^x

he transformation occur when we add c to the parent function y = e^x giving us a vertical shift c unit in the same direction as the sign.

The y axis of a coordinate plane is the vertical axis. When a function shifts vertically, the value of y changes.

The given parent function: y = e^x,

we can now graph the vertical shift alongside i.e, c=3

Then, the upward shift function is, y = e^x + c

Substitute the value of c=3,

then, the transformed equation becomes, y = e^x + 3

as it goes through (0,4).

∴The equation y = e^x + 3 represents the transformed function.
