Answer:

x=-6

Step-by-step explanation:

-13+22=-3(x+3)

Switch sides:

-3\left(x+3\right)=-13+22

Solve the right side:

-3\left(x+3\right)=9

Divide both sides by -3:

\frac{-3\left(x+3\right)}{-3}=\frac{9}{-3}

x+3=-3

Subtract 3 from both sides:

x+3-3=-3-3

x=-6

How many seconds after the egg is thrown will it be 10ft from the ground
PilotLPTM [1.2K]

Answer:

1.58

Step-by-step explanation:

Okay. We're solving for t because we need to know how many seconds. From the problem, we know the height (10), but we don't know when that height happens.

We can factor by multiplying -16 by 61 first to get -976 and see what multiplies to get -976 AND adds to get -7 at the same time. But we can also use the quadratic formula because, let's be honest, factoring can be a lot of extra work.

Plug both the plus and the minus versions into your calculator and...

There's no such thing as negative time, so -2.02 is automatically disqualified, leaving 1.58 as the answer.

Hope this helps, let me know if I missed anything!

A print company will print business cards for $.10 each plus a setup charge of $12. Another print company offers business cards
bonufazy [111]

Let the number of cards equal x.

Set up an equation for both companies, set equal to each other and solve for x.

0.10x + 12 = 0.12x + 10

Subtractb0.10x from both sides:

12 = 0.02x + 10

Subtract 10 from both sides:

2 = 0.02x

Divide both sides by 0.02:

X = 2/0.02

X = 100

100 cards would be the same price for both companies.

Tatiana [17]
Answers:
mode = 1
range = 5

-----------------------------------------

Explanation:

The mode is 1 because it is the most frequent value. It shows up four times compared to the other values (5,6) which only show up once and the value 4 only shows up twice.

The range is 5 because we subtract the max and min values to get 5.
In other words,
Range = Max - Min
Range = 6 - 1
Range = 5
