x = 27

2. Complementary mean the angles equal 90 degrees when added, so

90  = 2x + 4x

x = 15

2x-4+50=100

2x-4=50

2x=54

x=27º

2x+4x=90

You earn $49 for washing 7 cars. How much do you earn for washing 4 cars?
ICE Princess25 [194]

Answer:

Step-by-step explanation:

We can use the rule of three!

We know we have the following relationship:

\frac{49}{7} = \frac{x}{4}

From here, we can solve this like any other equation:

4(\frac{49}{7}) = x\\x = 28

Therefore, you would earn $28 after washing 4 cars.

Good luck!

Can anyone help me please :( !
V125BC [204]

Answer:

D=3x+5, I=4x+8, -1x-3

Step-by-step explanation:

You don't know how many chocolates are in the boxes, so that's x. Always look at "and" and think + something. You know how many extra chocolates there are so you don't need to put the x. Remember, and=plus. Remember the equation is Mx+b.

The two expressions together is 3x+5=4x+8. Move the 4x to the other side with 3x+5 and make it negative. Same for eight. Hopefully that helps.

Savemore National bank starts the day with 2.81 times 10^4 dollars in the vault. At the end of the day, the bank has 3.5 times 1
suter [353]

ANSWER

There is

3.219\times  {10}^{5}

more money in the vault in the evening than in the morning.

EXPLANATION

The amount of money in the vault in the morning is

2.81 \times  {10}^{4}

The amount of money in the vault at the end of the day is:

3.5 \times  {10}^{5}

To find how much more money is in the vault at the end of the day than there was in the morning, we subtract to get:

3.5 \times  {10}^{5}  - 2.81 \times  {10}^{4}

= 3.5 \times 100000 - 2.81 \times 10000

350000 - 28100= 321900

Therefore, there is

3.219\times  {10}^{5}

more money in the vault.
