Answer: A. Distribute the 3 outside of the parathesis to everything inside the parenthesis

We use the order of operations, also known as PEMDAS.

Since there is a variable inside the parenthesis, we cannot add/subtract 4. This means the next step is to distribute.

After distributing, the equation looks like this and we can solve it from there:

4x + 12 = 30

A student is saving money to buy a video game. The student currently has $20 and plans to save $10 every month. Write a function

4vir4ik [10]

Answer:

y = amount saved in dollars

x = months

Since the student already has $20 dollars saved (20) and plans to save $10 per month (10x), the equation so far is y = 20 + 10x.

You can use this to solve questions based of the equation/situation by filling in any numbers you are given where the variables are.

Hope this helps! :)

michael rented a truck for one day. there was a base fee of $20.95 , and there was an additional charge of 93 cents for each mil

jonny [76]

Let x = number of miles, cost per mile = 93 cents = $0.93

Cost = 20.95 + 0.93*x

200.44 = 20.95 + 0.93x

0.93x + 20.95 = 200.44

0.93x = 200.44 - 20.95

0.93x = 179.49

x = 179.49/0.93

x = 193

He drove 193 miles.

Solve the system using the substitution method <br> 4x+6y=8<br> 3x+y=9

inessss [21]

4x+6y=8
3x+y=9

y = 9 - 3x

4x + 6(9-3x) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7

y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7

Help on this one please??

xenn [34]

Answer:

C = ~50 deg

Step-by-step explanation:

Apply the cosine theorem:

cos(C) = (CA^2 + CB^2 - AB^2)/(2*CA*CB)

= (7.5^2 + 6.5^2 - 6^2)/(2*7.5*6.5)

= 0.6410

=> C = ~50 deg

Hope this helps!
