Hi there. :)
I'll try to make this simpler for you.
Let's focus on the equation from left to right, to avoid clutter.
-4(3 * 1/2) = -4(1.5)
Now to the right.
+ 2(3) = + 6
Now combine!
-4(1.5) + 6 =
-6 + 6 = 0
The answer is 0.
Lets write down the information that we know.
Jessie has 7 stacks of 6 dimes, so Jessie has a total of 6*7 dimes
Dimes=7*6=42dimes
Jessie has 42 dimes, but then she found another one so lets add one more dime.
42+1=43 dimes
Jessie has 8 stacks of 5 nickels, so Jessie has 8*5 nickels
Nickels=8*5=40nickels
Jessie has 40 nickels, but then she found another one so lets add 1 to the total number of nickels.
40+1=41nickels
Now we can answer the question.
How many dimes and nickels does jessie have in all?
nickels+dimes=
41+43=84 coins
Jessie has 84 coins in total
Answer:
8 x = 60.10251159
9 x = 3.66062978
Step-by-step explanation:
Hey There!
So to answer these questions we need to use the Law of sines
Consider the following image
So to find x in number 8 we setup an equation

now we solve for x
step 1 multiply each side by sin 90
now we have

if you plug the equation in a calculator you get that
x=60.10251159
<u>( make sure if it says to round to the nearest.... that you round before entering your answer)</u>
For number 9 the equation would be

now we solve for x
step 1 multiply each side by sin 24
now we have

if you plug this into a calculator you get that
x = 3.66062978
<u>(once again if it says to round to the nearest... make sure you round before you put in your answer.)</u>
Y=-3x+23
distribute -3, get y alone (add 2 to both sides)
