Your equation is 3(8-4)+2*5.5
you want to follow PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtaction
so first you will solve the parenthesis (8-4) = 4
put it into your exquation
3(4)+2*5.5
now the next thing we have is multiplication
3(4) = 12
2*5.5 = 11
now plug it into the equation
12+11=?
now you just do the addition
your answer should be
A. 23
Given:
The ratio of the cost of a shirt to the cost of a jacket is 2:5.
The jacket cost $240 more than the shirt.
To find:
The cost of the shirt and the cost of the jacket.
Solution:
Let x be the cost of the shirt.
The jacket cost $240 more than the shirt. So, the cost of Jacket is (x+240).
The ratio of the cost of a shirt to the cost of a jacket is 2:5. So,



Subtract 2x from both sides.


Divide both sides by 3.


So, the cost of shirt is $160.
Now, the cost of jacket is:

Therefore, the cost of shirt is $160 and the cost of jacket is $400.
( -3, 6 ) and ( 2, 6 )
Step-by-step explanation:
So your X axis is ( -3, 2).
And your Y axis is ( 6, 6 ).
So from -3 to 2, you going up +5, and from 6 to 6, you not moving anywhere, which means 0.
So the slope is 5/0
Cos(x) = 32/40 = 0.8 ⇒ x ≈ 37°
It would be 7.80 , just add 6.10 +1.7 hope this helps
