You have to use PEMDAS, by multiplying before you add. So when you multiply 5*6, you get 30 and add the remaining 27 to get 57.
Answer:
30.80
Step-by-step explanation:
$370/12ft^2
If the solution exists, y=y....
3x+2=-x/4+1 make everything have a common denominator of 4...
(12x+8)/4=(-x+4)/4 now multiply both sides by 4
12x+8=4-x add x to both sides
13x+8=4 subtract 8 from both sides
13x=-4 divide both sides by 13
x=-4/13
x≈-0.31 and the only pair in your choices having an x value close to that is:
(-0.3, 1.1)
To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5
then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5
1) B irrational
2) B sometimes because a negative integer is not a whole number
3) C irrationals
4) C and D are whole numbers
5) C irrational
6) D 7/10 because a rational number is always a faction
7) C rational numbers
8) D real and rational
9) D rational, real, whole number
10) A integers
