The facts to apply is PEMDAS which is parenthesis,exponents, multiplication,division,addition and subtraction.
Then group like terms if there are any.
You finally get to a simplified answer if there are no like terms
Answer:
x=1, y=2. (1, 2).
Step-by-step explanation:
-3x+10y=17
3x+7y=17
---------------
17y=34
y=34/17
y=2
3x+7(2)=17
3x+14=17
3x=17-14
3x=3
x=3/3
x=1
Answer:
-42
Step-by-step explanation:
-2y = 46
y = 46/ -2
y = -23
Substitute y in y = 4x-11
-23 = 4x -11
-23+11 =4x
-12 = 4x
x = -12/4
x = -3
Now plug in x value in 14x
14(-3) = -42
Answer:
Question 13. I believe is C.
Step-by-step explanation:
take your area of the face you are given aka your 7 5/6 and multiply it by six since there are six faces.
You can convert the mixed number to an improper fraction
= denominator times the whole number ( 6x7)= then add the numerator (42+5)=
Then multiply by six to get your answer
