yo might be tricked to do 2(-7) but that's multiplcation
so expoments
(-6)^2=36
now we have
36/12-2(-7)
mulitipictioan or division whicever comes first
division
36/12=3
multiplcation 2(-7)=-14
now we have
3-(-14)
3+14
17
answer is 17
Answer:
x = 11
Step-by-step explanation:
Given the expression;
5x+2y=67 ...1
x=3y−7 ....2
Substitute 2 into 1
5(3y-7)+2y = 67
15y - 35 + 2y = 67
17y = 67+35
17y = 102
y = 102/17
y =6
Recall that x = 3y - 7
x = 3(6) - 7
x = 18 - 7
x = 11
Hence the value of x is 11
Answer:
D
Step-by-step explanation:
check the picture below.
make sure your calculator is in Degree mode.
For the mean you add them all up and divide by the ammount of numbers you added. So it would be 118
