Answer:
b. x= -6 or x=2
Step-by-step explanation:
|2x+ 4| = 8
The absolute value equation has 2 solutions, one positive and one negative
2x+4 = 8 2x+4 = -8
Subtract 4 from each side
2x+4-4 = 8-4 2x+4-4 = -8-4
2x = 4 2x = -12
2x/2 =4/2 2x/2 = -12/2
x =2 x = -6
Answer:
B & C
Step-by-step explanation:
Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.
A-(5)(0.6)*7=21
B-(4/5)(15)+8=(0.8)(15)+8=20
C-4(8+2)/2=4(10)/2=40/2=20
D-14+4(2+3)=14+4(5)=14+20=34

Answer:
6750J
Step-by-step explanation:
30^2=900 900x15=13500 13500/2=6750
Distribute 4 with x and 2 to get the equation 3x+2=x+4x+8. Combine x and 4x to get 5x. Minus 3x from each side. Now you should have 2=2x+8. Subtract 8 from both side to get -6=2x. Divide and you get x=-3
Answer:
This problem gives us the total amount of cans and it also gives us the total cost and asks us to find the cost of each can when every can costs the same amount. To do this we need to $ to be on the top and the can on the bottom because we say price PER can.



Therefore, our final answer is that each can costs $2.78
