Step-by-step explanation:
Hi, I think correct variant is B
(28÷7)+7=4+7=11
Answer: the answer is x=72
Step-by-step explanation:
Step 1: simplify both sides we know 15=x/4 -3 (the x holds a invisible 1)
the equation should look something Like: 15=1/4x-3 then FLIP the equation such as:
1/4x-3=15 then add 3 on both sides so 15+3=18
step 2: our equation is now 1/4x=18 (we see 4 is being divided the opposite of division is multiply) therefor multiply the 18 with 4
18*4=72 which means x=72
Answer:
this question is not complete. need another equation
Step-by-step explanation:
give another equation then I can solve

Answer:
(4,-4)
Step-by-step explanation:
Just plot it or like I did it like this
Since moving right or left is X axis, just add 5 to -1 becuase its ont he X axis
Then for the bottom and up, thats Y so subtract that to the Y axis so 2-6=-4
4,-4
Answer: (3, -2)
Step-by-step explanation:
The vertex is the highest or lowest point of a parabola, and I found it. Hope this helps :)
