Answer:
2x + 6
Step-by-step explanation:
You multiply 2 by the numbers in parentheses. 2 times x is 2x, and 2 times 3 is 6.
Anwser: -23
Step-by-step explanation:
I knew that because i just did negative and positive numbers on a number line
The selling price is 2.5 times the cost. If the cost goes up by 0.25, the selling price needs to go up by 2.5*0.25 = 0.63 in order to maintain the gross margin.
Answer:
y=2x+4
Step-by-step explanation:
m=2 because it is perpendicular to (-1/2)
y-12=2(x-4)
y=2x+4
For this you need to know your angles in parallel lines.
3y will equal 87 as they are opposite angles and opposite angles are equal.
So y = 87/3
We can use the knowledge that angles in a straight line (in parallel line diagrams) will add up to 180. Therefore we do 180-87= 93. Now we know 3x=93 because just like the first example they are opposite angles. Now we know x=93/3.
(I didn’t have a calculator on me so you’ll have to work out the final result. Also I recommend looking into angles in parallel lines. I tried my best to explain so I hope you understand the jist of what I was trying to say.)
