We can use ratios, in other words, if one part of the photo is changed x times, how many times does the other part change?
We can set up the proportion as :
width 1 : length 1 = width 2 : length 2
20 : 30 = 5 : x
We do inverse multiplication, or multiply the outer with outer and inner with inner (W1 * L2 and L1 * W2)
20*x = 30*5
20x = 150
Divide all by 10
2x = 15
Divide all by 2 to isolate x
x = 15/2
x = 7.5cm
Reciprocal means invert it . for eg- the reciprocal of 1/2 is 2/1 and of 4/7 is7/4.
Answer:
B
Step-by-step explanation:
If it cost $2.05 for each hamburger that's going to be your constant.
And it says plus an additional $2,000 so you will add that after 2.05x.
And it says 13,025 is the total so that would be on the left.
13,025 = 2.05x + 2,000
I'm 100% sure
I took Honors Algebra 1 in 8th grade, so you can trust me!!!
Answer:
start by going to the left three spaces over on the "X" axis (-3)
then go down seven spaces until both the "X" axis is over -3 and the -7 is on "Y" axis
(hope I helped)
