I’m not sure what the gate has to do with the problem, but you should just divide 780 by 120 to get 6.5. In other words, each foot costs $6.50.

If y is directly proportional to x and when y = 35, x = 140, what is the value of x when y = 70?
levacccp [35]

Answer: 280 = x


Step-by-step explanation: Okay you are using this equation! y = kx But you must rearrange it!

When rearranged you get y/x = k

Plug in x and y!

y/x = k

35/140 = k

0.25 = k

Now find the value of x.

You use this formula now, y/k = x

Plug in k from the last problem and y = 70

y/k = x

70/0.25 = x

280 = x

Can you please help me I need help
DaniilM [7]
I think its C. 7x3 = 21. 7x18 = 126. 9x7 = 63
If you all that the answer its 210. If you estimate what that little part above the farthest to the right shape, I'd say its near 18 to 21. Then add 210 with either numbers 18 through 21, it would be close to 227 square meters.

Write in point-slope form (-4,-3) m=-1
zvonat [6]

Point-slope form: y + 3= -1(x + 4)

Slope-intercept form: y = -1x - 7

y = m * x + b,

where:

m is the slope; and

b is the intercept of the y-axis.
