Answer:
5. (x, y) = (19.3, 46)
6. (x, y) = (6, 7)
Step-by-step explanation:
In similar triangles, all corresponding measures have the same proportion. In figures like these, the corresponding measures are on the same line of the X. Here, we've written the ratios as (short measure)/(long measure).
___
5. 30/60 = x/38.6 = 23/y
x = 38.6·30/60 = 19.3 . . . . . multiply by 38.6
y = 2·23 = 46 . . . . . multiply by 2y
___
6. 4/6 = x/9 = y/10.5
x = 9·4/6 = 6 . . . . . . multiply by 9
y = 10.5·4/6 = 7 . . . .multiply by 10.5
Given:
Total amount of new laptop = $335
Down payment = $50
Number of equal monthly payments = 6
Amount of monthly payments =
To find:
The equation that represents the given situation.
Solution:
We have,
Amount of monthly payments =
Total amount for 6 equal monthly payments =
We know that,
Total amount = Down payment + Total amount of all monthly payments
Therefore, the required equation for the given situation is .
He is left with 12
1/5 of 10 is 2 so he was left with 8
2*2 is 4, and 8+4 is 12!
Answer: -4 / 8 - 12 / 4 = -16 / 12
Step-by-step explanation:
-4g = (-12 / 4)
2f = (-4 / 8)
Just sum them...
