Answer:
2000
Step-by-step explanation:
1600 is 100% - 20% = 80% of the original price.
So it is 4/5 of the original price.
So, the marked price is 1600 * 5/4 = 2000
Answer:
JK = 20
Step-by-step explanation:
Angle Bisector Theorem: an angle bisector of a triangle divide the opposite side into two segments that are proportional to the other two sides of the triangle
LK / JK = LM / JM
(45 - JK) / JK = 75 / 60 = 5 / 4
5 JK = 4 (45 - JK)
5 JK = 180 - 4 JK
9 JK = 180
JK = 20
Answer:
Step-by-step explanation:
I didn’t get that right answer
Let the number of corn acres be xx and the number of wheat acres be yy.
We are given that:
1- The total number of acres is 180, this means that:
xx + yy = 180 ..............> equation I
2- The number of corn acres is 3 times that of wheat. This means that:
xx = 3yy .........> equation II
Substitute with equation II in equation I to get the value of yy as follows:
xx + yy = 180
3yy + yy = 180
4yy = 180
yy = 45 acres
Now substitute with yy in equation II to get xx as follows:
xx = 3yy
xx = 3*45
xx = 135 acres
Based on the above calculations:
acres of corn = xx = 135 acres
acres of wheat = yy = 45 acres
