Answer:
12
Step-by-step explanation:
(B x H)/2 = Area
do the inverse of this with the answer to find the result
84x2 = 168
168/14 = 12
H = 12
The minimum number of games he could play is 11.
Answer:
810
Step-by-step explanation:
number of triangles needed = area of rectangle / area of triangle
area of triangle = 1/2 x base x height
1/2 x 6 x 8/3 = 8
area of rectangle = length x width = 90 x 72
90 x 72/ 8 = 810
X is the cost of the necklaces, y is the cost of the bracelets.
x + y = 1100
x = 1.2y
1.2y + y = 1100
2.2y = 1100
y = 500
x =600
