Answer:
d
Step-by-step explanation:
keep change flip
keep 6/7
change division to multiplication
flip 18/3 to 3/18
Given:
GL = 4x + 1
LO = 6x - 3
GT = 17
TO = 21
To find:
The value of x.
Solution:
By the property of kite:
GL = GT and LO = TO
Take any one pair.
GL = GT
Subtract 1 from both sides.
Divide by 4 on both sides.
The value of x is 4.
Step-by-step explanation:
4+4=8..........Thats it
race entry costs 55, they use 15 of it to cover costs so they get 55-15 = 40 per entry
x = race entries
equation becomes 55000>= 40x +10000
45000>= 40x
x >= 45000/40 >= 1125
they need at least 1125 race entries to make $55,000
