There are no solutions to 2x-5y=9 but if you are solving it by y=mx+b form than your answer would look like this: y=2/5x-9/5
6/14
Multiply both 3 and 7 by 2, this gives you equivalent fractions (there are more possible equivalent equations of course)
Answer:
D. 116
Step-by-step explanation:
Let the grasshoppers with a white marking be 2x.
Let the grasshoppers without a white marking be 3x.
2x + 3x = 290
5x = 290
x = 290 / 5
x = 58
The grasshoppers with a white marking
= 2x
= 2 ( 58 )
= 116
Answer:
1 sandal= $7
1 flip flop =$2.5
Step-by-step explanation:
say one sandal costs x and one flip flop costs y
3 x+y=23.50
4x+2y=33
solve using simultaneous equationsto find the values of x and y
