You would do 1250 dived by 30.
1250/30 = 41.666
And if you round that, she would need 42 trays.
Hope I helped :)
I'm pretty sure it's d. y=-3x
Answer:
x=28
Step-by-step explanation:
180-42=138 since a triangle adds up to 180
2x+10+3x-12=138 then combine like terms
5x-2=138 add 2 to both sides
5x=140 divide each side by 5
x=28
