Among other approaches, finding the actual equation of the line thru these points is workable:
<span>6 12
10 20
20-12
slope m = ---------- = 8/4 = 2 The only answer choice that matches is A:
10-6 y = 2x</span>
x=ferns ; y=ivy
12x+8y=260
6x+15y=240
x=60 -(15/6)y
12(60+ (15/6)y + 8y = 260
x=60 -(15/6)y
720 - 30y + 8y = 260
x=60- (15/6)y
-30y +8y= 260-720 ==> -22y= -460
x=60 -(15/6)y
y= (-460)/(-22)= 20.9090909091
y=20.90
x=60 -(15/6)×20.90= 7.75
×(ferns)=7.75$
y(ivy)=20.90$
Answer:
$1,139
Step-by-step explanation:
1,340 × .15 = 201
1,340 - 201 = 1139
Answer: 1139
Answer:
You will pay $4.31
Step-by-step explanation:
I know this because a fourth of $5.75 is 1.4375 so you would round it to $1.44 and then $5.75 - $1.44 is $4.31.
So you will pay $4.31 for one milkshake.
