She needs 10 one fourth cups because 1=4/4. So 2=8/4 and 2/4+8/4=10 which means that she needs to use her cup 10 times.
Answer:
Start
Step-by-step explanation:
The measure of spread is the variation so we can use range:
Range of Start:
15 - 7 = 8
Range of End:
13 - 6 = 7
Start had a bigger value so it had the greater variation

5. read the measurments
6. Ben got his answer
1) -3x-4y=10 ==> - 3x = 10+4y ===> 3x= -10-4y==> x=(-10-4y)/3
Now replace x by its value in 2)
2) -6x+y=-16 ==> - 6[( - 10- 4y)/3] + y = -16 ==> -2[(-10-4y] +y =- 16
+20+8y+y =- 16==> 9y = - 16 - 20 ==> 9y = -36 & y = - 4.
Now replace y by (- 4) in any of the 2 equations & you will find x = 2
