Money donated by 18 Students = 18*5.25 = $94.50
Answer:
(–1,4)
Step-by-step explanation:
x – y = –5
3x + y = 1
You omit Ys due to their positive and negative signs and you got
4x = –4===> x= –1
and now place –1 inside the upper linear equation and there you have the Y, look
–1 – Y= –5===> –Y= –4===> Y = 4
(–1,4)
Answer:
30%
Step-by-step explanation:
Total number of cars sold = 4000
1200 were Mazdas.
% Mazdas = 1200/4000 * 100 = 0.3 * 100 = 30%
Answer:
3360
Step-by-step explanation:
simple interest=principle*rate*time/100
simple interest=20000*5.6*3/100
simple interest= 200*5.6*3
simple interest = 3360
Answer:
3 miles
Step-by-step explanation:
Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles
This is the change in miles / change in time.
Chang in miles = 3
Change in time = 1
Slope = 3/1
Slope = 3
