Answer:
The coordinates of the midpoint are;
(-6.5, -3)
Step-by-step explanation:
Here, we want to get the midpoint of the line segment
To get this, we use the midpoint formula;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
Thus;
(x,y) = (8 - 21)/2, (-10 + 4)/2
(x,y) = -13/2 , -6/2
(x,y) = (-6.5 , -3)
Answer:
$2000
Step-by-step explanation:
Simple Interest = $70
Rate = 3.5%
Time = 1
Principal = ?
Simple Interest = (Principal × Rate × Time)/100
Principal = (Simple Interest × 100)/(Rate × Time)
Principal = (70 × 100)/(3.5 × 1)
Principal = 7000/3.5
Principal = 14000/7
Principal = 2000
Answer:
64=4(a-44)
Step-by-step explanation:
64=4(a-44)
64=4a-176
64+176=4a
240=4a
4a=240
a=240/4
a=60 years old
2(4k+8)=10
8k+16=10 (she said 2k instead of 8k)
To continue solving, subtract 16 from both sides. That would give you 8k= -6. Then divide both sides by 8, and get -6/8 which equals -3/4.
Answer:
112.5
Step-by-step explanation:
you would then cross multiply. 90 x 100 and 80 x ?
you will then have 9000 = 80?
divide 9000 by 80 and you will get ? = 112.5
