To find how much it was per pound, you divide $8.10 by 2.5 lbs
8.10/2.5 = 3.24
$3.24 per pound
Answer:
C, 1 : 16
Step-by-step explanation:
Small Circle
The radius is half of the diameter. 3 inches.
π×r²=A
We'll use 3.14 for pi.
3.14×9
28.26 in²
Bigger Circle
6×4= 24
So the diameter is 24. The radius is 12.
3.14×12²
3.14×144
452.16 in²
Let's divide.
452.16÷ 28.26
= 16
Therefore, the answer is C, 1 : 16.

Answer:
<u>The solution of this system of equation is ( 3, - 8)</u>
Step-by-step explanation:
1. Let's solve the system of equations:
First equation:
x + 2y = - 13
x = - 13 - 2y
Second equation:
12x + 5y = -4
12 * (- 13 - 2y) + 5y = - 4 (Replacing x with - 13 - 2y)
-156 -24y + 5y = - 4
-24y + 5y = - 4 + 156 (Like terms)
-19y = 152
y = - 152/19
<u>y = -8</u> (Dividing by 19)
Solving x
x + 2y = -13
x + 2 (- 8 ) = - 13
x - 16 = - 13
x = - 13 + 16
<u>x = 3</u>
2. Proving that x = 3 and y = - 8 are correct:
12x + 5y = -4
12 * 3 + 5 * -8 = -4
36 - 40 = - 4
- 4 = - 4
<u>We proved that x = 3 and y = - 8 are correct</u>
Answer:b
Step-by-step explanation:y=2x-3
Answer:
m<1=61
m<2=40
m<3=60
m<4=80
m<5=100
Step-by-step explanation:
180/3=60
180/9=20
20x2=40
20x4=80
20x3=60
59+60=119
180-119=61
180-80=100
