Let us say that:
x = weight of llamas
y = weight of okapi
From the problem, we can create the equations:
x + y = 450 -->
1
3 x = y + 190 -->
2
Rewriting equation 1:
x = 450 – y
From equation 2:
3 (450 – y) = y + 190
1350 – 3 y = y + 190
4 y = 1160
y = 290
From equation 1:
x = 450 – 290
x = 160
Therefore a llama weighs 160 kilograms while okapi weigh
290 kilograms on average.
Answer:
Step-by-step explanation:
A. Linear- the add up to 180
B. 3x-5+2x+3+4x+2=180
9x=180
x=20
C. plug x in
ABD- 55, DBK- 82, KBC- 43
Y = x^2 . . . (1)
y = -x + 2 . . . (2)
Putting (1) into (2) gives,
x^2 = -x + 2
x^2 + x - 2 = 0
x^2 - x + 2x - 2 = 0
x(x - 1) + 2(x - 1) = 0
(x + 2)(x - 1) = 0
x = -2 or x = 1
y = (-2)^2 or y = (1)^2
y = 4 or y = 1
Solution is (-2, 4) and (1, 1)
Answer:
The area of sector is 4.71 sq unites
Step-by-step explanation:
Step 1: Area of the sector = Area of the circle × (C/360) where C is the central angle.
Area of the sector = πr²(C/360) = 9π × 60/360
= 9 × 3.14 × 1/6
= 28.26/6 = 4.71 sq units

Since 240 milliliters are 0.240 liters, there are
servings in a 2-liter bottle. So, you can make 8 servings.
