Answer:
85 square ft
Step-by-step explanation:
8.5cm times 4 cm = 34 cm
34 cm times 2.5 (because 1 cm = 2.5ft) = 85 square ft
The divisor is 4.033 because it divides 198,200. Rounded to the nearest whole number, it is 4 because 0 is less than 5, so the next highest (whole) place is unchanged.

Answer:
Q(0, 1 )
Step-by-step explanation:
To find where the curve crosses the y- axis let x = 0 in the equation and evaluate for y, that is
x = 0 → y = = 1 , thus
Q(0, 1 )
Answer:
x = -2
x = -9
Step-by-step explanation:
The linear system is:
8x - 4y = 20 ⇒ (1)
5x - 8y = 62 ⇒ (2)
To solve the system multiply equation (1) by -2 to make the coefficients of y equal in values and different in signs, then add the resulting equation with equation (2)
∵ -2(8x) + -2(-4y) = -2(20)
∴ -16x + 8y = -40 ⇒ (3)
- Add equation (2) and (3)
∴ -11x = 22
- Divide both sides by -11
∴ x = -2
Substitute the value of x in equation (1) or (2)
∵ 8(-2) - 4y = 20
∴ -16 - 4y = 20
- Add 16 to both sides
∴ - 4y = 36
- Divide both sides by -4
∴ y = -9
