$147

divide $84 by 4 and you get 21
divide $105 by 5 and you get 21 

so, multiply 21 with 7 and you get $147

the amount of gasoline used by a car varies jointly as the distance travelled and the square root of the speed.Suppose a car use
klemol [59]

Answer:

200 litres

Step-by-step explanation:

let g be gasoline used, d the distance travelled and s the speed, then the equation relating the quantities is

g = kd\sqrt{s} ← k is the constant of variation

To find k use g = 25, d = 100 and s = 100, then

25 = k × 100 × \sqrt{100} = k × 100 × 10 = 1000k ( divide both sides by 1000 )

0.025 = k

g = 0.025d\sqrt{s} ← equation of variation

When d = 1000 and s = 64, then

g = 0.025 × 1000 × \sqrt{64} = 0.025 × 1000 × 8 = 200

Simultaneous equation refer to a pair of equations that are solved at the same time.

<h3>What is a simultaneous equation?</h3>

A  simultaneous equation refer to a pair of equations that are solved at the same time.

For problem 1;

x = 4 - y ------ (1)

y^2 = 3x + 19 ----- (2)

Substitute (1) into (2)

y^2 = 3(4 - y) + 19

y^2 = 12 - 3y + 19

y^2 +3y - 31 =0

y = 4.27 or -7.27

x = 4 - 4.27 = 0.27

or

x = 4 - (-7.27) = 11.27

For the second problem;

x = 7 - y

y^2 = 5x - 15

Substitute (1) into (2)

y^2 = 5(7 - y) - 15

y^2 =35 -5y -15

y^2 + 5y - 20 = 0

y =2.62 or -7.62

x = 7 - 2.62 = 4.38

OR

x=  7 - (-7.62) = 14.62
