Alvin and Simon shared £540 in the ratio 4:5

Mathematics
1 answer:
Leto [7]3 years ago
8 0

Answer:

5/18

Step-by-step explanation:

540/9=60

60x4=240(Alvin's money)

60x5=300(simon's money)

Alvin gives half so you divide 240 by 2 which is 120

Simon gives a tenth so you divide 300 by ten which is 30

120+30=150

150/540=5/18 ( simpliest form)

SpyIntel [72]
If you would like to solve (x^2 + 5x - 36) / (x + 9), you can do this using the following steps:

a = ?
(x + 9) * (x + a) = <span>(x^2 + 5x - 36)
x^2 + ax + 9x + 9a = x^2 + 5x - 36
ax + 9x = 5x
a + 9 = 5
a = 5 - 9 
a = - 4

Ostrovityanka [42]

Answer:

The time taken by the driver is: t = 1.6 seconds

Step-by-step explanation:

Given

Distance covered by a race car = d = 300 mile

Speed of a car = s = 183.2 mph

To determine

The time of the driver = t = ?

Using the formula to determine the time of the driver

distance = speed x time

d = st

t = d/s

substitute d = 300 and s = 183.2

t = 300 / 183.2

t = 1.6 seconds

Therefore, the time taken by the driver is: t = 1.6 seconds
