Paul, Colin and Brian are waiters. One night the restaurant earns tips totalling £77.40. They share the tips in the ratio 2:3:4.
anastassius [24]
The tip received by three of them - $77.40
They share in the ratio 2:3:4
The total number of units -2+3+4 = 9
9 units are for 77.40
Therefore 1 unit -77.4/9 = 8.6
Amount Brian receives - 4 units
Amount he gets - 8.6 x 4 = $34.4
Paul receives 2 units
His amount - 2x8.6 = $17.2
Brian receives 34.4 - 17.2 = $17.2 more than Paul

What is -x-3y=-3 and 2x+3y=5 using elimination method?
xxTIMURxx [149]

Answer:(2,1/3)


Step-by-step explanation:

-x-3y=-3

2x+3y=5


_________First solve for x since y is 0. -3y+3y=0

1X = 2

1x/1= 2/1

X= 2

Now substitute your x answer into any equation to find y I used second equation

2x+3y= 5

2(2)+3y=5

4+3y=5

3y=5-4

3y=1

3y/3=1/3

Y=1/3

What is the remainder when (3x4 + 2x3 − x2 + 2x − 19) ÷ (x + 2)?<br><br> 0<br> 5<br> 10<br> 15
Elanso [62]

Answer:  Second option is correct.

Explanation:

Since we have given that

f(x)=3x^4+2x^3-x^2+2x-19

And g(x)=x+2

To find the remainder, we use the Remainder Theorem, which states that when f(x) is divided by (x-c) then the f(c) is the required remainder.

So,

Here, we have,

x+2=0\\\\x=-2

So, we will find f(-2) which will give us the required remainder,

f(-2)=3(-2)^4+2(-2)^3-(-2)^2+2(-2)-19\\\\f(-2)=(3\times 16)-(2\times 8)- 4-4-19\\\\f(-2)=48-16-36-4-19\\\\f(-2)=5

Hence, Second option is correct.
