Answer:
Paul gets £2(9.8) = £19.6, and
Colin gets £1(9.8) = £9.8, and
Brian gets £5(9.8) = £49
Step-by-step explanation:
Find the multiplier x in 2x + 1x + 5x = £78.40.
Summing up the left side: 8x = 78.40
Dividing both sides by 8 to isolate x:
x = 9.8
Then Paul gets £2(9.8) = £19.6, and
Colin gets £1(9.8) = £9.8, and
Brian gets £5(9.8) = £49
As a check, add these together; the sum must be £78.40:
£19.6 + £9.8 + £49 = £78.40. So our figures are correct.
Brian gets £49 and Colin gets £9.8. Subtracting, we obtain:
£39.20. This is the amount by which Brian's tips exceeds Colin's.
Answer:
< according to me
Step-by-step explanation:
I think K=1.123
you have to find by how much it's increasing, think of 6(1/2) times WHAT equals 7(1/3)
6(1/2)a=7(1/3)
a=1.123
That means each side will be the same times 1.123
x=4.492
you can round that to 4.49 or 4.5 or 5
Answer:
X= 65
Step-by-step explanation:
180°-50°=130 (Angles on a straight line)
2x=130 ( Corrresponding Angle)
X= 130÷ 2
= 65
Hope this helps.
Y-(-1)=3(x-3)->y+1=3x-9->y=3x-10 so y=3x-10 is your new line
