Answer:
< 15, - 21 >
Step-by-step explanation:
Multiply each of the components of the vectors by the scalar quantity, then add corresponding components of each vector.
9u + 2v
= 9 < 3, - 1 > + 2 < - 6, - 6 >
= < 27, - 9 > + < - 12, - 12 >
= < 27 - 12, - 9 - 12 >
= < 15, - 21 >
Answer:
£34.45
Step-by-step explanation:
Paul,colin and brian are waiters. One night the restaurant earns tips totalling £77.50.They share the tips in the ratio 1:3:5.
The sum of their Proportion is
1 + 3 + 5 = 9
For Brain
5/9 × £77.50 = £43.06
For Paul
1/9 × £77.50 = £8.61
Hence:
How much more does brian get over Paul?
This is calculated as:
£43.06 - £8.61
= £34.45
Answer:x=-2.30
Step-by-step explanation:
6.95x+16.2-2.36x=3.2x+13
6.95x-2.36x+16.2=3.2x+13
4.59x+16.2=3.2x+13
4.59x-3.2x+16.2=13
1.39x+16.2=13
1.39x+16.2-16.2=13-16.2
1.39x=-3.2
1.39x÷1.39=-3.2÷1.39
X=-2.30
Loss implies a negative change, so the integer will be -15.
