Step-by-step explanation:
Using ∆ law of vector addition,
PR→=PQ→+QR→PR→=PQ→+QR→ - (i)
Also,
RP→=RS→+SP→RP→=RS→+SP→ - (ii)
Taking LHS,
=PQ→+QR→+RS→+SP→=PQ→+QR→+RS→+SP→
[Put value of PR→=PQ→+QR→PR→=PQ→+QR→ from equation (i) ]
=(PR→)+RS→+SP→=(PR→)+RS→+SP→
[Put value of RP→=RS→+SP→RP→=RS→+SP→ from equation (ii) ]
=PR→+RP→=PR→+RP→
=PR→−PR→=PR→−PR→
=0=0
RHS
Answer:
-25,-6
Step-by-step explanation:
5 to - 10 is a 15 unit negative transition on the x axis
2 to -2 is a 4 unit negative transition on the y axis
We are being asked what would be the greatest value of x that would satisfy the expression 8.904x < 18.037. Let us try both 1 and 2, the solution is shown below:
For x=1, we have:
8.904 *1 < 18.037
8.904 < 18.037
For x=2, we have:
8.904*2 < 18.037
17.808 < 18.037
We could see the solution that the greatest possible value of x is 2.
He had walked 8 blocks, and that was 25% (or .25) of the distance to the school. Let’s let “D” represent the total distance...
D x .25 = 8 blocks
Divide both sides of the equation to solve for D...
D = 8 / .25 = 32
So the total number of blocks to his school is 32.
Answer:
D 26
Step-by-step explanation:
154+154=308
308-360=52
52 divided by 2
=26
