Assuming that the units of speed are also in minutes, for instance km/min or m/minute. Then you would not need to convert time into another unit. As for multiplying the bases of 10, remember that 10 = 10^1. So it would be 10^8+1 = 10^9. So the result would be 24 • 10^9 but in proper scientific notation it would be 2.4 • 10^10.
Yet, I believe you are working with the speed of light and thus you would need to convert 8 minutes into seconds which would be 8 • 60 = 480 seconds. Then do the following operation:
480 = 4.80 X 10^2
(4.80 X 10^2 seconds)(3.00 X 10^8 metres/second)
Simply multiply the whole numbers, and the bases of 10, and put in proper scientific notation.
Answer:350
Step-by-step explanation:you multiply the amount of points which is 70 times the amount of targets which is 5 so it’s 70x5=350
Answer:
6x-15
Step-by-step explanation:
3*2x= 6x
3*5=15
6x-15
(a) 2x+4(x-1)=2
2x+4x-4=2---- Distrubution of 4(x-1)
6x-4=2---- Combining like terms
6x=6---- Making -4 equal 0 by adding +4 to both sides
x=1---- Divide the coefficiant (6)
(b) 25-x=15-(3x+10)
25-x=15-3x-10----Distribute the -1
25-x=5-3x---- Combine like terms
25=5-2x---- Make -x equal 0 by adding +x to both sides
20=-2x---- Make 5 equal zero by subtracting 5 (or adding -5) to both sides
-10=x---- Divide by the coefficiant (-2)
(c) 4x= 2x+2x+5(x-x)
4x=2x+2x+5(0)---- Distribute. Alright this might look hard but realy it is 1x-1x so the answer is 0
4x=2x+2x---- 5 times 0 is 0
4x=4x---- Combine like terms
x=x ---- divide by the coefficiant
