Answer:
670
Step-by-step explanation:
(3*1+2)+(3*2+2)+........(3*20+2)=670
Ratio walkers to riders 2:7
7/2=3.5
The bus riders are 3.5 times more than the riders
<span>2,783 and 7,283
The value of 2 in 2783 is ten times the value of 2 in 7283
</span>
In 2,783 "2" is in the thousands place. It basically represents 2,000.
In 7,283 "2" is in the hundreds place. It represents 200.
Answer:
No, it's not equivalent
Step-by-step explanation:
Try and solve the one with the bracket first. Expand 8(15-r) : 8x15 and 8x-r = 120 - 8r
Therefore, the equation can now be written as:
6r-r + 120-8r + 23-6
Rearrange the like terms together and solve the equation:
6r-r-8r + 120+23-6 = -3r + 137
The answer for this solution is D
-3 and b
