What two numbers have a sum of 217 and a <br> difference of 85?

Setler [38]

Answer:

the two numbers are 151 and 66

Step-by-step explanation:

x+y =217

x-y = 85

add the two equations

x+y =217

x-y = 85

-------------

2x = 302

divide by 2

2x/2 = 302/2

x = 151

now find y

x+y =217

151+y =217

subtract 151 from each side

y = 217-151

y =66

Molly's town voted on a new speed limit. Out of 38 votes, 19 were in favor of the new speed limit. What percentage of the votes

RUDIKE [14]

Answer:

Percentage of votes in favour of new speed limit=50%

Step-by-step explanation:

There was a voting in Molly's town to set a new limit for the speed attained by a vehicle.

In Molly's town,

Number of votes recorded=38

Number of votes in favour of the new speed limit=19

We have to find the percentage of votes in favour of the new speed limit.

For that,the percentage of votes in favour= $\frac{votes in favour of new speed limit×100}{total votes}$

Percentage of votes in favour= $\frac{19*100}{38}$

Percentage of votes in favour=50%
