Hello from MrBillDoesMath!

Answer:

x = 4, y = 5

Discussion:

-2x + 5y = 17          (*)

x     +  y  = 9            (**)

Multiplying (**) by 2 gives

2x + 2y = 18            (***)

Adding (*) and (***) gives

(-2x + 5y) + (2x + 2y) = 17 + 18              =>

(-2x + 2x) + (5y + 2y)  =35                    => as -2x + 2x = 0 and 5y +2y = 7y

0 + 7y = 35                                           => divide both sides by 7

y = 35/7 = 5

Substituting y = 5 in (**) gives x + y = 9 or x + 5 = 9 => x = 9-5 = 4

Thank you,

MrB

erik drove 439.92 miles on 15.6 gallons of gas. To the nearest hundredth, how many miles could he drive on 39.7 gallons of gas?
Thepotemich [5.8K]
In the question it is already given that Eric drove for 439.92 miles on 15.6 gallons. It is required to find the distance traveled on 39.7 gallons of gas. Also we have to find the answer to the nearest hundredth.
Then,
In 15.6 gallons Eric can drive for a distance = 439.92 miles
In 39.7 gallons Eric can drive for a distance = [(439.92/15.6) * 39.7] miles
                                                                       = 1119.54 miles
So the total distance traveled by Eric is 1120 miles with 39.7 gallons of gas. The answer has been calculated to the nearest hundredth.

Frequently on tour, a band called the Chieftains
JulijaS [17]

<u>revered internationally</u><u> as spirited performers of </u><u>traditional Irish music</u><u>.</u>

<u />

<h3>What are Chieftains?</h3>

The Chieftains are a traditional Irish folk band formed in Dublin in 1962, by Paddy Moloney, Sean Potts and Michael Tubridy. Their sound, which is almost entirely instrumental and largely built around uilleann pipes, has become synonymous with traditional Irish music and they are regarded as having helped popularise Irish music around the world.

They have won six Grammys during their career and they were given a Lifetime Achievement Award at the prestigious BBC Radio 2 Folk Awards in 2002. Some music experts have credited The Chieftains with bringing traditional Irish music to a worldwide audience, so much so that the Irish government awarded them the honorary title of 'Ireland's Musical Ambassadors' in 1989.
