Substitution method <br><br> x-7y=-9<br> -x+8y=10

max2010maxim [7]

Answer:

x = -2, y=1

Step-by-step explanation:

x-7y=-9---------------------equation 1

-x+8y=10-------------------equation 2

From equation 1, make x the subject of formula

x=7y-9----------------------equation 3

substituting x=7y-9 in equation 2,

-(7y-9)+8y=10

Expanding bracket

-7y+9+8y=10

Collecting like terms

8y-7y=10-9

y=1

substituting y=1 in 3

x=7(1)-9

x=7-9

x=-2

Suppose your car gets 28 miles per gallon of gasoline, and you are driving at 55 miles per hour. Using unit analysis, find the a

pentagon [3]

<h3>Answer:</h3>

1 27/28 ≈ 1.964 gallons/hour

<h3>Step-by-step explanation:</h3>

You want gallons in the numerator of your unit rate, but that unit is in the denominator of the mileage rate. So, the computation must involve division by 28 mpg. Hours is already in the denominator of 55 mph, so the computation will involve multiplication by that rate.

... (55 mi/h)/(28 mi/gal) = (55 mi/h)·(1 gal/(28 mi)) = 55/28 gal/h

... = 1 27/28 gal/h

Of the 1450 books in the library, there are 6 times as many books in the fiction section as are in the nonfiction section. Also,

guajiro [1.7K]

Number of books in non fiction section = 200

Number of books in fiction section = 800

Number of books in reference section = 850

Step-by-step explanation:

Total number of books in the library = 1850

Let us assume, number of books in non fiction section = m

Number of books in fiction section= 4 x Number of books in non fiction

= 4 x (m)

So, the number of books in reference section = 650 + m

Now, Total Number of books = Number of { Fiction + Non- Fiction + Reference} Books

or, 1850 = m + (4 m) + 650 + m

or, 6 m + 650 = 1850

⇒ 6 m = 1850 - 650 = 1200

or, m = 1200 / 6 = 200

⇒ m = 200

Hence, the number of books in non fiction section = 200

Number of books in fiction section = 4 m = 4 x 200 = 800

Number of books in reference section = 650 + m = 200 + 650 = 850
