Solve :<br><br> y=3.58•x+ 202.6<br> &<br> y=2.3•x+160.7

Ierofanga [76]

Answer:

$x=-32.73\,,\,y=85.43$

Step-by-step explanation:

Given: $y=3.58x+202.6\,,\,y=2.3x+160.7$

To find: value of x and y

Solution:

$y=3.58x+202.6\,\,(i)\\y=2.3x+160.7\,\,(ii)$

From equation (i) and (ii),

$3.58x+202.6=2.3x+160.7\\3.58x-2.3x=160.7-202.6\\1.28x=-41.9\\x=\frac{-41.9}{1.28}=-32.73$

Put $x=-32.73$ in (i)

$y=3.58(-32.73)+202.6\\=-117.17+202.6\\=85.43$

lara31 [8.8K]

X=number of gallons that she must order.

4 gallons-----------------3 weeks
(7 gallons + x)--------12 weeks

We solve this rule of 3.
(7 gallons +x)3 weeks=4 gallons*12 weeks
21 gallons weeks+3 x weeks=48 gallons weeks
3x weeks=48 gallons weeks - 21 gallons weeks
3x weeks=27 gallons weeks
x=(27 gallons weeks) / 3 weeks=9 gallons.

Solution: she must order 9 gallons more.
