Know this? Add apples to apples and oranges to oranges.
This problem becomes much easier if the fractions are converted to decimal fractions for comparison purposes:
<span>2⁄3 , 7⁄6 , 1⁄8 , 9⁄10
are approx equal to 0.67, 1.17, 0.125, 0.90
So, rearranging these numbers in increasing order, we get
0.125, 0.67, 0.90, 1.17.
We could go back to the originals: 1/8, 2/3, 9/10, 7/6.</span>
You do 3x6 first to get 18.
You get 3-18+2.
Then you do 3-18 which is -15.
You get -15+2.
Then you do -15+2 which is -13.
It equals -13.
Answer:
(1/2,4)
Step-by-step explanation:
First, determine y in first equation: 2x+y=5 or y=5-2x
replace value of y determined in first equation (5-2x) into 2nd equation
4x-3(5-2x)=-10
4x-15+6x=10
10x=5
x=1/2
put value of x into either equation to solve for y so
2(1/2)+y=5
1+y=5
y=4
answer: x=1/2, y=4
check answer by substituting x and y into either equation:
4x-3y=-10
4(1/2)-3(4)=-10
2-12=-10
-10=-10
or
2x+y=5
2(1/2)+4=5
1+4=5
5=5
$10.83 because you need to divide 6.50 by .6 to get that answer approximately.
<span>(2*h)/15 = 20 // - 20
(2*h)/15-20 = 0
2/15*h-20 = 0 // + 20
2/15*h = 20 // : 2/15
h = 20/2/15
h = 150
h = 150</span>
