Answer:
1. x = 24
2. r = -7
3. x = - 110
4. x = 10/3
Step-by-step explanation:
1. x/6 = 4 => x = 6 · 4 = 24
2. r/7 = -1 => r = -1 · 7 = -7
3. -x/11 = 10 => -x = 11 · 10 = 110 => -x = 110 / ·(-1)
Now we will multiply the both sides with (-1) and get
x = -110
4. x/4 = 5/6 It's the same as proportion x : 4 = 5 : 6
Now we will multiply external and internal members and get
6 x = 4 · 5 => 6 x = 20 => x = 20/6
Now we reduce the numerator and the fractional denominator with the number two and get
x = 10/3
God with you!!!
Answer:
$4.57. Hope this helps :)
Step-by-step explanation:
20+5=25
then you do
25-3.67= $21.33
you then divide that by the number of pounds she bought.
21.33/4= 5.3325
round that to the hundreths place and you get $5.33
so she paid $5.33 for a pound
Answer:
15 days
Step-by-step explanation:
Given that :
Time taken to clear 1/3 acre = 2 days
This means that, they will be able to clear ;
1/3 ÷ 2 = 1/3 * 2 /1 = 1/6 acre in one day
1/6 acres per day :
Hence, the number of days it will take to clear 2 1/2 acres will be :
2 1/2 acres ÷ 1/6
5 / 2 ÷ 1/ 6
5/2 * 6 /1 = (5*6) / (2*1) = 30/2 = 15
Hence, it will take 15 days to clear 2 1/2 acres

whenever we end up with an expression on the left-hand-side that is equal to the equation on the right-hand-side, is a way of saying, the system of equations, contains two lines that are exactly the same thing, but one is in disguise, something like say
9x + 15 = (3x + 5)3
now, if we distribute the 3 on the right-hand-side, we'd end up with the same equaton on the left-hand-side, so both are the same.
graphing wise, a solution is where both graphs intersect, when two equations are equal they'll intersect, well, at every single point, since their graph is really just one graph pancaked on top of the other, since they touch each other at every point, infinitely many solutions.
