Answer:
K+T=20
$9K + $6T = $168
K is the Kentucky blue grass in pounds
T is the Tall fescue in pounds
Step-by-step explanation:
You can start with the first equation. We don't know the exact amounts of each but we know that there was a total of 20 pounds, and there were 2 types of grass seeds, so we can get that the amount of pounds of Kentucky blue grass(K) and the pounds of Tal Fescue(T) has a sum of 20.
K + T = 20
For the second equation we know that there is a sum of $168 so we'll start with that. Then, we know he paid $9 per pound of K so $9* the value of K is the amount paid for Kentucky blue grass total. This can be represented as 9K. We do the same for T, 6T. Since the sum of the cost of $9T and $6K must be $168 we can write this as:
$9K + $6T = $168
Answer:
Step-by-step explanation:
The total of all 3 angles in every triangle equals 180 degrees. An isosceles triangle has two side lengths equal and two angle degrees equal.
So you either have two angles with each having 70 degrees and the third angle is 40 degrees,
70 + 70 + 40=180
OR
One angle of 70 degrees and two angles that are 55 degrees each.
70 + 55 +55 =180
I think it's not the same.
8 divided by 10 = 1.25
<span>25 divided by 30 is = 1.2</span>
I guess non of them, as all of them can be expressed by fractions.
