Answer: 270°, 630°, -450°, -810°
<u>Step-by-step explanation:</u>
positive: -90 + 360 = 270
270 + 360 = 630
negative: -90 - 360 = -450
-450 - 360 = -810

If you subtract another 2π, you will end up with a negative value. The question asks for the smallest positive value.
Answer:
2.6 : 400 -----convert both to either grams or kg, i'm doing grams
2600 : 400 ----simplify by 200
13:2 is lowest
Answer:
jim is correct, x <em>does</em> equal 7°. justify your answer by putting seven back into the equation. it gives you back that 180 equals 180, therefore it is correct
Step-by-step explanation:
so, all angles of a triangle have to add up to 180;
(15x) + (8x - 11) + (3x + 9) = 180
15x + 8x - 11 + 3x + 9 = 180
add your common numbers
26x - 2 = 180
add 2
26x = 182
divide 26
x = 7
put it back into the equation
15(7) + 8(7) - 11 + 3(7) + 9 = 180
180 = 180
The farmer has 17 hens.
<h3>What is a linear equation in two variables ?</h3>
An equation is linear if has highest degree of 1 and it has two variables.Generally they are in x and y.
For example -: 2x + 3y = 10
According to the given question a farmer has some hens and goats. He counts a total of 60 eyes and 86 feet between them.
Let us denote Hens by H and Goats by G.
We know both of them has 2 eyes each and we also know that a Hen has 2 legs and a Goat has 4 legs.
There fore the given data we can form two equations.
2H + 2G = 60 and 2H + 4G = 86.
Solving these two equations we have G = 13 and H = 17.
