Here x increases (as we move to the right), and y increases with it. The slope of the line is positive.
Answer:
61.8 and 118.2
Step-by-step explanation:
Let's call one angle A and the other B. Supplementary angles add to 180, so A+B=180. If B=A+56.4, then we can rewrite the equation in terms of A, or A+(A+56.4)=180 or 2A+56.4=180. To solve, first subtract 56.4 from each side and then divide by 2 to get A=61.8. Since the angle is supplementary, all we need to do to find B is subtract A (61.8) from 180 to get B=118.2.
Answer:
Kalino would need to earn at least a 97 on his fifth test.
Step-by-step explanation:
The average is calculated by adding up the amounts earned on each test and dividing by the total number of tests. In this case, the score for the last test is not known, but the expected average of 90 points is, so we can set up an equation to solve for the unknown test value:
'x' represents the score of the fifth test. Using inverse (opposite) operations and doing the same operation to both sides of the equation, we can first multiply both sides by 5:
x 5 = 90 x 5
353 + x = 450, now subtract 353 from both sides: 353 -353 + x = 450 - 353
x = 97
Answer:
<h3>18 units</h3>
Step-by-step explanation:
The Quadrilateral is a parallelogram.
Since Sides K L and J M are parallel and sides J K and L M are congruent, then the line drawn from J to L i.e JL will be equal to the line drawn from K to M i.e KM
In short the diagonal line JL will also be equal to the diagonal line KM. Since from the question we are given the length of J L to be 18 and JL = KM, hence the numerical length of KM will also be 18 units.
