Answer:
x + 49 + 28 = 180
Step-by-step explanation:
The angles on a straight line with x° are 28° and 49° respectively, side by side with x°. This is because, vertical angles are equal. Therefore, the angle vertically opposite 28° and 49° are equal to 28° and 49° respectively.
Therefore, since angles on a straight line is 180°, thus:
x + 49 + 28 = 180
Answer:
when u divide both side by 2 the new equation will be y-5x=-3... and equation of a line is written in form of y=mx+c
so y=5x-3
Answer:
AB = 6.4
Step-by-step explanation:
Assuming that AB + BC is AC, then we can say the following:
AB + BC = AC
AB + 6.8 = 13.2
AB + 6.8 + -6.8 = 13.2 + -6.8
AB = 6.4
Cheers.
Answer:
False, B
Step-by-step explanation:
The relationship between the cost of books and pens is an illustration of linear equation.
The linear equation is (a) 
From the question, we have:
x exceeds 2 times y by 10
Rewrite as:
x exceeds 2y by 10
Exceed means plus (+)
So, we have:
Equate the above equation to 0
Hence, the required equation is (a)
