Answer:
5 3/4
Step by step explanation:
Find a common denominator in this case is 4 so instead of adding 2 1/2 to 3 1/4 it’s going to be 3 1/4 + 2 2/4 which gets you 5 3/4
Answer:
A. 2x + 5(2x + 6) = 12x + 30
Step-by-step explanation:
Infinitely many solutions means the two sides of the equation will be equal to each other, so B and D can be eliminated. Distribute for A and C to check
A. 2x + 5(2x + 6) = 12x + 30
2x + 10x + 30 = 12x + 30
12x + 30 = 12x + 30
C. 2(x + 5) + 2 = 6x + 2(x + 2)
2x + 10 + 2 = 6x +2x + 4
2x + 12 = 8x + 4
You only get the same equation for A, therefore A is the correct answer
Answer:
the points of the graph
Step-by-step explanation:
there is a rule for every rotation for example a 90 degree rotation's rule is A(x,y) = A'(-y,x) to use them you need to have the points
Answer:
The measure of these two angles are 80° and 100°
Step-by-step explanation:
Let
x and y ----> the measure of the same side angles
we know that
The sum of of the same side angles of two parallel lines is equal to 180 degrees
x+y=180° -----> equation A
x=y-20° ----> equation B
substitute equation B in equation A and solve for y
(y-20°)+y=180°
2y=180°+20°
y=200°/2
y=100°
Find the value of x
x=100°-20°=80°
