Hi! The answer is 231.25.
The answer is 231.25 because 8,325 / 36 is 231.25 I hope this helped! Goodluck :)
A’B’ and AB are equal in lenght
When we rotate an object it’s length does not chance only it’s position.
(270 degrees it means you rotate 3 times)
Answer:
J - Janeta's age M - mother's age
A) (J-5) = .2 * (M-5)
B) J = (1/3) * M
Subtracting 5 from both sides of B:
B) J -5 = (1/3)M -5
then we substitute the right side of this into the left side of A and we get
(1/3)M -5 = .2 M -1
.333333333333M -5 = .2M -1
.1111111111111111111M = 4
Mother's Age = 36
Janeta's Age = 12
Step-by-step explanation:
Step-by-step explanation:
the small and the large triangles are similar triangles.
they have the same angles. and the corresponding sides correlate to each other with the same ratio for every pair of sides.
so,
28 / 82 = (2x + 8) / ((2x + 8) + (5x -4)) =
= (2x + 8) / (7x + 4)
(7x + 4)×28 = (2x + 8)×82
196x + 112 = 164x + 656
32x = 544
x = 17
A) x + 4y = -15
B) -2x -8y = 30
Multiplying A) by 2
A) 2x + 8y = -30
This has NO solution because A) and B) are actually the same equation.
Equation B = Equation A times minus 2.
