Answer:
28 cm
Step-by-step explanation:
For the similar figures, a proportion can relate the side lengths.
x/(7 cm) = 11.2/2.8
x = (7cm)(11.2/2.8) = 28 cm
The value of x is 28 cm.
Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
y = - 5x + 6 → (1)
y = 3x - 2 → (2)
Since both equations express y in terms of x, equate the right sides
3x - 2 = - 5x + 6 ( add 5x to both sides )
8x - 2 = 6 ( add 2 to both sides )
8x = 8 ( divide both sides by 8 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 in (2)
y = 3(1) - 2 = 3 - 2 = 1
Solution is (1, 1 )
Answer:
21
Step-by-step explanation:
50 - 23.75 = 26.25
