Get common denominators, and solve for each expression
7/5 - 3/4 = 28/20 - 15/20 = 13/20
1/4 + 2/5 = 5/20 + 8/20 = 13/20
These two fractions are equivalent
A is the point (-4, 1)
i) reflection over the y-axis projects a point (a, b) to (-a, b):
(-4, 1) is projected to (4, 1),
ii) reflection over the x axis projects a point (a, b) to (a, -b):
(4, 1) is projected to (4, -1),
iii) rotation 180 degrees: projects (a, b) to (-a, -b):
so (4, -1) is projected to (-4, 1)
Answer: A'(-4, 1)
So each house can hold 1000 cubes that are 1 meter in length. The house is also shaped like a cube, so you need to cube-root 1000. The cube-root of 1000 is 10. So the cube house has a length, width, and height of 10 meters.
Day 1 and Day 3 his score add up to zero.
Day 2 and Day 4 his score add up to zero.
Answer:
2^3 = 8
Step-by-step explanation:
2*2*2 = 8
16 - 8 = 8
8 / 2 = 4
4 + 9 = 13
13 may be your answer
