Answer:
the solution set is r>7
step by step:
Subtract 3 from both sides
3−3r−3<−2r−4−3
Simplify
−3r<−2r−7
Add 2r to both sides
−3r+2r<−2r−7+2r
Simplify
−r<−7
Multiply both sides by −1 (reverse the inequality)
(−r)(−1)>(−7)(−1)
Simplify
r>7
Answer:
1/4
Step-by-step explanation:
divide the value in feet by 5280 because 1 mile equals 5280 feet.
Answer:
son = 4
mom=36
m = 9s
m + 4 = 5(s+4)
m + 4 = 5s + 20
9s + 4 = 5s + 20
4s = 16
s = 4
m = 36
Step-by-step explanation:
Your gonna wanna multiple (5/8)(5/8) which is 25/64 or about 39 percent. (I might not be entirely right, sorry. )
The square of an odd number:
We're to conjecture, not do algebra, apparently. 1²=1, 3²=9, 5²=25, 7²=49, ...
We conjecture the square of an odd number is odd.
The product of two evens and an odd:
Again, we'll run some examples.
(2)(2)(1)=4
(2)(4)(3)=24
(4)(6)(5) =120
(4)(8)(1)=32
Conjecture: The product of two evens and an odd is a multiple of 4
Counterexample: The product of two fractions is never an integer
How about
3/4 × 4/3 = 1
