Hello from MrBillDoesMath
Answer: + 4/7, 6 (13/14)
Discussion:
Let L be the larger of the two numbers and S the smaller of the two. Then the first sentence translates into this:
-6L - L = -4 =>
-7L = -4 => (divide both sides by -7)
L = - (-4)/(-7) = + 4/7 (*)
The second sentence translates to
2 (L + S) = 15 => (divide both sides by 2)
(L +S) = 15/2 => (subtract L from each side)
S = 15/2 - L = 15/2 - 4/7 (using (*) above)
So
S = 15*7/(2*7) - (4*2)/(7*2) (combine over common denominator of 14)
S = 105/14 - 8/14 = 97/14 = 6 13/14
Something is crazy here! While 2(L +S) = 15 -- check it out -- our larger number L ( =4/7) is actually smaller than the S number (6 13/14)! Maybe I should have called them Y and X, respectively, as you suggested!
Thank you,
Mr. B
There are two pairs of equal matching angles. One pair is marked, the pair of 15 degree angles. The other pair are the vertical angles formed by the intersecting lines.
Answer:
2 2/5
Step-by-step explanation:
−1 3/5 / −2/3
=2 2/5
(Decimal: 2.4)
i hope this helps
brainliest is very much appreciated... :}
I think the first one is correct. Since “three less than z squared” insinuate that the value is 3 units less than the value z^2
