At a certain college, the ratio of men to women is 6 to 5. If there are 1,500 men, how many women are there?
Fed [463]

Let 6x represent the men

5x represents the women

The ratio of men to women is 6 to 5 or 6/5


6x / 5x = 1500/ W  where W is the number of women

6/5 = 1500/W

W =  1250 women

Tim predicts he will get 98 points on the next exam. If Tim actually earned 62 points, what was Tim's percent error? Round your
cupoosta [38]
% change= (new # - original #) ÷ original # x 100

original #= 98
new #= 62

% change= (62-98)/98 x 100
= -36/98 x 100
= -0.36734 x 100
= -36.73%

Rounded to nearest 10th of %= -36.7%

CHECK:
= 98 - (98 * 36.73%)
= 98 - (98 * 0.3673)
= 98 - 36
= 62 new #

ANSWER:
Her percent error was 36.7% (rounded to the nearest tenth of a percent). The negative indicates a decrease.

Hope this helps! :)

What is 5( x - 3 ) = 5x - 15?
Volgvan

\tt5( x - 3 ) = 5x - 15 \\  \tt5x - 15 = 5x - 15 \\ \tt5x - 5x =  - 15 + 15 \\ \tt\bcancel{5x} - \bcancel{5x} =  \bcancel{- 15} + \bcancel{15} \\ \boxed{\tt0 = 0}

  • The answer is <u>0</u><u>.</u>
  • LHS = RHS, hence verified.

<u>Value of x (substitute 0 in the place of x).</u>

\tt5( (0) - 3 ) = 5(0) - 15 \\  \tt0 - 15 = 0 - 15 \\  \tt \boxed{\tt -15 = -15}

  • So, value of x is <u>0</u><u>.</u>

My sister needs help!
Lunna [17]
Idk if she's too young to learn cross multiply, but this is an easier method.

Multiply everything by 4 which cancels out the 4 on the left side.
36z-16/5 <= 7z + 2
Now multiply everything by 5, cancelling out the right side 5.
36z-16 <= 35z + 10
Solve the equation normally
z-16<=10

z<=36
