The answer is 260. 260 times 36% is equal to 93.6
Answer:
28
Step-by-step explanation:
so there are 7 days in a week and she had 4 stickers left so 7 x 4 = 28.
Answer:
she has 12 - D quarters.
She has 24 (12-D) cents in quarters
Step-by-step explanation:
You know that the number of coins, and you know the number of dimes - even if the amount is a variable - you can find the amount of quarters with an equation.
If you knew that Lina had 6 dimes instead of D, you would say 12 - 6 and get the number of quarters. You can do the same thing here.
and If you know Lina has 6 quarters, you could find the amount of money in cents by multiplying 6 by 25. You can do that here too, but with variables and an equation.
Answer:
x = 71°
Step-by-step explanation:
The angles of any triangle will always amount to 180°.
Which means: (Angle of A) + (Angle of B) + (Angle of C) = 180°
Placing the known values into that equation will always let you know the third angle of any triangle.
(Angle of A) + (Angle of B) + (Angle of C) = 180°
(38°) + (71°) + (x) = 180°
109° + x = 180°
Solve for x by subtracting 109° from both sides
x = 180° - 109°
x = 71°
OR you can add the other two known angles 38° + 71° = 109°
This subtracted from the 180°
180° - 109° = 71°
Give the 2 numbers variables,say x and y.
then they multiply to -225.this means xy=-225
they add to 16.this means x+y=16
y=16-x
substitute y=16-x onto xy=-225 to get x(16-x)=-225
then expand to get 16x-x^2=-225
rearrange to get a quadratic: x^2-16x-225=0
x=(16+(16^2-4*-225)^0.5))/2 or
x=(16-(16^2-4*-225)^0.5))/2
