Answer:
The number of fast songs is 64 and the number of slow songs is 32
Step-by-step explanation:
∵ Y represents the number of fast songs
∵ x represents the number of slow dance songs
∵ John gets to play a total of 96 songs at his school dance
→ That means the sum of x and y is 96
∴ x + y = 96 ⇒ (1)
∵ He wants twice as many fast songs, y, as slow dance songs, x
→ That means y is twice x
∴ y = 2x ⇒ (2)
→ Substitute y in equation (1) by equation (2)
∵ x + 2x = 96
∴ 3x = 96
→ Divide both sides by 3 to find x
∴ 
∴ x = 32
→ Substitute the value of x in equation (2) to find the value of y
∵ y = 2(32)
∴ y = 64
∴ The number of fast songs is 64 and the number of slow songs is 32
Answer:
the answer is €74£ and if you dont get dats juss u get it together
Top angle = 180-112 = 68
Bottom angle = 180 - 126 = 54
Sum of angles in a triangle = 180 sooo
68+54+m=180
122+m=180
m=180-122
m=58
Therefore, angle m = 58
Step-by-step explanation:
Hey, there!!
you number is: 81/625
We know that,
81=9×9
and
625=25×25
and............................................................
9×9 means 9^2
and 25×25 means 25^2
so, the exponential form of the question is,
=
{we simply find exponential form by finding their fraction}

ABCD is a parallelogram =>
∡A = ∡C
∡B = ∡D
∡A + ∡B = 180° } => ∡A = 180° - 41° = 139°
∡B = 41°
∡A = ∡C = 139°
∡B = ∡D = 41°
