∠ a: x
∠ b: x
∠ c: x + 21
∠ d: x - 53
∠ a + ∠ b + ∠ c + ∠ d = 360 <em>sum of the angles of a rectangle is 360° </em>
(x) + (x) + (x + 21) + (x - 53) = 360
4x - 32 = 360
4x = 392
x = 98
∠ c: x + 21 = (98) + 21 = 119
∠ d: x - 53 = (98) - 53 = 45
Answer: ∠ a = 98°, ∠ b = 89°, ∠ c = 119°, ∠ d = 45°
Divide the number that islf can divide by like 2 or 3 or 4 for exaples
This would simply be 0.008 * 5700, because %'s are out of 100.
So the fee would be $45.60
Answer:
The class will pay $82.50
Step-by-step explanation:
The zoo is covering 60%.
The school is covering 25%.
60% + 25% = 85%
100% - 85% = 15%
That leaves 15% to be paid by the science class.
To figure out what 15% of $550, we can multiply $550 by 0.15.
$550 * 0.15 = $82.50
So, the class will pay $82.50

1). 16 Y= 164. ( then divided)
Y= 164 : 16
Y= 41 : 4
Y = 10 +1/4
2) 8z = 64. (then divided)
z= 64 :8
z= 8
3. D = A•B•C. ( divided)
D : A•B = C
C= D:AB
c. c= d divided by ab
