Step by step
5x+2y=9
Move variable to the right side and change
It’s side.
5x=9-2y
Divide both sides of the equation by 5
X = 9/5 - 2/5y
Final solution
Answer: x = 9/5 - 2/5y
Answer: the number is 369
Step-by-step explanation:
Let the missing number be y
8/9 × y = 328
8/9y = 328
Divide both sides by 8/9
y = 328 ÷ 8/9
y = 328 × 9/8 (multiply the two numerators: 328 x 9= 2952
Multiply the denominator by 1: 8 x 1= 8
Therefore y = 2952/8
y = 369
I hope this helps.
∠2 = ∠3 | Given
∠1 + ∠2 = 180 | Supplementary Angles Postule (If two angles are adjacent and ∠3 + ∠4 = 180| linear, they're supplementary)
∠1 + ∠2 = ∠3 + ∠4 | Transitive property
∠1 + ∠3 = ∠3 + ∠4 | Substitution property
∠1 = ∠4 | Subtraction Property
∠2 = ∠3 | Supplementary Congruent Theorem
