Answer:
Step-by-step explanation:
Discount = % discount × cost price given.
Discounted price = cost price - discount
% discount = 30%
cost price given = $16
Discount = % discount × cost price given.
= (30/100) × $16
= $4.8
Giveaway price = $16 - $4.8
= $11.2
Answer:
Step-by-step explanation:
1) ∠1 + 33 = 180 {Straight line}
∠1 = 180 - 33
∠1 = 147
2){Exterior angle of a triangle equals the sum of opposite interior angles}
∠2 = 47 + 33
∠2 = 80
3) ∠2 +x = 180 {straight line}
80 + x = 180
x = 180 - 80
x = 100
{Exterior angle of a triangle equals the sum of opposite interior angles}
∠3 = 100 + 48
∠3 = 148
Answer:-2
Step-by-step explanation:
(n + 3) 5 = 3 x 1 - n
distribute so 5n + 15= 3 - n
subtract three from both sides
5n - 12 = -n
subtract 5n from both sides
12 = −6n
Divide both sides by -6
n=-2
Answer:
It's 21.
Step-by-step explanation:
The factors of 9 are 3 and 3. (You need to multiply 3x3 to get 9.) The factors of 10 are 5 and 2. But, if you multiply 3 by 5, which gives you 15, and multiply the other 3 by 2, which gives you 6, and then add 6 to 15, you get 21.
