The sale price would be $7.70. the sale is 30%off, so the discount would be o.3 x 11. The sale price itself would be 0.7 x 11. Therefore, 0.7x11 is $7.70 and that is the sale price
Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
Answer:
1%
Step-by-step explanation:
I assume since it’s .9% it’s less then 1%
So we'll assume the number is x.
So,
15+
= 9.
Now, we solve for x:
= 9-15
= -6
x = -6*2
x = -12
Check work:
15+
= 9
15+(-6) = 9
15-6 = 9
9 = 9
