Answer:

10 and 170 degrees.

Step-by-step explanation:

If the angle is x degrees then its supplementary angle = 180-x degrees.

So x + 17x = 180

18x = 180

x = 10 degrees.

Answer:

The measure of each angle will be 10° and 170°.

Step-by-step explanation:

A supplementary angle refers to an angle that has the sum to be equal to 180°.

Let the small angle be represented by x

Therefore, the big angle will be: = 17 × x = 17x

Therefore, the value of both angles will be:

x + 17x = 180

18x = 180

Divide both side by 18

18x/18 = 180/18

x = 10

Therefore, the bigger angle will be:

17x = 17 × 10 = 170

Therefore, the angles are 10° and 170°

Breyanna is buying a new dress .The dress is on sale for 20% off.Breyanna will also have to pay 10% sales tax on the discounted

Nuetrik [128]

Hi,
Let x be 100 dollars(since per cent means out of 100)(also SP)
SP without sales tax= 100 - d%/100 * SP
= 100-20/100 * 100
=80/100 * 100
= 0.8 * 100
= 80 dollars=SP without tax
tot. SP(SP with tax)= 100 + tax%/100 * SP
=100 + 10 /100 * 80
= 110/100 * 80
= 11/10 * 80
=1.1* 80
=88%
Breyanna will have to pay 88% of the dress original price.
Hope this helps you.

Y= x-v/b Solve for x

jeyben [28]

Answer:

x = y*b + v

Step-by-step explanation:

y=(x-v)/b

Multiply by b on both sides,

y*b = x-v

Add v on both sides,

x = y*b + v

Answer:

Option A

Step-by-step explanation:

angles ABD and DBC are complementary given

angle ABD=50 degrees given

angles ABD and DBC = 90 degrees def. of complementary

angle DBC = 40 degrees algebra (90-50=40)

angles EBF and ABD are vertical angles vertical angles postulate

angle EBF is congruent to angle ABD def. of vertical angles

angle EBF = 50 degrees def. of congruence

angles EBF and ABF are a linear pair def. of linear pair

angles EBF and ABF are supplementary def. of linear pair

angles EBF and ABF = 180 def. of supplementary

angle ABF = 130 degrees algebra (180-50=130)

angles ABF and EBD are vertical angles vertical angles postulate

angles ABF and EBD are congruent def. of vertical angles

angle EBD = 130 degrees def. of congruence

angles CBE + DBC = EBD diagram

angles CBE + DBC = 130 degrees transitive property of congruence

angle ABD = 90 algebra (130-40=90)

B is needed in the process, but the main statement that actually does the justification is A, so option A

3. The manager of a store marks up all the items by 10%. If x is the original price, which expression represents the new price w

goldenfox [79]

Answer:
1.1x
x + 0.1x

Step-by-step explanation:

The manager of a store marks up all items by 10%.

So, if the original price of any item is x, then increase for markup is 10% of x i.e. .
Hence, the expression that represents the new price with the markup is (x + 0.1x) = 1.1x.
