Those two angles total equal 180 degrees.
Since we know the first angle equals 155 degrees.
180-155+25.
ABC is 25 degrees.

< CBD = 155
< CBD and < ABC are supplementary angles which, when added = 180

so...< CBD + < ABC = 180
155 + < ABC = 180
< ABC = 180 - 155
< ABC = 25 <===

At a bargain store, Tanya bought 3 items that each cost the same amount. Tony bought 4 items that each cost the same amount., bu

TEA [102]

Answer: Let x represent the cost of one of Tanya's items.

Then the cost of one of Tony's items =x - 2.25. But we have:

3x =4(x - 2.25)

3x =4x - 9 subtract 3x from both sides

0 =x - 9 add 9 to both sides

x=$9 The cost of one of Tanya's items

27 Total cost of Tanya's 3 items

2.25 =$6.75 cost of one of Tony's items.

27 Total cost of Tony's 4 items.

3 x 6.75 =$27. This shows that both Tony and Tanya spent the same amount of money.

Serga [27]

Answer:

It will take a total of twenty minutes

Step-by-step explanation:

if it cools from 200 to 195 in five minutes then times two is twenty which means it's cooled to 190.

180 is twenty less then 200 so if it takes ten minutes to cool down by ten then multiply this by two and you get 180 and know it's cooled by twenty minutes
