the sum of supplementary angles is 180 degree

therefore

x +2x = 180°

3x = 180

X = 180/3 = 60°

the value of X is 60°

Need help solving this problem:

$24,000 ---------> City or State Bank
$3,000 < City Bank < $11000
State Bank< $18,000
City Bank = .06 of interest
State Bank = .11 of interest

<u>Bold</u>= Answer

<u>State Bank - (18, 000)(.11)-----> $1980</u>
<u>      } Total Interest = $2,430</u>
<u>City Bank - (6000)(.06)---------->$ 360 </u>
____________________________________________________________________
State Bank - (13000)(.11) ----------> $1,430
   } Total Interest = $2,090
City Bank - (11000)(.06) -------------> $660
____________________________________________________________________
State Bank- (17000)(.11) ---------->$ 1870
   } Total Interest = $2,290
City Bank- (7000)(.06) ---------------->$ 420

If 20 wall paintings can be done in 4 weeks how much time does it take to prepare 80 wall paintings using unit rate form?

In-s [12.5K]

Simplest way would be to find out how many painting more it would be 80 from 20. It is four times more drawings. Now since you know it is 4x more then you can simply multiply 4 time 4 (4*4) because it would be the weeks it takes him by the times it would be. It would be 16 weeks in total.

The number of loaves of bread purchased and the total cost of the bread in dollars can be modeled by the equation c = 3. 5b. Whi

Allisa [31]

You can use the fact that number of breads purchased cannot be negative since a customer either buys them or not and usually do not sell to the shopkeeper.(if somehow they end up selling to shop owner, then yes that will go in negative, but we'll assume it is wrong in most cases as generally shop owners are there to sell stuffs).

The third table of values matches the equation and includes only viable solutions.

<h3>What is a viable solution here?</h3>

It is talking about those solutions which are seen in real world. As stated above, a customer either buys the bread or not, thus number of breads sold will be either positive or 0(in case of no selling). Thus, we cannot have number of breads as negative.

Such solutions which are correct in the real world context here are called here as viable solutions.

<h3>Checking one by one all the tables for them being matched with table and viability</h3>

For first table, the number of breads are in negative, thus it is not going to have viable solution.

For second table, we have:

b = 0 thus c = 3.5b = 3.5 times 0 = 0 which is correctly given in second column.

b = 0.5, thus c = 3.5b = 3.5 times 0.5 =1.75 which is correctly given.

b = 1, thus c= 3.5 times 1 = 3.5 which is correctly given

b = 2001.5 thus c = 3.5 times 2001.5 = 7005.25 which is not correctly given, thus wrong.

For third table, we have:

b = 0, thus $c = 3.5 \times 0 = 0$ , correctly given in second column.

b = 3, thus $c = 3.5 \times 3 = 10.5$ , correctly given.

b = 6, thus $c = 3.5 \times 6 = 21$ , correctly given.

b = 9, thus $c = 3.5 \times 9 = 31.5$ , correctly given.

Thus, the third table of values matches the equation and includes only viable solutions.
