The 3 bubble is the correct answer.

being that you're looking for 3.60 in quarters(25) and nickles (5) which add up to be 3.60 so 25q+5n=360
Maru [420]3 years ago

For 1 I would set it up like this:
360 = 5q + 5n

For 2 I would put cost per mile because it's multiplied by the number of miles.

For 3 I would say the customers purchased 5 kid tickets and 4 adult tickets 

For 4 I would do this:
P = each can of paint
and 
B = each bush

25P + 12.75B = 327

For 5 I would say that 2 represents the amount of waffle cones and 3 represents the amount of milkshakes.



As always, I hope this helps!

A woman bought some large frames for ​$18 each and some small frames for ​$8 each at a closeout sale. If she bought 21 frames fo
IrinaVladis [17]

Answer:

<em> 8 large frames and 13 small frames</em>

Step-by-step explanation:

<u><em>Given:</em></u><em>
$18 each = large frames</em>

<em>$8 each = small frames</em>

<u><em>To Find:</em></u>

<em>⇒  Bought 21 frames for ​$​248, find how many of each type she bought</em>

<u><em>Solve:</em></u>

<em>1 Large frame costs = 18 $</em>

<em>Therefore, x large frames costs = 18x $</em>

<em>{where x is the number of large frames she bought}</em>

<em>1 Small frame costs = 8 $</em>

<em>Therefore, x Small frames costs = 8y $</em>

<em>{where y is the number of small frames she bought}</em>

<em>By the given condition :</em>

<em>18x + 8y = 248        {equation 1}</em>

<em>x + y = 21                 {equation 2}</em>

<em>Solve these equations simultaneously, from second equation we get :</em>

<em>x = 21- y</em>

<em>18⋅(21−y)+8y= 248</em>

<em>378 - 18y+8y = 248</em>

<em>-10y = -130</em>

<em>y = 13</em>

<em>Put y = 13 in eq x = 21- y</em>

<em>x = 21  - y</em>

<em>x = 21 - 13</em>

<em>x = 8</em>

<em>So the woman bought 8 large frames and 13 small frames.</em>

16. Prove that the sum of three angles of triangle is two right angles.​
Reptile [31]

Answer:

Two right angles = 180 degrees

Step-by-step explanation:

A right angle = 90 degrees

The sum of the interior angles of a triangle = 180 degrees

Two right angles (2 * 90) = 180

180 = 180

Therefore, the sum of the interior angles of  any triangle is equal to two right angles.
