6 tens is the same as 60 so....
60 x 10 = 600
We know: The sum of the measures of the angles of a triangle is equal 180°.
We have: m∠A =65°, m∠B = (3x - 10)° and m∠C = (2x)°.
The equation:
65 + (3x - 10) + 2x = 180
(3x + 2x) + (65 - 10) = 180
5x + 55 = 180 <em>subtract 55 from both sides</em>
5x = 125 <em>divide both sides by 5</em>
x = 25
m∠B = (3x - 10)° → m∠B = (3 · 25 - 10)° = (75 - 10)° = 65°
m∠C = (2x)° → m∠C = (2 · 25)° = 50°
<h3>Answer: x = 25, m∠B = 65°, m∠C = 50°</h3>
The amount of Cute Puppy food needed for the year is 1140 cans.
<h3>Determining the total number of cans that the dogs eat in a year</h3>
The first step in determining the total number of cans needed in year is to calculate the sum of dog food consumed in a week.
8.25 + 15.5 = 23.75 cans
The second step is to determine the total cans the dogs consume in a month
23.75 x 4 = 95
The third second step is to determine the total cans the dogs consume in a year:
95 x 12 = 1140 cans
<h3>Cost of cute puppy food needed in a year</h3>
1140 x ($21 /40) = $598.50
