sum of all 3 angles inside a triangel is 180
1850000g(kg/1000g)-1525000g(kg/1000g)
1850kg-1525kg
325kg
I think it’s 51.6% because 8.3% interest at the rate of 6 years is just 8.3 multiplied by 6 which is 51.6
- AC is congruent to itself
- AC bisects angle BAD, so that angles BAC and DAC are congruent
- Both angles B and D are right angles, so they are congruent
This means triangles BAC and DAC are a pair of angle-angle-side triangles, so they are congruent to one another. Corresponding parts of congruent triangles are congruent, so the line segments BC and DC are congruent and have the same length.
Then
Given:
James bought 22 candy bars for $137.
If the king size candy bars cost $8 and a regular size candy bar cost $5.
To find:
The system of equation and solution of it.
Solution:
Let x be the number of king size candy and y be the number of regular size candy.
Quantity: ...(i)
Cost : ...(ii)
Multiply the equation (i) by 5.
...(iii)
Subtract (iii) from (ii).
Put x=9 in (i).
Therefore, number of king size candy is 9 and number of regular size candy is 13.
