5 c + 3 = 18 Subtract 3 to both sides. 5 c = 15 c = 15 / 5 c = 3
tan ( 2 θ ) = 2 tan θ / ( 1 - tan² θ ) tan ( 2 θ ) = 24 / 7 2 tan θ / ( 1 - tan² θ ) = 24 / 7 Divide both sides by 2. tan θ / ( 1 - tan² θ ) = 12 / 7 Cross multiply. tan θ • 7 = ( 1 - tan² θ ) • 12 7 tan θ = 12 - 12 tan² θ Add 12 tan²
Multiply numerator and denominator by 5. 3 / 20 = 5 • 3 / 5 • 20 = 15 / 100 = 0.15
Since: 1,700 = 1.7 • 1000 and 1,000 = 10 ³ 1,700 = 1.7 • 1000 1,700 = 1.7 • 10 ³
A rational number is a number that can be expressed as the fraction : p / q where p and q are two integers 0.123123... because: 1000 • 0.123123 - 0.123123 = 123.123123... - 0.123123... 999 • 0.123123...= 123 Divide both sides by 999. 0.123123... = 123
Subtract 999 to both sides. k = 722
Add 53.1 to both sudes. g = 66.5
A rational number is a number that can be expressed as the fraction : p / q where p and q are two integers π , √2 , and √3 are not a rational numbers If 1 point modifying above 3 with bar means 1.3333 then that is 4 / 3. 4 / 3 is a rational number.
Composite number is whole number that can be made by multiplying other whole numbers. 25 = 5 • 5
Subtract 354 to both sides. r + 354 - 354 = 1,321 - 354 r = 967
Cross multiply. 8 • p = 6 • 7 8 p = 42 p = 42 / 8 = 2 • 21 / 2 • 4 = 21 / 4 p = 5.25
( 200 - 180 ) / 200 • 100% = 20 / 200 • 100% = 0.1 • 100% = 10% OR Difference of prices = $200 - $180 = $20 $20 is 10% of $200
5.82 / 8 • 1.72 = 10.0104 / 8 = 1.2513 Each piece cost $1.25 rounded to one cent.
1 / 2 is same as 3 / 6 1 / 2 - 1 / 6 = 3 / 6 - 1 / 6 = 2 / 6 = 2 • 1 / 2 • 3 = 1 / 3 1 / 3 cup is left
6 • 10⁴ = 6 • 10 000 6 • 10⁴ = 60 000
x = number 3 / 4 x + 3 1/2 = 6 1/2 - 2 / 3 x 3 x / 4 + 3 + 1 / 2 = 6 + 1 / 2 - 2 x / 3 3 x / 4 + 6 / 2 + 1 / 2 = 12 / 2 + 1 / 2 - 2 x / 3 3 x / 4 + 7 / 2 = 13 / 2 - 2 x / 3 Add 2 x / 3 to both sides. 3 x / 4 + 2 x / 3 + 7 / 2 = 13 / 2 Subtract 7 / 2 to
x = number x / 4 + 4 1/3 = 20 2/3 - x / 3 x / 4 + 4 + 1 / 3 = 20 + 2 / 3 - x / 3 x / 4 + 12 / 3 + 1 / 3 = 60 / 3 + 2 / 3 - x / 3 x / 4 + 13 / 3 = 62/ 3 - x / 3 Add x / 3 to noth sides. x / 4 + x / 3 +13 / 3 = 62 / 3 Subtract 13 / 3 to both sides. x / 4 + x
300 / 250 = 50 • 6 / 50 • 5 = 6 / 5
x = number 1 / 6 x - 2 = 5
His savings = 5400 - 4500 = 900 The ratio of his income to his savings = 5400 / 900 = 6 • 900 / 900 = 6
2 / 3 x + 4 and 2 x are two linear equations. Two linear equations, if they do not have the same slope, have only one point of contact, i.e. their value is equal only at one point. Slope of first equation is 2 / 3. Slope of second equation is 2. So their
b = boys g = girls There are 160 people in a grade means: b + g = 160 Subtract b to both sides g = 160 - b The ratio of boys to girls is 3 to 5 means: b / g = 3 / 5 Replace g with 160 - b in this equation. b / ( 160 - b ) = 3 / 5 This is a proportion. The
6 = 4 x + 9 y Subtract 4 x to both sides 6 - 4 x = 9 y Divide both sides by 9 6 / 9 - 4 x / 9 = y 3 • 2 / 3 • 3 - 4 / 9 x = y 2 / 3 - 4 / 9 x = y y = - 4 / 9 x + 2 / 3
