Step-by-step explanation:
He has 24 books! 2 dvds for every 8 books equals 1 dvd for every 4 books. 6 dvds times 4 books (6x4) equals 24.
Answer:
Taylor's age = x = 35 years
Marty's age = y = 50 years
Step-by-step explanation:
Let
Taylor's age = x
Marty's age = y
Taylor is 15 years younger than Marty.
x = y - 15
Twice Marty’s age added to three times Taylors age totals 205.
205 = 2y + 3x...... Equation 1
Therefore, we substitute y - 15 for x in
205 = 2y + 3x...... Equation 1
205 = 2y + 3(y - 15)
205 = 2y + 3y - 45
Collect like terms
205 + 45 = 5y
250 = 5y
y = 250/5
y = 50 years
x = y - 15
x = 50 - 15
x = 35 years
Solving for x
Therefore:
Taylor's age = x = 35 years
Marty's age = y = 50 years
Answer:
Step-by-step explanation:
by inspection
angles 2 and 3 are equal, so they will be half angle ABC
angles 1 and 5 are equal so they will be
angle 1 + angle 5 + angleABC = 180° kind of a rule for triangle
the sum of all angles - 180°
(angle 1) x 2 = 180° - 70°
angle 1 = 90° - 35°
angle 1 = 55° which equals angle 5
angle 4 is clearly a right angle 90°
DO the same procedure for the bottom triangle
angle 8 and 9 are half of angle ADC
angle 8 and 9 are half of 46°
both are 23°
angle 6 equals angle 7
2 ×angle 6 = 180° - 46°
angle 6 = 90° - 23°
angle 6 = 67° angle 7 = 67°
