Answer:
Option (1)
Step-by-step explanation:
Length of a rectangle = (5.9d + 8.3f) cm
Width of the rectangle = (7.3d + 2.2f) cm
Since formula to get he perimeter of a rectangle is,
Perimeter = 2(length + width)
= 2[(7.3d + 2.2f) + (5.9d + 8.3f)]
= 2(13.2d + 10.5f)
= (26.4d + 21f) cm
Therefore, Option (1) will be the correct option.
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
