Let the length of the 1st line segment = x

then the length of the second line segment = 4x + 5

The difference in their lengths = 35

so 4x + 5 - x = 35 ... [longer - shorter = 35]

3x = 30

x = 10

so the shorter (1st) line segment is 10 cm long

and the longer (2nd) line segment is 4 * 10 + 5 = 45 cm long

kari74 [83]

Answer:

$W = 16$

$T = 67$

Step-by-step explanation:

Represent trees with T and wreaths with W

Given

$T = 3 + 4 * W$

$2 * W + T = 99$

Solving (a): Cost of W

Substitute 3 + 4 * W for T in the second equation

$2*W + 3 + 4 * W = 99$

$2W + 3 + 4 W = 99$

Collect Like Terms

$2W + 4 W = 99 - 3$

$6W = 96$

Divide through by 6

$W =\frac{96}{6}$

$W = 16$

Hence, each wreath costs $16

Solving (b): Cost of T

$T = 3 + 4 * W$

Substitute 16 for W

$T = 3 + 4 * 16$

$T = 3 + 64$

$T = 67$

Hence, each tree costs $67
