1. Segment A'B' is parallel to segment AB. What is the length of segment BB'?

ella [17]

Answer:

A. 3.5

Step-by-step explanation:

Given that AB is parallel to A'B', therefore,

CB/CB' = CA/CA'

CB' = 7

CB = CB' + BB' = 7 + BB'

CA' = 6

CA = CA' + AA' = 6 + 3 = 9

Plug in the values

(7 + BB')/7 = 9/6

(7 + BB')/7 = 3/2

Cross multiply

2(7 + BB') = 7(3)

14 + 2BB' = 21

Subtract 14 from both sides

2BB' = 21 - 14

2BB' = 7

Divide both sides by 2

BB' = 7/2

BB' = 3.5

Solve the simultaneous equations 4x + 3y = 20 4x + 2y = 14

fiasKO [112]

Step-by-step explanation:

$\underline{ \underline{ \text{Given}}} :$

$\tt{4x + 3y = 20........... \text{ equation \: ( \: i \: )}}$
$\tt{4x + 2y = 14.......... \text{equation \: (ii)}}$

$\underline{ \text{USE \: ELIMINATION \: METHOD}} :$

Subtract equation ( ii ) from equation ( i ) :

Remember that the sign of each term of the second expression changes i.e equation ( i ) now becomes -4x -3y = -20

$\tt{ \cancel{4x }+ 2y = 14}$

$\tt{ \cancel{ - 4x} - 3y = - 20}$

__________________

$\tt{ - y = - 6}$

⟿ $\tt{ \boxed{ \tt{y = 6}}}$

Again , Substituting the value of y in equation ( ii ) :

⟿ $\tt{4x + 2 \times 6 = 14}$

⟿ $\tt{4x + 12 = 14}$

⟿ $\tt{4x = 2}$

⟿ $\boxed{ \tt{x = \frac{1}{2}}}$

$\red{ \boxed{ \boxed{ \tt{Our \: final \: answer : x = \frac{1}{2 } \: and \: y = 6}}}}$

Hope I helped ! ツ

Have a wonderful day / night ! ♡
