Elisa withdrew $20 at a time from her bank account and withdrew a total of $140. Francis withdrew $45 at a time from his bank ac

Tasya [4]

Answer:

Elisa made the greater number of withdrawals.

Step-by-step explanation:

Given that:

Elisa withdrew $20 at a time and a total amount of $140

Number of withdrawals by Elisa = $\frac{Total\ amount\ withdrawn}{Amount\ withdrawn\ each\ time}$

Number of withdrawals by Elisa = $\frac{140}{20}=7$

Francis withdrew $45 at a time and a total amount of $270

Number of withdrawals by Francis = $\frac{270}{45}$

Number of withdrawals by Francis = 6

On comparing;

7 > 6

Hence,

Elisa made the greater number of withdrawals.

A₁ = -6 + (1-1)(6) = -6 + 0 = -6
a₄ = -6 + (4-1)(6) = -6 + 3·6 = 12
a₁₀ = -6 + (10-1)(6) = -6 + 9·6 = 48

A) Work out the size of angle x.

kkurt [141]

Answer:

$x = 75\degree$

Step-by-step explanation:

$m\angle EFB +105\degree = 180\degree$

(linear pair angles)

$m\angle EFB = 180\degree - 105\degree$

$m\angle EFB = 75\degree$

$\because x = m\angle EFB$

(corresponding angles)

$\therefore x = 75\degree$
