Step-by-step explanation:
For the triangle on the bottom right the missing angle is
180- (74+50)= 56°
For the triangle on the bottom left the missing angle is
180- (45+80)= 55°
For the triangle in the middle the missing angle is
180- (54+51)= 75°
For the triangle on top the missing angle is
180- (80+54)= 46°
180- (74+51)= 55°
180- (46+55)= 79°
9+6=15 and 15-12=3 so this =3 the -(-6) becomes positive
Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
-5/3, -0.1, 0.7, sqrt2, sqrt5
<u>Answer</u>
18) $51
19) $24
20) <em> Carla's account. </em>
<u>Explanation</u>
18)
Positive sign values means deposit while the negative values means money been withdrawn from the account.
$100 - $18 + $22 - $53 = $51
19)
Positive sign values means money deposited while the negative values means money been withdrawn from the account.
$45 - $17 - $22 + $18 = $24
20)
To get the person with the most deduction, you should add the negative values in the table then compare.
Carla ⇒ -18 + -53 = $-71
Leta ⇒ -17+ -22 = $-39
From here we can see that the account with greatest decrease is<em> Carla's account. </em>
