Answer:
C
Step-by-step explanation:
Add like terms to get
4.5a + 4b + 3.5c
Make an equation
X+X+200=1500
Isolate the variable
2x=1300
X=650
Know that we know what X is, we know that X + 200 will equal the cost of the second appliance
650+850=1500
The cost will be <u>$20.40</u>
<h3>
EXPLANATION</h3>
10% of $28 = $2.80
10% x 2 = $5.60 = 20%
$5.60 + $2 = $7.60
$28 - $7.60 = <u>$20.40</u>
Hope this helps!
Answer:
B. Vertical angles.
look at the image attached.
Answer:
x=30°
Step-by-step explanation:
Because of the given congruency,
Angle A = Angle D = 65°.
Angle C = 55°
Angle B = Angle E = 2x
Now, In Triangle ABC,
Angle A + Angle B + Angle C = 180°.
65° + 2x + 55° = 180°
120 + 2x = 180
2x = 60
x = 30°
HOPE IT HELPS!!!
