Answer:
a) ∠TVZ= 95°
Step-by-step explanation:
3a) ∠STY= ∠QTV (vert. opp. ∠s)
3x°= 120°
x°= 120° ÷3
x°= 40
∠TVZ= ∠RVW (vert. opp. ∠s)
∠TVZ= (2x +15)°
∠TVZ= [2(40) +15]°
∠TVZ= (80 +15)°
∠TVZ= 95°
b) Since ∠TVZ and ∠WVZ lies on a straight line,
∠TVZ +∠WVZ= 180° (adj. ∠s on a str. line) -----(1)
∠WVZ= (2x +5)°
∠WVZ= [2(40) +5]°
∠WVZ= (80 +5)°
∠WVZ= 85°
Substitute ∠WVZ= 85° into (1):
∠TVZ +85°= 180°
∠TVZ= 180° -85°
∠TVZ= 95°
Thus, ∠TVZ is indeed 95°.
Notes:
• What is vert. opp. ∠s?
It is an abbreviation used for a property of angles, vertically opposite angles. When two lines intersect each other, the angles facing each other (or the angles on the opposite side of each other) are equal.
• What is adj. ∠s on a str. line?
It is an abbreviation for 'adjacent angles on a straight line'. The sum of all the angles on a straight line is 180°.
One burrito salad costs $8.49 and one tortilla salad costs $3.59
Step-by-step explanation:
Let,
x be the cost of one burrito
y be the cost of one tortilla
According to given statement;
2x+y=20.57 Eqn 1
3x+3y=36.24 Eqn 2
Multiplying Eqn 1 by 3
Subtracting Eqn 2 from Eqn 3
Dividing both sides by 3
Putting x=8.49 in Eqn 1
One burrito salad costs $8.49 and one tortilla salad costs $3.59

Step-by-step explanation:
<u>INFORMATION:</u>
The slope-intercept is when y=mx+b
mx=the slope
b=y-intercept
<u />
<u>REPHRASE EQUATION:</u>
y=mx+b
y=-3-x
y=(-1)x-3
<u>CONCLUSION:</u>
Slope=-1
Y-intercept=-3
