Answer:
x=10
m=3
Step-by-step explanation:
The angles are the same since the sides are the same length (isosceles triangle)
55 = 5x+5
Subtract 5
55-5 =5x+5-5
50 = 5x
Divide by 5
50/5 = 5x/5
10=x
The altitude is a perpendicular bisector so
5m-3 = 2m+6
Subtract 2m from each side
5m-3-2m = 2m+6-2m
3m-3 = 6
Add 3 to each side
3m-3 +3 =6+3
3m =9
Divide by 3
3m/3 = 9/3
m =3
It seems you double the amount each day. keep doing that until you get to 15
If we let x be the price for soft tacos and y be that of double deckers,
then from the question, we'll have
3x + 3y = 11.25
x + y = 11.25/3
x + y = 3.75 (1)
in addtion, we also have
4x + 2y = 10.00
2x + y = 5.00
y = 5.00 - 2x (2)
<span>Substituting y from equation (2) into equation (1),
x + (5.00 - 2x) = 3.75
-x = 3.75 - 5.00
x = 1.25
y = 5.00 - 2(1.25) = 2.50

Answer:
Lengths to be added are converted into cm.
15 m 18 cm = 1500 cm + 18 cm = 1518 cm
16 m 22 cm = 1600 cm + 22 cm = 1622 cm
Now, sum
1 1
1518 cm
+ 1622 cm
3140 cm
= 31 m 40 cm
Therefore, 15 m 18 cm + 16 m 22 cm = 31 m 40 cm
