Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
x and 65° are a linear pair and sum to 180°
x + 65° = 180° ( subtract 65° from both sides )
x = 115°
y and 65° are vertically opposite angles and are congruent , then
y = 65°
x and z are vertically opposite angles and are congruent , then
z = x = 115°
Answer:
Washing Powder
Step-by-step explanation:
Cost less and cleans better.
Store A is cheaper than B
The way to solve is pretty simple for B.
You have to divide the cost by the number of tubes.
So in this case:
9/3=3
15/5=3
21/7=3
See the pattern?
So the cost per lip gloss is $3.
Now for Store A:
Just divide 5.50/2
The answer is 2.75
Compare both numbers
2.75<3.00
So, store A is cheaper.
