Answer:
see explanation
Step-by-step explanation:
x + y = 90 → (1) ( complementary angles )
x + z = 180 → (2) ( supplementary angles ) and
z = 3x - 8 ( 8 less than 3 times x ), substituting in (2)
x + 3x - 8 = 180
4x - 8 = 180 ( add 8 to both sides )
4x = 188 ( divide both sides by 4 )
x = 47
Substitute x = 47 into (1)
47 + y = 90 ( subtract 47 from both sides )
y = 43
and z = 3x - 8 = 3(47) - 8 = 141 - 8 = 133
Thus
x = 47°, y = 43° and z = 133°

Answer:
x = 57.2
Step-by-step explanation:
Equation:
32.8 + x = 90
x = 90 - 32.8
x = 57.2
Answer:
4x <= 20
x <= 5
A single cupcake can cost at most $5.
Step-by-step explanation:
Let the price of a single cupcake be x.
We know that there are 4 cupcakes in a box, so 4x is equal to the price of 4 cupcakes and hence the price of a box.
The question tells us that a box costs at most $20, so we can write this as an inequality:
4x <= 20
Divide both sides by 4 to isolate and solve for x:
x <= 5
x is less than or equal to 5, which can be interpreted as a cupcake costing at most $5.
