Kayla buys two pairs of jeans for j dollars each and one shirt for 15 dollars. The cost of one pair of jeans is $22.5 (twenty-two dollars and fifty cents)
From the given information
- Let the cost of two pairs of jeans be 2j
- The cost of 1 shirt = 15
- Total amount to spent = $60
∴
The equation is said to be expressed as:
Collect like terms
Divide both sides by 2
- j = 22.5
Therefore, we can conclude that the cost of one pair of jeans is $22.5 (twenty-two dollars and fifty cents).

Answer:
mDF = 90°
(Assuming arc mCE is 5x + 10)
Step-by-step explanation:
When we have two chords crossing in a circle, there is a property where the angle in the cross point is equal half the sum of the corresponding arcs.
So in this case, we have:
70° = (mCE + mDF)/2
Assuming mCE is 5x + 10, we have:
70 = (5x + 10 + 11x + 2)/2
70 = (16x + 12)/2
70 = 8x + 6
8x = 64
x = 8
So the arc mDF is:
mDF = 11x + 2 = 11 * 8 + 2 = 90°
Answer:
w = 60
Step-by-step explanation:
the midsegment SU is half the measure of side RV , then
SU = 
RV , so
w - 30 = w ( multiply through by 2 to clear the fraction )
2w - 60 = w ( subtract w from both sides )
w - 60 = 0 ( add 60 to both sides )
w = 60
