Ray UW is the angle bisector of AngleVUT.
tester [92]

Answer:

AngleWUT =38°, option 2

Step-by-step explanation:

We have three rays passing through U. A ray is set extend in one direction with one fixed point.

We have UW ray bisecting VUT.As the ray bisects the angle between VUW and WUT would be same .

Given angles are (4x+6)° and (6x-10)°.

As these angles are equal

4x+6=6x-10

2x=16

x=8

AngleWUT = (6x – 10)°

and x is 8 so on substituting AngleWUT =38°.

Chloe purchased some dried mango and dried kiwi to make some trail mix. The dried mango cost ​$2.11 per pound and the dried kiwi
andreev551 [17]

Answer:

Number of pounds of dried mangoes Chloe bought = 3.5

Number of pounds of dried kiwi Chloe bought bough = 6.5

Step-by-step explanation:

Total number of pounds of dried fruit purchased = 10

Let number of pounds of dried mango purchased = x

Let number of pounds of dried kiwi purchased be = y

Total weight of dried fruits purchased = x+y

So, we have a sum equation as:

x+y=10

Total cost of dried fruits = $40.34

Cost of a pound of dried mango = $2.11

Cost of x pounds of dried mango in dollars can be given as = 2.11x

Cost of a dried kiwi = $5.07

Cost of y pounds of dried kiwi in dollars can be given as = 5.07y

Total cost of dried fruits in dollars = 2.11x+5.07y

So, we have a cost equation as:

2.11x+5.07y=40.34

The system of equations is :

A) x+y=10

B) 2.11x+5.07y=40.34

Solving by substitution.

Rearranging equation A, to solve for y in terms of x

Subtracting both sides by x

x+y-x=10-x

y=10-x

Substituting value of y we got from A into equation B.

2.11x+5.07(10-x)=40.34

Using distribution.

2.11x+50.7-5.07x=40.34

Simplifying.

-2.96x+50.7=40.34

Subtracting both sides by 50.7.

-2.96x+50.7-50.7=40.34-50.7

-2.96x=-10.36

Dividing both sides by -2.96.

\frac{-2.96x}{-2.96}=\frac{-10.36}{-2.96}

∴ x=3.5

We can plugin x=3.5 in the rearranged equation A to get value of y

y=10-3.5

∴ y=6.5

So, number of pounds of dried mangoes Chloe bought = 3.5

Number of pounds of dried kiwi Chloe bought bough = 6.5
