first subtract the last equation from the first. this gives:-

-x + y = -8 .....................(1)

Then multiply the first equation by 2 and add it to the 2nd equations This gives

9x = 18  

so x = 2

and from equation  (1)  y = -8 + 2 = -6

Substituting for x and y in the second equation

z =  (24 -5(2) -12) / 2 =   1


Answer is choice b.

Ray UW is the angle bisector of Angle VUT. If the measure of Angle VUW = (4x + 6)° and the measure of Angle WUT = (6x – 10)°, wh
Lunna [17]

Hello! :)

Answer:

\huge\boxed{38^{\circ}}

--------------------------------------------------------------------------

An angle bisector divides an angle in half, therefore:

m∠VUW ≅ m∠WUT

Set the expressions equal to each other:

4x + 6 = 6x - 10

Subtract 4x from both sides:

6 = 2x - 10

Add 10 to both sides:

16 = 2x

Divide 2 from both sides:

x = 8.

Substitute in the value of "x" into the equation for ∠WUT:

6(8) - 10 = 48 - 10 = 38°.

The population of a pack of wolves is 88. The population is expected to grow at a rate of 2.5% each year.
Dennis_Churaev [7]

Answer:

Option B is correct.

f(t) = 88(1.025)^t represents the population of the pack of wolves after t years

Step-by-step explanation:

The exponential growth function is given by;

f(t) = a(1+r)^t               ......[1]

where

a represented the initial value

r represents the rate(in decimal)

t represents the time in years

As per the given statement: The population of a pack of wolves is 88. Also, the population is expected to grow at a rate of 2.5% each year.

⇒ a = 88 and  r =2.5% = 0.025.

Substituting these values in equation [1], we have;

f(t) = 88(1+0.025)^t

or

f(t) = 88(1.025)^t

Therefore, the population model of the pack of wolves after t years is given by:  f(t) = 88(1.025)^t

Julio is paid 1.4 times his normal hourly rate for each hour he works over 30 hours in a week.last week he worked 35 hours and e
blagie [28]

For 30 hours Julio is paid 30r dollars.

For the extra 5 hours he worked he earns 5*1.4r = 7r dollars

So the equation is

30r + 7r = 436.60

37r = 436.60

r = 436.60 / 37 = 11.80

His normal hourly rate is $11.80 answer
