Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or
belka [17]

Answer:

z = 29°

Step-by-step explanation:

We know that the 3 angles in a triangle always add up to 180°.  So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).  

angle A + angle B + angle C = 180°

59° + 92° + z = 180°

151° + z = 180°

Subtract 151° from both sides of the equation

z = 180° -151°

z = 29°

Does the following equation have one solution, infinite solutions, or no solution? 2(x-1) +3 = 2x + 1
polet [3.4K]

Answer:

Infinite solutions

Step-by-step explanation:

(x−1)+3=2x+1

(2)(x)+(2)(−1)+3=2x+1(Distribute)

2x+−2+3=2x+1

(2x)+(−2+3)=2x+1(Combine Like Terms)

2x+1=2x+1

2x+1=2x+1

Step 2: Subtract 2x from both sides.

2x+1−2x=2x+1−2x

1=1

Step 3: Subtract 1 from both sides.

1−1=1−1

0=0

Write an equation which represents c, the total cost of n pizzas purchased.
bezimeni [28]
C= total $ cost
n= number of pizzas purchased
x= $ cost per pizza

C= x * n
C= xn

If you know the cost per pizza and the number of pizzas purchased, plug those numbers in the equation above to find the total cost.

EXAMPLE: If each pizza cost $10 and 5 were purchased, the equation would be: C= ($10)(5)= $50 total

ANSWER: C= xn

Hope this helps! :)

Solve the system.
Alex777 [14]

Answer:

{x,y,z} = {-18,4,2}

Step-by-step explanation:

Solve equation [2] for the variable  x  

x = -10y + 2z + 18

Plug this in for variable  x  in equation [1]

(-10y+2z+18) + 9y + z = 20

- y + 3z = 2

Plug this in for variable  x  in equation [3]

 3•(-10y+2z+18) + 27y + 2z = 58

   - 3y + 8z = 4

Solve equation [1] for the variable  y  

 y = 3z - 2

Plug this in for variable  y  in equation [3]

  - 3•(3z-2) + 8z = 4

   - z = -2

Solve equation [3] for the variable  z  

 z = 2

By now we know this much :

 x = -10y+2z+18

   y = 3z-2

   z = 2

Use the  z  value to solve for  y  

 y = 3(2)-2 = 4

Use the  y  and  z  values to solve for  x  

 x = -10(4)+2(2)+18 = -18
