I’m the figure below, g II j. Find the values of z and x.

9514 1404 393

Answer:

Step-by-step explanation:

Let x, y, z represent the numbers of cheeseburgers, plain burgers, and chicken burgers ordered for the party.

We have three relations given. Each can be used to write an equation.

  x + y + z = 500 . . . . . . . . . a total of 500 meals were ordered

  2.50x +1.75y +3.20z = 1172.50 . . . . . the total cost

  0x +y -z = 100  . . . . . . . . . . 100 fewer chicken were ordered than plain

_____

Additional comment

We put the coefficient of x as 0 in the last equation to facilitate writing this system as an augmented matrix.

  [tex]\left[\begin{array}{ccc|c}1&1&1&500\\2.50&1.75&3.20&1172.50\\0&1&-1&100\end{array}\right][/tex]

The solution is (x, y, z) = (300, 150, 50).

DeShawn pays .67 cent per pound of sugar

Step-by-step explanation:

[tex]\tt{} \frac{3}{4} (x - 6) = 2(x - 3) + 4[/tex]

[tex]\tt{} \frac{3}{4} x - \frac{9}{2} = 2x - 6 + 4[/tex]

[tex]\tt{} \frac{3}{4} x - \frac{9}{2} = 2x - 2[/tex]

[tex]\tt{}3x - 18 = 8x - 8[/tex]

[tex]\tt{}3x - 18 = - 8 + 18[/tex]

[tex]\tt{} - 5x = 10[/tex]

[tex]\tt{}x = - 2 \\ \\ [/tex]

Answer:

x=-8

Step-by-step explanation:

3/4( x -16) = 2 ( x- 3) +4

3/4x - 3/4*16 = 2x - 6 + 4

3/4 x -12 =2x -2

-2x = -2x

________________

-5x/4 -12 = -2

+2 = +2

_____________

-5x/4 = 10

x=- 10*4/5

x= -8

Answer:

The answer is 190.5cm

Step-by-step explanation:

o solve this problem, we first need to convert marco's height to inches.

there are 12 inches in 1 foot.

multiply.

notice how ft cancel out because they are in opposite positions of the fraction.

add 72+3 to get marco's height in inches.

marco is 75inches.

with this information, we can solve for his height in cm.

write an equation.

solve.

marco is 190.5centimeters

[tex]Q.1)\:x=20[/tex]

[tex]Q.2)c=-4.7[/tex]

Step-by-step explanation:

[tex]Q1)[/tex] [tex]7\left(x+5\right)-6x=55[/tex]

Use the distributive property to multiply 7 by x+5 :

[tex]x+35=55[/tex]

Subtract 35 from both sides:

[tex]x+35-35=55-35[/tex]

[tex]x=20[/tex]

___________________________

[tex]Q2)[/tex] [tex]c-1.5+6.8=0.6[/tex]

[tex]-1.5+6.8=5.3[/tex]

[tex]c+5.3=0.6[/tex]

Subtract 5.3 from both sides:

[tex]c+5.3-5.3=0.6-5.3[/tex]

[tex]c=-4.7[/tex]

Answer:

z≥−3

Step-by-step explanation:

1 Subtract 88 from both sides.

5z≥−7−8

2 Simplify  -7-8−7−8  to  -15−15.

5z≥−15

3 Divide both sides by 55.  

z≥− 15/5

4 Simplify 15/5 to 3

z≥−3

Step-by-step explanation:

Hello there! :)

We are given that these figures are similar.

It means that the sides are proportional. So

[tex]\frac{4}{6} =\frac{6}{x}[/tex]

Cross-multiply:

4x=36

Divide both sides by 4 to isolate x:

x=9 cm

Answer:

Let x = the measure of the smaller angle

Let 3x + 40 = the measure of the larger angle

x + 3x + 40 = 180

4x = 140

x = 35º

3x + 40 = 3(35) + 40 = 145º
