Answer:

6 pounds of green candy

Step-by-step explanation:

Let r be the weight of red candy

Let g be the weight of green candy

Total weight = 10 pounds

r + g = 10 -------------------------(I)

Total cost = $ 38.50

2.50r + 4.75g = 38.50  --------------(II)

Multiply equation (I) by -2.50

(I)* (-2.50)             -2.50r - 2.50g = -25.0

(II)                          <u>2.50r + 4.75g = 38.50 </u>   {Now add and r will be eliminated}

                                        2.25g = 13.50

g =13.50/2.25

g = 6

Plug in the value of g in equation (I)

r + 6 = 10

r = 10 - 6

r = 4

Solve 4 + 4 ( x - 2 ) = 2 ( x + 1 ) - x<br> The question requires you to show your work
kati45 [8]

Answer:

x = 2

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 (4+(4•(x-2)))-(2•(x+1)-x)  = 0

Step  2  :

Equation at the end of step  2  :

 (4 +  4 • (x - 2)) -  (x + 2)  = 0

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  3x - 6  =   3 • (x - 2)

Equation at the end of step  4  :

 3 • (x - 2)  = 0

Step  5  :

Equations which are never true :

5.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2      Solve  :    x-2 = 0

Add  2  to both sides of the equation :

                     x = 2

One solution was found :

                  x = 2

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.
OleMash [197]

Answer:

Hello! answer: area is 6 cm2

Step-by-step explanation:

Triangle area formula: base × height ÷ 2 or base × height × 1/2 so...

12 × 16 = 192 192 ÷ 2 = 96

12 ÷ 4 = 3

16 ÷ 4 = 4

3 × 4 = 12 12 ÷ 2 = 6 therefore the area is 6 hope that helps!

A rectangular lawn has an area of 140 square yards. Its width is 6 yards less
Katarina [22]

Answer:

length : 10 yard

width: 14  yard

Step-by-step explanation:

Let l be the length of the yard.

Since the width is 6 yards less than twice its length, we can say the width is 2l-6.

With width x length=area,

l (2l -6) = 140

2l^2 - 6l = 140

2l^2 - 6l - 140 = 0

Using the quadratic formula,

we can determine l = 10 or -7

since the length should not be negative,

the length is 10 yard.

Now substitute l=10 into 2l-6.

width = 2(10)-6

= 14 yard
