20×+4=4(5x+1) how many solution are in this equation

Mathematics
1 answer:
Tomtit [17]4 years ago
7 0

Simplify both sides of the equation

(20)(4)= 4(5x+1)

Simplify

80 = 20x+4

Flip the equation

20x+4 = 80

Subtract 4 from both sides

20x+4-4 = 80-4

20x = 76

Divide both sides by 20

20x/20 = 76/20

x= 3.8


There is one solution in this equation

Khalil has a game board as shown below, which is a square with 20 cm sides. The area of the largest circle is 314
Elenna [48]

Answer:

The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board

step 1:

Find the area of the square game board

"A=b^{2}"

we have

b=20cm

"substitute"

A=20^{2}

=400cm²

step 2:

Find the probability

P=314/400

=0.785

=0.785 x 100

=78.5%

How many plastic cubes can fit into the box?
netineya [11]

Option D:

160 plastic cubes can fit into the box.

Solution:

Convert mixed fraction into improper fraction.

Length of the box = 4 ft

Width of the box = 2\frac{1}{2}=\frac{5}{2} ft

Height of the box = 2 ft

Volume of the box = length × width × height

                                 $=4\times\frac{5}{2} \times2

                                 = 20 ft³

Volume of the box = 20 ft³

Length of the plastic cube = \frac{1}{2} ft

Volume of the cube = length × length × length

                                 $=\frac{1}{2} \times\frac{1}{2} \times\frac{1}{2}

                                 $=\frac{1}{8} \ \text{ft}^3

Volume of the cube = 0.125 ft³

$\text{Number of plastic cubes}=\frac{\text{Volume of box}}{\text{Volume of cube}}      

                                        $=\frac{20}{0.125}

                                        = 160

Number of plastic cubes = 160

Hence 160 plastic cubes can fit into the box.

Option D is the correct answer.
