If you have the following equation; 4x - 4.5 = 10.73x + 5.7 + 7x, what would you multiply each term by to get rid of the decimal
posledela

Answer:

100

Step-by-step explanation:

You are given the equation

4x-4.5=10.73+5.7+7x

There are 5 coefficients:

4, \ -4.5,\ 10.73,\ 5.7,\ 7

Two of them are integers

4,\ 7

two of them are decimals with one digit after point

-4.5,\ 5.7

and one is a decimal with two digits after point

10.73

To get rid of fractions, we have to get rid of digits after point. The maximum number of digits after point is 2, then we have to multiply the equation by 100:

400x-450=1,073x+570+700x

An ice cream shop sells sundaes for $2 and banana splits for $3. On a hot day the shop sold 8 more sundaes than banana splits an
lawyer [7]

Answer:

Number of sundaes = 36

Number of banana split = 28

Step-by-step explanation:

On that day, let the number of sundaes sold be x

Now, since they sold 8 more sundaes than banana, the number of bananas sold is x-8

So the cost of sundaes sold will be 2 * x = 2x

the total cost of banana splits sold will be 3(x-8) = 3x -24

The addition of both equals 156

Hence;

2x + 3x-24 = 156

5x -24 = 156

5x = 156 + 24

5x = 180

x = 180/5

x = 36

So

number of sundaes sold is 36 while the number of bananas split sold is 36-8 = 28

The mapping of DEFG to D'E'F'G' is shown. 2 parallelograms have identical side lengths and angle measures. The second parallelog
vodka [1.7K]

Answer:

(A)EF corresponds to E'F'

(C)∠EDG Is-congruent-to ∠E'D'G'

(D)∠DEF Is-congruent-to ∠D'E'F'

(F)The transformation is a rigid transformation.

Step-by-step explanation:

Given:

  • Parallelogram DEFG is mapped to D'E'F'G'
  • DEFG and D'E'F'G' have identical side lengths and angle measures.

The following applies:

  • EF corresponds to E'F'
  • ∠EDG Is-congruent-to ∠E'D'G'
  • ∠DEF Is-congruent-to ∠D'E'F'

Now, a rigid transformation is a transformation of the plane that preserves length. Since the two parallelograms have identical side lengths:

  • The transformation is a rigid transformation.

Note that a reflection is an isometric transformation. Therefore the statement "The transformation is not isometric" is INCORRECT.

FG and GD are adjacent sides, therefore they may not necessarily be congruent. Thus FG does not corresponds to G'D'
