The answer is x=4.5 because 9÷2=4.5 and 4.5×2=9

You need to get x alone so multiply each side by 5 to get rid of the fractions the will get you to 2x=45/15 which equals 2x=3 so x equals 3/2 or 1.5

Answer:

2.41 and 2.50

Step-by-step explanation:

Here, we shall be selecting the correct answer from the option.

a. A is correct

the number we want is between 2.4 and 2.8

2.5 is greater than 2.4 but less than 2.5, this means it meets our criteria

b. 2.41 is also correct

This is because it is greater than 2.4 but less then 2.8

c. wrong

2.4 is same as 2.4, it does not meet the criterion

d. wrong

the value is far lesser than 2.4

: Find the approximate perimeter of the isosceles triangle A OPD.

AleksAgata [21]

Answer:

24.98 units

Step-by-step explanation:

The picture of the question in the attached figure

we have the coordinates

P(1,-6),D(4,3),O(7,-6)

The perimeter of triangle OPD is equal to

$P=OP+PD+OD$

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

step 1

Find the distance OP

we have

O(7,-6),P(1,-6)

substitute in the formula

$d=\sqrt{(-6+6)^{2}+(1-7)^{2}}$

$d=\sqrt{(0)^{2}+(-6)^{2}}$

$d_O_P=6\ units$

step 2

Find the distance PD

we have

P(1,-6),D(4,3)

substitute in the formula

$d=\sqrt{(3+6)^{2}+(4-1)^{2}}$

$d=\sqrt{(9)^{2}+(3)^{2}}$

$d_P_D=\sqrt{90}\ units$

step 3

Find the distance OD

we have

O(7,-6),D(4,3)

substitute in the formula

$d=\sqrt{(3+6)^{2}+(4-7)^{2}}$

$d=\sqrt{(9)^{2}+(-3)^{2}}$

$d_O_D=\sqrt{90}\ units$

step 4

Find the perimeter

$P=6+\sqrt{90}+\sqrt{90}$

$P=6+9.49+9.49=24.98\ units$
