How do you solve 26/57= 849/5x

sergeinik [125]

If you would like to solve 26/57 = 849/5x, you can do this using the following steps:

26/57 = 849/5x /*(5x)
26/57 * (5x) = 849 /*57
26 * 5x = 849 * 57 /26
5x = 48393/26 /5
x = 48393/(26*5)
x = 372.25

The correct result would be 372.25.

Mr.Nelson bought a coat on sale for $27 less than third its original price . He paid $54. What was the original price?

MAVERICK [17]

Answer:

$243.

Step-by-step explanation:

We can use algebra here.

Let x = the original price.

Then 1/3 x - 27 = 54

1/3x = 54 + 27 = 81

x = 81 / 1/3

x = 81 * 3

x = $243 (answer).

Given each of the following areas, what would be the radius of each circle? a. A = 530.66 m2 b. A = 907.46 sq. ft. c. A = 379.94

ra1l [238]

Area for a circle is $A= \pi r^2$ . We will fill in each area and then solve for the radius. $530.66m^2= \pi r^2$ and $\frac{530.66m^2}{3.14}=r^2$ . ∴ $169=r^2$ and r = 13. For b, $907.46ft^2= \pi r^2$ and $\frac{907.46ft^2}{3.14}=r^2$ . $289=r^2$ , ∴ r = 17. For c, $379.94mi^2= \pi r^2$ , and $\frac{379.94mi^2}{3.14}=r^2$ . ∴, $121=r^2$ and r = 11. For d, $1962.5cm^2= \pi r^2$ , and $\frac{1962.5cm^2}{3.14}=r^2$ . ∴, $625=r^2$ so r = 25. And there you have it!
