Answer:

C. x = 6.0

Step-by-step explanation:

If you use the Pythagorean Theorem, you'll see that x^2 + 5^2 = 8^2. That'll simplify down to

x^2 + 25 = 64. Then you subtract 25 from 64 and that'll give you 39. You then have to find what √39 is and that is 6.244, so that is 6.0 simplified to the nearest tenth.

Solve for x 26=3x+2x-9

umka2103 [35]

Combine like terms on the right side:

$3x + 2x = 5x$
$26 = 5x - 9$

Add 9 to both sides:

$35 = 5x$

Divide both sides by 5 to get x by itself:

$x = 7$

The value of x is 7.

Please help... How many odd perfect squares are between 5 and 211?

frez [133]

Answer:

we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Step-by-step explanation:

Let us check by taking squares

3² = 9

5² = 25

7² = 49

9² = 81

11² = 121

13² = 169

As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.

Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Elaina ran 2.52 miles on Monday, 4.53 miles on Wednesday, and 3.45 miles on Saturday. What percent of the total miles did Elaina

Aleks04 [339]

Add all the miles
2.52+4.53+3.45=10.5 miles

(Monday/total miles)*100%
=(2.52/10.2)= 24%
