-2(a-8)+6a=36 what's the value of a A=

ivann1987 [24]

Distribute -1 into the brackets.
-2(a - 8) + 6a = 36
-2a + 16 + 6a = 36
Take 16 to the other side
-2a + 6a + 16 = 36
- 16 -16
-2a + 6a = 36 - 16
Combine like terms
4a = 20
Divide by 4 on either sides to isolate a
$\frac{4a}{4} = \frac{20}{4}$
4 and 4 cancels out.
a = 5

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.

Answer:

x = 12

y = 4√10

z = 12√10

Step-by-step explanation:

The geometric mean rules apply. Each of the segments labeled with a letter is the geometric mean of the segments it touches on the hypotenuse.

x = √(4×36) = 12

y = √(4×(4+36)) = 4√10

z = √(36×(36+4)) = 12√10
