8) X= -1

Divide both sides by 12, move the constant to the right, and subtract

9) X= 31.5

Multiply both sides by 7, reduce and multiply

10) X= 12
11) X= -12
12) y= 3/2
13) y= 2/3 I believe if the cropped out number is 6

Hope this helps:)

Step-by-step explanation:

8, 12(3-x)=48

36-12x=48

-12x=48-36

-12x=12 both side divideos by -12

-12x/-12=12/-12

x= 1

9, x/7=4.5 cris cross

x=31.5

10,5(x-3)=45

5x-15=45

5x=45+15

5x=60 both side divided by 5

5x/5=60/5

x=12

11,-3(x-3)=45

-3x+3=45

-3x=45-3

-3x=42 both side divided by -3

-3x/-3=42/-3

x=14

12,14y-8=13

14y=13+8

14y=21 both side divided by 14

14y/14=21/14

y=1.5

13,3m=5m-8/5

3m-5m=-8/5

-2m=-8/5 cris cross

-10m=-8 both side divided by -10

-10m/-10=-8/-10

x=0.8

15s^11-25s^4 factorised plz tell me. :)

saveliy_v [14]

For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have

$5(3s^{11}-5s^4)$

As for the literal part, you can factor $s^4$ because it's the power of s with the smallest denominator. So, we have

$5s^4(3s^7-5)$

Answer:

the answer is 35 over 102 or 35/102

Step-by-step explanation:

so first we turn that 1 and 1/5 into 6/5 and then we flip the numbers into 5/6. so now we multiply 7/17 x 5/6 = 35/102. The Number can not be reduced.

Nancy found that x=1 is one solution to the quadratic equation (x 2)2=a. what is the value of a? -9 -3 3 9

AlladinOne [14]

The value of the a, in the provided quadratic equation for which Nancy found one solution as x=1 is 9.

<h3>What is the solution of equation?</h3>

The solution of the quadratic equation is the solution of the variable of the equation, for which the equation satisfies.

Nancy found that x=1 is one solution to the quadratic equation. The quadratic equation is,

$(x +2)^2=a$

For this equation, one solution is x=1. Put this value in the above equation to get the value of a,

$(1 +2)^2=a\\(3)^2=a\\9=a\\a=9$

Thus, the value of the a, in the provided quadratic equation for which Nancy found one solution as x=1 is 9.
