1-3(x-5)=5x-12/2 <br><br><br>solve this equation

7nadin3 [17]

Answer:

x= 1/3

Step-by-step explanation:

simplify so you can isolate x quicker: 2x-5=5x-6

subtract 2x from both sides: -5=3x-6

add 6 to both sides: 1=3x

divide both side by the 3 to isolate x: 1/3=x

A salesperson's weekly paycheck is 40% more than a second salesperson's paycheck. The two paychecks total $1075. Find the amount

BlackZzzverrR [31]

X is gonna be the normal paycheck

0.45x+x=1075

= 0.40x+x=1075

= 1.4x=1075

x= 1075/1.4

x=767.85 the normal paycheck price

1075.00-767.85= 307.15

so a saleperson weekly paycheck is 307.15 dollars more

hope this helps

a quadratic equation has a discriminant of 12. which could be the equation? a.0 = –x2 8x 2 b.0 = 2x2 6x 3 c.0 = –x2 4x 1 d.0 = 4

Norma-Jean [14]

Answer:

Option b which is $2x^2+6x+3=0$

Step-by-step explanation:

We have been given the discriminant 12

We have to choose the equation which will satisfy the given discriminant.

We will consider all the given equation one by one

First we will take option a which is $-x^2+8x+2=0$

Discriminant from the equation we will find by the formula

$D=b^2-4ac$

Here, a=-1,b=8 and c=2 on substituting the values we will get

$D=8^2-4(-1)(2)=72$

Hence, option a is incorrect.

Now, we will consider option b which is $2x^2+6x+3=0$

Here, a=2,b=6 and c=3 on substituting the values we get

$D=(6)^2-4(2)(3)=12$

Hence, option b is correct

Therefore, option b is the required answer.

Find: m∠1, m∠2, and m∠5 in degrees

gulaghasi [49]

Answer:

<1 = 100

<2 = 80

Step-by-step explanation:

Angle 1 and angle 2 are supplementary

Supplementary angles add to 180 degrees

<1 + <2 = 180

The angles are in a ratio of 5 to 4

Multiply by x to get the measure of each angle

<1 = 5x <2 = 4x

5x+4x = 180

Combine like terms

9x = 180

Divide by 9

9x/9 =180/9

x =20

<1 = 5x = 5*20 = 100

<2 = 4x = 4*20 = 80
