I need help on this!!!!! PLEASE!!!!!!​

Answer:

x=28

Step-by-step explanation:

-2(3x-9)+5x =-10

now we times -2 to to the inside of the parenthese

giving us

-6x+18 +5x= -10

add like terms

add -6x and 5x

-1x+18=-10

now we add like terms of the constants

minus 18 on  both sides

-1x=-28

now divide by -1

x = 28

Answer:

x = 28

Step-by-step explanation:

First, remove the parentheses by distributing -2.

-6x + 18 + 5x = 10

Next, collect the like terms.

-x + 18 = -10

Next, move the constant to the right-hand side and change its sign.

-x = -10 - 18

Next, calculate the difference

-x = -28

Lastly, change the signs on both sides of the equation.

x = 28

These are the steps to answer this equation.

Answer:

X = -5

Step-by-step explanation:

3x - 15 = -30       You want to isolate tha variable

3x= -30+15    Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30

3x= -15    

x= -15÷3   Divide x by 3 in order to get rid of the 3. Do it to the other side

x=-5  

Answer:

Step-by-step explanation:

Step one.

Read the slope

-1/4

Step two

Put the slope in the general equation

y = mx + b

y = -1/4 x + b

Step 3

Put the point into the equation from step 2

(-8,5)

5 = -1/4  -8   + b

5 = 2 + b                   Subtract 2 from both sides

5-2 = b

b = 3

Step 4

Write the entire equation

y =   -1/4 x + 3

Answer:

Subtract 3.6 from both sides.

Step-by-step explanation:

Given

[tex]x + 3.6 = -1.7[/tex]

Required

Solve in one step

There are two ways to go about it.

1. Collect Like Terms

[tex]x + 3.6 = -1.7[/tex]

3.6 and -1.7 are like terms, so the equation becomes

[tex]x = -1.7 - 3.6[/tex]

[tex]x = -5.3[/tex]

2. Subtract 3.6 from both sides

[tex]x + 3.6 = -1.7[/tex]

This becomes

[tex]x + 3.6 - 3.6 = -1.7 - 3.6[/tex]

[tex]x = -5.3[/tex]

Hence, the last option answers the question.

Answer:

Option 2and 5 are correct.

Step-by-step explanation:

-Add -3.6 to both sides

-Subtract 3.6 from both sides

Answer:

PB = 1.8

Step-by-step explanation:

PQ = 8 cm, BC = 10 cm and AB = 9 cm

∆ABC is similar to ∆APQ.

Therefore:

[tex] \frac{AB}{AP} = \frac{BC}{PQ} [/tex]

Plug in the values

[tex] \frac{9}{AP} = \frac{10}{8} [/tex]

Cross multiply

AP × 10 = 8 × 9

AP × 10 = 72

Divide both sides by 10

AP = 7.2

PB = AB - AP

PB = 9 - 7.2

PB = 1.8
