10x+9=4x -9 solve <br><br> please help

Neporo4naja [7]

Answer:

x = -3

Step-by-step explanation:

To solve this, you need to isolate the variable x, this means only one side of the equation should have the variable x. To do this, you need to do the opposite operation from what's given (if it's addition, use subraction; if it's multiplication, use division; these work vise versa)

Subtract 9 from both sides of the equation. This gives you 10x = 4x - 18.
Subtract 4x from both sides of the equation. This gives you 6x = -18.
Divide both sides by 6. This gives you x = -3

The final answer is x = -3

The length of a living room is 12 feet and its width is 1012 feet. The length of the room is being expanded by x feet. Choose an

Ivanshal [37]

Answer:

Option C. 10.5(12 + x) square feet

Option E. (126 + 10.5x) square feet

Step-by-step explanation:

step 1

Find the area of the original living room

we know that

The area of the original living room is equal to

$A=LW$

we have

$L=12\ ft\\W=10\frac{1}{2}\ ft=10.5\ ft$

substitute

$A=(12)(10.5)=126\ ft^2$

step 2

Find the new area of the living room

The length of the room is being expanded by x feet

so

we have

$L=(12+x)\ ft\\W=10.5\ ft$

The new area is

$A=10.5(12+x)\ ft^2$

The expanded form of the expression is

Apply distributive property

$A=10.5(12)+10.5(x)\\A=(126+10.5x)\ ft^2$

Suppose the number of children in a household has a binomial distribution with parameters n-8 and p-50%. Find the probability of

Goshia [24]

Answer:

Step-by-step explanation:

Given that the number of children in a household has a binomial distribution with parameters n-8 and p-50%

As per binomial definition we have

$P(X=r) = nCr p^r q^{n-r}$

= $8Cr (0.5)^r (0.5)^{n-r} \\=8Cr(0.5)^8$

a) P(x=3 or 7) = P(3)+P(7) = 0.2188+0.0313=0.2501

b) P(X≤5)=0.8555

c) P(X≥3)=0.8555

d) P(x<7) =0.9648

A lawn-mowing company is trying to grow its business. It had 26 clients when they started its business and wants to increase by

Likurg_2 [28]

Answer:

B. f(x) = 3x + 26;26≤ y ≤ 35

Step-by-step explanation:

This would be a linear equation in the form

y= mx+b

where b is the initial value (or 26 clients)

m is the slope, or the amount they want to increase by each week

y = 3x+26

Let x =0

y = 26 or what we start with

Let x =3, or be week 4 (we started with x= 0)

y = 3*3 +26

y =9+26

y= 35
