Answer:
s=6
Step-by-step explanation:
Answer:
s = 6
Step-by-step explanation:
Given: -2s + 8(9 - s) = 3 - (9 - 3s)
Get rid of the brackets by using the distributive property:
-2s + 72 - 8s = 3 - 9 + 3s
You can rearrange the items so the expression is easier to solve:
-2s - 8s + 72 = 3s + 3 - 9
Combine like terms:
-10s + 72 = 3s - 6
Now let's subtract 72 from both sides of the expression:
-10s = 3s - 78
Next, subtract 3s from both sides of the expression:
-13s = -78
Lastly, divide each side of the expression by -13 to get:
s = 6

Given the information below, find AC. B is between A and C AC=2x+8 AB=4x-16 BC=3x-6
Answers
Answer:
[tex]AC = 20[/tex]
Step-by-step explanation:
Given
[tex]AC = 2x + 8[/tex]
[tex]AB = 4x - 16[/tex]
[tex]BC = 3x - 6[/tex]
Required
Find AC
First, we need to solve for x
Since B is between A and C, then
[tex]AC = AB + BC[/tex]
Substitute values for AC, AB and BC
[tex]2x + 8 = 4x - 16 + 3x - 6[/tex]
Collect Like Terms
[tex]2x - 4x - 3x = -16 - 6 - 8[/tex]
[tex]-5x = -30[/tex]
Divide through by -5
[tex]\frac{-5x}{-5} = \frac{-30}{-5}[/tex]
[tex]x = \frac{-30}{-5}[/tex]
[tex]x = 6[/tex]
Substitute 6 for x in [tex]AC = 2x + 8[/tex]
[tex]AC= 2 * 6 + 8[/tex]
[tex]AC= 12 + 8[/tex]
[tex]AC = 20[/tex]

p(2)=_____
The value ____ is a root of p(x).
Answers
Answer: p(-2)= 0
P(2)= -16
The value of -2 is a root of p(x).
Step-by-step explanation:
Step-by-step explanation:
By the remainder theorem, the value 2 is a root of P(x) because P(2) = 0
What are the roots of a function?The roots of a function are the zeros of the function
The equation of the function is given as:
[tex]P(x)= \sqrt{2-x}[/tex]
Calculate P(2) and P(-2)
[tex]P(2)= \sqrt{2-2} = 0[/tex]
[tex]P(-2)= \sqrt{2-(-2)} = 2[/tex]
Since P(2) = 0, then the value 2 is a root of P(x)

Rita drove 320 miles using 12 gallons of gas. At this rate, how many gallons of gas would she need to drive 296 miles?
Answers
Answer:
11.1 gallons
Step-by-step explanation:
So, Abdul drove 320 MILES using 12 GALLONS, how many gallons will he need to drive 296 MILES. This can be represented mathematically by;
320 miles=12 gallons
296 miles=x
I replaced the unknown value with the letter x to make it easier to identify. Anyway, you need to cross and multiply. So 296 will multiply 12 and 320 will multiply x.
296 multiplied by 12 is 3552 and 320 multiplied by x is 320x. So;
3552=320x
Divide the both sides by 320 to reveal the value of x. 320 divided by 320 is x. And 3552 divided by 320 is 11.1. So;
x=11.1 gallons of gas
Answer:
11.1
Step-by-step explanation:
CROSS multiple
320/ 12 = 296 / x
x= 11.1

Answers

x = -2.6875
Step-by-step explanation:
Answer:
-3.5
Step-by-step explanation:
First, simplify both sides of the equation.
−6.1+0.4x+1.2=−6.3
(0.4x)+(−6.1+1.2)=−6.3 (Combine Like Terms)
0.4x+−4.9=−6.3
0.4x−4.9=−6.3
Then add 4.9 to both sides.
0.4x−4.9+4.9=−6.3+4.9
0.4x=−1.4
Then divide both sides by 0.4.
0.4x/0.4 = −1.4/0.4
x = −3.5

so confuuuuuused HALP PLEASE
Answers
I hope that it will be help full to u
Step-by-step explanation:As we know point slope form ,
(Y- Y1) = m (X- X1)
As given data ,
m =4/3
(X1,Y1) = (-2, 11)
X1=-2 , Y1= 11
putt in the above equation these values, we get
Y-11 = (4/3) ( X-(-2))
Y-11 = (4/3)X +8/3
Y= (4/3)X +8/3+11

What is the length of the sides of kite ABCD? Find the lengths of side AB and side CD. AB = 20; CD = 15 AB = 15; CD = 20 AB = 9; CD = 16 AB = 24; CD = 25
Answers
Answer:
AB = 15; CD = 20
Step-by-step explanation:
The question is attached.
A kite is a quadrilateral (four sides) with two pairs of equal sides which are adjacent to each other. A kite has two diagonals and the longer diagonal bisects the shorter diagonal.
We can use Pythagoras theorem to find the length of the kite sides:
AB² = 12² + 9²
AB² = 225
Taking square root of both sides:
AB = 15
AB = BC = 15 (adjacent sides of a kite are equal)
CD² = 12² + 16²
CD² = 400
Taking square root of both sides:
CD = 20
CD = AD = 20 (adjacent sides of a kite are equal)
