Step-by-step explanation:
Let's solve your equation step-by-step.
s(11−s)=24
Step 1: Simplify both sides of the equation.
−s2+11s=24
Step 2: Subtract 24 from both sides.
−s2+11s−24=24−24
−s2+11s−24=0
Step 3: Factor left side of equation.
(−s+3)(s−8)=0
Step 4: Set factors equal to 0.
−s+3=0 or s−8=0

brian has $45.25 saved and earns $7.25/week. Dakota has $25.25 saved and earns $9.75/week. In how many weeks will they have the same amount?
Explanation pleaseeeeeeee
ASAPPPPPPPPPP!!!!!!!!!!!!!!
Answers
Set up the equation
45.25 + 7.25x = 25.25 + 9.75x
STEP TWO:
Subtract 7.25x from both sides
45.25 = 25.25 + 2.5x
STEP THREE:
Subtract 25.25 from both sides
20 = 2.5x
(Flip equation)
2.5x = 20
STEP FOUR:
Divide 2.5 from both sides
x = 8
Since x represents weeks, it will take 8 weeks for Brian and Dakota to have the same amount of money.
Hope this helped!
They will have same money after 10 weeks.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Brian has $45.25 saved and earns $7.25/week. Dakota has $25.25 saved and earns $9.75/week.
Let the number of weeks be x.
Now, money earned by Brain x weeks is 45.25+7.25x
Money earned by Dakota x weeks is
25.25+9.75x
Now, 45.25+7.25x=25.25+9.75x
2x=20
x=10
Therefore, they will have same money after 10 weeks.

Solve for x then find the meansie if angle a.
Angle A =
Answers
Answer:
[tex]x = 18[/tex]
[tex]\angle A = 166[/tex]
Step-by-step explanation:
The question is properly presented in the attachment.
Given
[tex]\angle A = 7x + 40[/tex]
[tex]\angle B = 3x + 112[/tex]
Required
Solve for x and [tex]\angle A[/tex]
From the attachment [tex]\angle A[/tex] and [tex]\angle B[/tex] are vertically opposite.
This means that:
[tex]\angle A[/tex] = [tex]\angle B[/tex]
Substitute values for [tex]\angle A[/tex] and [tex]\angle B[/tex]
[tex]7x + 40 = 3x + 112[/tex]
Collect Like Terms
[tex]7x -3x = 112 - 40[/tex]

Answer:
2^-2
Step-by-step explanation:
According to the properties of integer exponents, 1/a^n = a^-n.
So 1/2 x 1/2 = 1/2^2 = 2^-2.
1/2 x 1/2 can be rewritten as the exponential expression 2^-2.
Edmentum answer
The expression 1/2 × 1/2 can be written as 2⁻² in the exponential form with the base 2.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 1/2 × 1/2.
We have to write the expression in an exponential form with the base 2.
1/2 × 1/2 = (1/2)²
= 1 / 2²
We have the rule for exponentiation 1 / aᵇ = a⁻ᵇ
1/2 × 1/2 = 2⁻²
Hence the exponential form of the given expression with the base 2 is 2⁻².

The solution to the inequality 18≥5K+4K is K ≤ 2.
To solve the inequality 18 ≥ 5K + 4K, we can combine the like terms on the right-hand side and simplify:
18 ≥ 5K + 4K
Combining the like terms:
18 ≥ 9K
We want to isolate the variable K on one side of the inequality.
Divide both sides of the inequality by 9:
(18/9) ≥ (9K/9)
2 ≥ K
Therefore, the solution to the inequality is K ≤ 2.

The equation below can be used to find the length of a foot or forearm when you know one or the other.
(length of the foot) = 0.860 • (length of the forearm) + 3.302
If you let y = length of the foot and x = length of the forearm, this equation can be simplified to
y = 0.860x + 3.302.
Using this equation, how long would the foot of a person be if his forearm was 17 inches long?
