Solve for x:
4 - 2(x - 3) = 24
please help
Answer: X = -7
Step-by-step explanation:
Answer:
x = -7
Step-by-step explanation:
4 - 2(x - 3) = 24
Distribute
4 -2x +6 = 24
Combine like terms
10 -2x = 24
Subtract 10 from each side
10-2x-10 = 24-10
-2x = 14
Divide by -2
-2x/-2 = 14/-2
x = -7

The difference of the square of a number and 18 is equal to 3 times that number. Find the positive solution.
Answer:
18 = 3 x 6
Step-by-step explanation:
If you don't know the difference of the square of a number you can already see that it's telling 18 = 3 times that number so identify the missing number by multiplying 3 times a number.
18 = 3 x ?
18 = 3 x 6
18 = 18
:D
Answer:
6
Step-by-step explanation:
Let us start by writing an equation using the variable x.
The square of a number x minus 18 equals 3 times x:
[tex]x^{2} -18=3x[/tex]
Great! Now let us solve for x by moving the 3x term to the left side of the equation and obtain a quadratic equation:
[tex]x^{2} -3x-18=0[/tex]
We can use the quadratic formula [tex]\frac{-b±\sqrt{b^{2}-4ac } }{2a}[/tex] to solve for x. *Please ignore the A after b. I cannot remove it for some reason.*
From our equation, a represents the coefficient of the term with degree of 2. Therefore, our a variable is 1. b represents the coefficient of the term with degree 1. Out variable b is therefore -3. Lastly, c represents the term with degree 0. Our c variable is -18. Lets solve!
[tex]\frac{3 ±\sqrt{(-3)^{2}-4*1*(-18) } }{2*1} =\\\frac{3 ±\sqrt{9+72} }{2} =\\\frac{3 ±\sqrt{81} }{2} =\\\frac{3 ±9}{2} \\\\[/tex]
Now we have two possible solutions. Let us start with the addition version:
[tex]\frac{3+9}{2} =\\\frac{12}{2} =\\6[/tex]
Alternatively you could try the subtraction version:
[tex]\frac{3-9}{2} =\\\frac{-6}{2} =\\-12[/tex]
However, the question asks to find the positive solution. Therefore, out answer is 6.
I hope this helps! Please let me know if you have any questions :)
Which of the following is the explicit rule for a geometric sequence defined by
a recursive formula of…
A. an = 13.7041
OB. a, = 13.70-1
O C. a, = 7.13+1
O D. an = 7.130-1
Answer:
D
Step-by-step explanation:
Always apply the formula a_n=ar^(n-1) in this type of questions, since you know that the first term, a is 7 and the common ratio, r is 13. Therefore you can substitute a = 7 and r = 13 into the equation which equals to a_n=7×13^(n-1)
The explicit rule for a geometric sequence defined by,
a(n) = 7 × 13ⁿ⁻¹
We have to given that,
a (n) = 13 a (n - 1)
Now, We can simplify as,
a (n) / a (n - 1) = 13
a (n) = 13 a (n - 1)
Since, We know that,
a(n) = a × rⁿ⁻¹
Here, a = 7
a(n) = 7 × 13ⁿ⁻¹
Hence, Option c is true.

A restaurant distributed 7,000 coupons. Over the next month, 3,290 of the coupons were redeemed. How many coupons were not used?
Answer:
3,710 coupons
Step-by-step explanation:
You have to do 7,000-3,290 to get the answer, as 7,000 is the total number of coupons given, and 3,290 is the amount of coupons that was used.
7,000-3,290=3,710

Question 17 The numbers in the circles go together in a certain way. Find the missing number marked by the question mark: 180, 14 120, 8 A:70 B: 80 C:60 D: Mr Sockman ?, 4 D:40
Answer:
B. 80
Step-by-step explanation:
According To Question, We Have
(180,14) (120,8) (? , 4) (220,18)
it Clearly Visible That ( 180*a+b=14 ) only Possible when we Put a=1/10 & b=-4. Thus, (180*1/10)-4 ⇔ 18-4 = 14Same For All (120*a+b=8)Thus, (120*1/10)-4 ⇔ 120-4 = 8
Now (?*1/10)-4=4 solve it .
Thus, ?*1/10=8⇔?=80 is Our Missing Number .
Find the circumference of a circle with diameter,
d
= 7.18m.
Give your answer rounded to 2 DP.
Answer:
C = 22.56
Step-by-step explanation:
The equation for the circumference of a circle is [tex]C=2\pi r[/tex].
The radius is half the diameter so [tex]r=\frac{7.18}{2}=3.59[/tex]
Plug the radius into the equation.
[tex]C=2*\pi *3.59[/tex]
[tex]C=22.55664[/tex]
Given:
Diameter of circle = 7.18 m
To find:
Circumference of the circle
Steps:
We know that radius is equal to half of the diameter
r = d/2
r = 7.18/2
r = 3.59 m
Now circumference is equal 2πr
Circumference = 2πr
Circumference = 2 × 3.14 × 3.59 (taking pi as 3.14)
Circumference = 6.28 × 3.59
Circumference = 22.5452
Circumference ≈ 22.55 meters
Therefore, the circumference of the circle is approximately 22.55 meters

Joe works mowing lawns and babysitting. He earns $9.10 an hour for mowing and $7.90 an hour for babysitting. How much will he earn for 1 hour of mowing and 5 hours of babysitting?
Answer:
Joe would receive $9.10 for One hour of mowing the lawn and $39.50 for Five hours of babysitting, which (if needed) adds up to $48.60
Step-by-step explanation:
It's as simple as multiplication. Since he only mowed the lawn for one hour, it would only be $9.10. Since he babysat for 5 hours, you'd simply multiply $7.90 by five, giving you the answer $39.50

let f={(1,2),(2,3),(5,6),(7,8) evaluate f(2)and f(5)?
Given:
[tex]f=\{(1,2),(2,3),(5,6),(7,8)\}[/tex]
To find:
The values of f(2) and f(5).
Solution:
If an ordered pair [tex](x,y)[/tex] is in the function [tex]f[/tex], then [tex]f(x)=y[/tex].
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get
[tex]f(2)=3[/tex]
In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get
[tex]f(5)=6[/tex]
Therefore, the value of f(2) is 3 and the value of f(5) is 6.
