solve the rational equation: 7 - 2/x = 4 + 10/x
Answer:
7 - 2 / x = 4 + 10 / x
or , 7 - 4 = 10 / x + 2 / x
or , 3 = 12 / x
or , x = 12 / 3
Therefore , x = 4

2(7)=14+4=18
you multiply the 2 and 7 and then add the 4
Answer:
18
Step-by-step explanation:
what this wants you do do is use PEMDAS. the number in parentheses always means to multiply. first youre gonna multiply 2 by 7 which gives you fourteen. then add 4 to 14 which gives you 18.

4xy = 88. If y = 2, then what is x?
Answer: x = 11
Step-by-step explanation:
first, i did simple calculations.
4x(2) = 88
that calculates out to:
8x = 88
then, i divided both sides by 8, in order to get x by itself.
8x/8 = 88/8
x = 11

Need help with explicit rule. Please help.
Answer:
An = 74(1.07)^n-1
Step-by-step explanation:
Here, we want to get the explicit rule
We are told that the sequence is geometric
At hour 4, we have that this is the 4th term
With conformance to the rule of geometric progression;
T4 = ar^3
90 = ar^3
for the 6th hour, this is the sixth term
103 = ar^5
dividing the 6th term by the 4th term, we have that
103/90 = ar^5/ar^3
103/90 = r^2
r = 1.07
To get a, we simply use any of the terms to substitute
using;
ar^3 = 90
a = 90/r^3
a = 90/1.07^3
a = 73.5 which is approximately 74
So the explicit rule is as follows;
An = 74(1.07)^n-1

How do I do this? Please give subtle explanation too. I don't really understand at all. If I understand this question, I'll understand the rest.
(it's 54 points too lol)
Step-by-step explanation:
An = -2 * An-1
What this means is that you multiply -2 to the term to get the next term.
Since our 1st term (A1) is -2, we have:
A2 = -2 * A1 = -2 * (-2) = 4,
A3 = -2 * A2 = -2 * (4) = -8,
A4 = -2 * A3 = -2 * (-8) = 16,
A5 = -2 * A4 = -2 * (16) = -32,
A6 = -2 * A5 = -2 * (-32) = 64.
Hence our first 6 terms in the GP are
-2, 4, -8, 16, -32 and 64.
Evaluate the expression for the given value of the variable.
29 + 5/6r
r = -1/2
find r
Hey there!
The solution to your question is
We simply plug the "r" value into the equation and solve:
29 + (5/6)(-1/2)
29 + -5/12
28 7/12

The circumference of Tyler's bike tire is 72 inches. What is the diameter of the tire? Please leave a detailed explanation of how you got your answer!! Thank You!
Answer:
22.91 inches
Step-by-step explanation:
circumference = 2πr
2πr = 72 inches
2 x [tex]\frac{22}{7}[/tex] x r = 72
[tex]\frac{44}{7}[/tex] x r = 72
Solving for r , divide both sides of the equation by 7/44
r = 11.454545 inches
diameter= 2 x radius
2 x 11.454545 inches = 22.91 inches

Jason bought a soft drink for 2 dollars and 8 candy bars He spent a total of 26 dollars how much did each candy bar cost
Answer: Each candy bar cost him 3$
Step-by-step explanation:
First you subtract 26-2 to get 24. This is since he purchased the drink for 2$. Now he uses the 24 dollars to buy 8 candy bars, to figure how much each is you have to divide. You divide 24 by 8 in order to get 3.

Which of the following pairs of inequalities are equivalent
x-5> 4 and 2x-10 >8
x- 5 >4 and 2x +10 >8
x+5 >4 and 2x+10 <8
ALL
Answer:
(a): [tex]x-5> 4[/tex] and [tex]2x-10 >8[/tex]
Step-by-step explanation:
Given
Pairs of inequalities
Required
Select which is equivalent
(a): [tex]x-5> 4[/tex] and [tex]2x-10 >8[/tex]
Multiply both sides of [tex]x-5> 4[/tex] by 2
[tex]2 * (x - 5) > 4 *2[/tex]
[tex]2 * x - 2*5 > 4 *2[/tex]
[tex]2x - 10 > 8[/tex]
Hence: [tex]x-5> 4[/tex] is equivalent to [tex]2x - 10 > 8[/tex]
(b): [tex]x-5> 4[/tex] and [tex]2x+10 >8[/tex]
Multiply both sides of [tex]x-5> 4[/tex] by 2
[tex]2 * (x - 5) > 4 *2[/tex]
[tex]2 * x - 2*5 > 4 *2[/tex]
[tex]2x - 10 > 8[/tex]
Hence: [tex]x-5> 4[/tex] is not equivalent to [tex]2x+10 <8[/tex]
(c): [tex]x+5> 4[/tex] and [tex]2x+10 <8[/tex]
Multiply both sides of [tex]x+5> 4[/tex] by 2
[tex]2 * (x + 5) > 4 *2[/tex]
[tex]2 * x + 2*5 > 4 *2[/tex]
[tex]2x + 10 > 8[/tex]
Hence: [tex]x+5> 4[/tex] is not equivalent to [tex]2x+10 <8[/tex]
A king owned land outside of his castle he has partitioned the land to give as gifts to his 5 sons what fraction of land did the king give to each of his sons here is zeke solution andy got 1/2 bill got 1/5 carl got 1/5 dirk got 1/8 and evan got 1/8 identify zeke's two errors correct them and explain why your answers are correct
Picture relating to the question is attached
Answer:
Andy = 1/2
Bill = 1/8
Carl = 1/8
Evan = 1/8
Dirk = 1/8
Step-by-step explanation:
According to the picture depicting the sharing of the land :
Fraction of the total rectangular plot = 1
Andy got a portion of the whole divided into 2 = 1/2
Fraction left after Andy's portion:
1 - 1/2 = 1/2
1/2 of the fraction left was divided equally between Dirk and Evan
Hence ;
1/2 of 1/2 = 1/2 * 1/2 = 1/4
Dirk's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Evan's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Fraction of land left :
1 - (1/2 + 1/8 + 1/8) = 1 - 3/4 = 1/4
1/4 was divided equally into 2 for Bill and Carl:
Bill's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
Carl's share = 1/4 ÷ 2 = 1/4 * 1/2 = 1/8
