The Sum Of Two Numbers Is 18 And Their Difference Is 4
Answer:
The two numbers are 7 and 11.
[711? Is this an ad? ← :)]
Step-by-step explanation:
Let A and B stand for the two numbers.
We are told that:
1) A+B=18, and
2) A-B=4
Take the first expression and rearrange to isolate A:
A+B=18
A=18-B
Use this in the second expression:
(18-B)-B=4
-2B = -14
B = 7
From (1) we find A:
A+B=18
A+7=18
A= 11
If A=11, then B=7 (from A+B=18)
CHECK:
Does A+B=18?
11 + 7 = 18? YES
Does A-B=4?
11 - 7 = 4? YES

how do you solve inequalities and how do you graph them?
Answer:
Graph a Linear Inequality
Step-by-step explanation:
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

( ,0)
Answer:
0
Step-by-step explanation:
If you replace y with 0 (which you do since you are given y = 0 and you are trying to find x from the (_,0) point), you get [tex]2x = 5x[/tex]. The only way for x to satisfy this is x = 0.
Which shows a difference of squares?
10 y squared minus 4 x squared
16 y squared minus x squared
8 x squared minus 40 x + 25
64 x squared minus 48 x + 9
Answer:
8x^2 - 40x + 25
Step-by-step explanation:
The terms that show a difference of squares are given by:
10y² - 4x²
16y² - x²
What is a difference of squares?It is when the square of two terms are subtracted, in the following format:
[tex]a^2 - b^2[/tex]
In this problem, the first two items are difference of squares, as:
[tex]10y^2 - 4x^2 = (\sqrt{10}y)^2 - (2x)^2[/tex]
[tex]16y^2 - x^2 = (4y)^2 - x^2[/tex]

Complete Question
The Henderson Hawks minor-league baseball team is giving away baseballs an
game. The balls cost $3 each and the towels cost $2 each. The team wants to give away 200 items and have 500 to spend. How many of each item should the team give away Show your
work or explain your reasoning.
Answer:
They should give away 100 balls and 100 towels
Step-by-step explanation:
Let the number of balls = x
Let the number of towels = y
x + y = 200........ Equation 1
y = 200 - x
$3 × x + $2 × y = $5000
3x + 2y = 5000...... Equation 2
3x + 2(200 - x)= 5000
3x + 400 - 2x = 5000
Collect like terms
3x - 2x = 500 - 400
x = 100
Number of balls to be given away = 100
Note:
y = 200 - x
y = 200 - 100
y = 100
Number of towels to be given away = 100
Therefore, they should give away 100 balls and 100 towels
Which values from this set {−36, −32, −16, 0, 4, 16} satisfy this inequality? −14x+6≥14 −32, −16, 0, 4, and 16 only 0, 4, and 16 only −36, −32, and −16 only −36 and −32 onlyWhich values from this set {−36, −32, −16, 0, 4, 16} satisfy this inequality? −14x+6≥14 −32, −16, 0, 4, and 16 only 0, 4, and 16 only −36, −32, and −16 only −36 and −32 only
Answer:
Step-by-step explanation:
Given the inequality −14x+6≥14, we are to find the range of x that will make the inequality true.
Given −14x+6≥14
Subtract 6 from both sides.
−14x+6-6≥14-6
-14x≥8
-7x≥4
Multiply both sides by -1
-(-7)x≤-4
7x ≤ -4
x≤-4/7
This shows that the values of x is always less than or equal to -0.57
Hence the values less tan the value of x in the inequality are -36, -32 and -16

Find the value of x
Answer:
134 degrees
Step-by-step explanation:
the angles in a triangle always add up to 180.
86+48=134
to find the last angle you subtract 180-134
this gives you 46 degrees
a straight line is always measured as 180 degrees.
180-46=134
so x=134 degrees

Jessie read three books in one week. At this rate, how many books will she read in 3 weeks?
Answer:
Jessie will read 9 books in 3 weeks.
Step-by-step explanation:
3 x 3 = 9
Answer: 9
Step-by-step explanation: If you need an equation, you can create one:
t = total number of books read
w = weeks
t = 3w
The 3 is there because she reads 3 books weekly, so you multiply the number of weeks by the number of books she reads.
Plug in 3 weeks:
t = 3(3)
t = 9 books
Jessie reads 9 books in 3 weeks.
