Lamont has purchased 20 trading cards and wants to have at least 50 trading cards. Write and solve an inequality to nd the number of trading cards Lamont needs. Select all of the true statements.
Given:
Lamont has purchased 20 trading cards.
He wants to have at least 50 trading cards.
To find:
The inequality for the number of trading cards Lamont needs and solve it.
Solution:
Let x be the number of trading cards Lamont needs.
He has 20 trading cards. So,
Total cards = x + 20
It is given that, he wants to have at least 50 trading cards. It means, total card must be greater than or equal to 50.
[tex]x+20\geq 50[/tex]
Subtract 20 from both sides.
[tex]x+20-20\geq 50-20[/tex]
[tex]x\geq 30[/tex]
Therefore, the required inequality is [tex]x+20\geq 50[/tex] and solution is [tex]x\geq 30[/tex].
The number of trading cards that Lamont needs will be at least 30 trading cards.
From the information given, we are informed that Lamont has purchased 20 trading cards and wants to have at least 50 trading cards.
Therefore, the number that will be needed more will be:
= 50 - 20 = 30
Therefore, he'll need at least 30 more cards.

Solve: 12r-6s=t for r
can someone please help me I've been stuck on this for so long
Answer:
x = -3, y=2
Step-by-step explanation:
x+3y =3
3y -2x =12
Solve the first equation for x
x = 3-3y
Substitute this into the second equation
3y -2(3-3y) =12
Distribute
3y -6 +6y =12
Combine like terms
9y -6 =12
Add 6 to each side
9y-6+6 =12+6
9y =18
Divide each side by 9
9y/9 =18/9
y = 2
Now find x
x = 3 -3y
x = 3-3(2)
x = 3-6
x = -3
Answer:
x = -3 y = 2
Step-by-step explanation:
x + 3y = 3
2x - 3y = -12
3x = -9
x = -3

Given h(x) = -x2+3x, find h(5).
Answer:
-10, 40, or 5
Step-by-step explanation:
There are three ways of looking at this problem.
1.
h(x) = -x^(2) + 3x
When finding h(5), that is like saying that in the case that x = 5, find the value of the given expression,
using that knowledge, we can say
h(5) = -(5)^(2) + 3(5)
simplify
= - (25) + (15)
= -10
2.
h(x) = (-x)^(2) + 3x
Again,
When finding h(5), that is like saying that in the case that x = 5, find the value of the given expression,
using that knowledge, we can say
h(5) = (-5)^(2) + 3(5)
simplify
=25 + 15
= 40
3.
h(x) = -2x + 3x
Again,
When finding h(5), that is like saying that in the case that x = 5, find the value of the given expression,
using that knowledge, we can say
h(5) = -2(5) + 3(5)
simplify
= -10 + 15
= 5

A triangle has three sides(4x),(2x-6),and(10-x). Using the variable x, write an expression to define the perimeter
Answer:
5x+4
Step-by-step explanation:
well the perimeter is the sum of all sides
so we have
[tex]P=4x+2x-6+10-x\\\\P=(4x+2x-x)+(-6+10)\\\\P=5x+4[/tex]
Answer:
P = 5x+4
Step-by-step explanation:
To find the perimeter, sum the sides
A triangle has 3 sides
P = 4x+ 2x-6 + 10-x
Combine like terms
P = 4x+2x-x -6+10
P = 5x +5
Solve the inequality for x. - 1 - 6x - 6 > - 11 - 7x
Answer:
The answer is
[tex]x > - 4[/tex]Step-by-step explanation:
[tex]- 1 - 6x - 6 > - 11 - 7x[/tex]
Simplify the inequality
That's
[tex] - 6x - 7 > - 11 - 7x[/tex]
Add 7 to both sides of the inequality
[tex] - 6x + 7 - 7 > - 11 + 7 - 7x \\ - 6x > - 4 - 7x[/tex]
Add 7x to both sides of the inequality
[tex] - 6x + 7x > - 4 + 7x - 7x \\ x > - 4[/tex]
We have the final answer as
[tex]x > - 4 [/tex]
Hope this helps you
The solution to the inequality [tex]- 1 - 6x - 6 > - 11 - 7x[/tex] is [tex]x > -4.[/tex]
To solve the inequality [tex]- 1 - 6x - 6 > - 11 - 7x[/tex], we can start by simplifying both sides of the inequality:
[tex]-1 - 6x - 6 > -11 - 7x[/tex]
Combine like terms:
[tex]-7 - 6x > -11 - 7x[/tex]
Add 7x to both sides:
[tex]-7 - 6x + 7x > -11 - 7x + 7x[/tex]
[tex]-7 + x > -11[/tex]
To isolate "x," we can subtract -7 from both sides:
[tex]-7 + x - (-7) > -11 - (-7)[/tex]
Simplifying further:
[tex]x > -11 + 7[/tex]
[tex]x > -4[/tex]
Therefore, the solution to the inequality is [tex]x > -4.[/tex]
