Katie wants to include stickers in the gift bags for a party. Stickers come in packs of 25. She wants to give each of the 17 guests at least 10 stickers. How many packs of stickers will she need? Write an equation that describes this situation.
Answer:
170
Step-by-step explanation:
don't know if its right
i calculate it...hope it help a little
The equation that describes the given situation and the number of packs required are; 25x = (17 * 10) and x = 7 packs
How to write algebraic equations?
We are told that;
Each sticker comes in a pack of 25
Now, she wants to give each of the 17 guests at least 10 stickers.
Let the number of packs she will require be x. Thus, the expression to describe this situation is;
25x = (17 * 10)
x = (17 * 10)/25
x = 6.8 packs
Approximating to a whole number gives us 7 packs of stickers required.

Answer:
x = -3.5 or x = 1.7
Step-by-step explanation:
Start by factoring the left side.
We need to find two numbers that have a product of -210 (6 * -35) and a sum of 11...
-10*21=-210
-10+21=11
We can rewrite 11x as -10x+21x...
[tex]6x^2-10x+21x-35=0[/tex]
Then, factor the first and second half of the left side individually:
[tex]2x(3x-5)+7(3x-5)=0[/tex]
Since 2x and 7 are both being multiplied by 3x-5, we can combine them to get:
[tex](3x-5)(2x+7)=0[/tex]
Divide the equation by 3x-5:
2x+7=0
Subtract 7 from both sides
2x=-7
Divide both sides by 2
x=-7/2=-3.5
Now, we also have to consider another answer, in which we divide the equation by 2x+7 instead of 3x-5:
3x-5=0
Add 5 to both sides
3x=5
Divide both sides by 3
x=5/3≈1.7
Your total after 4 games of bowling was $28
and after 6 games it was $40. What was the
initial cost to rent the shoes before bowling
any games?
Answer:
$4
Step-by-step explanation:
Let x be the cost of a game of bowling and y be the cost to rent the shoes before the game then...
4x+y=28
6x+y=40
We can solve this system using elimination. In this scenario, we can eliminate y by subtracting the two equations...
-2x=-12
Divide both sides by -2
x=6
Plug 6 back in for x to solve for y
4(6)+y=28
24+y=28
Subtract 24 from both sides
y=4
It costs $4 to rent the shoes before bowling

Leyan bought 2 3/4 pounds of apples for $1.32 per pound. 1 1/2 pounds of peaches for $1.20 per pound, and some tomatoes. all from grocery store. the total cost of his purchase was $9.63.
How much money did leyan spend on tomatoes
Answer:
$ 4.20

2.2^x +2.2^-3 =5 solve for x
Answer:
x = 2.0172
Step-by-step explanation:
2.2^x+2.2^-3=5
-> 2.2^x+0.093914 = 5
-> + -0.93914 + -0.93914
-> 2.2^x = 4.906086
-> x = log(4.906086/log(2.2)

f(x)=3(2)^x ; x= -1 evaluate for X
Hey there!
f(x) = 3(2)^x
f(x) = 3(2)^-1
y = 3(2)^-1
y = 3 * 2^-1
y = 3 * 1/2
y = 3/1 * 1/2
y = 3(1) / 1(2)
y = 3/2
y ≈ 1 1/2
Thus, your answer is: y = 3/2 or y = 1 1/2

Assuming that no denominator equals zero, what is the simplest form of this expression?
Answer:
The answer is D
Step-by-step explanation:
The simplified form of the algebraic expression [tex]\frac{x+2}{x^{2} +5x+6} / \frac{3x+1}{x^{2} -9}\\[/tex] is [tex]\frac{x-3}{3x + 1}[/tex].
What is simplifying an algebraic expression?Simplification of an algebraic expression can be defined as the process of writing an expression in the most efficient and compact form without affecting the value of the original expression.
[tex]= \frac{x+2}{x^{2} +5x+6} / \frac{3x+1}{x^{2} -9}\\ \\ = \frac{x+2}{x^{2} +5x+6} * \frac{x^{2} -9}{3x+1}[/tex]
Solving in parts,
[tex]=x^{2} +5x + 6\\\\= x^{2} + 2x + 3x + 6\\\\=x(x+2) + 3(x+2)\\\\=(x+2)(x+3)[/tex]
[tex]= x^{2} -9\\\\= x^{2} - 3^{2}\\ \\=(x - 3)(x + 3)[/tex]
[tex]= \frac{x+2}{x^{2} +5x+6} * \frac{x^{2} -9}{3x+1}\\\\= \frac{x+2}{(x+2)(x+3)} * \frac{(x+3)(x-3)}{3x+1}\\ \\=\frac{x-3}{3x + 1}[/tex]
