allison has 5 times as many baseball cards as football cards.in all,she has 120 baseball and football cards.how many baseball cards does she have?
Answers
So x + 5x = 120
6x = 120
x = 120/6 = 20
Allison 5x baseball cards so 20*5 = 100 baseball cards
Out of the total of 120 cards, Allison has 100 baseball cards.
Allison has a total of 120 baseball and football cards.
The baseball cards are 5 times the football cards so assuming the football cards were denoted as x, the baseball cards would be denoted as:
= 5 × x
= 5x
The cards in her possession can be found by solving for x:
Baseball cards + Football cards = 120
5x + x = 120
6x = 120
x = 120 / 6
x = 20 football cards
Baseball cards:
= 5x
= 5 x 20
= 100 baseball cards
In conclusion, she has 100 baseball cards.

Help me with this problem 9x-(2x+8)=. And show your work? I'll be giving BRAINILEST!
Answers
So, to do that, first look at the symbol before the parenthesis.
In this case it's a -.
So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)
So,
9x - 2x - 8
Or simplified,
7x - 8
7x + 8 is your answer

What is the value of g? 25(g−7)=3 Enter your answer in the box
Answers
25g-178=0
g= 178:25=
7.12
Answer: The value of g is 7.12.
Explanation:
The given equation is,
[tex]25(g-7)=3[/tex]
Use distributive property to solve the equation.
[tex]25g-175=3[/tex]
Using addition property of equality add 175 both sides.
[tex]25g-175+175=3+175[/tex]
[tex]25g=178[/tex]
Using division property of equality, divide both sides by 25.
[tex]\frac{25g}{25} =\frac{178}{25}[/tex]
[tex]g=\frac{178}{25}[/tex]
[tex]g=7.12[/tex]
Therefore the value of g is 7.12.
To check the answer put the value of g in given equation.
[tex]25(7.12-7)=3[/tex]
[tex]25(0.12)=3[/tex]
[tex]3=3[/tex]
LHS is equal to RHS, therefore the value g=7.12 is correct.
what is 2a^2-14=-24 factored
Answers
______________________________________
→ {assuming the question meant to be written as:
"What is: 2a² − 14x= -24 ; factored?" } ;
______________________________________
Explanation:
______________________________________
Given: " 2a² − 14x= -24 "; factor this equation ;
______________________________________
Simplify the equation by dividing the entire equation (each side) by "2" ;
______________________________________
{ 2a² − 14x = -24 } / 2 =
a² − 7 = -12
Now, add "12" to each side of the equation:
____________________________________
a² − 7x + 12 = -12 + 12 ;
to get:
a² − 7 + 12 = 0 ;
__________________________________
Now, what factors of "12"; when added together, equal "-7"?
6, 2 = 8
-6 -2 = -2,
12, 1 = 13,

So; "a² − 7x + 12 = 0" ; factors to:

what is the rule for this sequence? 1, 4, 16, 64, 256
Answers
1 * 4 = 4
4 * 4 = 16
16 * 4 = 256
and so on.
Hope this helps!
Final answer:
The rule for the given sequence is to multiply the previous term by 4. The sequence follows a pattern of 4 raised to the power of increasing integers starting from 0.
Explanation:
The sequence given is 1, 4, 16, 64, 256. To find the rule for this sequence, let’s examine the relationship between the consecutive numbers.
1 multiplied by 4 is 4
4 multiplied by 4 is 16
16 multiplied by 4 is 64
64 multiplied by 4 is 256
So, the rule for this sequence is to multiply the previous term by 4 to get the next term. Another way to express this is that each term is 4 to the power of n, where n is an increasing integer starting from 0 (4^0 = 1, 4^1 = 4, 4^2 = 16, and so on).

Next the word "of" tells us we need to multiply so we multiply .05 by 60.
(.05) (60) = 3.00

Joshua's goal is to sell more than 20 items at a farmers' market. So far, he has sold 6 items. Each of his customers buys 2 items. Let c represent the number of additional customers Joshua must have to meet his goal. Drag and drop the answer into the box to correctly complete the statement.
Answers
Joshua needs 17 additional customers to meet his goal of selling more than 20 items at the farmers' market.
Explanation:To find the number of additional customers Joshua must have to meet his goal, we first need to calculate the number of items he has already sold. Joshua has sold 6 items, and each customer buys 2 items. So, the number of customers Joshua has served is 6 / 2 = 3 customers.
To meet his goal of selling more than 20 items, Joshua would need to have c additional customers. Therefore, the number of additional customers is 20 - 3 = 17 customers.
Final answer:
Joshua has sold 6 items and each customer buys 2. To meet his goal of selling more than 20 items, he must solve the inequality 6 + (2 × c) > 20 to find the number of additional customers needed. After solving, he needs more than 7 additional customers.
Explanation:
The subject question involves creating an algebraic expression to help Joshua determine the number of additional customers he must have to meet his goal of selling more than 20 items at a farmers' market. Joshua has already sold 6 items, and each customer buys 2 items. We let c represent the number of additional customers Joshua needs. To solve this problem, we need to create an algebraic equation and solve it for c.
Joshua's goal: sell > 20 items
Joshua's current sales: 6 items
Items per customer: 2 items
Additional customers needed: c
The equation will be:
6 + (2 × c) > 20
To find c, we subtract 6 from both sides of the inequality:
(2 × c) > 14
Then we divide both sides by 2:
c > 7
Therefore, Joshua needs more than 7 additional customers to meet his goal of selling more than 20 items.
Use multiplication to solve the proportion. Y/9=44/54. What is Y
Answers
9(Y/9)=9(44/54)
Y=7 1/3 or 22/3
To solve the given proportion using multiplication, cross-multiply by multiplying the numerators and denominators, and then divide to find the value of Y, which is approximately 7.33.
Explanation:In mathematics, a proportion is an equation stating that two ratios are equal. It expresses the relationship between quantities. For example, if a/b = c/d, where b and d are not zero, it forms a proportion.
To solve the proportion Y/9 = 44/54 using multiplication, we can cross-multiply.
Multiply 9 by 44 and then divide by 54 to find Y
9 * 44 = 396
396 / 54 = 7.33
So, Y is approximately 7.33

If a number is ____, then the number is less than its absolute value. (Can you help me fill in the blank?in class we were learning about positive and negative numbers such as -5 and 5 and/or +5)
Thank you!
Answers
Absolute value is basically asking how far away something is from 0.
So say you had a number, 7. 7's distance from 0 is 7, so it would still be 7.
However, when absolute value really plays in is negative numbers. If you had -7, the distance from 0 would still be 7. It wouldn't be -7, so the absolute value of -7 would be 7.
And a negative version of a number is always less than the positive number.
