For a school fund-raiser, students sold T-shirts with the school logo for $14. PLEASE HELP!
They sold sweatshirts with the school logo for $20.
They sold 233 pieces of clothing and raised $3,748.
How many of each type of shirt did they sell at the fund-raiser?
Let x = the number of T-shirts sold.
Let y = the number of sweatshirts sold.
Answer:
The 3 problem
Step-by-step explanation:
Answer:
The answer is C) x+y = 233, 14x + 20y = 3748
Step-by-step explanation:
x(number of t-shirts sold) + y(number of sweatshirts sold) = 233 (total number of pieces of clothing sold)
14x (14 is the cost of each t-shirt and since x = number of t-shirts sold then it is 14x or 14 multiplied by number of t-shirts sold) + 20y (20 is the cost of each sweatshirt and since y = number of sweatshirts sold then it is 20y or 20 multiplied by number of sweatshirts sold) = 3748 (total of money raised)
Nicole wants to buy a charm bracelet. Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet. Flynn Jewelers, in contrast, charges $27 per charm and $11 for the bracelet. If Nicole wants to add a certain number of charms to her bracelet, the cost will be the same at either jewelry shop. How many charms would that be? What would the total cost of the bracelet be?
Answer:
There are 8 number of charms
Total cost = $227
Step-by-step explanation:
Let
Number of charms = c
Summerfield Fine Jewelry charges $26 per charm, plus $19 for the bracelet.
26c + 19
Flynn Jewelers charges $27 per charm and $11 for the bracelet
27c + 11
How many charms would that be ?
Equate the cost at both jewelry shop
26c + 19 = 27c + 11
Collect like terms
26c - 27c = 11 - 19
-c = - 8
c = 8
There are 8 number of charms
What would the total cost of the bracelet be?
Using any of the jewelry shop cost
Flynn Jewelers cost
= 27c + 11
= 27(8) + 11
= 216 + 11
= 227
Total cost = $227

What is the value of x in the equation x + 5.1 = 0
Answer:
-5.1
Step-by-step explanation:
x + 5.1 = 0
- 5.1 -5.1
x + 0 = -5.1
x = -5.1
The value of x is -5.1
Given,
x + 5.1 = 0
We need to find the value of x.
How do we find the value of a variable in an expression?We always keep the required variable on one side and keep all the other variables on the other side of the equation.
Example:
x + b + n = 2 + 2x
We need to find x.
Since we have two x terms
We will keep both the terms on one side.
b+ n - 2 = 2x - x
2x - x = b + n -2
x = b + n - 2 is our x value.
We have,
x + 5.1 = 0
Subtracting 5.2 on both sides.
x + 5.1 - 5.1 = 0 - 5.1
x = - 5.1
Thus the value of x is -5.1

Answer:
x = 60
Step-by-step explanation:
In order to make L parallel (||) to M, you want to prove that the angles are same-side interior angles since the Same-Side Interior Angle Theorem only works for parallel lines cut by a transversal.
In order to make the angles (marked with the expressions) same-side interior angles, they have to add up to 180 degrees because they are supplementary angles.
Make an equation where the two angles add up to (equal) 180.
(x - 5) + (2x + 5) = 180Combine like terms on the left side of the equation.
3x = 180Divide both sides of the equation by 3.
x = 6060 is the value of x that will make L || M.
To quickly find the product of a whole number time 1000, add *Blank* Zeroes to the number
Answer:
Add three zeros to the end.
Step-by-step explanation:
When you add three zeros, the result is equivalent to when multiplying by 1000. For example, 20 times 1000 is 20,000.

use a number line to find the difference-6.5 - 2
Answer:
The answer would be -8.5
Step-by-step explanation:
If you start at -6.5, to find the difference (subtract) you would move left two whole spaces to get to -8.5.
On the other hand, if you were to start at 6.5 and subtract 2, your answer would be 4.5.

Which equation does not represent a function? Why? A) y = x2; There are two outputs for each input. B) y2 = 4x; There are two outputs for each input. C) y = x; The output value is the same as the input value. D) y = −x; The output value is the opposite of the input value.
Answer:
B) y² = 4x; There are two outputs for each input
Step-by-step explanation:
For an equation to be called a function, the input values for x must only result in a single output for y.
Based on this definition if a function, the functions y = x², y = -x and y = x are all functions because for any value of x imputed in them, we can only get one equivalent value of y.
The only exception is the function y²= 4x
For this function, for any value of x, there will be more than one output for y. Take x = 1 for example
y² = 4(1)
y² = 4
y = ±√4
y = ±2
This shows that y = 2 and -2
Also if x = 4
y² = 4(4)
y² = 16
y = ±√16
y = ±4
y = 4 and -4
No matter the value of x imputed, the output value y will always be two (a positive and a negative value)
Hence, option B is correct.

B
