Raquel and her brother Marcus are huge sports fans. Combined they own 15 sports jerseys. Raquel owns double the amount of Marcus's jerseys plus an additional three. Use x to represent Marcus's amount of jerseys and y to represent Raquel's amount of jerseys.
Answer:
[tex]x = 4[/tex] -- Marcus
[tex]y = 11[/tex] -- Raquel
Step-by-step explanation:
Given
[tex]x =Marcus[/tex]
[tex]y = Raquel[/tex]
[tex]x + y = 15[/tex] -- Both
[tex]y = 2x + 3[/tex] -- Raquel
Required
Determine x and y
Substitute 2x + 3 for y in [tex]x + y = 15[/tex]
[tex]x + 2x + 3 = 15[/tex]
[tex]3x + 3 = 15[/tex]
Collect Like Terms
[tex]3x = 15-3[/tex]
[tex]3x = 12[/tex]
Divide both sides by 3
[tex]x = 4[/tex]
Substitute 4 for x in
[tex]y = 2x + 3[/tex]
[tex]y = 2 * 4 + 3[/tex]
[tex]y = 8 + 3[/tex]
[tex]y = 11[/tex]

b>a
a
Answer:
b
Step-by-step explanation:
According to the given angles in the question, angle b is greater than angle a.
What is inequality?Mathematical equations with inequalities on both sides are known as inequalities. In an inequality, we compare these two values as opposed to equations. Somewhere between, the equal sign is changed to a less than (or less than or similar to), bigger than (or greater or equal to), or just not equal to sign.
As per the given data from the question,
The side which has got a larger angle has the largest side.
The side c is greater than a and side b is also greater than a.
The remaining angle can be calculated as:
The sum of all angles will be equal to 360.
x + 75 + 90 + 105 = 360
x = 90°.

Valerie is 30 inches tall and casts a shadow that is 12
inches long. At the same time, ber teddy bear casts a
shadow that is eight inches long. How tall is the teddy
bear?
Answer:
20
Step-by-step explanation:
30:12 is the original ratio. So if you divide both sides by the numbers' GCF of 6 you'll get a simplified ratio of 5:2. Then multiply both sides by 4 to keep the ratio constant, then you'd get 20:8. So when the teddy bear casts a shadow of 8 inches long the actual teddy bear is 20 inches tall. Hope this helps!

Step-by-step explanation:
Rewrite this expression using the distributive property.
(3x2 + 4x-7)(x-2)
Answer:
D
Step-by-step explanation:
Each factor on the right has to be multiplied by the equation on the left and then you add them.
The expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.
To rewrite the expression (3x² + 4x - 7) ( x- 2) using the distributive property, we need to distribute each term in the first polynomial to each term in the alternate polynomial.
(3x² + 4x - 7) ( x- 2)
= 3x²( x- 2) + 4x( x- 2)- 7( x- 2)
Now, distribute each term
= 3x³- 6x²+ 4x²- 8x- 7x + 14
Combine like terms
= 3x³- 2x²- 15x + 14
Thus, using the distributive property, the expression (3x² + 4x - 7) ( x- 2) can be rewritten as 3x³- 2x²- 15x + 14.

Answer:
1. the quality of being made up of exactly similar parts facing each other or around an axis.
2. For something to be an odd function, it has to have symmetry to the origin, not the x-axis. This means that if it has a point like (a, b), it also has the point (-a, -b). For example, y = x is an odd function because it does this.

Hi there! I'm here to help. :)
Okay, so here you are solving for x. To solve for x, you must get it alone on one side of the equal sign. As we can see, it is not alone, and it is with 1 1/4 on the left side of the equal sign.
To get it alone, we need to subtract 1 1/4 from both sides. However, to subtract fractions, we need to make sure they have the same denominator. Looking at the fractions, we can see that they have two different denominators.
Begin by converting both fractions into improper fractions:
1 1/4 = 5/4
3 1/2 = 7/2
So now our equation looks like this: x + 5/4 = 7/2
Now we need to make it to where we our fractions have the same denominator.
Our current denominators are 4 and 2. The LCM (lowest common multiple) of 4 and 2 is 4, so you leave 5/4 as it is (because it's denominator is already 4) and you change 7/2.
Multiply 2 * 2 to make the denominator 4 in 7/2, but whatever you do to the denominator, you MUST do to the numerator. So multiply 7 * 2 = 14. Now your fraction looks like this: 14/4
Now we have:
1 1/4 = 5/4
3 1/2 = 14/4
Our denominators are the same now! Now here comes the easy part: We subtract! Do 3 1/2 - 1 1/4, or, 14/4 - 5/4. To subtract fractions, simply subtract the numerators and leave the denominators as is. 14 - 5 = 9, so 14/4 - 5/4 = 9/4.
Now our equation looks like this:
x = 9/4
LASTLY: All of your options are mixed numbers, so convert this improper fraction back into a mixed number. 9/4 = 2 1/4.
So, x = 2 1/4. :)
