Answer:
x=2<br/>y=1
Step-by-step explanation:
\left\{ \begin{array} { l } { 4 x + y = 9 } \\ { 3 x - 2 y = 4 } \end{array} \right.
4x+y=9,3x-2y=4
4x+y=9
4x=-y+9
x=\frac{1}{4}\left(-y+9\right)
x=-\frac{1}{4}y+\frac{9}{4}
3\left(-\frac{1}{4}y+\frac{9}{4}\right)-2y=4
-\frac{3}{4}y+\frac{27}{4}-2y=4
-\frac{11}{4}y+\frac{27}{4}=4
-\frac{11}{4}y=-\frac{11}{4}
y=1
x=\frac{-1+9}{4}
x=2
x=2,y=1

There are n=27 students in a certain Algebra 2 class. 18 out of them play basketball and 16 of them play baseball.
We also know 3 students play neither sport. This leaves 27-3=24 students playing sports.
The probability that a randomly chosen student plays basketball or baseball is:

Step-by-step explanation:
We are given the expression:
[tex]50x^3-20x+8x-21x^3-3x+15x-29x^3[/tex]
We want to simplify it, so we must combine the like terms. For this equation, the like terms are terms with x³ or x.
First, combine all the x³ terms.
[tex](50x^3-21x^3-29x^3)-20x+8x-3x+15x[/tex]
[tex](0x^3)-20x+8x-3x+15x[/tex]

Next, combine all the remaining terms, because they are all terms with an x.

In an exponential function, $(x)= a(b)", it is known that (5) = 15 and S(8) = 170. Which of the
following is closest to the value of b?
(1) 1.87
(3) 3.19
(2) 2.25
(4) 3.72
Answers
Answer:
b = 2.25
Step-by-step explanation:
Here, we want to get the value of b
from the question;
s(x) = ab^n
Firstly;
15 = a•b^5
Secondly
170 = a•b^8
Divide second by first
170/15 = ab^8/ab^5
11.33 = b^3
b is the cube root of 11.33
b = 2.25

Del contenido total de una lata de verduras de 220g,la masa drenada es de 110g. ¡Que fraccion representa la masa drenada del contenido total? ¿Que fraccion decimal corresponde a un 1/4? ¿Que tanto por ciento se representa con 1/4 o .25? ¿Que tanto por ciento del contenido total representa la masa drenada?
Answers
Explicación paso a paso:
Pregunta 1
El contenido total de verduras = 220 g
La masa drenada es de 110 g.
¿Qué fracción representa la masa drenada del contenido total?
= 110/220
= 22/11
La fracción es 11/22
Pregunta 2
¿Qué fracción decimal corresponde a 1/4?
la fracción decimal que corresponde a 1/4 es 0,25
Pregunta 3
¿Cuánto porcentaje está representado por 1/4 o 0,25?
= 0,25 * 100
= 25%
Pregunta 4
¿Cuánto porcentaje del contenido total representa la masa drenada?
= 110/220 * 100
= 11/22 * 100
= 0,5 * 100
= 50%
Greg wants to buy a new baseball bat. Store A has the bat originally priced at $245 and is having a 25% off sale. Store B's bat has an original price of $166 but is marked up 20%. Which store has the better price for the baseball bat?
Answers
Answer: Store A with price at $183.75 has the better price for the baseball bat
Step-by-step explanation:
Step 1
New price of baseball bat at store A= Original price - 25% off sale
$245- (25/ 100 x 245)
$245-$61.25
$183.75
New price of baseball bat at store B= Original price +20% mark up
=$166 + (20 /100 x 166)
=$166 + 33.2
$199.2
Step 2
Having that the price of bat at store A is =$183.75 and the price of bat at store B is =$199.2, The better price for the baseball bat is sold at Store A which is a cheaper option
Answer:
It is cheaper to buy the bat in Store A.
Step-by-step explanation:
Giving the following information:
Store A:
Selling price= $245
Discount= 25%
Store B:
Selling price= $166
Mark-up= 20%
We need to determine which store is cheaper to buy the bat:
Store A:
Discounted selling price= 245*0.75= $183.75
Store B:
Mark-up selling price= 166*1.2= $199.2
It is cheaper to buy the bat in Store A.
Here are 6 number cards -4, -2, -1, 5,6,8 arrange the cards into 3 pairs with the same total
Answers
Answer: See explanation
Step-by-step explanation:
We are informed that we should arrange -4, -2, -1, 5,6,8 arrange into 3 pairs with the same total. This will be:
= (-4,8), (-2,6), and (-1,5).
Let's check the total for each. This will be:
= (-4,8) = -4+8 = 4
(-2,6) = -2 + 6 = 4
(-1,5) = -1 + 5 = 4
