Answer:
Choices C and D
Step-by-step explanation:
The most simplest way is just to solve each one and see which two have the same answer as the first expression.
But you could also see that both of the [tex]\frac{4}{7}[/tex] are going to cancel each other out so you are left with [tex]-\frac{8}{9} +\frac{9}{8}[/tex] which is also choice C.
For choice D I distributed the negative one to the insides of the parenthesis that left me with [tex]-\frac{4}{7}-\frac{8}{9}+\frac{4}{7} +\frac{9}{8}[/tex] which is the same expression as the first one.

Una caja contiene bolas blancas, negras y rojas. Si la quinta parte de las bolas son blancas, la séptima parte son
negras y hay 7 bolas rojas, ¿cuántas hay en total?
Answers
Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23

The expression x^3 + ax^2 - 15x + b has a factor of x – 2 and leaves a remainder 75 when divided
by x + 3. Find the value of a and of b.
Answers
Answer:
The expression x^3 + ax^2 - 15x + b has a factor of x – 2 and leaves a remainder 75 when divided
by x + 3. Find the value of a and of b.
Let p(x) = x3 + ax2 + bx +6
(x-2) is a factor of the polynomial x3 + ax2 + b x +6
p(2) = 0
p(2) = 23 + a.22 + b.2 +6 =8+4a+2b+6 =14+ 4a+ 2b = 0
7 +2 a +b = 0
b = - 7 -2a -(i)
x3 + ax2 + bx +6 when divided by (x-3) leaves remainder 3.
p(3) = 3
p(3) = 33 + a.32 + b.3 +6= 27+9a +3b +6 =33+9a+3b = 3
11+3a +b =1 => 3a+b =-10 => b= -10-3a -(ii)
Equating the value of b from (ii) and (i) , we have
(- 7 -2a) = (-10 - 3a)
a = -3
Substituting a = -3 in (i), we get
b = - 7 -2(-3) = -7 + 6 = -1
Thus the values of a and b are -3 and -1 respectively.

Answer:
x=-8
Step-by-step explanation:
2x−3=5x+20+1
2x−3=5x+21
2x−3+3=5x+21+3
Then simplify those numbers
2x=5x+24
Then subtract 5x from both sides
Answer:
x=-8
Step-by-step explanation:
open brackets first
2x - 3 = 5x + 20 + 1
2x - 3 = 5x + 21
transpose
2x - 5x = 21+ 3
calculate
-3x = 24
x= -3/24
x= -8

A professional baseball player hits a homerun on a .75kg baseball. The ball accelerated at a rate of 1200m/s2. How much force did the player hit the ball with?
Answers
Answer:
The force the player hit the ball with is 900 N
Step-by-step explanation:
Given;
mass of the baseball, m = 0.75 kg
acceleration of the ball, a = 1200 m/s²
The force the player hit the ball with is given by the following equations;
F = ma (based on Newton's second law of motion)
where;
F is the applied force
m is mass of the baseball
a is the acceleration of the baseball
F = ma
F = (0.75 x 1200)
F = 900 N
Therefore, the force the player hit the ball with is 900 N
