(1 + 9.8k)(2.8) simplified
Answer:
2.8 + 27.44k
Step-by-step explanation:
Algebraic Simplification
The rules of algebra can be applied in some situations to make expressions simplified or expanded, according to the specific needs of each problem.
We are given the expression:
(1 + 9.8k)(2.8)
It's a sum and a product. We cannot add the independent term with the variable term, so we can only multiply the factor and the contents of the parentheses as follows:
(2.8)1 + (2.8)9.8k
Operating:
2.8 + 27.44k

Gerry and Tony live 11 miles apart. Gerry leaves his home at 2:00 PM and bikes toward Tony's house at 25 miles/hour. At the same time, Tony leaves his home and bikes toward Gerry's house at 30 miles/hour. They wave as they pass each other. As soon as each boy reaches the others' home, they turn back around towards their own homes. This time, they stop when they see each other. How far are they from Gerry's home when they stop?
Please write an equation or more than one equation using Distance=Rate*Time.

:) please give a heart for thanks
and brainliest crown :)
Step-by-step explanation:
For both d=r*t
Each bikes to others house and leave at the same time so for Tony,
11 = 30*t
t= 11/30 hours
for Gerry,
11 = 25*t
t= 11/25 hours
Comparing these, with LCD,
Tony's time is 55/150
Gerry's time is 66/150
So Tony got to Gerry's house 11/150 hours quicker than Gerry got to Tony's house.
Now they turn around and head back toward each other. If they leave at the same exact time, the elapsed time for each until they met would be the same so t (for tony) = t (for gerry), but Tony got a head start.
We start the stopwatch when Gerry turns around 11/150 hours after Tony has turned around. If Gerry's time to where they meet from Tony's house t(gerry), then Tony's time from Gerry's house is t(gerry) + 11/150
Step-by-step explanation:
For both d=r*t
Each bikes to others house and leave at the same time so for Tony,
11 = 30*t
t= 11/30 hours
for Gerry,
11 = 25*t

El tripe de a edad de pedro mas 2 es igual a la edad actual de pedro mas 6. ¿Cuál es la edad actual de pedro?
Answer: Pedro tiene 2 años.
Step-by-step explanation:
Definamos la variable P como la edad de Pedro.
Sabemos que " El triple de la edad de pedro, más 2, es igual a la edad actual de pedro más 6"
Esto se escribe como:
3*P + 2 = P + 6.
Para encontrar la edad de Pedro, tenemos que resolver esa ecuación.
Para hacerlo, el primer paso es llevar todos los términos con "P" al lado izquierdo, y los términos sin "P" al lado derecho.
3*P - P = 6 - 2
2*P = 4
Ahora podemos dividir por 2 en ambos lados:
2*P/2 = 4/2
P = 2
Entonces podemos concluir que Pedro tiene 2 años.

What is it? A or B I've been stuck for a while please help
Answer:
Correct choice: B
Step-by-step explanation:
System of non-linear equations
It's given the following system of equations:
[tex]y=x^2+3x+5[/tex]
[tex]y=x+13[/tex]
We'll use the substitution method. Substituting y from the first equation into the second equation, we have:
[tex]x^2+3x+5=x+13[/tex]
Moving all terms to the left side:
[tex]x^2+3x+5-x-13=0[/tex]
Simplifying:
[tex]x^2+2x-8=0[/tex]
Factoring:
[tex](x+4)(x-2)=0[/tex]
There are two solutions:
x=-4, x=2
The first solution gives a value for y:
y=-4+13=9
First solution: (-4,9)
The second solution gives a value for y:
y=2+13=15
Second solution: (2,15)
Correct choice: B
