First do PEMDAS
There's no parenthesis. So move on to exponent. There's also no exponents. Move on to multiplication. There it is.

12×5=60.

There's no division so now next one is addition. Hey look! There is addition.

60+55=115.

So 115 is your answer.

Rosa climbs a 16-meter tower to ride a straight water slide. After landing in the slash pool, she walks 9 meters back to the bas

erastova [34]

Answer:

The length of slide is 18.36 meters

Step-by-step explanation:

The given scenario forms a right-angled triangle where

The height of tower id perpendicular, the distance between slash pool and base of tower is base and the length of slide will be hypotenuse.

Height of tower = h = 16 meters

Distance between slash pool and base of tower = b = 9 meters

Length of slide = s = ?

As it is a right angled triangle, we can use Pythagoras theorem to find the length of slide

Pythagoras theorem states that:

$(Hypotenuse)^2 = (Base)^2+(Perpendicular)^2\\s^2 = b^2+h^2\\s^2 = (9)^2+(16)^2\\s^2 = 81+256\\s^2 = 337\\s^2 = 18.36\ meters$

Hence,

The length of slide is 18.36 meters

Determine the value of x in the equation x+5x=5x+7

12345 [234]

$\text{Hey there!}$

$\mathsf{Determine\ the\ value\ of\ x\ in\ the\ equation\ x+5x=5x+7.}$

$\mathsf{SIMPLIFY\ both\ sides\ of\ your\ equation}$

$\mathsf{x+5x=5x+7}$

$\mathsf{COMBINE\ your\ like\ terms}$

$\mathsf{(x+5x)=(5x+7)}$

$\mathsf{The\ RIGHT\ side\ DOES\ NOT\ have\ any\ like\ terms\ so\ we\ can}\\\mathsf{can\ leave\ alone}$

$\mathsf{x+5x= 6x}$

$\mathsf{Your\ new\ equation: 6x=5x+7}$

$\mathsf{SUBTRACT\ by\ 5x\ on\ your\ sides}$

$\mathsf{6x-5x}\\\mathsf{=}\\\mathsf{7-5x}$

$\mathsf{SOLVE\ your\ equation\ above\uparrow}$

$\mathsf{If\ you\ SOLVED\ correctly\ you\ SHOULD\ have\ the\ VALUE\ of\ x}$

$\boxed{\boxed{\mathsf{Thus\ your\ answer\ is\ x=7}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
