simplify the following expression=(4ad)-1/13b x 16a/(13abc)-1
Answer:
(4ad) - 16/169c -1.
Step-by-step explanation:
Alright. Let's start.
(4ad) - [tex]\frac{1}{13}[/tex]b * [tex]\frac{16a}{13abc}[/tex] -1 is the expression.
So, by PEMDAS, we need to do the multiplication first. We can also say that 1/13b is the same as b/13.
(4ad) - 16ab/169abc -1 Now let's cancel out the b and a on numerator and denominator.
(4ad) - 16/169c -1.
Hope this helps!

foot of snow? I just need the y= blank part I’m really in need of this for a project thanks
Answer:
y= 2/3x
Step-by-step explanation:
Hi, the slope-intercept would be y= 2/3x. This is because the city receives 4 inches of snow every 6 hours. 4/6 simplified is 2/3.
Pleaseee helpp meeee
Answer:
7
Step-by-step explanation:
The new expression would be: 2(10) / 5 + 3. Using PEMDAS, first multiply 2(10) to get 20. Now you get: 20 / 5 + 3. Using PEMDAS, now divide 20 / 5 to get 4. The new expression is 4 + 3. Now, add to get 7 as your answer.
Hope it helps!

A clap of thunder is recorded at two weather stations that are 2 miles apart. Station A recorded the sound 3 seconds before station B. Since 1 mile is 5,280 feet and assuming sound travels at 1,100 feet per second, which equation can be used to determine the location of the thunder?
Answer:
C.
was right on edge 2021
The correct option is (C)
What is equation?An equation is a mathematical expression that contains an equals symbol.
Given:
Sound travels= 1100 feet per second
Stations are 2 miles apart from each other, i.e., 10560 feet.
Using,
x²/a² + y²/b²=1
So, 2c= 10560
c=5280
and, 2c-2a +3300 = 10560
2a= 3300
a= 1650
So, b²= c² - a²= 25155900
x²/2722500 + y²/25155900=1

Answer:
1/2
Step-by-step explanation:
There are 6 marbles that are either red or green out of 12 total marbles, so you have:
6/12 = 1/2
Answer:
1/2
Step-by-step explanation:
To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:
[tex]\frac{5+1}{12}[/tex] or [tex]\frac{6}{12}[/tex] which can be simplified to [tex]\frac{1}{2}[/tex].

The correct options are a and d.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
The value of X increased by 35%.
Here, we will use the percentage formula.
The value is increased by 35%.
That means,
100 + 35 = 135%
135% in decimal form is 1.35.
In expression form as subject to X,
X(1.35)
In expressed form,
= X + 0.35X
= 1.35X
Therefore, equivalent expressions are 1.35X and (1+0.35)x.

slove the equation below for y :
6x-4y=12
Answer:
[tex]y=-\frac{3(x +2)}{2}[/tex]
Step-by-step explanation:
We have an equation, and the question is asking for us to solve y. So to solve, we have to isolate y.
6x - 4y = 12
Subtract 6x from both sides :
-4y = 12 - 6x
Divide both sides by -4 :

I'm struggling a little bit can someone help?? A cell phone costs $850. You have a coupon for 15% off. How much will you pay for the phone? Include 13% tax
Answer:
722.50
Step-by-step explanation:
not exactly sure its right but i did use a calculator so I'm pretty sure it's right
Given:
850 dollars is the original price of the cell phone. (discount) coupon for 15% offtax is 13 percent.------------------------------------------------------------------
original price - discount = sales price
850 - (850 x [tex]\frac{15}{100}[/tex] ) = sales priceANSWER: $722.50 or [tex]\frac{1445}{2}[/tex]Include 13% tax... price + sales tax = total price of the phone

1) A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. If they share one sausage, they can eat it in 6 seconds. How long does it take each animal to eat a sausage alone?
2) A tourist ignores the warning signs and leaves food in his car while he goes for a hike. A mama bear and her cub open the car door in 6 seconds. How long would it take each bear to open the car door alone if the cub needs 9 more seconds than the mama bear?
3) A superhero and his sidekick simultaneously leave the city and fly toward a secret hideout that is 1800 km away. The superhero's speed is 100 km/h slower than the sidekick's speed, and so he arrives at the hideout 36 minutes after his sidekick. Find the speed of each.
4) A bear loves visiting his friend, the piglet. The distance between their houses is 300m, and the bear always walks from his house to the piglet's house in exactly the same amount of time. But today, the bear stops at a beehive after walking 1/4 of the distance. He eats honey for 2.5 minutes and then continues to the piglet's house at a speed 15 m/min faster than usual. The total journey to the piglet's house takes the exact same amount of time as it usually does, when the bear does not stop for honey. How long does the journey take?
Answer:
1) The puppy takes 10 minutes, the kitty takes 15 minutes.
2) The mama bear takes 9 minutes, the cub takes 18 minutes
3) The sidekick goes at 600 mph, the hero goes at 500 mph.
4) 10 Minutes
5) RSM is so hard, amiright?
Step-by-step explanation:
1) You can simplify the word problem into the equation 1/x + 1/x+5 = 1/6. For problems like these, you have to simplify the last part to a fraction, not a whole number. Then you just solve.
2) Same thing. 1/x + 1/x+9 = 1/6. Solve. Boom. Done.
3) A bit different, but it simplifies to 1800/x-100 - 1800/x = .6. Solve. C'mon, you should've been able to do this one.
4) Harder, simplifies to 75/x+225/x+15+2.5 = 300/x. You get the last part because the time the bear took is equal to the time it would normally take, which is the entire distance over the normal pace. Then you solve and there we go, most of your RSM homework is done.
Answer:
Puppy takes 10 sec.
Kitty takes 15 sec.
The mama bear can do it in 9 seconds
The cub can do it in 18 seconds
Superhero: 500 km/h
Sidekick: 600 km/h
