Twice a number divided by 6 is 42

Mathematics

X = a number

2x/6 = 42

Isolate the x, first multiply 6 to both sides

2x/6(6) = 42(6)

2x = 42(6)

2x = 252

Isolate the x, divide 2 from both sides

2x/2 = 252/2

x = 252/2

x = 126

126 is your answer

hope this helps

Hello!

To solve, we need to put this situation into an equation.

2x/6=42

Now we solve.

2x=252
x=126

I hope this helps!

Maria has a bag with 6 red marbles, 6 blue marbles, and 4 green marbles looking Maria picks one . She does not replace it and sh
Sati [7]

Answer: Hello there!

initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.

You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)

Now we want to know the probability that she gets a red marble on the second pick.

Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)

this is 6/15.

now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.

if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.

Then the correct answer is C.

Linda is building steps for her porch. What is the volume of the steps?
Greeley [361]

Answer:

The volume of the steps is:

  • <u>324,000 cm3</u>

Step-by-step explanation:

Remember that the volume regularly is:

  • Volume = height * width * depth.

There are many forms to solve this exercise, but I'll show you two:

1. Imagine that aren't steps but a big solid, then its volume would be:

  • Volume of big solid = 60 cm * 60 cm * 120 cm
  • Volume of big solid = 432000 cm3

Now you can subtract the volume of a small solid with measures 30 cm * 30 cm * 120 cm (<em>where is the blank for the step</em>):

  • Volume of a small solid = 30 cm * 30 cm * 120 cm
  • Volume of a small solid = 108000 cm3

Now you subtract:

  • Volume of the building steps = 432000 cm3 - 108000 cm3
  • <u>Volume of the building steps = 324000 cm3 </u>

2. The building steps are formed by three solid with volume 30 cm * 30 cm * 120 cm, so:

  • Volume of the building steps = 3 (30 cm * 30 cm * 120 cm)
  • <u>Volume of the building steps = 324000 cm3</u>

You are 55 feet tall and cast a 1010-foot shadow. A flagpole nearby casts a shadow that is 2828 feet. Which equation can you use
sergejj [24]
B. 5/10 = h/28
This is because 10 and 28 is simplified versions of 1010 and 2828, which are both the shadows, and they both either have to be on the top of the bottom, and 5 is a simplified version of 55 and 55 and 1010 have to go together

Factorise : a^2+4a-60 Step by Step​
NARA [144]

Answer:

Step-by-step explanation:

Sum = 4

Product = -60

Factors = 10 , -6

a² + 4a - 60 = <u>a² + 10a</u> - 6a + (-6) * 10

                    =a(a + 10) - 6(a +10)

                    = (a +10) (a -6 )
