Answer:

z = -6

Step-by-step explanation:

5z + 2 = 3z - 10

z = -6

In this case the number of ways would be the number of events, in this case the events would be the total number of marbles since any of them can come out. so:

4 + 3 + 3 + 2 = 12

Therefore, the number of ways the event can occur is 12 ways.

Now, in the favorable outcomes of the event, it would come depending on what color the marble would be, whether it be red, blue, yellow or green.

In each color, the number of the favorable outcomes of the event would be the quantity of each marble, that is, 4 for red, 3 for blue, 3 for yellow and 2 for green.

Mai started a new exercise program. On the second day, she walked 5 minutes more than on the first day. On the third day, she increased her walking time from day 2 by 20% and walked for 42 minutes. Mai drew a diagram to show her progress.

Answers

Answer:

d = 30 minutes.

day one is equal to 30 minutes

day two is equal to 35 minutes

day three is equal to 42 minutes

Explanation:

The first step is to figure out how much day 2 was worth in total.

Using the model, we can see that 5 of the boxes from day three is equal to day 2.

42/6=7.

One of the boxes equals 7 minutes.

Next we find what all 5 of them equal.

7*5=35.

Day two was worth 35 minutes in total.

The next step is to figure out what d equals. In order to do that, we need to solve the equation:

d + 5 = 35.

subtract 5 from both sides.

d = 30.

Now we know that day one/D is equal to 30 minutes.

Day one: 30 minutes

Day two: 35 minutes

Day three: 42 minutes.

Hope that this is what your looking for. Have a good day and good luck!

Explain why the value of 0.6 is greater than the value of 0.39.

i know why... i just need help explaining plz! i will give brainliest

Answers

Answer:

the value 0.6 is greater than 0.39 bc 0.6 is a bigger value than 0.39 as u go down the values get more bigger and as u go up the values get more smaller. try this if not then I will tell u another thing.

Answer is 0.60 > 0.39

Decimal place value:

The decimal place value is the place value of the digits in a decimal number. We know that place value is the numerical value represented by a digit in a number.

Ex: 0.50 > 0.49 as the tenth place of 0.50 is more than 0.49.

Here,

0.6 = 0.60

0.60 > 0.39 as the tenth place of 0.6 i.e., 6 is greater than 0.39 i.e., 3.

How many mint chocolate chip cupcakes did they sell? *
Hint: Three-digit number

Answers

Answer:

96 cupcakes

Step-by-step explanation:

If they sold 4 times as many cupcakes as shamrock cookies, and they sold 24 shamrock cookies, then all you need to do is 24x4, which equals 96.

They sold a total of 18 dozens of chocolate chip cupcakes.

What is an equation?

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of shamrock shaped cookies, y for horseshoe shaped cookies and z for mint chocolate cupcakes.

He sold a total of 24 dozens, hence:

x + y + z = 24 (1)

The sold 4 time shamrock shaped cookies as cupcakes, hence:

z = 4x (2)

Also:

x = 3y (3)

From the equations:

x = 4.5, y = 1.5 and z = 18

They sold a total of 18 dozens of chocolate chip cupcakes.
