Answer:
20 | 30
Step-by-step explanation:
Multiply 2/5 by 50 to find the tickets for children
2*50/5
= 100/5
= 20
To find the tickets sold for the other party we subtract 20 from 50
50 - 20
= 30
Answer:
20 children got tickets.
Step-by-step explanation:
20/50 = 2/5

Step-by-step explanation:
Alex wants to buy a case of drinks, he doesn’t have enough. The cost of the case is $30. He already has $2. He gets $8 every hour for work. How many hours does he need to work to get the amount he needs? Explain what your solution means in the context of the problem.
Answer:
Alex will need to work 4 hours.
Step-by-step explanation:
We know that Alex already has $2. This means that to get $30 he now only needs to get $28. If he gets $8 per hour, we know that 8 x 3 = 24, but that isn't enough. In this case, 3 is how many hours he works. Because $24 isn't enough, he needs to work 4 hours to get $32 in order to buy the case. Even though he has more money than he needs, he will be able to buy the case and save some extra money.
Answer:
3.5
Step-by-step explanation:
Wright, an equation first like this,
2+8x=30 because he needs 30 dollars but already has 2 and earns 8 dollars per hour.
Solve:
2 + 8x = 30
30-2= 28
28/8= 3.5 so he would need to work 3.5 hours.

back to Ratios, Page 1
A proportion is similar to a ratio, except that it indicates a part of a whole, and so the numerator arises from the denominator. For instance, a researcher might say that, for every ten students in the residence hall, five were women. Five over ten (5 / 10) is a proportion. Proportions must have all of the numbers in the same units, and are frequently written as fractions.
What happens when you want to write a proportion, but the numbers are given in different units? Suppose you were asked to write the proportion of 3 cups to 56 ounces (3 cups out of 56 ounces). You must write a proportion of either cups to cups (cups:cups) or ounces to ounces (ounces:ounces), so you will have to convert one of the numbers so that both numbers are expressed in the same unit of measurement. Let's convert cups to ounces so we can express the ratio as ounces:ounces. Since there are 8 ounces in one cup, 3 cups are equal to 24 ounces:
3 cups * 8 ounces/cup = 24 ounces
Now the two numbers 3 cups and 56 ounces can be written as the following ratio:
24 ounces to 56 ounces,
24:56,
or, now that the unit of measurement is the same, 24:56 can also be written as a proportion:
24/56
You may need to solve some problems involving ratios.
If you divided 36 into two parts in the ratio of 1:2 and one part is a and the other is b, you can find the value of a and b:
You know that
a+b = 36
And
a/b = 1/2
You can use these equations to solve for a and b, or you can use the following simple method:
Find out how many units are in 1 part of the ratio. To do this, divide the total by the number of parts.
Number of parts: 1 + 2 = 3.
Number of units in each part: 36/3 = 12.
Then, multiply the number of units in each part by the number of parts in each variable.
a = 1 * 12 = 12
b = 2 * 12 = 24
As an aside . . .
Percentages are so frequently used that we should spend a little time on them here. The powerful thing about percentages is that they all have the same denominator: 100. When two fractions have the same denominator, comparisions can be made very easily.
0.21 = 21% = 21 / 100

how many solutions dose 3x+2=2x+2+x have explain why below remember explain
Answer:
All real numbers are solutions.
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x+2=2x+2+x
3x+2=(2x+x)+(2)(Combine Like Terms)
3x+2=3x+2
3x+2=3x+2
Step 2: Subtract 3x from both sides.
3x+2−3x=3x+2−3x
2=2
Step 3: Subtract 2 from both sides.
2−2=2−2

Ariel said that in the expression 2x + 2x2 - 6, the 2x and the 2x2 are considered like terms. Her friend, Kamika said they are not considered like terms. Who is correct? Explain why.
Answer:
If by "2x2" you mean 2x², Kamika would be correct. The exponents must be the same for them to be like terms.

Graph the image of D(4,7) after a translation 8 units left and 8 units down.
Answer:
(-4,-1)
Step-by-step explanation:
Answer:
(-2,-1)
Step-by-step explanation:
If it goes to the left that means its decreasing in its x value.
So 4-8=-2
When it goes down its means it's decreasing in its y value.
So 7-8=-1
Put that all together and you get (-2,-1)
1. Three pounds of M&M’s cost $7.50. At this rate, what is the cost of 7 pounds?
2. Three pounds of M&M’s cost $7.50. How many pounds can you buy with $50?
Answer:
1. 17.50
2. 6
Step-by-step explanation:
1A: First you have to divide the cost by the three pounds to get the price per pound. Now that you have that answer you multiply it by 7 to get the price of 7 pounds.
2A: You can buy 6 pounds because if you multiply 7.5 x 6 you get 45 which you cannot add one more 7.50 so that is your final answer.
Hope this helps you ^^

(10x11)-20+1=
if show work i will mark brainliest
Answer:
91
Step-by-step explanation:
10x11=110-20=90+1 = 91
Hope this helps plz hit the crown ;D
Answer:
The answer is 91.
Step-by-step explanation:
(10 x 11) - 20 + 1
The first step would be to do the parentheses which would give you 110.
110 - 20 + 1
Next you can subtract 20 from 110 which would give you 90.
90 + 1
The final step would be to add
answer = 91

Please help - 1/2 - 2/3v = 4/5
Answer and Step-by-step explanation:
First, let's convert all of the denominators to have the same denominator.
A common denominator 2, 3, and 5 share in common is 30.
((-1/2) * 15/15) + ((-2/3 v) * 10/10) = ((4/5) * 6/6)
-15/30 + -20/30v = 24/30
Add 15/30 to both sides.
-20/30v = 39/30
Multiply by -30/20 on both sides to get v.
v = [tex]-\frac{39}{20}[/tex] is the answer.
