The ratio of boys to girls at a soccer camp is 3:5. If there are 51 boys at the camp, then how many of the campers are girls? HINT: Solve using a proportion.
:} thank uuu

Answers

Answer 1

Answer:

85 girls

Step-by-step explanation:

A proportion of 3:5 means that there are 5 girls at the camp for every 3 boys.

You can find the number of girls by taking the amount of boys and multiplying by the proportion.

51 * 5:3

51 * 5/3

85 girls

Answer 2
85 girls and 51 boys together it’s 136 children at the soccer camp

Answer:

x>-4

Step-by-step explanation:

The answer would be x>-4 because an open circle is greater than or less than; in this case, the arrow is pointing toward the right.

Answer: it would be the last one

letter C

Step-by-step explanation:

Find the slope of the line given its graph.

Answers

Slope = Rise/Run
Using the two points, rise (y) = 4 and run (x) = 2, so the slope is 2.

You can also use the slope formula:
(Y2 - Y1)/(X2 - X1)
Rise over run so it’s 4 over 2 the 4 is the rise (y)
And the 2 is the run (x)
You can simplify 4/2 with 2 so you just divide 4 divided by 2 which is 2
Then 2 divided by 2 is 1

Which then gives you 2/1 which is just 2
So the answer is 2

Answer:top one is a

second one is c

nuber 3 is c

4 is b

Step-by-step explanation:

Answer:

1. x >= 4

2. x /= -4

3. The first one

4. The second one

Step-by-step explanation:

1. Since the bolded arrow is pointing to numbers greater than 4, we can tell that x is greater than 4. The dot on the number 4 is colored, meaning that four is included, thus x is greater than or equal to 4.

2. Since the bolded areas are on every point on the graph except -4, we can tell that x is every number but -4, thus x is not equal to -4.

3. The sign "<" indicates that x is less than 3. This eliminates the second option. Since there is no equal to sign, the dot isn't colored, thus, the first one.

4. The sign "<=" indicates that x is less than or equal to -1, eliminating the third option. Since it is equal to, the dot should be colored, thus, the second one.

I’m pretty sure it would just be 5x for AB and x for EF

i will give brainiest please help me <3

Answers

Answer:The lengths of AB and EF are 10 and 2 respectively

If the triangle ABC and DEF are similar, based on the similarity theorem of a triangle;

AB/DE = BC/EF

5x/4 = 5/x

5x² = 20

x² = 20/5

x² = 4

x = 2

Since the value of x is 2, length of AB is 5x = 5(2) = 10

Since EF = x, hence EF = 2

The lengths of AB and EF are 10 and 2 respectively

Step-by-step explanation:

Jamie buys 3 snacks and 2 bottles of juice. Each snack costs $0.75, and each bottle of juice costs j dollars. The total cost of the snacks and bottles of juice is $6.75. Which of the following equations could be used to find the cost of a bottle of juice, in dollars?

Answers

Answer:

2.25+2j=6.75

That is the answer I got

Answer is 3(.75) + 2j = $6.75 is the equation

Step by step

Since you didn’t give options I will give you my equation.

3 snacks * .75 + 2 juice * x unknown $ = 6.75

3(.75) + 2j = $6.75 is the equation

Solve

2.25 + 2j = 6.75

Subtract 2.25 from both sides to isolate j

2.25 - 2.25 + 2j = 6.75 - 2.25

2j = 4.50

Divide both sides by 2 to solve for j

j = $2.25

Given the inequality 5(n − 4) < 4(n + 15), determine which integer makes the inequality false.

S:{80}
S:{15}
S:{5}
S:{−9}

Answers

Answer:

-9

Step-by-step explanation:

5(-9-4)

5(-13)

-65

4(-9+15)

4(6)

24

-65<24 so -9 is false because -65 is not smaller than 24

The solution is Option A.

The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is given by

5 ( n − 4 ) < 4 ( n + 15 )

Now , on substituting the value of n as 80 in the inequality equation , we get

5 ( n − 4 ) < 4 ( n + 15 )

when n = 80

5 ( 80 - 4 ) < 4 ( 80 + 15 )

5 ( 76 ) < 4 ( 95 )

380 = 380

So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80

Hence ,

The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

Jane is saving money to buy a game. The game costs $20, and so far she has saved four-fifths of this cost. How much money has Jane saved?

Answers

Answer:

she has 16$ saved

Step-by-step explanation:

20 divided 5 = 4

4 fifths of 20 is 16

Answer: $16

To do this problem you need to first find out how much 1/5th of 20 is. Which we can do by multiplying 20 x 1/5 which will give us 4. Since $4 is 1/5 of the total amount and we need 4/5th this value, we can multiply 4 x 4 to get $16 saved in total.
