PLEASE HELP

Answers

Answer 1

Answer:

150 lemon jellybeans

Step-by-step explanation:

Add the ratios up to get 12 lemon jelly beans out of 64 jellybeans.

[tex]\frac{12}{64} =\frac{x}{800}[/tex]

Cross multiply:

9600 = 64x

---> x = 150 lemon jellybeans

Answer: 85 m + 20

Step-by-step explanation:

Make fractions have same, common denominator. LCD = 40

9/10 = 36/40

2/5 = 16/40

3/1 = 120 / 40

[tex]\frac{35}{40}m+\frac{36}{40}-\frac{120}{40}m - \frac{16}{40}[/tex]

To solve the equation 34x=15, Abby multiplied both sides by ¾ and got a solution of x=1114. Explain the error that Abby made and then find the correct value of x.

Answers

Answer:

x = 20

Step-by-step explanation:

3/4x = 15

Abby's calculation:

3/4x = 15

Multiply both sides by 3/4

x = 1114

Abby's error was multiplying both sides by 3/4 instead of dividing both sides by 3/4 to get the value of x

Correct calculation:

3/4x = 15

Divide both sides by 3/4

3/4x ÷ 3/4 = 15 ÷ 3/4

x = 15 × 4/3

x = 60/3

x = 20

Check:

3/4x = 15

3/4*20

= (3*20) / 4

= 60/4

= 15

3/4*20 = 15

1 (part 2). For the following data set: 52, 54, 43, 48, 37, 51, 39, 41, what is the 5 Median?

Answers

Answer:

45.5

Step-by-step explanation:

First, you need to put the data in order: 37, 39, 41, 43, 48, 51, 52, 54

I'm not sure what 5 median means, but to find the median, you look for the middle number of the data set.

43 + 48 = 91

then, you divide the numbers by 2 to get the median.

91/2= 45.5

So, the median is 45.5
