with Judy jogging north and Jackie jogging west (on straight roads). When Jackie is 1 mile farther fro m the intersection than J
miskamm [114]
Let the distance of Judy from intersection is x and distance of Jackie from intersection is y.

We convert the given information to equations, step by step.

Point 1: When Jackie is 1 mile farther from the intersection than Judy.

This means y is 1 mile more than x.

So,

y = 1 + x

Point 2: The distance between them is 2 miles more than Judy’s distance from the intersection. 

Distance between is x+ y.

So, x+y is 2 miles more than y.

x+y = y + 2
⇒
x = 2

From point 1 we have:

y = 1 + x = 1+ 2 = 3

So,

Distance of Judy from intersection is 2 miles and distance of Jackie from intersection is 3 miles.

What is the value of x?
rewona [7]

Vertical angles are equal

so

4x + 7 = 5(x - 4)

4x + 7 = 5x - 20

5x - 4x = 7 + 20

x = 27

Answer:

Hi dear, let's solve it

Step-by-step explanation:

step A: x + (3x-1) + 5x = 180

➡️ x+3x-1+5x=180➡️9x-1=180

9x=180+1➡️9x=181➡️x=181÷9➡️x≈20.1

A angle: 20.1

B angle: 59.3

C angle: 100.5

NISA [10]

Answer:

a

Step-by-step explanation:

Here is the question used in answering this question :

Gio weighed five boxes before he shipped them. The weights were: 52,48,48,54, and 50. Which statement is true?

A) The mode is equal to the minimum

B)  The mode is greater than the mean

C)  The median and mode are equal

D) The mean is less than the medium

Mode is the number that occurs the most. that number is 48.

Mean = sum of numbers / n = 52 + 48 + 48 + 54 + 50  / 5 = 50.4

Median is the middle number

Arranging the numbers in ascending order : 48, 48. 50, 52, 54. The median is 50

the mode is 48 which is equal to the minimum

the mean is greater than the mode

the mode and median are different figures
