Answer:

= 195y + 130

Step-by-step explanation:

Apply the distributive law a(b + c) =ab + ac

$65\left(3y+2\right)=65\cdot \:3y+65\cdot \:2\\=65\cdot \:3y+65\cdot \:2$

Simplify:

$65*3y+65*2\\195y+130$

frez [133]

In solving this type of problem always look for the person you don't have any information about in this case it's Eve therefore Eve is X, Justin has $7.50 more than Eve, therefore
X+$7.50 is Justin and Emma has $12 less than Justin, therefore subtract $12 from Justin X+$7.50-$12, since the total amount is $63 add all the numbers and equal them to $63.
x+7+x+7.5-12+ x=63
3x+3=63
3x=60
x=20
Plug in the x for each person
therefore Eve=$20
Justin=$20+$7.50= $27.50
Emma has $12 less than Justin therefore $15.50
Add all the money and it equals $63

A taxi fare has a fixed charge of $1.75 and an additional charge $0.45 per mile. A fare for m miles is $13.90. Which equation co

Anestetic [448]

Answer:

B) 1.75 + 0.45m = 13.90

Step-by-step explanation:

To calculate the Taxi fare, we need to sum the fixed charge and the additional charge. Fixed charge ever is $1.75. The additional charge changes with the miles traveled (one mile costs $0.45, two miles $0.90, and so on), so we need multiply the charge ($0.45) by the miles m traveled.

1.75 + 0.45 m

The problem says that the fare was equals to $13.90 so the final equation is

1.75 + 0.45m = 13.90

user100 [1]

Answer:

This is required solution

Step-by-step explanation:

Given that:

for male

joy = 28

happiness = 20

love = 40

anger = 18

a] we need to calculate the percentage of emotions for the male

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{28}{106}\times100$

percentage of joy = 26.41

percentage of happiness = $\dfrac{20}{106}\times100$

percentage of happiness = 18.86

percentage of love = $\dfrac{40}{106}\times100$

percentage of love = 37.73

percentage of anger = $\dfrac{18}{106}\times100$

percentage of anger = 16.98

for female

joy = 61

happiness = 25

love = 80

anger = 60

we need to calculate the percentage of emotions for the female

using formula for percentage

$\percentage\ of\ emotions=\dfrac{emotion}{total\ emotions}\times100$

percentage of joy = $\dfrac{61}{226}\times100$

percentage of joy = 26.99

percentage of happiness = $\dfrac{25}{226}\times100$

percentage of happiness = 11.06

percentage of love = $\dfrac{80}{226}\times100$

percentage of love = 35.39

percentage of anger = $\dfrac{60}{226}\times100$

percentage of anger = 26.54

B] We need to draw a bar graph for male and female

using percentage of emotion of male and female

according to using percentage we draw a bar graph using data of part A.

Hence, this is required solution

The sum of two numbers that differ by 3 is x, what is the value of the greater of the two numbers?

jolli1 [7]

Answer:

Step-by-step explanation:

You really don't have enough information to solve this with one answer. You want a value for y and there is no what to limit it to just 1 set of values. For example if x = 23 then

x = y + y - 3

x = 2y - 3

23 = 2y - 3 Add three to both sides

23+3 = 2y Combine

26 = 2y Divide by 2

26/2 = 2y/2 Do the division

13 = y

The smaller number is 13 - 3 = 10

Their sum is 13 + 10=23 But that answer is not unique.

====================

Suppose x = 13

13 = 2y - 3 Add 3

13 + 3 = 2y

16 = 2y

y =8

The larger number = 8

The smaller number = 5

=======================

The best I can do is give you the equation which is

x = 2y - 3
