Three sisters are saving for a special trip . The ratio of Nora's savings to Helga's savings is 8:3 and the ratio of Helga's savings to Maurice's savings is 3:4. Together all 3 have saved $60. How much has each saved?
Answer:
X = 10.588
Y = 28.2
Z = 21.176
Step-by-step explanation:
Consider Nova savings as X
Helga is Y
Maurice is Z
As per first ratio we conclude 8X=3Y
Second ratio we conclude 3Y = 4Z
We deduce 8X = 4Z
Last sentence => X+Y+Z=60 multiple it by 3
=> 3X + 3Y + 3Z= 180 but 8X = 4Y
=> 3X + 8X + 3Z =180 => 11X + 3Z=180 multiple the equation by 4/3
44/3 X + 4Z = 240 but 4Z = 8X
=> 44/3 X + 8 X = 240
=> 68/3 X = 240
=> 68X = 720
=> X =10.588
And Y=8/3 X =28.2
And Z=3/4 Y = 21.176

A sum of two mixed numbers is given.
What is the missing number?
Answer:
16.
Step-by-step explanation:
The whole numbers stay the same so it stays as 2. The way they get 30 for the denominator is by multiplying the fraction 1/3 by 10 and 1/5 by 6. So now we have 10/30 and 6/30. Add them together, 10+6=16
After spending many hours studying for your math class, you decide to reward yourself with a case of cream soda. Unfortunately, Corner Market only had a warm case left. You buy several bags of ice and decide to chill it at home. When you get home, the temperature of the soda is 76° F, and you proceed to pack it in ice. After 10 minutes, the temperature cooled to 70° F. If cream soda is best served at 60° F or cooler, how much longer must you wait to enjoy your chilled cream soda?

Total number of adults in the survey = 150
Number of women = 80
Number of men = 150 - 80
= 70
Ratio of men : women = 70 : 80
= 70 /80
= 7 / 8
= 7 : 8

Answer:
[tex]7[/tex]
Step-by-step explanation:
This means that there are 20 terms in between 11 and 31
[tex]31-11=20[/tex]
Since we know that the [tex]11th[/tex] term is [tex]29[/tex] and the [tex]31st[/tex] term is [tex]169[/tex], you can subtract the two to find out the values in between
[tex]169-29=140[/tex]
Now all we have to do is divide the values in between by the number of terms to find the common difference.
[tex]\frac{140}{20} =7[/tex]
Therefore the common difference is [tex]7[/tex]

Step-by-step explanation:
tomas works for a cellphone company. he has a base salary of $350 each month and earns an additional $40 for each cellphone he sells. write a function (linear equation) in slope-intercept form (y = mx + b) that represents tomas' total earnings (y) for one month for selling (x) number of cellphones.
Use the linear equation from question 1 to determine Tomas' earnings for a month where he sold 30 cellphones. *
Answer:
The function is [tex]y = 40x + 350[/tex]
When he sold 30 cellphones, he earned $1550.
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope(how much y changes when x changes by 1), and b is the y-intercept, that is, the value of w when x = 0.
Base salary of $350 each month and earns an additional $40 for each cellphone he sells.
If he sells 0 cellphones, he earns $350, so [tex]b = 350[/tex].
For each cellphone he sells, he earns $40, so [tex]m = 40[/tex]
The function is:
[tex]y = mx + b = 40x + 350[/tex]
Tomas' earnings for a month where he sold 30 cellphones.
This is y when [tex]x = 30[/tex]. So
[tex]y = 40*30 + 350 = 1550[/tex]
When he sold 30 cellphones, he earned $1550.

solve this system using elimination. 3x - 4y = -5, -10x + 4 = 12
Answer:
x = -4/5, y = 13/20
Step-by-step explanation:
-10x + 4 = 12
-10x = 8
x = -4/5
3x - 4y = -5
3(-4/5) - 4y = -5
-12/5 - 4y = -5
-4y = -13/5
y = 13/20
Double check:
3x - 4y = -5
3(-4/5) - 4(13/20) = -5
-12/5 - 13 = -5 (true)
solve the equation 3x+4=20

4 times 3 = 12
5 times 3 = 15
2 times 3 = 6
1 times 3 = 3

(c) x= 1
Step-by-step explanation:
(a) (b) (c)

x−3=4/2 2x+1= − 5/3 d^1−1
x−3=2 2x= -5/3-3/3 d^0
x=2+3 2x= -5-3/3 x=1
