Answer:
$23
Step-by-step explanation:
let j be jacob"s money
Then angie is 3j, and Erin is 3j+35 so 7I
=161
j=23
Answer: Erin - $104; Angie - $69; Jacob - $23.
(please give me brainlest ❤️)
Step-by-step explanation:
JACOB has least amount of money, so let's say that he has :
x amount of money
ANGIE has 3 times more than jacob:
Angie has 3x
ERIN has $35 more money than Angie:
3x+35
their money together is $196, that means if we add all of their money, it will be equivalent of 196:
3x+35+3x+x=196
now lets find x value.
put all the xes on right side and all known numbers on left side.
i think u know that when it goes to another side it changes sign; for example - makes + and × makes /
3x+35+3x+x=196
7x=161
x=161/7
x=23
now plug x values for each kid:
so Jacob had x=23
Angie had 3x=3×23=69
and Erin had 3x+35=69+35= 104
lets check our answer:
23+69+104=196
196=196
so sum of their money really gives us $196.

_____% of 300 plants is 195 plants
Answer:
65%
Step-by-step explanation:
3x+9=5x+21
What is x
Answer:
X = -6
1. 3x + 9 = 5x + 21
2. Subtract -5x from both sides
3x + 9 - 5x = 5x + 21 - 5x
3.-2x + 9 = 21
4. Subtract 9 from both sides
-2x + 9 - 9 = 21 - 9
5.-2x = 12
6. Divide both sides by -2
-2x/-2 = 12/-2
7. x= -6
A jazz concert brought in $119000 on the sale of tickets. If the tickets sold for and each, how many of each type of ticket were sold
Answer:
6850 & 650
Step-by-step explanation:
The question is partly incomplete as it didn't state the cost of ticket sold. Also, it didn't state the total number of tickets sold. But, assuming that the tickets sold were $15 and $25 tickets, and the total number of tickets sold was 7500, then we say that
Let x = the number of $15 tickets sold
Let y = the number of $25 tickets sold
x + y = 7500 y = 7500 - x
15x + 25y = 119000
15x + 25(7500-x) = 119000
15x + 187500 - 25x = 119000
-10x = -68500
x = 68500 / 10
x = 6850 tickets at $15 each
Remember from the first calculation, we said x + y = 7500, then
y = 7500 - 6850
y = 650 tickets at $25 each
All you have to do is substitute the values I assumed for your given value. Thanks

PLEASE ANSWER THIS QUESTION RIGHT Name the x-intercept(s)?
A:0 and 4,B:2,C:4,D:0.
Answer:
A. 0 and 4
Step-by-step explanation:
The x-intercepts are simply the values of x when y = 0. In other words it is the points where the line curve intercepts or cuts across the x-axis.
Form the graph given, we can see that at x = 0 and x = 4, the value of y = 0. Simply put, the curve cuts the x-axis at x = 0 and x = 4.
x-intercepts are 0 and 4.
The cost for Shania's groceries is $215. If the sales tax rate is 8%, how much will Shania pay for tax?
Answer:
The tax paid by shania is $17.2
Step-by-step explanation:
The computation of the tax paid by shania is as follows:
= Cost of the shania groceries × sales tax rate
= $215 × 8%
= $17.2
by multiplying the cost of the shania groceries with the sales tax rate we can measured the tax paid by shania
hence, the tax paid by shania is $17.2

In a random sample of 60 computers, the mean repair cost was $150. Assume the population standard deviation is $36. Construct a 95% confidence interval for the population mean.
Answer:
The 95% confidence interval for the population mean is between $140.89 and $159.11
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]
Now, find the margin of error M as such
[tex]M = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample. So
[tex]M = 1.96\frac{36}{\sqrt{60}} = 9.11[/tex]
The lower end of the interval is the sample mean subtracted by M. So it is $150 - $9.11 = $140.89
The upper end of the interval is the sample mean added to M. So it is $150 + $9.11 = $159.11
The 95% confidence interval for the population mean is between $140.89 and $159.11
Chau runs 10 miles in 58 minutes. How many minutes does he take per mile?
Answer:
Per mile Chau takes 5.8 minutes per mile.
Step-by-step explanation:
To find this answer you would have to do the amount of time divided by the amount of miles. Always remember when dividing time most of the time goes first unless the problem / instructions say differently. So, when you do 50 divided by 10 you will get 5.8. So, Chau takes 5.8 minutes per mile.

The District Commissioner levies a fine of 200 bags of cowries for the crime, yet the messengers collect 250 bags from the villagers. Why
Answer:
Extra 50 bags were collected by the messengers.
Step-by-step explanation:
a) Number of bags of cowries levied as fine by the District Commissioner = 200 bags
Number of bags of cowries collected by the messengers = 250 bags
The difference or extra bags collected above the authorized fine = 50 (250 - 200)
b) The extra 50 bags could be bribes collected by the messengers to settle their own selfish interests. They could also represent extras freely donated by the villagers for the messengers' trouble. In the colonial days, when literacy levels were very low among the indigenous peoples of Africa and white men were in charge of governance, it was established that the black "middlemen," called interpreters or messengers, greatly exploited their own people through inflated and wrongful interpretations of fines, contrary to what was levied by the District Commissioners (DCs).
