Josie and Allanah are each saving money. Josie starts with 100$ per week in her savings account and adds 5$ per week. Allanah starts with 10$ in her savings account and adds 20$ each week. 1) Write equations to represent josie's savings and alana's saving.(you should have 2 different equations) After 4 weeks who has more money in their savings account? And after how many weeks will Josie and Allanah have the same amount of money in their savings account?
8
Answer:
Josie: 100 + 5x
Allanah: 10 + 20x
As stated in my last response, x means the unknown variable of the amount of times they will repeat the process. Now, given that the unknown variable is 4, just plug it into the equation.
Josie: 100 + 5(4)
Allanah: 10 + 20(4)
Josie: $120
Allanah: $90
Josie clearly has more money (by then the end of 4 weeks)
Now, for the last question,
Josie: 100 + 5x
Allanah: 10 + 20x
If we set these equations equal to each other, x will equal 6
100 + 5x = 10 + 20x
This means after 6 weeks they will have the same amount of money.

Estefania can run 3/4 of a race in 2/3 hour. How long will it take her to complete the entire race?
Answer:
3/4 x = 2/3

Answer:
The slope is 25 and the y-intercept is 100
Step-by-step explanation:
With linear equations (y = mx + b), m is always the slope, which, in this case, is 25. It could also be written as [tex]\frac{25}{1}[/tex], although it's not necessary here
B is always the y-intercept, which is 100 here
When graphing an inequality what two signs are a closed circle
Answer: When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to". Graph the solution set of: -3 < x < 4 The solution set for this problem will be all values that satisfy both -3 < x and x < 4.

Which geometric series results in a sum of -69,905 ?
A geometric series that results in a sum of -69,905 include the following: B. ∑ -1/5(4)^k.
How to calculate the sum of a geometric series?Also, the sum of a geometric series is given by this mathematical expression:
[tex]S=\frac{a_1(1-r^n)}{1-r}[/tex] or [tex]\sum^{n-1}_{k=0}a_1(q)^k[/tex]
Where:
aₙ or n represents the nth term of a geometric sequence.q or r represents the common ratio.a₁ represents the first term of a geometric sequence.When the common ratio r = 4, n = 10, and the first term (a₁) = -1/5, we have the following:
[tex]\sum^{10-1}_{k=10} \frac{-1}{5} (4)^{10} = -69,905[/tex]
In conclusion, a geometric series whose sum would result in a sum of -69,905 is given by the second expression.

What is the equation, in slope-intercept form, of the line parallel to y = 5x +2 that passes through the point with coordinates (-3,2)
Answer:
Slope - intercept form y = 5x+17
The equation of the parallel line to the given line is 5x-y +17=0
Step-by-step explanation:
Explanation
The equation of the straight line is y= 5x+2
5x - y +2=0
The equation of the straight line is 5x-y+2=0
Given that the point(-3,2)
The equation of the parallel line to the given line is
5x -y +k=0
5(-3) - 2+k=0
-15 -2 +k =0
-17 +k=0
k =17
The equation of the parallel line to the given line is 5x-y +17=0
Final answer:-
Slope - intercept form y = mx+c
Slope - intercept form y = 5x+17

At the fair concession stand, a drink costs $1.50, and a hot dog costs $2.75. If Jacob has $18 to spend on food, how many of each item can he buy?
3 drinks and 7 hot dogs
3 drinks and 5 hot dogs
2 drinks and 7 hot dogs
2 drinks and 5 hot dogs
Answer:
Answer is D (2 drinks and 5 hotdog's)
Step-by-step explanation: 1st answer is over as it is $19.25 for only the hotdogs. 2nd is $18.50 which is a little over. 3rd one is $22.25. And the forth one is $16.75 which is perfect because he cant buy anything else with the remainder of his money.
You can use trial and error for 3 drinks and 2 drinks and can see how many hot dogs are available for Jacob to buy in $18 budget.
Jacob, with $18 dollars for food, under given conditions, can buy:
Option D: 2 drinks and 5 hot dogs.
How to decide what amount of drinks and hot dogs are obtainable in given $18 budget?This can be modeled by mathematical expression with use of variables, and inequality.
Suppose that you can by [tex]x[/tex] drinks and [tex]y[/tex] hot dogs, then their amount should not exceed $18 and they should try to use that $18 as much as they can.
Since 1 drink costs $1.5 and 1 hot dog costs $2.75, thus,
[tex]1.5x + 2.75y \leq18[/tex]
Using trial and error for 2 and 3 drinks (we could've done fro 5 or 7 hot dogs too)For 2 drinks:
Since x = amount of drinks = 2, thus from the obtained inequality, we have:
[tex]1.5x + 2.75y \leq 18\\1.5 \times 2 + 2.75y \leq 18\\2.75y \leq 18 - 3\\y \leq \dfrac{15}{2.75}\\\\y \leq 5.555...\\y = 5[/tex]
We took y = 5 since it is closest integer less than 5.55... since we cannot buy drink or hot dog in decimal points generally and cannot spend more than $18
Thus, if Jacob buys 2 drinks, then he can by 5 hot dogs at max.
For 3 drinks:
Since drinks' amount increased, then hot dogs amount will have to decrease to keep them together under $18. And since in 2 drinks Jacob could by 5 hot dogs, thus, now he will have to buy less than 5 hot dogs, which are not given in options.
Thus,
Jacob, with $18 dollars for food, under given conditions, can buy:
Option D: 2 drinks and 5 hot dogs.

EASY BRAINLY/ POINTS!! PLEASE HELP
Answer: The answer would be x = 19/3, 5/3
Step-by-step explanation:
Since we are finding the x intercepts, we must set the equation to equate 0. So:
0 = 3 |x-4| - 7
Then, we want to simplify the right side so it is just the absolute value, so lets start by adding 7 to both sides.
0 = 3 |x-4| - 7
+7 +7
7= 3 |x-4|
Now we divide both sides by 3.
7= 3 |x-4|
3 3
7/3 = |x-4|
Now, due to the properties of absolute value, we must solve this twice, since absolute value always leads to a positive value, we want to set up one equation where 7/3 is positive and one where it is negative.
7/3 = x-4 -7/3 = x-4
add 4 to both sides
7/3 = x-4 -7/3 = x-4
+4 +4 +4 +4
Then, you get your two x values
x= 6.333... or 19/3 AND x = 1.66666 or 5/3

2x+4x+32x * 3 =6(2x+2x)+(3x+3)2x(2+x)+3(x+x)(2x+3)(2*x)James bought 3 pairs of shoes for $ 175.5. How much would he need to pay for 6 pairs of shoes?
[tex]175.50 \times 2 = 351.00[/tex]
He needs to pay $351.00 for 6 pairs of shoes.
Step-by-step explanation:
let's use ratio
3/ 175.5. as 6/X
cross multiply and solve for X
[tex] \frac{3 }{175.5} = \frac{6}{x} [/tex]
3X = 1053......divine both sides by 3 to solve for X
X = 351.
James would pay $351 for 6 pairs of shoes.
or you should have just multiply 175.5 by 2 because 6 pairs us the double of 3.
Which weighs more: a watermelon that weighs 7.5 kilograms or a baby that weighs 12
pounds? Explain your reasoning. Note: 1 pound is about 0.45 kilograms.
Answer:
A 12 pound baby is equivalent to 5.4kg, while a watermelon weighs 7.5kg, which is obviously larger than 5.4, so the watermelon weights more.
Step-by-step explanation:
To start off, we should convert the numbers in the same units. The question has told us that 1 pound is around 0.45kg. So let's do 12 * 0.45 which gives us 5.4kg. We already know that a watermelon weighs 7.5 kilograms, so from this we know that the watermelon weighs more.
