Answer: Below
Step-by-step explanation:
Using the information, we can see that they all refer to Elena as a marker for how much they walked, directly or indirectly.
Let's use E for Elena, J for Jada, and L for Lin.
E + 4 = J
E + 6 = L
E = E
We know they all walked a total of 37 miles.
J + L + E = 37
(E + 4) + (E + 6) + E = 37
Simplify.
3E + 10 = 37
3E = 27
E = 9
Using E is 9, we find that:
Elena walked 9 miles
Lin walked 15 miles
Jana walked 13 miles
13 + 15 + 9 = 37, so our answer checks out.
We know that:
[tex]Jada + Elena + Lin = 37 \space\ miles[/tex][tex]Jada = 4 + Elena[/tex][tex]Lin = 2 + Jada[/tex]Finding the distance each walked:[tex]Jada + Elena + Lin = 37 \space\ miles[/tex]Add 4 both sides
=> [tex]Jada + Elena + 4 + Lin = 37 + 4[/tex]=> [tex]Jada + Jada + Lin = 41 \space\ miles[/tex] [tex][Jada = 4 + Elena][/tex]=> [tex]Jada + Jada + Jada + 2 = 41 \space\ miles[/tex] [tex][Lin = Jada + 2][/tex]Changing "Jada + Jada + Jada" to "3(Jada)"
=> [tex]3(Jada) + 2 = 41 \space\ miles[/tex]Subtracting 2 both sides:
=> [tex]3(Jada) = 41 - 2[/tex]=> [tex]3(Jada) = 39 \space\ miles[/tex]Divide 3 both sides:
=> [tex]3(Jada) = 39 \space\ miles[/tex]=> [tex]\frac{3(Jada)}{3} = \frac{39 \space\ miles}{3}[/tex]=> [tex]\bold{Jada} = \bold{13 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Jada = 4 + Elena"
[tex]Jada = 4 + Elena[/tex]=> [tex]13 = 4 + Elena[/tex]Subtract 4 both sides:
=> [tex]13 - 4 = 4 - 4 + Elena[/tex]=> [tex]\bold{Elena} = \bold{9 \space\ miles}[/tex]Substituting the miles Jada walked into the equation "Lin = 2 + Jada"
=> [tex]Lin = 2 + 13[/tex]=> [tex]\bold{Lin} = \bold{15 \space\ miles}[/tex]

Answers
Answer:
22 shirts
Step-by-step explanation:
To find out how many shirts Ms. Li has in total, we have to set up a proportion.
[tex]\frac{8}{11} =\frac{16}{x}[/tex].As you can see, we multiply eight by two to get to sixteen. Whatever we do on the numerators, we must do to the denominators. Thus, eleven multiplied by two is twenty-two t-shirts.

In one day, Joe consumes 530 calories by drinking 1 serving of juice, 2 servings of milk, and 1 soda. Darius consumes 370 calories by drinking 2 servings of juice and 1 serving of milk. Marian consumes 510 calories by drinking 3 servings of milk and 1 soda. Using matrices to solve, how many calories are in 1 serving of milk?
A. 90
B. 110
C. 130
D. 180
Answers
Answer:
the answer is B on ed2020
Step-by-step explanation:
for answer b, if you subtract 330 from 510 you get soda = 180 cal. then if you subtract 110 from 370 you get 260, and 260 divided by two (he consumed 2 juice) equals 130.
so you have soda = 180 cal and juice = 130 cal
if you plug it into joe's calorie intake you do 130 (1 serving of juice) + 180 (1 serving of soda) and + 220 (two servings of milk) you get 530 which is joe's total calorie intake in liquids, so B (110) is correct
Using matrices to solve, the number of calories that are in 1 serving of milk is; 110 Calories
How to solve Linear Programming problems?
Let the calories in one serving of milk be x
Let the calories in one serving of juice be y
Let the calories in one serving of soda be z
Thus, for Joe, equation to show amount of calories is;;
2x + y + z = 530 -----(1)
For Darius, equation to show amount of calories is; ;
x + 2y = 370 ------(2)
For Marian, equation to show amount of calories is;
3x + z = 510 ------(3)
Using matrix calculator online to calculate this 3 equations, we have;
x = 110 calories.

Zoe filed for bankruptcy several years ago and now wants to take out a loan for $15,200. since zoe has a past bankruptcy, she will end up paying a higher interest rate. the loan term is four years, and her payments are $819.20 per month. with a better credit rating, her payments could have been $440.82 per month. how much more in interest will zoe end up paying for her loan because of her bankruptcy? a. $4,540.56 b. $15,135.20 c. $23,346.24 d. $18,162.24

18,162.24 / D
Step-by-step explanation:
12 months per year times 4 years is 48 months
819.20 x 48 = 39,321.60 which is what she is paying
440.82 x 42 = 21,159.36 which is what she could be paying
so do 39321.60 - 21159.36 to get 18,162.24 or answer D.

Answer: 6x+3y=12
x=-1/2y+2
Step-by-step explanation:
step 1: add -3y to both sides
6x+3y+-3y=12+-3y
6x=-3y+12
step 2: divide both sides by 6
6x/6=-3y+12/6
Answer:
y = 6 and x = -1.
Step-by-step explanation:
It's normally useful for me to rewrite the equation so they match. I'm using the substitution method.
First find out what "y" equals (I'm using the second equation):
Add 8 to both sides:
y - 8 = 2x
+8 +8
y = 2x + 8
Plug this into the previous equation.
6x + 3(2x + 8) = 12
Distribute first:
3(2x + 8)
3 * 2x = 6x
3 * 8 = 24
6x + 24
Rewrite the equation:
6x + 6x + 24 = 12
Find liked terms.
6x + 6x + 24 = 12
They are liked terms so combined them: 6x + 6x = 12x.
Rewrite the equation again:
12x + 24 = 12
Solve for "x".
Subtract 24 on both sides.
12x + 24 = 12
-24 -24
12x = -12
Divide 12 to get x by itself.
12x = -12
12
x = -1
Plug x into the second equation to find y.
y - 8 = 2(-1)
y - 8 = -2
Add 8 to both sides.
y - 8 = -2
+8 +8
y = 6
The answers are y = 6 and x = -1.
