Answer:
substitution method is tricky until u get the hang of it. 6y=x so 3x-8y=-50 can be rewritten as 3(6y)-8y=-50.
Step-by-step explanation:
3x-8y=-50.........(1)
6y= x ..............(2)
Substituting x = 6y in (1)
3(6y) - 8y = -50
multiply 3(6y)
18y - 8y = -50
subtract 8y from 18y
10y = -50
divide to get y alone
y = -50/10
y = -5
now substitute. you know what y is. 6y=x / 6(-5)=x
solve :)
6y = x
6(-5) = x
-30 = x
x = -30

Brianna bought snacks for her team's practice. She bought a bag of oranges for $2.63 and an 8-pack of juice bottles. The total cost before tax was $16.07. Write and solve an equation that can be used to determine xx, how much each bottle of juice costs?
Answer:
$1.68
Step-by-step explanation:
The total cost is $16.07 and there was 2 things bought- the oranges and the juice bottles. to make it easier to find the cost of the juice bottles, we'll subtract the cost of the oranges (2.63) from the total (16.07), which gives us 13.44. this number represents the total cost of only the bottles. To find out the cost if each individual bottle, you need to divide the total (13.44) by the number of bottles (8). This gives us 1.68, so the cost of each bottel is $1.68
Answer: 1.68
Step-by-step explanation: It depends how your teacher thought how to solve this but the easiest way would be: 16.07 - 2.63 = 13.44 than 13.44 divided by 8= 1.68.

2x + y=120
x + y=70
Answer:
(50, 20)
Step-by-step explanation:
y = -2x + 120
x + (-2x+120) = 70
-x = -50
x = 50
y = -2x+120
y = -2(50)+120 = 20
{x,y} = {50,20}
Answer what you can please and show work. I will mark you brainliest.
Answer:
part 1:
1) AB = BC = 10
2) DE = sqrt(10² - 9²) = sqrt(19)
3) CED = 90⁰
4) BCD = (90⁰ - 53⁰).2 = 74⁰
part 2:
because FGHJ is a rhombus
=> GK = KJ
<=> 3x + 1 = x + 9
<=> 2x = 8
<=> x = 4
and we have:
GHK + FGK = 90⁰
<=> (4y - 8)/2 + y + 4 = 90⁰
<=> 2y - 4 + y + 4 = 90⁰
<=> 3y = 90⁰
<=> y = 30
5) with x = 4 => GJ = 2KJ = 2.(4 + 9) = 26
6) JK = 4 + 9 = 13
7) with y = 30, HFJ = 90 - FGK = 90 - 34 = 56⁰
8) HJF = 2.FGK = 2.34 = 68⁰
part 3:
because MNLO is rectangle
=> MP = PO
<=> 5a - 7 = 2a + 8
<=> 3a = 15
<=> a = 5
9) with a = 5, MO = 2.PO = 2.(2.5 + 8) = 2.18 = 36
10) NP = PO = 2.5 + 8 = 18
11) LM² = LN² - MN² = MO² - 26² = 36² - 26² = 620
=> LM = 2sqrt(156) = 24,9
12) tan NMO = NO/MN = LM/MN = 24.9/26
=> NMO = 43,8⁰
part 4:
because RSTU is square
=> SR = RU
=> 2k + 7 = 3k - 2
<=> k = 9
with k = 9 =>RU = SR = 2.9 + 7 = 25
13) RV = 1/2.SU = 1/2.sqrt(25² + 25²) = 17,7
14) SU = 2RV = 2.17,7 = 35,4
15) perimeter RSTU = 25.4 = 100
16) area RSTU = 25² = 625

Answer:
It can not be determined from the information given because the calorie sources are not independent.
Step-by-step explanation:
Explained in answer above.
There is no enough information to calculate the standard deviation of T.
Check below on how to determine the standard deviation
What is standard deviation?The standard deviation of a dataset is how much the data elements of the dataset are far from the mean or average value of the dataset
The given parameters are the mean and the standard deviations of calories from fat, protein, and carbohydrates
