two glasses of milk and 3 snack bars have a total of 78 carbohydrates (carbs), and 4 glasses of milk and 3 snack bars have a total of 96 carbs. Determine how many carbs are in one glass of milk and in one snack bar
Answer:
Each glass of milk is 9 carbs.
Each snack bar is 19.7 carbs.
Step-by-step explanation:
1. I know that 2 glasses of milk with 3 snack bars is 78 carbs.
The next part of the sentence has two times the amount of milk with the same amount of snack bars for 96 carbs.
Now, I will find the difference in the amount of carbs.
96 - 78 = 18 carbs.
So two glasses of milk = 18 carbs.
18 ÷ 2 = 9 carbs
So, each glass of milk is 9 carbs.
2. Since we know this, we can subtract the amount of carbs from the glasses of milk from the total amount of carbs.
78 - 19 = 59
In the first scenario, there are 59 carbs per 3 snack bars.
To find the amount of each snack bar, divide 59 by 3.
59 ÷ 3 = 19.7 when rounded to the nearest tenth.
Therefore, each snack bar is 19.7 carbs.
Answer:
glass of milk = 9 carbohydrates
snack bars = 20 carbohydrates
Step-by-step explanation:
Let s be snack bars and g be the glasses of milk.
3s + 2g = 78
3s + 4g = 96
-1(3s + 2g) = -1(78)
- 3s - 2g = - 78
- 3s - 2g = - 78
3s + 4g = 96
2g = 18
g = 18/2
g = 9
3s + 2g = 78
3s + 2(9) = 78
3s + 18 = 78
3s = 78 - 18
3s = 60
3s/3 = 60/3
s = 20
Check: g = 9; s = 20
3s + 2g = 78
3s + 4g = 96
3(20) + 2(9) = 78
60 + 18 = 78
78 = 78
3(20) + 4(9) = 96
60 + 36 = 96
96 = 96
So, the solution is g = 9; s = 20

If Jessica and Jonathan have created 19.64 cups of lemonade they sell the lemonade in serving of 1.25 cup. How many full serving will they be able to seel
Answer:
15 servings
Step-by-step explanation:
total amount of lemonade = 19.64 cups
lemonade per serving = 1.25 cups
total servings = 19.64 cups / 1 .25 cups = 15.712 servings
since you cannot sell a partially full serving, Jessica and Jonathan will only be able to sell 15 servings
in order for them to sell 16 full servings, they need to prepare 20 cups of lemonade (= 20 / 1.25 = 16)
Matthew invested $680 in an account paying an interest rate of 5.8% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 11 years?
Answer:
Step-by-step explanation:
1290
Based on the amount invested, the rate, and the period of compounding, after 11 years, the account would be $1,290.
As the rate is compounded daily, the rate and the period need to be converted to daily figures:
Rate = 5.8% / 365 days = 5.8/365 %
Period = 11 x 365 = 4,015 days
The amount in 11 years is:
= Amount x ( 1 + rate) ^ period
= 680 x (1 + 5.8/365%) ⁴⁰¹⁵
= $1,286.965
= $1,290
In conclusion, the account would have $1,290.

y = b + 5x
(10,1)
Solve for b. Brainliest!
Answer:-49
Step-by-step explanation:(10,1)= (x,y) so we can see that x=10 and y=1. Now you put them in the equation 1=b+5*10. Then you get 1=b+50 and you put 50 to the left side and it becomes negative. 1-50=b . Therefore b=-49
Answer:
Step-by-step explanation:
y = 5x + b ⇒ b = y - 5x
(10, 1)
b = 1 - 5(10) = 1 - 50 = - 49
b = - 49

Find the possible values of x. The perimeter is less than 28 feet. The sides of the triangle are labeled 7 feet, 7 feet, and x. The possible values of x are
The possible values of x are positive integers that are less than 14
The perimeter of a figure is the sum of all its sides.
A triangle has 3 sides. The length of the 2 sides are given. The third side is x . Therefore,
perimeter = 7 + 7 + x
perimeter < 28 feet
Therefore,
7 + 7 + x < 28
14 + x < 28
subtract 14 from both sides
14 - 14 + x < 28 - 14
x < 14
Therefore, the possible value of x are positive integers that are less than 14.

Quadrilateral ABCD has coordinated A(-4,3)B(-3,6)C(0,8)D(-2,5). Prove that quadrilateral ABCD is a parallelogram.
Answer:
The plotted dots connect to create a parallelogram with two sets of parallel lines in the second quadrant
Step-by-step explanation:
This might be a little tricky to explain but I will try my best.
A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel.
The first pair of numbers is in the second quadrant the second set is also in the second quadrant a little bit up and to the right. The third set in the line a little up, the last set is again in the second quadrant and a little further down and near the middle.
Sorry if the answer isn't what you had hoped for, feel free to ask questions about it and I'll explain the best I can.
