Answer:
One glass of milk: 15 carbs
One snack bar: 13 carbs
Step-by-step explanation:
This problem is an example of systems of linear equations. We can set this problem up by defining variable. I used [tex]m[/tex] for the glass of milk and [tex]b[/tex] for the snack bar.
First, we have: 4 glasses of milk and 2 snacks bar have a total of 86 carbs. We can write this as
[tex]4m+2b=86[/tex]
Next: 2 glasses of milk and 3 snack bars have a total of 69 carbs.
We can write this as
[tex]2m+3b=69[/tex]
Now we set it up.
[tex]4m+2b=86[/tex]
[tex]2m+3b=69[/tex]
By dividing both sides of the first equation by 2, we can use the subtraction method to get rid of the variable [tex]m[/tex]. Now we have
[tex]2m+b=43[/tex]
[tex]2m+3b=69[/tex]
Subtract like terms and solve for [tex]b[/tex]
[tex]-2b=-26[/tex]
[tex]b=13[/tex]
Now we substitute [tex]b[/tex] back into the original equation to find [tex]m[/tex].
[tex]2m+(13)=43[/tex]
[tex]2m=30[/tex]
[tex]m=15[/tex]
There you have it. I hope this helps!

Two lines A and B are parallel if both lines are rotated 90° in the same direction and then translated to the right by the same number of units which statement about the lines resulting from these transformations is true
Answer:
A' and B' will be parallel. (See Explanation)
Step-by-step explanation:
Given
Parallel lines: A and B
Rotation: 90° same direction
Translation: Right (same units)
Required
Describe the result of the transformation
No options were given. So, I will answer on general terms.
From the question, we can see that, the same transformation that was performed on line A was also done on line B.
This means that both lines will maintain the initial relationship between them.
Initially, A and B are parallel.
After the transformation, A' and B' will be parallel.
Answer:They will be the same line

Which algebraic expression represents the phrase "fourteen increased by a number"? 14 + y 14y StartFraction 14 over y EndFraction 14 minus y
The algebraic expression that represents the phrase "fourteen increased by a number" is 14 + y. which is the correct answer that would be an option (A).
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The given statement is "fourteen increased by a number"
According to the given question, translate the phrase into an algebraic expression:
⇒ 14 + y
This is because the phrase "increased by" means to add a certain number to 14.
The variable y represents the number that is being added to 14.
Thus, the algebraic expression that represents the phrase "fourteen increased by a number" is 14 + y.
Hence, the correct answer would be option (A).

A store has apples on sale for $21.00 for 6 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $126.00? Complete the explanation.
Answer:
115 apples
Step-by-step explanation:
6 pounds of apple = $21.00
Cost per pound :
$21.00 / 6 = $3.5 per Pound
1 pound = 16 ounces
16 ounces cost $3.5
1 ounce = $3.5 / 16 = $0.21875
5 ounces will cost :
5 * 0.21875 = $1.09375
Number of 5 ounce apple that can be purchased with $126
$126 / $1.09375
= 115.2
Approximately 115 apples

What is expression in mathematics?An expression in mathematics is a combination of terms both constants and variables.
Given are two labelled bars shown next to each other and each bar.
3 of the 8 bars are colored. Using fraction, we can represent it as -
{f} = 3/8
There are two such bars, so we can write -
y = 2{f}
y = 2 x 3/8
Therefore, the expression that is represented by the model below is -
y = 2 x 3/8.

What is the slope-intercept equation for the
graph shown below?
A. y = 1/2x - 1
B. y = -1/2x - 1
C. y = -1/2 + 1
D. y = 2x - 1
There are 99 males and 121 females participating in a marathon. What percent of the participants are female?
To do this, we first want to see how many participants there are in total by adding both males and females.
[tex]99+121=220[/tex]
Now we know that there were 220 total participants, but only 121 were females.
This allows us to set up the fraction 121/220= the percent female.
[tex]\frac{121}{220} =0.55[/tex]
or 55%
