The system of equations that can be used to model the situation is:
B. [tex]x + y = 27[/tex][tex]y = 3 + \frac{1}{2}x[/tex]What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable x: number of boxes Juan packed.Variable y: number of boxes David packed.Together they packed 27 boxes, hence:
[tex]x + y = 27[/tex]
David packed 3 more than half the number Juan packed, hence:
[tex]y = 3 + \frac{1}{2}x[/tex]
Hence, the system of equations that models the situation is:

i’m stuck on this
Answers
Answer:
24 ?
Step-by-step explanation:
I may be wrong but I believe the answer is 24 since she lost half of her CDs a week later. The number 6 is not important to the word problem as the only information we need in the amount she has left and the amount she lost. I may be wrong so please check the work again?
Answer:
18 CDs
Step-by-step explanation:
To find how many she started with, It says she lost half, meaning she had must have had 24. Because 12 is half of 12. If she lost half of 24, she would have 12 left. Before she bought 24, she had 6 less, because she bought meaning plus, 6. But to get the beggining, you do the oppisite, which is minus 6. So, 24-6 to get 18.
To make sure we are correct plug in 18. She starts out with 18. She buys, 6. So plus 6. 18+6 to get 24. But she then a week later lost half, leaving her with 12 CDs. By seeing this, we can tell, she did in fact, have 18 CDs to start out.
P.S wow she must really be dum b to lose an entire an entire 12 CDs in a couple hours.
What is the measure of angle f
Answers
Answer:
48°
Step-by-step explanation:
1) The sum of the interior of any triangle is 180°. a + b + c = 180°. We need to find the value of x first before finding the angle F.
2) Substitute the values into a + b + c = 180, where [tex]a=6x-4[/tex], [tex]b =5x-7[/tex], [tex]c=8x-18[/tex].
Hence,
[tex]6x-4+5x-7+8x-18=180\\19x-29=180\\19x=180+29\\19x=209\\x=\frac{209}{19} \\x=11[/tex]
3) Find the angle of F by substituting 11 into x.
[tex]=5(11)-7\\=55-7\\=48[/tex]
Therefore, angle F has a measure of 48°.

what is the value of x that makes this equation true 3/4 + x = 1/8
Answers
The correct value of ''n'' in this equation will be -5/8.
Step-by-step explanation:To solve this equation, we're going to isolate ''x'', and then we're going to subtract the two fractions.
But to subtract the two fractions with different denominators, let's represent the fractions with the least common multiple of the denominators, being 8.
Resolution:[tex]\large \sf \dfrac{3}{4} +x=\dfrac{1}{8}[/tex]
[tex]\large \sf x= \dfrac{1}{8} -\dfrac{3}{4}[/tex]
[tex]\large \sf x= \dfrac{1-6}{8}[/tex]
[tex]\large \sf x= \dfrac{-5}{8}[/tex]
[tex]\boxed{\boxed{{\large \sf x=-\dfrac{5}{8} }}}[/tex]
So we can conclude that the value of ''x'' in this equation will be -5/8.

what year was it, exactly 4 centuries before 1965?
Answers
Based on the number of years in a century, we can calculate that the 4 centuries before 1965 was 1565.
A century refers to a period of 100 years.
If we are looking for a period of 4 centuries therefore, this would be:
= 4 x 100
= 400 years
4 centuries before 1965 would therefore be:
= 1965 - 400
= 1565
In conclusion, the answer is 1565.

What is (-1/2) in mathematics
Answers
Answer: One half is the irreducible fraction resulting from dividing one by two (2) or the fraction ... One half often appears in mathematical equations, recipes, measurements
Step-by-step explanation: For example, if you wish to halve the fraction 5/7, write “* 2” beside the denominator “7.” There is no operation to perform to the numerator. Multiply the denominator by 2 to halve the fraction. Using the same example, 7 * 2 = 14. This means that half of 5/7 is 5/14.
