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:

Answer:
51,000
Step-by-step explanation:
50,000
20% raise is
50,000 + 50,000 * 20/100
= 50,000 + 10,000
= 60,000
15% tax is
60,000 * 15/100
= 9000
so total money is 60000 - 9000
= 51000

A, B, C and D are four towns. B is 30 kilometres due east of A. C is due 30 kilometres north of A. D is due 45 kilometres due south of B. Calculate the bearing of D from B
ONLY ANSWER QUESTION B PLEASE
Giving lots of points
I will give brainlist
NO FRAUDS
Answer:
213.7°
Step-by-step explanation:
The bearing of B from D is angle ADB, Thus, ∠ADB = arctan(30/45) ≈ 33.7°
The bearing of D from B is that angle plus 180°, Thus, 180° +33.7° = 213.7°
-----------------------------------------------------------------------------------------------------------
Part A: 135
Part B: 213.7

[RevyBreeze]
MATE!
213.7°
The bearing of B from D is angle ADB, Thus, ∠ADB = arctan(30/45) ≈ 33.7°
The bearing of D from B is that angle plus 180°, Thus, 180° +33.7° = 213.7°
Part A: 135

Pamela's age is two times Jiri's age. The sum of their ages is 33. What is Jiri's age?
please please help
Answer:
Let Jiri's age be as 'x'
Therefore, Pamela's would be 2x
Since the addition of both is 72, the equation formed would be..
2x+ x =72
3x =72
x= 72÷3
x = 24 years.
Therefore, Jiri's age is 24 and Pamela's is twice of Jiri ie 48 years.

8.2x + 9y + 2(2.5x) + 10xy
plz Help
Answer:
13.2x + 9x + 10xyStep-by-step explanation:
=> 8.2x + 9y + 2(2.5x) + 10xy
=> 8.2x + 9y + 5x+ 10xy
=> 13.2x + 9y + 10xy
Since we can't simplify it from here, 13.2x + 9y + 10xy is our answer.
Determine the error(s) in the problem below and use mathematical language
from module 2 to explain and answer correctly.
Step-by-step explanation:
error is in ∆ABC =~ ∆RST
because it is,
∆ABC =~ ∆RTS or ∆STR
because,
AB = RT
BC = TS
CA = SR
hope this answer helps you dear! take care.
The error is in labelling the triangles.
What are triangles?A triangle is a polygon with three sides having three vertices. The angle formed inside the triangle is equal to 180 degrees.
Given are two ABC and RST
Since, Δ ABC ≅ Δ RST
That gives,
AB = RS
BC = TS
CA = RT
In figure,
AC has been equated to RS, which is wrong or incorrect because the corresponding side of AC is RT
The correct labelling will be
AB = RS = 5
BC = TS = 5
CA = RT = 5.5
Hence, The error is in labelling the triangles.

Answer:
Step-by-step explanation:
Convert the exponential equation to a logarithmic equation using the logarithm base
( 5 ) of the left side ( 25 ) equals the exponent ( 2 ) . log 5 ( 25 ) = 2
Use the definition of a logarithm,
log b ( x ) = y ⟹ b y = x , to convert from the logarithmic form to the exponential form.
