Answer:
It's long but you use Substitution!
Step-by-step explanation:
Let's solve your system by substitution.
2x+3y=3750;4x+y=4250
Rewrite equations:
4x+y=4250;2x+3y=3750
Step: Solve 4x+y=4250 for y:
4x+y = 4250
4x+y+−4x = 4250+−4x (Add -4x to both sides)
y = −4x+4250
Step: Substitute −4x+4250 for y in 2x+3y = 3750:
2x+3y=3750
2x+3(−4x+4250)=3750
−10x+12750=3750 (Simplify both sides of the equation)
−10x+12750+−12750=3750+−12750 (Add -12750 to both sides)
−10x =−9000
−10x = −9000 (Divide both sides by -10)
−10 −10
x=900
Step: Substitute 900 for x in y = −4x+4250:
y=−4x+4250
y=(−4)(900)+4250
y=650 (Simplify both sides of the equation)
Answer:
x=900 and y=650
The length of a new rectangular playing field 4 yards longer than double the width. If the perimeter of the rectangular playing field is 344 yards, what are it’s dimensions?
Answer:
Hi There!
Your answer is:
Length = 116
Width = 56
Step-by-step explanation:
L= 4+ 2w
Width=w
perimeter formula
l+l+w+w= perimeter
Subsitute L for 4+2w
(4+2w)+(4+2w) + (w) + (w) = 344
8 +4w+w+w = 344
8+ 6w = 344
-8
6w = 336
/6
w= 56
PLUG BACK IN!
Length = 4+ 2w
Length = 4+ 2(56)
Length = 116
Width = 56
CHECK YOUR WORK
116+116+56+56= 344???
344 = 344 YES

The list below shows the number of magazines a bookstore sold each day during one week.
5, 6, 8, 9, 6, 10, 7
What is the median number of magazines sold during the week?
A. 6
B. 7
C. 9
D. 10
Answer:
7
Step-by-step explanation:
You have to but the numbers in order than you cross each of the ends until you get the middle number/median
Answer: 9
Step-by-step explanation:
The median in math is basicly the middle of the list. First, put the list in order from least to greatest. Then, find the middle. If there is no middle, add the two numbers in the middle. Add them together, and divide the sum by two. The quotient is the median.
In this case, there is a middle. The middle is nine. Nine is the median.

Write the equation of the line with the given point and slope.
(-5, -3); slope = -3/5
A line in point slope form is y = mx + b
m = the slope
b = y-intercept
So far our line looks like: y = -3/5x + b
Let's plug -5 into x and -3 into y to solve for b
-3 = -3/5(-5) + b
Let's multiply -5 by -3/5
-3 = 3 + b
Subtract 3 from both sides.
-6 = b
Our line is: y = -3/5x - 6

Phone company 1 offers a plan that costs 35.99 and includes unlimited texting, phone company 2 offers a plan that costs 19.99 and charges 0.25 per text
For what number of texts does the 2nd phone company plan cost more than the 1st phone company
Write and solve an inequality that models this situation. define your variables.
Answer:
at 65 texts , co 2 costs more
19.99 + .25x > 35.99
x= number of texts
Step-by-step explanation:
19.99 + .25x = 35.99
x= number of texts
.25x= 35.99-19.99
.25x=16
x=16÷.25

Raul and Ivan each make a number pattern, as described.
• Raul's pattern: start with 15, add 2
• Ivan's pattern: start with 11, add 3
What number in Raul's pattern and in Ivan's pattern is the same in a pair of corresponding terms?
(A) 17
(b) 21
(C) 23
(D) 26
23
26
Answer:
Option C. 23
Step-by-step explanation:
To know the correct answer to the question given above, let us determine the sequence of Raul and Ivan. This is illustrated below:
From the question given above,
Raul's pattern: start with 15, add 2
Ivan's pattern: start with 11, add 3
For Raul:
Raul's pattern: start with 15, add 2
1st term = 15
2nd term = 15 + 2 = 17
3rd term = 17 + 2 = 19
4th term = 19 + 2 = 21
5th term = 21 + 2 = 23
6th term = 23 + 2 = 25
For Ivan:
Ivan's pattern: start with 11, add 3
1st term = 11
2nd term = 11 + 3 = 14
3rd term = 14 + 3 = 17
4th term = 17 + 3 = 20
5th term = 20 + 3 = 23
6th term = 23 + 3 = 26
Summary
Term >>>>> Raul >>>>>> Ivan
1 >>>>>>>>> 15 >>>>>>>> 11
2 >>>>>>>>> 17 >>>>>>>> 14
3 >>>>>>>>> 19 >>>>>>>> 17
4 >>>>>>>>> 21 >>>>>>>> 20
5 >>>>>>>>> 23 >>>>>>>> 23
6 >>>>>>>>> 25 >>>>>>>> 26
From the calculations made above, we can see that in the 5th term, both Raul and Ivan has the same number as 23.

What is the measure of ZA degrees?
Answer:
Since this is an isosceles triangle, the angles opposite to the equal sides will also be equal
Therefore,
angle ABC = angle ACB
We are given that angle ACB is 30 degrees
Hence, angle ABC = 30 degrees
We know that according to the angle sum property, the sum of all interior angles of a triangle is 180 degrees
So, angle ABC + angle ACB + angle CAB = 180 degrees
replacing the variables with values we already know
30 + 30 + angle CAB = 180
angle CAB = 180 - 60
angle CAB = 120 degrees
Hence the measure of angle A is 120 degrees

Answer:
1. b 2. b
Step-by-step explanation:
1. In the graph it shows a negative slope so we can immediately eliminate a and c since they have a positive slope as shown in the equation. Then the initial value is the y coordinate when x is 0. In the graph you can see that when x is 0 y is 18 so the equation would be h= -3+18
2. In the problem it says that Jennifer is paid $2,200 as a base salary. This means that this is her initial value. Then you can see that she gets paid 300 extra for every car she sales. This is the rate of change. The equation will be y=300x+2,200
fyi 300 goes first because it is the rate of change and those always go first.

Answer:
GCF= 4 LCM=40
Step-by-step explanation:
Factors of 8:1,2,4,8
Factors of 20:1,2,4,5,10,20
Greatest common factor is 4 because it is the highest factor in both sets.
