Terms/CoefficientsCoordinates (x, y)Solving systems of equations using systemsStep-by-step explanation:
Step 1: Define Systems
x + 4y = 4
-x + 2y = 8
Step 2: Rewrite Systems
x + 4y = 4
[Subtraction Property of Equality] Subtract 4y on both sides: x = 4 - 4yStep 3: Redefine Systems
x = 4 - 4y
-x + 2y = 8
Step 4: Solve for y
Substitution
Substitute in x: -(4 - 4y) + 2y = 8[Distributive Property] Distribute negative: -4 + 4y + 2y = 8Combine like terms: -4 + 6y = 8[Addition Property of Equality] Add 4 on both sides: 6y = 12[Division Property of Equality] Divide 6 on both sides: y = 2Step 5: Solve for x
Define original equation: x + 4y = 4Substitute in y: x + 4(2) = 4Multiply: x + 8 = 4[Subtraction Property of Equality] Subtract 8 on both sides: x = -4On a triangle, one side measures 4x2−2x and another side measures 2x2 −5x+1. If the perimeter of the triangle is 9x2 + x+6, what is the measure of the third side of the triangle? (Your answer will be an expression)
Answers
Answer:
3x² + 8x + 5
Step-by-step explanation:
Subtract the sum of the 2 given sides from the perimeter, that is
9x² + x + 6 - (4x² - 2x + 2x² - 5x + 1)
= 9x² + x + 6 - (6x² - 7x + 1 ) ← distribute parenthesis by - 1
= 9x² + x + 6 - 6x² + 7x - 1 ← collect like terms
= 9x² + 8x + 5

Oliver, Lily, and Ella are hoping to save money. Oliver thinks saving money in a shoe box in his closet every month is a good idea. He decides to start with $150, and then save $75 each month. Lily was given $4000 from her Great Uncle Merv, and decides to put the money into an account that has a 7% interest rate that is compounded annually. Ella has earned $4500 working at the gas station and decides to put her money in the bank in an account that has a 7.5% interest rate that is compounded continuously.
the question is Describe the type of equation that models Ella’s situation. Create that equation of Ella’s situation. Using the equation you created, how much money will be in Ella’s account after 2 years? 10 years?
Answers
You'd first have to divide the first to, then add an divide your sume by the percent to get your answer.
Answer:
Step-by-step explanation:
Use formulaic methods. Since she has interest on her money, we have to include it:
i = log(x-4*7)^k
i is the interested amount, x is the variable we use, and k is the number of times. 7 is the interest
i = log(4000-4x7)^2 for 4000 at 7% interest over 2 years
i = log(4000-4x7)^10 for 4000 at 7% interest over 10 years
Amount after 2 years: $30,000
Amount after 10 years: $15,671
Chad has a rope that is 24 yards long. How many pieces of rope measuring 4/7 of a yard can he divide his rope into?
Answers
Answer:
42
Step-by-step explanation:
Chad has a rope that is 24 meters long
He wants to divide the rope so each piece will be 4/7 yards
= 24÷ 4/7
= 24× 7/4
= 168/4
= 42
Hence he can divide the rope into 42 pieces

Loan amount = $9,500
Monthly payments = $227.50
Time of loan contract = 5 years
Interest rate = ____%
Answers
Answer:
Step-by-step explanation:
5x12=60
(227.5x5x120)=13650
13650-9500=4150
apply formula
(2x12x4150)/((13650(60+1))=0.1196
0.1196x100=11.96% 0r 12%
Answer:
17.2%
Step-by-step explanation:
given that:
y = 12 months
m = $9,500
n = 60 (because five years is 60 months)
c = (n * $227.50) - m
= (60 * $227.50) - $9,500
c = 4,150
and now, to substitute the following to the equation:
[tex]\frac{2(12)(4,150)}{9,500(61)} *100[/tex] = 17.2%
whats her errors and whats the soulution
Answers
Answer:
she messed up at -17=34x
Step-by-step explanation:
she added 8x to each side but she was actually supposed to subtract
The error is 8(x - 3) + 7 = 2x(13) and -17 = 34x.
4 - 17 = -13, not 13
8x - 17 = 26x
-17 = 26x -8
-17 = 18x ( it should be like this, but this is still wrong because it should -26)
The solution is:
8(x - 3) + 7 = 2x(4 - 17)
8(x - 3) + 7 = 2x(-13)
8x - 24 + 7 = -26x
8x - 17 = -26x
8x + 26x = 17
34x = 17
x = 17/34
x = 1/2

The spinner below is divided into five equal-sized sectors. What is the probability that the spinner will stop on a number greater than 3?
Answers
Answer:
40%
Step-by-step explanation: If you have five equal-sized sectors, then the probability that the spinner will stop on 4 and 5 is 40%.
The probability that the spinner will stop on a number greater than 3 will be 0.4 or 40%.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.
As per the given,
The spinner below is divided into five equal-sized sectors.
The probability of it stopping more than 3 = probability of stops at 4 + probability of stops at 5.
⇒ 1/5 + 1/5
⇒ 2/5 = 0.4
So, 0.4 x 100 = 40%
Hence "The probability that the spinner will stop on a number greater than 3 will be 0.4 or 40%".

Two rectangular rugs are ordered at Cardi’s furniture: small rugs and large rugs.
Small rugs are 36 inches long and 18 inches wide.

b. Find the ratio of the two perimeters and the ratio of the two areas. Is there anything you notice about these ratios? What can you deduce?
c. It takes 180 feet of yarn to create a square foot of either rug. How many inches of yarn are needed to make the small rug? How many feet or yarn is needed to make the large rug?
d. If a “skein” of yarn costs $4.50 and one skein is exactly 180 feet of yarn, how many skeins of yarn are needed to make the large rug? Given this answer what is the lowest Cardi’s must sell the large rug in order to make a profit
PLEASE HELP EVEN IF U CAN ANSWER JUST 1
Answers
Answer:
a.) yes they are similar shapes, the width for both rugs is 1/2 of the length. This means that they are both similar in shape.
b.) 2:5 (perimeter rug 1 and 2 compared), 4:25 ( area for 1 and 2). The numers in the perimeter ratio are the square root of the numbers in the area ratio.
c.) You will need 648 sq in for the small rug and 4050 sq in for the large rug.
d.) 2: she has to sell the large rugs x>$9 and the small rugs for s>$1.50
Step-by-step explanation:
total perimeter for rug 1 = 108 For rug 2 = 270
area for run 1 = 648 For rug 2 = 4050
180 ft = 2150 in
The large rug needs two skeins of yarn which cost 9 dollars, if she wants to make a profit she will have to sell them over that price.
You can make 3 small rugs with one skein meaning if she wants to make a profit from the small rugs she has to sell them over 1/3 of the price of the skein (which is sold for $4.50). She will have to sell the small rug for over $1.50
