Answers
Answer:
x= [tex]\frac{1}{1028} y[/tex]+[tex]\frac{-339}{514}[/tex]
Step-by-step explanation:
let's solve for x.
y=23x(45)−7x+678
step 1: flip the equation.
1028x+678=y
step 2: add -678 to both sides.
1028x+678+−678=y+−678
1028x=y−678
step 3: divide both sides by 1028.
1028x/1028=y-678/1028
x=1/028 y+-339/514
answer- x= [tex]\frac{1}{1028} y[/tex]+[tex]\frac{-339}{514}[/tex]
good luck :)

10. Tim bought two copies of the same hardcover book and three
copies of the same paperback book cost $118. Sally bought three of
the hardcover books and two of the paperback books for $137. Find
the cost for each type of book.
Answers
Answer:
Let hardcover book be x
Let paperback book be y
2x+3y=$118....Equation 1
3x+2y=$137.... Equation 2
Solve for x and y using simultaneous equation
Using elimination method
2x+3y=118......×3
3x+2y=137......×2
6x+9y=354
6x+4y=274
9y-4y=80
5y=80
y=80÷5=16
substituting y=16 into equation 1
2x+3(16)=118
2x+48=118
2x=70
x=70÷2=35
Therefore hardcover costs $35 each
paperback cover costs $16 each
The combined area of a square and a rectangle is 33 square meters. The width of the rectangle is 1 meter more than the length of one side of the square and the length of the rectangle is 3 meters more
than its width.
a) Calculate the dimensions of the rectangle and its perimeter
b) Calculate the dimensions of the square.
Answers
Answer:
Step-by-step explanation:
Square is x meters on each side.
Area of square = x²
Width of rectangle = x+1
Length of rectangle = x+4
Area of rectangle = (x+1)(x+4) = x²+5x+4
Combined area = 2x²+5x+4 = 33
2x²+5x-29 = 0
x = [-5+√(5²-4(2)(-29))]/[2(2)] = [-5 +√257]/4

In problem 10, how would your work be different if you were asked how many
ounces of tea leaves Taylin could buy with $10?
Answers
Answer:a) $5.64 b) 21 ounces of tea leaves
Step-by-step explanation:
Step 1
5 ounces of tea leaves can be bought with $2.35
1 ounce of tea can be bought with =$2.35/5 =$0.47

Write an equation in point-slope form that describes the line with a slope of -3 that contains the point (1,2)
Answers
Answer:
y - 2 = -3(x - 1)Step-by-step explanation:
The point-slope form of the equation that describes the line with a slope of m that contains the point (x₀, y₀) is: y - y₀ = m(x - x₀)
m = - 3
(1, 2) ⇒ x₀ = 1, y₀ = 2
Therefore:
y - 2 = -3(x - 1)

By selling an article for rs 660 pradeep loses 60 rs at what price he must sell the article to gain 15%
Answers
Answer:
828 rs
Step- -step explanation:
pradeep sold the item for 60 rs less than the cost price
The cost price = amount lost + amount it was sold
60 + 660 = 720 rs
To determine the selling price that would yield a gain of 15%,
calculate 15% of 720. Add the amount derived in the above step to 72015/100 x 720 = 108
108 + 720 = 828 rs

An IQ test is known to have an approximate normal distribution with mean 100 and standard deviation 15. Using the Empirical Rule, about what percentage of test takers will have an IQ score between 85 and 115?
Answers
Answer: 68%
Step-by-step explanation:
Empirical rule is basically using a bell curve along with mean and SD to find the center percentage. So take the mean right. 100 if you add 15 which is the SD you get 115 or 34.1% from 100 to 115. If you do the same thing but subtract this time 100-15=85 34.1% again from 85 to 100. So 85 to 115 is 34.1%+34.1%=68%

No TV 9 3 12
Total 15 15 30
Calculate the relative frequency of the data to determine which association the two-way table suggests.
A.
Students who watch television in the evenings tend to have homework.

Students who watch television in the evenings tend not to have any homework is the association suggested by the two-way table.
Step-by-step explanation:
Of the students who watch television, 33% have homework, and 67% do not have homework.
So, students who watch television in the evening tend not to have homework.
Of the students who do not watch television, 75% have homework, and 25% do not have homework.
So, students who do not watch television in the evenings tend to have homework.

Answers
Answer:
c.
Step-by-step explanation:
Please note that the angle A and B are somewhat close to 45deg, so we expect AC and BC to be close in length.
We can drop answer a on that basis.
We can also drop abswer d on the basis that AC is longer than AB there and that cannot be the case in a right triangle.
We can verify that for both b and c the Pythagoras theorem holds, so we need to choose the answer that fits the angles A and B. Te can check the tan of the angle to get the ratio between BC and AC.
tan(48.8deg) ~= 1.1423
1.6/1.4 ~= 1.1429; close enough.
So we choose answer c.
