Write an equation that represents the line.
Use exact numbers.

The total amount of money collected if Anya and Lauren sold their mangoes at $15 is $10,350

= 575 mangoes

Total number of mangoes = Number of mangoes Anya has + Number of mangoes Lauren has

= 115 + 575

= 690 mangoes

Amount each mangoes was sold = $15

Total amount of money collected = Total number of mangoes × Amount each mangoes was sold

= 690 × 15

= $10,350

So therefore, Anya and Lauren sold their total mangoes for $10,350

[tex] \frac{v}{8} - 4 = - 12 \\ \frac{v}{8} = - 12 + 4 \\ \frac{v}{8} = - 8[/tex]

Now I will use CROSS MULTIPLICATION

[tex]v = 8( - 8) \\ v = -6 4[/tex]

ATTACHED IS THE SOLUTION

Answer: v/8 - 4 = (-12)

-12 + 4 = (-8)

what divided by 8 is 8?

8/8 = 1 so 8 x 8 = 64

this means v = -64

64/8 - 4 = -12

- 64/8 is -8 and that minus 4 is -12

Answer:

D. 9x² - 12x - 1

Explanation:

To find f(g(x)), we need to replace x by g(x) as follows:

f(x) = x² - 5

f(g(x)) = (g(x))² - 5

Then, g(x) is equal to -3x + 2, so replacing g(x) by (-3x + 2), we get:

f(g(x)) = (g(x))² - 5

f(g(x)) = (-3x + 2)² - 5

f(g(x)) = (-3x)² + 2(-3x)(2) + 2² - 5

f(g(x)) = 9x² - 12x + 4 - 5

f(g(x)) = 9x² - 12x - 1

Therefore, the answer is D. 9x² - 12x - 1

The equality of the respective angles and the proportionality of the corresponding sides determine if two triangles are comparable.

Triangle A: 53, 71, Triangle B: 53, 71; Similar

Triangle C: 90, 37, Triangle D: 90, 53; Similar

Triangle E: 63, 45 Triangle F:14, 71; Not similar

Triangle G, 121, Triangles H: 70, Not similar

If two of one triangle's angles are congruent with two of the

angles of a different triangle, then the two triangles are comparable.

Similarity hypothesis, angle, and AA

Given that: The interior product of the AA similarity hypothesis

The angle sum property of a triangle states that the angles of a triangle are 180°,

Consequently, the third angle is also congruent when two angles are

congruent

53, 71 in Triangle A and 53, 71 in Triangle B; similar

Based on the AA similarity postulate, the triangles are similar.

Triangles C (90, 37) and D (90, 53) have similar angles.

Supplied that the given angles are identical to each of their complimentary angles, the triangle is similar.

Triangle F: 14, 71 Triangle E: 63, 45; not comparable

There are no parallel triangles.

Out of 400 students, 120 students would pick math as their favorite subject.

Data provided to us

fav subject       students

 Math                  6

 Science             3

 English              4

 History              7

Hence the total becomes 20 students

we have to calculate students whose favorite subject is math from 400 students

students with math as fav subject out of 20 students = 6

students with math as fav subject out of 400 students = (6 / 20) x 400

                                                                                          = 120 students

we can verify it as

%age of students out of 20 , who like math = 6/20 x 100

                                                                                   = 30 %

similarly, %age of students out of 400, who like math= 120/400 x 100

                                                                                        = 30 %

As we can see both the percentages are same. and the answer is verified .

The original price of the jacket before sale amount is $45.

Original price of the jacket will be calculated by forming the expression relating mentioned price. Let us assume the original price of the jacket to be x.

Writing the equation representing original price, percentage and price after sale

80%×x = 36

Converting percentage to fraction

80/100×x = 36

Shifting the fraction to Right Hand Side of the equation

x = 36×100/80

Cancelling zero as it is common in numerator and denominator and performing division

Dividing a number(integer or fraction) by a fraction is equivalent to multiplying that number by the reciprocal of the divisor fraction

So if you have an expression
[tex]\dfrac{a}{b} \div \dfrac{c}{d}\\\\\implies \dfrac{a}{b} \times \dfrac{d}{c}[/tex]

Question 1

[tex]\dfrac{14x^5}{5y^2}\:\div \dfrac{2x^4}{10y}\\\\= \dfrac{14x^5}{5y^2} \times \dfrac{10y}{2x^4}\\\\[/tex]

[tex]=\dfrac{14x^5\cdot \:10y}{10y^2x^4}[/tex]

10 in the numerator and 10 in the denominator cancel:

[tex]=\dfrac{14x^5y}{y^2x^4}[/tex]

[tex]\dfrac{x^5}{x^4} = x^{5-4} = x \;\;\;\;\;\;\text{Since }\dfrac{x^a}{x^b}=x^{a-b}}[/tex]

Likewise

[tex]\dfrac{y}{y^2} = y^{1-2} = y ^{-1} = \dfrac{1}{y}[/tex]

Therefore
[tex]=\dfrac{14x^5\cdot \:10y}{10y^2x^4} = 14 \dfrac{x}{y} = \dfrac{14x}{y}[/tex]
Answer: Question 1

Question 2

[tex]\left(\dfrac{x}{y}\right)\left(\dfrac{4y}{3x}\right)\:\div \dfrac{6y^2}{8x^2}[/tex]

[tex]\dfrac{x}{y} \cdot \dfrac{4y}{3x} = \dfrac{4}{3}[/tex]

[tex]\dfrac{6y^2}{8x^2} = \dfrac{4y^2}{3x^2}[/tex]'

[tex]\left(\dfrac{x}{y}\right)\left(\dfrac{4y}{3x}\right)\:\div \dfrac{6y^2}{8x^2} \\\\= \dfrac{4}{3} \times \dfrac{3x^2}{4y^2}\\\\= \dfrac{16x^2}{9y^2}[/tex]

The y + 6 terms cancel out from numerator and denominator as do the xy - 3terms

[tex]= \dfrac{5}{2} \times \dfrac{4}{1}\\\\= \dfrac{20}{2} \\\\= 10[/tex]

Question 4

[tex]x^2-4 = (x + 2)(x-2) \;\;\;\; \text{Since $a^2-b^2 = (a +b)(a-b)$}[/tex]

[tex]x^2 + 5x + 4\;\;\; \text{can be factored as: }\\\\(x + 1)(x + 4)[/tex]

Equivalent ratios are the ratios that are the same when we compare them. Three equivalent ratios are 1/2, 4/8, 3/6 in digits from 1 to 9.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other

Equivalent ratios are the ratios that are the same when we compare them.

The digits from 1 to 9 include 1,2,3,4,5,6,7,8,9.

Ratios are nothing but fractions.

Let 1/2 (one by two) is the first ratio.

Now 3/6 (three by six) is the second ratio

4/8 (four by eight) is the third ratio.

If we calculate the value of 1/2 = 0.5

The value of  3/6=1/2=0.5

The value of 4/8= 1/2=0.5

we get the same answer for all the ratios 1/2, 4/8 and 3/6 that is 0.5

That is 0.5 or 1/2.

Hence the three equivalent ratios are 1/2, 4/8, 3/6.
