Answer:

$1\dfrac{17}{19}$

Step-by-step explanation:

19 bananas =1 watermelon

3 pineapples =1 watermelon

Then

19 bananas = 3 pineapples

1 pineapple = 3 grapes,

then

3 pineapples = 9 grapes

3 pineapples = 9 grapes

19 bananas = 3 pineapples

then

9 grapes = 19 bananas

9 grapes = 19 bananas

x grapes = 4 bananas

Write a proportion:

$\dfrac{9}{x}=\dfrac{19}{4}$

Cross multiply

$19x=9\cdot 4\\ \\19x=36\\ \\x=\dfrac{36}{19}=1\dfrac{17}{19}$

Express the ratio in the simplest form. 20 gallons to 0.75 gallons

expeople1 [14]

ANSWER

The ratio in the simplified form is

80:3

EXPLANATION

We want to express 20 gallons to 0.75 gallons as a ratio in its simplest form.

We obtain the ratio as follows:

$20:0.75$

This is the same as

$20: \frac{3}{4}$

We multiply each term in the ratio by 4 to obtain;

$20 \times 4:0.75 \times 4$

This gives us,

$80:3$

Question 22.). Write the equation in Standard Form:

10y = 12x + 0.7

Identify: A, B, C

Standard Form for Linear Equation: Ax + By = C

10y = 12x + 0.7

The Standard Form of the solution is

Ax + By = C, Where, A ≥ 0

A and B, are Non- Zero numbers.

Therefore, Your answer, Letter Choice, (D), 120x - 100y = - 7, Where,

A = 120, B = - 100, and C = - 7

Question 24.). Described as, Inconsistent, Consistent, and Independent, Consistent, and Dependent, or None of These.

9x - 8y = 15, and 27x - 24y = 3

Solve:

9x - 8y = 15; 27x - 24y = 3

Steps: I will try to solve the system of equation:

9x - 8y = 15; 27x - 24y = 3

Step, Solve: 9x - 8y = 15 for x

9x - 8y + 8y = 15 + 8y

Add 8y to both sides:

9x = 8y + 15

9x/9 = 8y + 15/9 ( Divide both sides by 9):

x = 8/9y + 5/3

Step Substitute:

8/9y + 5/3 for X in 27x - 24y = 3

27x - 24y = 3

27 ( 8/9y + 5/3) - 24y = 3

45 = 3

Simplify Both sides of equation:

45 + - 45 = 3 + - 45 ( Add - 45, to both sides.):

0 = - 42

Therefore, No real Solutions, to both Equation.

Hence; 9x - 8y = 15; and 27x - 24 = 3, have No Real Solutions, and Therefore, They are, Answer Letter Choice, (B), Inconsistent.

Hope that helps!!! Sorry, I couldn't figure out Number (23.). : )

How 2 do? (n)(n+7)(n+8)

madreJ [45]

Answer:

$n^{3} + 15n^{2} + 56n$

Step-by-step explanation:

First FOIL (n + 7)(n + 8) and then distribute n

(n + 7)(n + 8) = $n^{2} +15n + 56$

n ( $n^{2} +15n + 56$ )

= $n^{3} + 15n^{2} + 56n$
