Fragrant Fields Greenhouse sells rose bushes for $19.90 each. Last weekend, they made $477.60 on rose bushes. How many rose bushes did they sell?
Answer:
Fragrant Fields Greenhouse sold 24 rose bushes.
Step-by-step explanation:
We know that:
1 rose bush = $19.90
And last weekend, the company ended up making $477.60 on rose bushes.
An equation that can represent this situation is:
19.90x = 477.60
To find x, divide:
477.60 ÷ 19.90 = 24
CHECK IT:
19.90(24) = 477.6
That is also $477.60, in terms of money
THEREFORE, the company sold 24 rose bushes.
Hope this helps!
Find the missing value
Answer:
? = 24/23 or 1 1/23
Step-by-step explanation:
In order to do this you have to:
1) Isolate the variable
- you do this by dividing each side by factors that don't contain the variable
- you divide because it is the opposite of multiplication

Answer:
x ≈ 13.5
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan34° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{20}[/tex] ( multiply both sides by 20 )
20 × tan34° = x , then
x ≈ 13.5 ( to the nearest tenth )

Un microempresario realiza una inversión donde le pagan una rentabilidad del 5,36% mensual simple, él desea que esa inversión se triplique ¿Cuánto tiempo deberá esperar para que esto ocurra?
Answer:
Deberá esperar 37.31 años para que esto ocurra.
Step-by-step explanation:
Este es un problema de interés simple.
La fórmula del interés simple viene dada por:
[tex]E = P*I*t[/tex]
En el que E es la cantidad de interés ganado, P es el principal (la cantidad inicial de dinero), I es la tasa de interés (anual, como decimal) y t es el tiempo.
Después de t años, la cantidad total de dinero es:
[tex]T = E + P[/tex]
5,36% mensual simple
Esto implica que [tex]I = 0.0536[/tex]
Inversión se triplique ¿Cuánto tiempo deberá esperar para que esto ocurra?
Tiempo t para que la cantidad de interés sea lo doble de la cantidad inicial, o sea, [tex]E = 2P[/tex].
[tex]E = P*I*t[/tex]
[tex]2P = P*I*t[/tex]
[tex]It = 2[/tex]
[tex]0.0536t = 2[/tex]
[tex]t = \frac{2}{0.0536}[/tex]
[tex]t = 37.31[/tex]
Deberá esperar 37.31 años para que esto ocurra.

Answer:y=x-5
Step-by-step explanation: Use (y2-y1)/(x2-x1) fill those in and get (4-1)/(9-6) which is 3/3 and that is 1 for the slope. Now fill in y=1x with a given coordinate and try to find the y-intercept so we would do 1=1(6) and we need to make the right side equal to the left so we subtract 5. Ending us with y=x-5.

A line passes through (-3, -1) and is parallel to the graph of y= 2x +3. What equation represents the
line in slope-intercept form?
PLEASE HELPPP
Answer:
y = 2x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x + 3 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, so
y = 2x + c ← is the partial equation
To find c substitute (- 3, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = 2x + 5 ← equation of parallel line
The Equation of line is y = 2x + 5.
What is slope of a line?The ratio of a line's change in y coordinate to its change in x coordinate is known as its slope.
Both the net change in the x-coordinate is Δx and the net change in the y-coordinate are represented by Δy.
Given Equation
y = 2x + 3
and line passes through (-3, -1)
equation of line is given by,
y =mx + c
where m is slope, given equation is parallel to graph the value of slope is equal for both
m = 2 from given equation
new equation is y = 2x + c
substitute values of x and y
-1 = 2(-3) + c
c = -1 + 6
c = 5
Equation of line is y = 2x + 5
Therefore the equation represents,
the line in slope-intercept form is y = 2x + 5
