The number of tree shades and evergreens will be 42 and 36, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
An engineer purchased 78 trees at an all-out cost of $4050. The overhanging trees cost $45 each and the evergreens cost $60 each.
Let 'x' be the number of tree shades and 'y' be the number of evergreens. Then the equations are given as,
x + y = 78 ...1
45x + 60y = 4050 ...2
From equations 1 and 2, then we have
45(78 - y) + 60y = 4050
15y = 540
y = 36
Then the number of tree shades will be given as,
x + 36 = 78
x = 78 - 36
x = 42
The number of tree shades and evergreens will be 42 and 36, respectively.
More about the solution of the equation link is given below.

Bob drove at an average speed of 15km/h correct to the nearest unit. He drove for 3 hours, correct to the nearest hour. What is the lower bound for the distance he drove?
Answer:
45km
Step-by-step explanation:
Given data
Average Speed= 15km/h
Time = 3 hours
Required
The distance traveled
Speed= distance/time
Distance= speed*time
Distance= 15*3
Distance= 45km
Hence the lower bound of the distance is 45km

2. } (x – 10) = -4
Step-by-step explanation:
For no 1
25 - 3x = 40
- 3x = 40 - 25
- 3x = 15
- x = 15 / 3
Therefore x = - 5
Now for no. 2
1/3 ( x - 10) = - 4
( x - 10 ) = - 12
x = - 12 + 10
Therefore x = - 2

hich scenario best describes an object with a displacement of zero?
A train moves uphill as it travels in a straight path.
A person walks 2 miles north and 2 miles west.
A ball rolls from the top to the bottom of a hill.
A race car starts and ends at the same point on a track.
Answer: C. A Ball Rolls from top to the bottom of a Hill
Step-by-step explanation: In order for this to be a displacement of 0, we need a vector quantity, so we need to specify a magnitude and direction in order to fully characterize it. Unlike distance, which can only get larger on any path taken, displacement can be positive, negative, or zero. Displacement is zero when you start and end at the same spot.
En un triángulo rectángulo A es un ángulo agudo y Sen A = 4/5 ¿Cuál será el valor de Tan A?
Answer:
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]
Step-by-step explanation:
Funciones Trigonométricas
La identidad principal en trigonometría es:
[tex]sen^2A+cos^2A=1[/tex]
Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.
Dado que Sen A = 4/5, calculamos el coseno:
[tex]cos^2A=1-sen^2A[/tex]
Sustituyendo:
[tex]\displaystyle cos^2A=1-\left(\frac{4}{5}\right)^2[/tex]
[tex]\displaystyle cos^2A=1-\frac{16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{25-16}{25}[/tex]
[tex]\displaystyle cos^2A=\frac{9}{25}[/tex]
Tomando raíz cuadrada:
[tex]\displaystyle cos\ A=\sqrt{\frac{9}{25}}=\frac{3}{5}[/tex]
La tangente se define como:
[tex]\displaystyle \tan A=\frac{sen\ A}{cos\ A}[/tex]
Substituyendo:
[tex]\displaystyle \tan A=\frac{\frac{4}{5}}{\frac{3}{5}}[/tex]
[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

-10x + 5y = 10
x - 5y = -28
−10x+5y=10
x−5y=−28
Rewrite equations:
x−5y=−28
−10x+5y=10
Step: Solve:
x−5y=−28
x−5y+5y=−28+5y(Add 5y to both sides)
x=5y−28
Step: Substitute:
−10x+5y=10
−10(5y−28)+5y=10
−45y+280=10(Simplify both sides of the equation)
−45y+280+−280=10+−280(Add -280 to both sides)
−45y=−270
−45y
−45
=
−270
−45
(Divide both sides by -45)
y=6
Step: Substitute:
x=5y−28
x=(5)(6)−28
x=2(Simplify both sides of the equation)
Answer:
x=2 and y=6
