Answer:
A: -4
Step-by-step explanation:
Expand first, "-5 x 3n = -15n" , "-5 x 4 = -20"
Then you have "-15n - 20 = 40"
Transfer the -20 to the RHS,
Then you have "-15n = 60"
Divide both sides by -15
n = -4

Rewrite the sum of 75+18 as a product of a number and another sum
Answer:
(2)(9) + 75 = 75+18
Step-by-step explanation:
(2)(9) + 75 = 75+18
The expression written as a product of a number and another sum is 3(25 + 8)
Given the expression 75 + 18, we are to write as a product of a number and another sum.
First we need to find the GCF of 75 and 18
75 = 3 * 25
18 = 3 * 6
Since 3 is common to both D+GCF, we can factor it out from the expression to have:
75 + 18 = 3(25 + 8)
Hence the expression written as a product of a number and another sum is 3(25 + 8)

x=0.60*9=5.4 choice B
The measure of x side.
We have given a right angle triangle whose angle A=31 degrees and two sides that is x and 9.
We have to determine the value of x.
Therefore we use here the trigonometric ratio
What is the tan ratio?[tex]tan\theta=\frac{opposite side}{adjacent side}[/tex]
Therefore we get
tan 31= x/9
tan(31)=0.60
0.60=x/9
Isolate the x
x=0.60*9
x=5.4
Therefore option B is correct.

8(x – 3) – (6 – 2x) = 2(x + 2) – 5(5 – 2)
Answer:
x= [tex]\frac{19}{8}[/tex]
Step-by-step explanation:
8(x−3)−(6−2x)=2(x+2)−5(5−2)
Step 1: Simplify both sides of the equation.
8(x−3)−(6−2x)=2(x+2)−5(5−2)
8(x−3)+−1(6−2x)=2(x+2)−5(5−2)(Distribute the Negative Sign)
8(x−3)+(−1)(6)+−1(−2x)=2(x+2)−5(5−2)
8(x−3)+−6+2x=2(x+2)−5(5−2)
(8)(x)+(8)(−3)+−6+2x=(2)(x)+(2)(2)+−5(5−2)(Distribute)
8x+−24+−6+2x=2x+4+−15
(8x+2x)+(−24+−6)=(2x)+(4+−15)(Combine Like Terms)
10x+−30=2x+−11
10x−30=2x−11
Step 2: Subtract 2x from both sides.
10x−30−2x=2x−11−2x
8x−30=−11
Step 3: Add 30 to both sides.
8x−30+30=−11+30
8x=19
Step 4: Divide both sides by 8.
8x/8=19/8
Answer: x=[tex]\frac{19}{8}[/tex]
8(x - 3) - (6 - 2x) = 2(x + 2) - 5(5 - 2)
8*x - 8*3 - 6 + 2x = 2*x + 2*2 - 5*3
8x - 24 - 6 + 2x = 2x + 4 - 15 ( Cancel equal terms on both sides of the equation)
8x - 24 - 6 = 4 - 15
8x - 30 = -11
8x = -11 + 30
8x = 19
x = 19/8

A truck is 180 inches long. A car is 30% shorter than the truck. How long is the car?
On a map with a scale of 0.25 inch = 30 miles the distance between two cities is 8.3 inches
Answer:
Step-by-step explanation:
8.3÷0.25
Multiply that by 30 and you get 996
The actual distance between the two cities will be 996 miles.
What is the distance?Distance is defined as the product of speed and time.
Scale is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
The given scale is 0.25 inches on the map representing 30 miles.
If the distance between two cities is 8.3 inches
As per the given scale, the actual distance between the two cities will be as:
⇒ 8.3 × 30/0.25
⇒ 83/10 × 3000/25
⇒ 249,000/250
Apply the division operation, and we get
⇒ 996 miles

In ΔHIJ, h = 450 cm, i = 210 cm and j=640 cm. Find the measure of ∠I to the nearest degree.
Answer:
10
Step-by-step explanation:
The measure of an angle∠I is 10 degrees between the 450 cm and 640 cm sides.
What is the Cosine Rule?The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
c² = a² + b² − 2ab cos(C)
The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.
In the given triangle ΔHIJ,
Sides:
h = 450 m
i = 210 m
j = 640 m
The angle of ∠I is 10 degrees between the 450 cm and 640 cm sides.
According to the cosine rule,
j² = h² + i² − 2ab cos(I)
Substitute the values in the Cosine Rule,
450² = 210² + 640² - 2(210)(640)cos(I)
After solving we get the value of angle ∠I :
∠I = 9.56038°
Rounded to the nearest degree.
∠I = 10°
Thus, the measure of an angle∠I is 10 degrees.

A boat goes 24 miles at a constant speed in 4 hours against a river current.
It takes the boat 3 hours to go the same distance at the same speed with the
current of the river. What is the speed of the boat and what is the current of
the river?
The speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
A boat goes 24 miles at a constant speed in 4 hours against a river current.
It takes the boat 3 hours to go the same distance at the same speed with the current of the river.
Let's suppose the speed of the boat is x miles/hour and the current of the river is y
x- y = 24/4
x - y = 6 ..(1)
x + y = 24/3
x + y = 8 ..(2)
Adding equation (1) and (2):
2x = 14
x = 7 miles/hour
y = 8 - 7 = 1 miles/hour
Thus, the speed of the boat is 7 miles/hour and the current of the river is 1 mile/hour.
