8. Negative three times the sum of a number and two is fifteen
Answers
Answer:
-3(n + 2)= 15
Step-by-step explanation:
Based on this question, we know that the equation involves multiplication. Here we start our equation with -3!
Then it says "times the sum of a number and two" So let's just say the "number" is "n". The word "sum" means the answer to an addition problem, thus we know that we are adding "n" and 2. Let's put that in parenthesis!
-3(n+2)
And it says "is fifteen" which also means "equals to fifteen"
Therefore, the answer is:
-3(n + 2) = 15

Hi there!
∠SRQ = 162°
∠STR = 130°
∠RST = ?
Now;
∠SRQ = ∠RST+∠STR [external angle is equal to the sum of opposite interior angles of triangle]
∠RST = ∠SRQ-∠STR
∠RST = 162°-130°
Therefore, the measure of ∠RST is 32°.

It took a car 2 days to travel 2274 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)
Answers
Answer:
47 mph
Step-by-step explanation:
1 day = 24 hours, so 2 days = 48 hours.
2274/48 (2274 miles per 48 hours, simplify!) This equals 47.375. Round it down to 47 mph.
This is assuming the car took no breaks.

Hooke’s Law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 180 newtons stretches a spring 5 cm, how much will a force of 270 newtons stretch the same spring?
Answers
Answer:
Simple springs obey Hooke's Law. Hooke's Law states that the force on a spring is proportional to it's displacement from it's resting length:
F = -k*x
Where F is the force, x is how far the string is stretched or compressed, and k is a proportionality constant called the spring constant. The negative sign is because the spring resists stretching.
In this case, we can solve for k using the first case:
(100N) = -k * (5cm)
k = ???
And plug that answer in to find x in the second case:
(360N) = -k * x
This is a "Hooke's Law" problem: the restoring force required to compress or stretch a spring is proportional to the distance the spring is deformed. You can figure solve it by setting up a proportion equation and then using the algebraic tool of cross multiplication to solve for the unkown "stretch".
1) set up the proportion equation
100 = 360
5 x
2) cross multiply to get a linear equation
100x = 5*360
3) solve for x
100x = 1800
x = 18

Answer:
The law: F=kx
Therefore,
180N = k * 5cm
k = 180÷5= 36N per cm
Using the known constant with the law,
270=36*x
x= 270 ÷ 36 = 7.5cm

also please solve and "product" means multiply.
Answers
-2 * 5 + d = 14
Solving by multiplying -2 and 5 first:
-10 + d = 14
Add 10 to both sides to get rid of the negative 10:
-10 + d + 10 = 14 + 10
-10 plus 10 gives 0 and it cancels out so:
d = 24 is the solution.
