What is the Solution of
7x + 9 = 5x - 3 ?
Answer:
x = -6
Step-by-step explanation:
Original Equation:
7x + 9 = 5x - 3
Subtract 9 from both sides
7x = 5x - 12
Subtract 5x from both sides
2x = -12
Divide both sides by 2
x = -6

[tex]3x+7=22\\\\3x=15\\\\x=5[/tex]
you can leave it here
[tex]3x+7=22[/tex]
if you need the value of x
then

12. According to a survey conducted by the American Pet Products Association, 68% of U.S. households own a pet. According to the Energy Information Administration, 31% of all U.S. households have trouble paying their energy bills. Suppose 17% of all U.S. households own a pet and have trouble paying their energy bills. If a U.S. household is randomly sampled, a. What is the probability that the household owns a pet or is having trouble paying energy bills
Answer:
0.82
Step-by-step explanation:
We are given;
P(households own a pet) = 68% = 0.68
P(have trouble paying their energy bills) = 31% = 0.31
P(households own a pet & have trouble paying energy bills) = 17% = 0.17
Now, to find the probability that a household either owns a pet or having trouble paying energy bills is gotten by the relationship;
P(households own a pet or have trouble paying energy bills) = P(households own a pet) + P(have trouble paying their energy bills) - P(households own a pet & have trouble paying energy bills)
This gives;
P(households own a pet or have trouble paying energy bills) = 0.68 + 0.31 - 0.17 = 0.82

The length of a rectangle is 4 feet less than twice its width, while the perimeter is 15.
Answer:
width: 3.83
length: 3.66
Step-by-step explanation:
The perimeter of a triangle is calculating by adding all the sides together (length + length + width + width). Since we are given the formula for the length we can simply substitute that formula and solve for the width which would be the only variable in the equation.
length + length + width + width = 15
(2w-4) + (2w-4) + w + w = 15 ... combine like terms
6w - 8 = 15 ... add 8 on both sides
6w = 15 ... divide both sides by 6
w = 3.83
Now that we know the value for the width we can plug it into the formula for the length to find its value
l = 2w - 4
l = 7.66 - 4
l = 3.66
Finally, we can see that the rectangle has a width of 3.83 and a length of 3.66
If a fuel efficient car can go 210 miles
on 4 gallons of fuel, how far can it go
on 12 gallons?
Answer:
The distance covered by the car in 12 gallons of fuel is 630 miles.
Step-by-step explanation:
Distance covered by car in 4 gallons of fuel = 210 miles.
Let us use unitary method to find distance covered by car in 1 gallon of fuel.
Distance covered by car in 1 gallon of fuel = 210/4 miles.
Let us use unitary method to find distance covered by car in 12 gallon of fuel.
Distance covered by car in 12 gallons of fuel = (210/4)*12 = 630 miles.

12.1.33 Question Help Suppose that 62% of families living in a certain country own an HDTV and 16% own a computer. The Addition Rule might suggest, then, that 78% of families own either an HDTV or a computer. What's wrong with that reasoning?
Answer:
Step-by-step explanation:
Suppose :
62% own an HDTV
16% own a computer
Using the addition rule : suggests that (62% + 16%) = 78% either own an HDTV or a computer.
The reasoning is wrong because ; since it is possible to own both an HDTV and also own a computer at the same time, the outcome of the addition rule is wrong as both events are independent. If both event cannot occur at the same time (mutually exclusive event) , then, the addition rule may be applied,. But since both can occur independently and each family can own an HDTV while also owning a computer, then the addition rule is wrong for the scenario described.

The units of the subway map below are in miles. Suppose the routes between stations are straight. Station G, not shown on the map, is 5 miles east and 7 miles south of Station A. What is the approximate distance between Station E and Station G when traveling by subway?
Answer:
8.60 miles
Step-by-step explanation:
If S=station G, not shown on the map, is 5 miles east and 7 miles south of Station A, the approximate distance between Station E and Station G when traveling by subway will be gotten using the Pythagoras theorem.
EG² = 5²+7²
EG² = 25+49
EG² = 74
EG = √74
EG = 8.60 miles
Hence the approximate distance between Station E and Station G when traveling by subway is 8.60miles

Answer:
From Post Office to Store is 7.8 miles Henry would walk 2.2 hStep-by-step explanation:
From Post Office (P) to Library (L) is 6 miles, from Store (S) to Library (L) is 5 miles. And angle SLP is right angle (m∠SLP=90°).
So, from Pythagorean theorem:
[tex]SL^2+PL^2=SP^2\\\\5^2+6^2=SP^2\\\\SP^2=25+36=61\\\\SP=\sqrt{61}=7.810 249...\approx7.8[/tex]
If Henry walks 3.6 mph then:
[tex]3.5\qquad-\quad\quad1\,h \\7.8\qquad-\qquad x\\\\ x=\dfrac{7.8\cdot1\,h}{3.5}=\dfrac{78\,h}{35}=2,22857...\, h\approx2.2\,h[/tex]
