Answer:
x=7
Step-by-step explanation:
8(2x-10)+18=4x+22
distribute the 8
16x-80+18=4x+22
simplify
16x-62=4x+22
ads 62 to each side
16x=4x+84
subtract 4x from each side
12x=84
divide each side by 12
x=7

Sarah has a brother who is 5 years younger than herself and another brother who is 8 years younger than herself. She observes that the product of her brothers ages is equal to the age of her 40 year old father. How old is Sarah? How do we setup an equation for this using null factor law presumably.
Answer:
Sarah is 13 years old
Step-by-step explanation:
Represent Sarah's age with S
Her first brother's age with F
Her second brother's age with B
So, we have:
From the first statement, we have:
[tex]S - F = 5[/tex] ---- (1)
From the second, we have:
[tex]S - B = 8[/tex] ---- (2)
The product of their ages is 40.
First, we make F the subject in (1) and B the subject in (2)
[tex]F = S - 5[/tex]
[tex]B = S - 8[/tex]
Their product is represented as follows:
[tex]F * B = 40[/tex]
Substitute values for F and B
[tex](S - 5) * (S - 8)=40[/tex]
Open bracket
[tex]S^2 - 5S -8S + 40 = 40[/tex]
[tex]S^2 - 13S + 40 = 40[/tex]
Subtract 40 from both sides
[tex]S^2 - 13S = 0[/tex]
Factorize:
[tex]S(S - 13) = 0[/tex]
Split:
[tex]S = 0[/tex] or [tex]S - 13 = 0[/tex]
But Sarah's age can't be 0 because she has two younger brothers.
So, we stick to
[tex]S - 13 = 0[/tex]
Make S the subject
[tex]S = 13[/tex]
Hence, Sarah is 13 years old

suppose you deposit $2500 in a savings account that pays you %5 interest per year. how many years will it take for you to double your money? how many years will it take for your account to reach $8000?
Answer:
t = 44 years
Step-by-step explanation:
t = (1/r)(I/P-1)
t = (1/0.05) {(8000/2500) - 1}
t = 44

We should picture a right angled triangle with hypotenuse 50 and one of the other sides as 35
To find the height in this case, we proceed to use Pythagoras’ theorem which states that the square of the hypotenuse equals the sum of the squares of the two other sides
In this case, let the height be
50^2 = 35^2 + h^2
h^2 = 50^2-35^2
h^2 = (50+35)(50-35)
h^2 = (85)(15)
h^2 = 1275
h = square root of 1275
h = 35.71 ft

A builder is building a fence with 6-inch-wide wooden boards, arranged side-by-side with no gaps. How many boards are needed to build a fence that is 150 inches long?
Answer:
25 wooden boards
Step-by-step explanation:
Given that:
Width of wooden board = 6 inches
Number of boards required to build a fence of 150 inches long if there are no gaps :
The lenght of fence / width of wooden board
= 150 inches / 6 inches
= 25 wooden boards

It takes Frank 2 hours to build a fence. It takes Tom 9 hours to build the same fence. How long would it take to build the fence if Frank and Tom built the fence together?
Answer:
5 1/2 hours
Step-by-step explanation:
You would have to add 2 and 9 and then divide by 2. (Find the average of the two)
2 + 9 = 11
11 / 2 = 5.5
So if you add their times then divide you receive and average of five and a half hours.
Noah's oven thermometer gives a reading that is 2% greater than the actual temperature if the actual temperature is 350°F what was the motor reading be
Answer:
357°FStep-by-step explanation:
Step one:
given data
actual reading= 350°F
thermometer reading 2% of the actual reading
Step two:
Required:
The thermometer reading
let us find 2% of 350°F
2/100*350°
=0.02*350
=7°F
Hence the thermometer reading is 7°F greater than 350°F
The thermometer reading is 350+7=357°F

The smiths went to Larosa's for dinner and spent $42.50 on dinner. There is a 6.5% tax and they want to give a tip of 20% before the tax is added. What is the total price of their bill?
Answer:
Step-by-step explanation:
cost of dinner = $42.5
Tax = 6.5%
Tip = 20%
Total amount percent on food = 26.5%
Amount paid on the original price = 26.5% of $42.5
Amount paid on the original price = 0.265*42.5 = $26.5625
Total price of the bill = $42.5 + $26.5625
Total price of bill = $69.0625
