Answer:
x = 31
Step-by-step explanation:
I will make the explanation easy for you to understand.
Step 1: Subtract 12x from both sides.
13x − 15 − 12x = 12x + 16 − 12x
x − 15 = 16
Step 2: Add 15 to both sides.
x − 15 + 15 = 16 + 15
x = 31

peter, henry and john shared $345 between them. Peter received $45, henry received $75 and john received the rest.
a) find the ratio of peters share to henrys share to johns share
Answer:
Step-by-step explanation:
Let J = John's share ($)
P = Peter's share ($)
H = Henry's share ($)
1) H = P + 80
2) J/P = 6/3 = 2
3) P/H = 3/5
Substitute equation 1) into equation 3)
P/(P + 80) = 3/5 (multiply both sides by (P + 80)
P = (3/5)*(P + 80) (multiply both sides by 5)
5*P = 3*P + 240
2*P = 240
P = 240/2 = $120
Substitute P value into equation 2)
J/P = 2 or
J = 2*P = 2*$120 = $240
John received $240
A walli can be built by 6 men working for 8 hours per day in 5 days. How many days will it take 4 men to build if they work only 5 hours per day.
(show your working)
Answer:
A wall can be built by 6 men working 8*5*6=240 hours.
If 4 men works 5 hours a day, they work 20 hours/day.
It will take them 240 hours /20 hours = 12 days
During a day a student spends 7 hours sleeping, ¹/4 of the day studying and of the time travelling. What fraction of the day is left for other things?
Answer:
45.83 over 1 (45.83/1)

Solve the equation shown:
-5(x - 3) +7x = 35
x =
Answer:
10
Step-by-step explanation:
[tex]-5(x-3)+7x=35[/tex]
Distribute the 5
[tex]-5x+15+7x=35[/tex]
Combine like terms
[tex]2x+15=35[/tex]
Subtract 15 to isolate the variable
[tex]2x=20[/tex]
Divide by 2
[tex]x=10[/tex]
Answer:
x = 10
Step-by-step explanation:
Simplify by applying the distributed property: -5x - -15 + 7x = 35Simplify: -5x + 15 + 7x = 35Combine like terms: 2x + 15 = 35Subtract 15 from each side, so it now looks like this: 2x = 20Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = 10I hope this helps!

Answer:
:) /
Step-by-step explanation:,,
Answer:
The answer is B:subtract 1,add x,divide by 4
The other answer is D:add x,subtract 1,divide 4
Step-by-step explanation:
when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3
the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=[tex]\frac{3}{4}[/tex]
The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=[tex]\frac{3}{4}[/tex]
With that evidence I can reasonably say that answer to the question is B,and D

Choose the true statement about the graph of x > -3.
closed circle on -3 and all numbers to the right shaded
open circle on -3 and all numbers to the right shaded
open circle on -3 and all numbers to the left shaded
Answer:
The second one
Step-by-step explanation:
The true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.
What is Number system?A number system is defined as a system of writing to express numbers.
A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.
The given inequality is x>-3.
The value of x should be greater than -3.
The value -3 is not included.
In a number line the values are increased from left to right.
As x is greater than -3 which means the x values are increasing from left to right.
So the statement open circle on -3 and all numbers to the right shaded is true statement.
Hence, the true statement about the graph of x > -3 is open circle on -3 and all numbers to the right shaded.

Answer:
Step-by-step explanation:
Hey :)
Keep in mind:
y = mx + b
Where m = slope and b = y-intercept
Since we are told:
y = 9x - 3
This means m = 9 and b = -3
Therefore the slope is 9 and y-intercept is at (0,-3)

Step-by-step explanation:
Suppose you want to accumulate $25,000 as down payment on a house and the best you can do is to put aside $200 a month. If you deposit this amount at the beginning of each month in an account that credits 0.75% interest monthly, how long will it take you to attain your goal?
Answer:
It will take 88.2 months to accumulate the amount
Step-by-step explanation:
Given;
Future value of money, FV = $25,000
investment per compound period, P = $200
interest rate, i = 0.75% x 12 = 9%
The number of monthly installments required to amount to FV is given by;
[tex]n = \frac{ln(FVi +cp)-ln(cp)}{ln(c+i)-ln(c)}\\\\ n = \frac{ln(25000*0.09 +200*12)-ln(200*12)}{ln(12+0.09)-ln(12)}\\\\n = \frac{8.4446 -7.7832}{2.4924-2.4849}\\\\n = 88.2 \ months[/tex]
Therefore, it will take 88.2 months to accumulate the amount.
