Answer:
x = 2.5
Step-by-step explanation:
- 2x - ( - 5 - 4x ) = - 5 ( 2x - 7 )
- 2x + 5 + 4x = - 10x + 35
- 2x + 5 + 4x = - 10x + 35
- 2x + 4x + 10x = 35 - 5
12x = 30
x = [tex]\frac{5}{2}[/tex] = 2.5
Check the answer:
L.H.S. = - 2(2.5) - [ - 5 - 4(2.5) ] = 10
R.H.S. = - 5 [ 2(2.5) - 7 ] = 10
Solve for: 22≥4m-2 or 5-3m≤-13
Answer:
22≥4m-2=6
5-3m<-13=6
Step-by-step explanation:
The inequalities 22 ≥ 4m - 2 or 5 - 3m ≤ - 13 is m ≤ 6 or m ≥ 6.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
22 ≥ 4m - 2.
4m ≤ 22 + 2.
4m ≤ 24.
m ≤ 24/4.
m ≤ 6.
5 - 3m ≤ - 13.
- 3m ≤ - 13 - 5.
- 3m ≤ - 18.
3m ≥ 18.
m ≥ 18/3.
m ≥ 6.
So, m ≤ 6 or m ≥ 6.

2. An item used to sell for seventy-five cents a pound, and you see that it's been marked up to
eighty-one cents a pound. What is the percent increase?
Answer:
4%
Step-by-step explanation:
Answer:
It is not 4%. The answer is 8%
Step-by-step explanation:
First subtract .75 from .81 and you get the difference between the two prices .06 cents. Now use the formula % = (amount of increase)/(original amount) * 100.
Substitute and you get X = .06/.75 * 100
X = 6/.75 (.06 * 100 = 6)
X = 8

what is the estimate the product of 324 × 26 pls help me I forgot how to estimate
Answer:
(Not only one answer)
Step-by-step explanation:
Estimate means to round in a way.
I would do this by making the equation to ...
320 x 20
or
320 x 25
or
320 x 30
or
325 x 25
etc.
its 9600 because the rounded up of 324 is 320 and the rounded up of 26 is 30 so 320×30 is 9600
Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a
trainer. For how many sessions is the cost of the two plans the same?
Answer: For 10 sessions, the cost of the two plans the same.
Step-by-step explanation:
Let x= Number of sessions.
Given: Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Total charge for x sessions = 50+30x
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a trainer.
Total charge for x sessions = 250+10x
When both plan charges the same, then
[tex]50+30x=250+10x\\\\\Rightarrow\ 30x-10x=250-50\\\\\Rightarrow\ 20x=200\\\\\Rightarrow\ x=10[/tex]
i.e. For 10 sessions, the cost of the two plans the same.

If $5000 is put into a savings account that pays
3.5% interest compounded monthly, how much
money, to the nearest ten cents, would be in that
account after 6 years, assuming no money was
added or withdrawn?
Answer:
17600
Step-by-step explanation:
calculator
Based on the amount of money being saved and the amount of time it will be saved, the amount in the account after 6 years would be $6,166.51
The interest is compounded monthly which means that you need to convert the interest to a monthly figure as well as the number of years you will be investing:
3.5% / 12 months = 3.5/12%
6 years x 12 = 72 months
The amount after 6 years is:
= Amount x (1 + rate) ^ number of periods
= 5,000 x (1 + 3.5/12%)⁷²
= $6,166.51
In conclusion, the amount in the account after 6 years is $6,166.51.

If a bike is going at 26 centimeters per second how many meters per minute is she traveling?
Answer:
15.6 meters in a minute
Step-by-step explanation:
Here's why:
1 centimeter= 0.01 meter
So, if you have 26 cm, that equals 0.26 meters.
Now, we know that there are 60 seconds in a minute.
So, we have to do 0.26 times 60 which equals 15.6 meters.

A trucks position relative to a cars position is -60 feet. The car and the truck move in the same direction , but the car moves 5 feet per second faster for 8 seconds. What operations could be used to find the trucks relative position after 8 seconds. EXplain
Answer:
The truck's relative position with respect to the car is: -100 feet
Step-by-step explanation:
If the truck is moving at a seed "V" then its position after 8 seconds is going to be:
XT = V* t = V * 8 = 8 V
The car, which is initially 60 feet ahead of the truck and starts moving at 5 m/s faster than the truck, would have a speed given by: V + 5
And its position (relative to the truck's) would be:
XC = 60 + (V + 5) * t = 60 + (V + 5) * 8 = 60 + 40 + 8 V = 100ft + 8 V
then the position of the truck relative to that of the car would be given by the difference:
XT - XC = 8 V - (100 +8 V) = 8 V - 8 V - 100ft = -100 feet
