2|4x-5|-2=-4 how do I solve this?
Step-by-step explanation:
in my opinion
2(4x-5)-2=-4
=2×4x-2×5-2=-4
8x-10-2=-4
8x=-4+10+2
8x=-4+12
8x=-16(divide both sides by 8)
×=2

I promise this the last one but how do you do these type of problems?
Answer:
0.96 + 0.43v
Step-by-step explanation:
You simplify, v and -0.57v are like terms, therefore you can add them together
v - 0.57v = 0.43 v
Answer:
0.96 + 0.43v
Step-by-step explanation:
What you are doing is combining like terms. Let's say v is candy I have v - .57v that means I have one candy and I ate .57 of it already so we subtract to get .43v and the .96 is brussel sprouts. We do NOT want to mix the candy and the brussel sprouts because they are different things.
If you need me to explain more let me know, but hopefully this helps and have a great day!

Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?
Answer:
96 miles
Step-by-step explanation:
The distance from the amusement to jack's home is x (mile, x>0)
jack's family went to the amusement park at: 9 + x/60
On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph
they left the amusement park at: 20 - x/40
have the following equation:
(20 - x/40) - (9+ x/60) = 7
⇔ 4 = x/40 + x/60
⇔ x = 96
so the distance from the amusement park to jack's home is 96 miles
Will mark brainlist!! Nick’s Burgers is a fast-food restaurant that sells 140 burgers a day. If sales increase by 60%, how many burgers does the restaurant sell in a day?
A.56
B.148
C.200
D.224
Answer:
D- 224
Step-by-step explanation:
10% of 140 is 14
So then you multiply 14 by 6 to get 60%
then you add that to 140 to equal 224.
The correct statement is that if the sales of burgers at Nick's Burgers increases by 60%, the total sales per day will be increased to 224 burgers per day from 140 burgers per day.
What is Increased Sales?An increase in sales refers to as the positive shift in the sales of goods as compared to previous sessions during a given period of time, given that other factors vary.
The increase in sales will happen as a result of the strategies that may have been adopted by Nick or increase in the demand due to external factors.
The calculation of increased no. of burgers sold per day can be calculated by using the formula and putting the values given in the example as below,
increased sales = 224
So, the new sales of burgers per day is calculated as 224 per day.
Hence, an increase in sales of burgers at Nick's by 60% will result in sales of 224 burgers per day from 140 burgers per day.

With STEPS PLEASE AND NO TROLLING.
i edited the answer. hope it helps. if it isn't ryt tell me plz
Answer:
sin2x = [tex]\frac{30}{34}[/tex]
Step-by-step explanation:
Given
tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]
This is a right triangle with legs 3 and 5
Let the hypotenuse be h , then using Pythagoras' identity
h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )
h = [tex]\sqrt{34}[/tex]
Thus
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]
cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]
Hence
sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]

Answer: x = 5/7
Step-by-step explanation: 2x/3 + x/2 =5/6
To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.
for 2x/3 6÷3=2 2×2x=4x so that becomes 4x/6
for x/2 6÷2=3 3× (invisible) 1 = 3x, so that becomes 3x/6
combine 4x/6 + 3x/6 = 7x/6
Back to the original equation, substituting the calculated term:
7x/6 = 5/6 Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"
7x = 5 . Divide both sides by 7 to solve for x 7x/7 = 5/7
x = 5/7

Which expression is undefined?
A store sells a 33-pound bag of oranges for \$ 3.60$3.60 and a 55-pound bag of oranges for \$ 5.25$5.25. What is the difference between the price per pound for the 33-pound bag of oranges and the price per pound for the 55-pound bag of oranges? The difference is \$$ per pound.
Answer:
$0.014
Step-by-step explanation:
Given that :
Sales price of 33-pound bag of oranges = $3.60
Sales price of 55-pound bag of oranges = $5.25
Price per pound of 33-pound bag:
Sales price / number of pounds
= $3.60 / 33
= $0.109 per pound
Price per pound of 55-pound bag:
Sales price / number of pounds
= $5.25 / 55
= $0.095 per pound
Difference in price per pound of 33-pound bag and 55-pound bag of oranges :
$0.109 - $0.095
= $0.014
A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its release is modeled by y = − 16 t 2 − 2 t + 400 . How long will it take for the water to reach the ground? Round to one number after the decimal point.
Answer:
4.93 seconds
Step-by-step explanation:
The height y in feet of water t seconds after its release is given by the equation as follows :
[tex]y=-16t^2-2t+400[/tex]
We need to find the taken taken for the water to reach the ground. When it reach the ground, y will be equal to 0. So,
[tex]-16t^2-2t+400=0[/tex]
Above is a quadratic equation whose solutions can be calculated as follows :
[tex]t=\dfrac{-(-2)\pm \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=\dfrac{-(-2)+ \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}, \dfrac{-(-2)- \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=-5.062\ s\ \text{and}\ 4.93\ s[/tex]
Neglecting negative value.
Hence, it will take 4.93 seconds for the water to reach the ground
