3x²-2x-5=0

x²-⅔x-5/3=0

x²-⅔x=5/3

x²-⅔x+(-⅓)²=5/3+(-⅓)²

(x-⅓)²=5/3+1/9

(x-⅓)²=16/9

(x-⅓)²=√16/9

Ben currently has $70 in his trip fund. He saves $27 for weekly expenses. Which equation can be used to determine the amount of the money (y), in dollars, that Ben has in his trip fund at the end of the x weeks?

Answers

Answer:

The equation y = 70-27x can be used to determine the amount of money.

Step-by-step explanation:

Given that:

Amount Ben has in his trip fund = $70

Amount save by Ben each week = $27

Number of weeks = x

Amount of money after x weeks = y

According to given statement;

y = 70-27x

Hence,

The equation y = 70-27x can be used to determine the amount of money.

If the length of a rectangle is given the expression 2 square root of 153 and the width is given by 4 square root of 68, which radical expression represents the perimeter of the rectangle

Answers

Answer:
C) 28√17
Step-by-step explanation:
The perimeter is twice the sum of the two given side lengths, so is ...
P = 2(L +W) = 2(2√153 +4√68)
= 2(6√17 +8√17) = 2(14√17)
P = 28√17 . . . . . matches choice C
_____
This is about simplifying radicals. The applicable rules are ...
√(ab) = (√a)(√b)
√(a²) = |a|
__
153 = 9×17, so √153 = (√9)(√17) = 3√17
68 = 4×17, so √68 = (√4)(√17) = 2√17
_____
Comment on the problem presentation
It would help if there were actually radicals in the radical expressions. We had to guess based on the spacing and the answer choices.
In any event, this problem can be worked with a calculator. Find the perimeter (≈115.45) and see which answer matches that. (That's what I did in order to verify my understanding of what the radical expressions were.)

Answer : -42

Explanation: 2^3+(2-10)-42
first you’re going to evaluate the exponent( or in other words simplify) which will give you :

8 + ( 2-10 ) - 42

then subtract which will give you :
8 + (-8) - 42

then Add

8 - 8 -42
and then find the total :
0 = -42

which gives you : -42.

A green rope is 60.5 m long. Each meter of the rope has a mass of
0.052 kg. What is the total mass of the green rope? Show your work.

Answers

Answer:

Answer:

4

Step-by-step explanation:

If you read it carefully then you'll get it :)

The total mass of the green rope will be the multiplication of length by per meter mass thus it will be 3.146kg.

What is multiplication?

Multiplication is the general procedure in mathematics in which we multiply two or more numbers by each other to find a new multiplied number.

Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.

As per the given,

Length of rope = 60.5 m

Mass per meter = 0.052 kg

Total mass = 60.5 x 0.052 = 3.146kg

Hence "The total mass of the green rope will be the multiplication of length by per meter mass thus it will be 3.146kg".

Write the pair of fractions as a pair of fractions with a common denominator |


3/10 and 2/5

1/3 and 3/4


THESE TWO ONLY!

Answers

Answer:

3/10 and 2/5 = 3/10 and 4/10

1/3 and 3/4 = 4/12 and 9/12

Step-by-step explanation:

For 3/10 and 2/5

* Find the lcm (least common multiple) of the denominators which are 10 and  

 5. The multiples of 10 are: 10, 20, 30 etc and the multiples of 5 are: 5, 10 15,

 etc. So, the lcm is 10. It is the smallest multiple that the denomitaotrs share.

* Next multiply the numerators (3 and 2) by whatever number you use to

  multiply the denominator by to get 10. For 3/10, the denominator stayed the

  same, so to get 10, you need to multiply 10 by 1. Do the same for the

  numerator. 3 x 1 = 3. So, the first factor pair is 3/10.

* The second factor pair is 2/5, so we are still using the lcm of 10. So, what

  do you need to multiply 5 by to get 10? The answer is 2. Now just multiply

  the numerator (2) by 2 and you get 4. The second factor pair is now 4/10.
