Solve these 2 questions

1. Solve for X. X^3 + 10 x 23 = 355

2. If bob gains 5 apples a day and Billy gains twice as many apples as bob but loses 3 on the 3 day of every month than how many apples would than have gained in total over the course of 10 decades

Answers

Answer 1
1. x^3 + 10 x 23 = 355
10 x 23 = 230
355 - 230 = 125
cube root of 125 is 5
So,
x = 5

2.
Bob = 5 per day for 100 years
Billy = 10 per day for 100 years minus 3 every month

Bob = 5 x 365 = 1,825 per year
Billy = 5 x 2 x 365 = 10 x 365 = 3,650 per year without reduction of 3 apples per month
12 months per year x 3 apples = 36 so 3,650 - 36 = 3,614 apples per year so billy = 3,614 apples per year

Bob = 1,825 x 100 = 182,500 apples after 10 decades
Billy = 3,614 x 100 = 361,400 apples after 10 decades
So,
Bob = 182,500 apples
Billy = 361,400 apples
Not including leap years

Including leap year would =
Bob = about 182,625 apples
Billy = about 367,650 apples

Because leap year is every 4 years and 100 years / 4 years = 25 years so
Bob = 1,830 x 25 + 1,825 x 75 = 182,625 apples
Billy = 3,624 x 25 + 3,614 x 75 = 367,650 apples

Sorry if it looks complicated
Hope this helps ;)

Chicken is normally $2.15/lb. but if you purchase 26 pounds for $41.34, how much do you save per pound?

A. $0.19
B. $0.26
C. $0.56
D. $0.79

Answers

Answer: C

Step-by-step explanation: If you take $41.34 divided by 26 you get $1.59. Then, take $2.15-$1.59.

The answer is c

Explanation: 41.34 divided by 26 is 1.59 so since we know this next you have to subtract 2.15 by 1.59 then you should get 0.56 as your answer.

Solve for x in the equation below.

(x – 2) = –14(x – 8)

Select the correct answer.
A. x = 0
B. x = –513
C. x = –315
D. x = 315

Answers

How to solve: (x-2) = -14(x- 8)

X times 2 is 3x so write 3x = -14 + 8x to simple it. Then u to the complete other

-14 minus on both sides then do 3x = 11 then u divide 3 on both sides cross out 3 and 3 and divide 3 by 11 then you’ll get x= 3.6

Answer:

Step-by-step explanation:

First of all, fix the bracket on the R.H.S

x- 2 = -14x + 112

Collect like terms: Bring x to one side and variables to the other side.

x+14x = 112 + 2

15x = 114

Divide both sides by 15

x = 114/15

x = 7.6

Which expression is NOT equivalent to? :

-15f - f + 10g -2g + 8f

A. -8(f + g)
B. 8g - 8f
C. -8f + 8g
D. 8(g-f)

Answers

Answer:

A. -8(f + g)

Step-by-step explanation:

     First, let us simplify -15f - f + 10g -2g + 8f

Given: -15f - f + 10g -2g + 8f

Combine like terms:  -8f + 8g

     Now that we have it simplified, we can tell that our answer will not be B or C.

     I can tell you that the answer to this question is A because -8 times g is -8g and we need it to be positive.

The perimeter is 26 bc x=5 so 5+2 is 7 the opposite side is congruent which gives you 7 again and then 5+1 is 6 so 7+7+6+6=26

The equation is 61 bc x=3 so

7x3 is 21

2x3 is 6

21-6 is 15

8+6 is 14

Reduce the fraction by 3

That leaves you with 5+4x14

4x14 is 56

56+5 is 61

A jet travels 500 miles in 2 hours. At this rate, how far could the jet fly in 11 hours? what is the rate of speed of the jet?

Answers

Answer:

The rate of speed is 250 mph. That means the jet can travel 2,750 miles in 11 hours.

Step-by-step explanation:

The rate of speed is 500 divided by 2 to get the speed for one hour. Then you take that to get the distance covered in 11 hours by taking 500 divided by 2, which is 250, and multiplying that by 11.

Answer: 500 divided by 2 = 250 miles per hour. 250 x 11 = 2750 miles in 11 hours.
