Previous question Rational numbers prior question delete your full name you accidently wrote in your question for rational numbers by pressing edit icon answered here so your edit is possible ok! Answer is -2t +7t = 5t Step-by-step explanation: question asks for addition only (4t-6t= -2t)+(8t-1t=7t) This question on page = 1) At 2:16 p.m.= -180ft - 40ft = -220ft 2) At 2:17 p.m = -175ft-40ft= -115ft 3) At 2:18 p.m. = -185ft - 40ft = -225ft 4) The difference is show your work by reversal 2:18-2:15 = 3 minutes so the distance is also reversed at (-225) - (-40 )= -225 + 40 = -175

Step-by-step explanation: This is minus - number minus- number = minus number counting bkwards but when when we subtract two minus number with another minus it becomes a plus + just between the brackets see question 4 brackets use. The work is using brackets for question 4.

motikmotik

Answer:

During the first year he had an annual interest of 12%, and in the second year of 25%

Step-by-step explanation:

To calculate the interest of the first year:

(Initial capital of the first year / final capital of the first year) - 1 = interest of the first year

(300/336) - 1 = 0.12 = 12%

To calculate the interest of the second year:

(Initial capital of the secondyear / final capital of the second year) - 1 = interest of the second year

(336/420) - 1 = 0.25 = 25%

At a school concert,the orchestra plays 8 songs that are 4.25 min long and 3 songs that are twice as long as each of the others.

Kazeer [188]

Answer: 59.5 minutes.

Step-by-step explanation:

1. You have the following information given in the problem above:

- 8 songs are 4.25 minutes long.

- 3 songs are twice as long as each of the others.

2. Therefore, the total time of 8 songs is:

$(8)(4.25min)=34min$

3. And the total time of the 3 songs is:

$(2)(3)(4.25min)=25.5min$

4. Therefore, you have that the result is:

$34min+25.5min=59.5min$

to solve the equation |x-9|=0.5x, kiana graphed the functions f(x)=|x-9| and g(x)=0.5x on the same set of coordinate axes. She t

Pani-rosa [81]

Answer:

The answer is the option D

$f(6)=g(6)$ and $f(18)=g(18)$

Step-by-step explanation:

we have

$f\left(x\right)=\left|x-9\right|$

$g(x)=0.5x$

we know that

The solution of the system of equations is the intersection point both graphs

Using a graphing tool

see the attached figure

The solution are the points $(6,3)$ and $(18,9)$

therefore

The solution of the equation $\left|x-9\right|=0.5x$ are

$x=6, x=18$

so

For $x=6$

$f\left(6\right)=\left|6-9\right|=3$

$g(6)=0.5(6)=3$

$f(6)=g(6)$

For $x=18$

$f\left(18\right)=\left|18-9\right|=9$

$g(18)=0.5(18)=9$

$f(18)=g(18)$

therefore

$f(6)=g(6)$ and $f(18)=g(18)$ because the intersection points are common points for both graphs

74.5 and 64.5

Step-by-step explanation:

Women midpoints:

54.5 - 0%

64.5 - 30%

74.5 - 35% (most pulse rates from women)

84.5 - 29%

94.5 - 2%

104.5 - 2%

114.5 - 0%

124.5 - 2%

Men midpoints:

0 - 0%

54.5 - 15%

64.5 - 43% (most pulse rates from men)

74.5 - 20%

84.5 - 20%
