Answer:

Step-by-step explanation:

9x10 is nine ten times or ten nine times

9+9+9+9+9+9+9+9+9+9=90

10+10+10+10+10+10+10+10+10=90

An easy trick for doing anything muliplied by 10 is to just add an extra 0 on the end of the first number!

If S is the midpoint of RT , RS=8x+11 and ST =14x-1 find x

garri49 [273]

Answer:

From the given, we establish this relationship:

RS + ST = RT

RS = ST since S is the midpoint of RT

Thus, let's use RS = ST to find x,

By substituting the given expressions:

RS = ST

8x + 11 = 14x - 1

12 = 6x

x = 12/6

thus,

x = 2

kodGreya [7K]

Answer:

The inequality is

88<x<93

Step-by-step explanation:

The average of Shondra's test scores in physics is between 88 and 93.

Let me give out the meaning of some inequality symbols

<= Less than or equal to

>= Greater than or equal to

< Less than

> Greater than

Let the average score be x

In this case , the average score is between 88 and 93

The inequality is

88<x<93

15. Construct the slope-intercept form equation of the line passing through (-5,23) and (10,-5).

Radda [10]

Answer:

15y = -28 x + 205.

Step-by-step explanation:

Slope intercept form of equation is y = mx + c where m is slope and c is the y intercept.

Now slope of line passing through points (-5, 23) and (10, -5):

$m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} } = \frac{-5 -23}{10 + 5} = \frac{-28}{15}$

Now equation of line:

y = mx + c

substituting the value of m in above expression,

$y = -\frac{28}{15} x + c$

Now, since the line is passing through the point (-5, 23) therefore, x = -5 and y = 23. By substituting these values in above equation,

$23 = -\frac{28}{15} \times (-5) + c$

$23 = \frac{28}{3} + c$

$c = 23 - \frac{28}{3} = \frac{69 - 28}{3} = \frac{41}{3}$

So equation of line in slope intercept form:

$y = -\frac{28}{15} x + \frac{41}{3}$

Further solving,

15y = -28 x + 205.
