1,925 is close to 2,000

so 2,000 x 7 = 14,000

1,925 x 7 = ?

5 x 7 = 35

20 x 7 = 140

900 x 7 = 6,300

1,000 x 7 = 7,000

so 7,000 + 6,300 + 140 + 35 = 13,475 and 13,475 is close to 14,000 or 13,500 or 13,470.

Hope this helps even though a little confusing! ;D

$-0.2(x-20)=44-x\qquad\text{use distributive property}\\\\-0.2x+4=44-x\qquad\text{subtract 4 from both sides}\\\\-0.2x=40-x\qquad\text{add x to both sides}\\\\0.8x=40\qquad\text{divide both sides by 0.8}\\\\x=\dfrac{40}{0.8}\\\\x=\dfrac{400}{8}\\\\\boxed{x=50}$

Write, in slope intercept form, the equation of the line that passes through (8, -9) and has a slope of -5/4.

dezoksy [38]

Answer:

The equation in the slope-intercept form will be:

$y=-\frac{5}{4}x+1$

Step-by-step explanation:

Given

slope = m = -5/4

point = (8, -9)

As we know that the equation of a line in point-slope form is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -5/4 and point = (8, -9)

$y-\left(-9\right)=\frac{-5}{4}\left(x-8\right)$

$y+9=\frac{-5}{4}\left(x-8\right)$

Writing the equation in slope-intercept form

$y=mx+b$

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

$y+9=\frac{-5}{4}\left(x-8\right)$

subtract 9 from both sides

$y+9-9=\frac{-5}{4}\left(x-8\right)-9$

$y=-\frac{5}{4}x+1$

Therefore, the equation in the slope-intercept form will be:

$y=-\frac{5}{4}x+1$

first, measures the triangle's angles. They are all 60 degrees. Then, measures the sides. Side 1 is 6 cm long. Side 2 is also 6

jenyasd209 [6]

Answer:

The correct answer is 6 cm.

Step-by-step explanation:

The measure of all angles of the triangle is given to be 60 degrees. This invariably means we are talking about an equilateral triangle as all angles of an equilateral triangle are equal.

Also all sides of an equilateral triangle is known to be equal. Therefore the measure of all sides of the concerned triangle are equal.

Given the measure of two length of sides are 6 cm respectively.

Therefore the length of side 3 is 6 cm, equal to the other two sides.
