Answer:
x =-4
Step-by-step explanation:
3x − 7 = −19
Add 7 to each side
3x − 7+7 = −19+7
3x = -12
Divide by 3
3x/3 = -12/3
x =-4
Answer:
Step-by-step explanation:
X = the number of students in Megan's class
4/7 X = the number of girls in the class (G)
4/7 * 2/3 = the number of girls in the class who participate in sports
4/7 * 2/3 = 8/21 of girls in Megan's class participate in sports
The way I did this was determine the proofreaders’ page/hour rate. 200/6 is 33.33, while 200/9 is 22.22. 55.55 in total. 55.55/hour, combined, means that this hourly rate would need to multiply to fit in three hours. Thus, we multiply 55.55 by three, giving us 166.65. This is not two hundred, meaning you need more time, or better proofreaders.
Answer:
3√5 or ≈ 6.71
Step-by-step explanation:
The Distance Formula is d = √((x2-x1)² + (y2-y1)²)
<u>Given Points:</u> (-3, 2) and (0, -4)
<u>Points:</u> (x1, y1) and (x2, y2)
<u>Find the difference between coordinates:</u>
(x2 - x1) = (0 - (-3)) = 3
(y2-y1) = (-4 - 2) = -6
<u>Square the results and sum them up:</u>
(3)² + (-6)² = 9 + 36 = 45
<u>Now Find the square root and that's your result:</u>
Exact solution: √45 = 3√5
Approximate solution: 6.7082
