Answer:
7.8
Step-by-step explanation:
1. 5^2 +6^2=x^2
2. 25+36 = x^2
3. 61=x^2
4. = 7.8
A. 170 students out of the 230 students love both biking and skating (to make it easier, the percentage is about 0.74).
I am sorry if I cannot solve the other half of your question
Answer:
all squares are quadrilaterals
Knowing it has to be perpendicular, the slope of the new line has to be -2.
y = -2x + b
Plug the coordinate pair into the equation.
10 = -2(7) + b
10 = -14 + b
24 = b
So the final equation for the line is...
y = -2x + 24
Answer:
Step-by-step explanation:
<u>Goal</u>
<u>Given</u>
<u>Step</u><u> </u><u>1</u>
- Isolate x by adding 2 to both sides.
<u>Step</u><u> </u><u>2</u><u> </u><u>(</u><u>Optional</u><u>)</u>
- We check the answer by substituting x = 4 in the equation.
The equation is true for x = 4. Hence, the solution is x = 4.
