Answer:
r2 + h2 = t2
Step-by-step explanation:
pythagorean theorem : a2 + b2 = c2
Answer:
x ≤ 2
Step-by-step explanation:
Most of the properties of equality also apply to inequalities. The exception is multiplication (or division) by a negative number. An equation can be multiplied or divided by any number you like (except division by 0) and it will remain true. <em>An inequality must have the relation symbol reversed when multiplying or dividing by a negative number</em>.
Here, we don't run into that issue, because we can solve this by dividing both sides by the coefficient of x, which is +3.
(3x)/3 ≤ 6/3
x ≤ 2 . . . . . . . simplify
Answer:x=10/3
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
72 divided by 12 equals 6
Basically to solve this, you set both equations equal to each other and solve because the angles are the same.
5x+7=8x-71
isolate x by adding 71 to both sides and subtracting 5x from both sides
3x= 78
divide 78 by 3
x=26
