Answer:
Step-by-step explanation: < 180
Answer:
475 km
Step-by-step explanation:
(40 + 45 + 50 + 35 + 55 km + 50 *5 km)
<span>Unary minus: -8
</span><span>Multiple: 5 * (-8) = -40
</span><span>Multiple: 14 * (-40) = -560
The answer is -560

4x-10 and 7x-8 are supplementary angles and thus add up to 180 degrees.
Thus, 11x - 18 = 180 degrees.
Combining like terms, 11x = 198, and x = 18.
The two supplementary angles are 4(18)-10 and 7(18)-8, or 62 and 118 degrees.
