Answer:
$66 for 6 cars.
Step-by-step explanation:
This is a rather simple problem. To find the answer you must divide 44/4= 11. Now knowing that Chris earns $11 per car if you multiply 11x6= 66 you can find out Chris makes $66 for 6 cars.
Answer:
210
Step-by-step explanation:
the % is there to try to throw you off. all you have to do is subtract 285 by 75
which is 210
i believe thats all you do. hope this helps!
Answer:
ABC = 30
Step-by-step explanation:
The two angles are complementary so they add to 90 degrees
2x+14 + x+7 = 90
Combine like terms
3x+21 = 90
Subtract 21 from each side
3x+21-21 = 90-21
3x = 69
Divide by 3
3x/3 = 69/3
x = 23
ABC = x+7 = 23+7 = 30
Answer:
(x-3)² + (y+2)² = 72
Step-by-step explanation:
center is halfway between (9,-4) and (-3,8).
average of x-coordinates = (9-3)/2 = 3
average of y-coordinates = (-4+8)/2 = -2
center: (3,-2)
length of diameter = √[(9-(-3))²+(-4-8)²] = √288 = 12√2
radius = 6√2
(x-3)² + (y+2)² = (6√2)² = 72
2x^2+20x=-38 divide both sides by 2
x^2+10x=-19, halve the linear coefficient, square it, than add that value to both sides of the equation, in this case add (10/2)^2=25...
x^2+10x+25=6 now the left side is a perfect square
(x+5)^2=6 take the square root of both sides
x+5=±√6 subtract 5 from both sides
x=-5±√6 (so answer c.)
