pogonyaev

Answer:

41/6

Step-by-step explanation:

-12+81=-1+6(2a-2)

first distribute:

-12+81=-1+12a-12

combine like terms:

<u>-12+81</u>= <u>-1</u>+12a<u>-12</u>

69=-13+12a

add -13 with 69:

82=12a

divide 82 and 12:

82/12= 41/6

2. Given: mZABD = rº and mZACB = yo
Ede4ka [16]

Step-by-step explanation:

the angle ABC = 180 - x, as ABD and ABC are complementary angles on top of the bottom line : all angles around a point on one side of a line are always adding up to 180 degrees.

but because we also know that the sum of all angles in a triangle is 180 degrees too, we can say

180 = ACB + ABC + CAB

180 = y + 180 - x + CAB

0 = y - x + CAB

x = y + CAB

x - y = CAB

therefore, the second answer option is correct.

On the freeway, it is unsafe to drive too slowly or too quickly. The safest driving speeds on the freeway near Allan’s town were
meriva

Answer:

59.0 miles per hour

Step-by-step explanation:

When you have an equation with an absolute value, you must consider two options: one with a positive result and another one with a negative result.

x-55 = 4.2\\x = 4.2 + 55\\x = 59.2\\\\And\\\\x-55 = -4.2\\x=-4.2 + 55\\x = 50.8

In this case you need the maximum safe driving speed which is 59.2 miles per hour

The sum of the circumference and diameter of a circle is 116 cm. Find its radius
AleksAgata [21]

Answer:

Step-by-step explanation:

A.t.q,

2πr+2r=116 cm

2r(π+1)=116 cm

2r(22/7+1)=116 cm

2r(22+7/7)=116 cm

2r=116×7/29

2r=28 cm

r=28/2

r=14 cm

Thank you
