8(3a + 7) = 8+3(6a - 6)

Answers

Answer 1

Answer:

Answer:

a=11

Step-by-step explanation:

8(3a + 7) = 8+3(6a - 6)

24a+56=8+18a-18

24a-18a+56=8+18a-18a-18

6a+56=8-18

6a+56=-10

6a+56-56=-10-56

6a=-66

6a/6=-66/6

a=-11

Answer 2

Answer:

Answer:

a = -11

Step-by-step explanation:

8(3a + 7) = 8+3(6a - 6)

= -11

A bird catches a fish and flies 100 yards in a straight line at an angle of elevation x degrees from the ground. After flying for 100 yards the bird drops the fish. The fish lands at a spot y yards horizontally from where the bird caught it. What is x?A.)cos -1 y/100

B.)sin -1 y/100

c.)tan -1 y/100

D.)cos -1 100/y

E.)sin -1 100/y

Answers

Answer: Hello there! The correct answer is A.

If the bird flies 100 yards with an angle of elevation of x from the ground, then you could think this as a tringle rectangle, where the hypotenuse is 100 yards, the opposite cathetus is sin(x)*100 and this represents the height at which the bird dropped the fish, not really useful here.

The adjacent cathetus us 100*cos(x), in this case, you are calculating the displacement adjacent to them (because the angle is with respect to the ground) and knowing that the fish lands in a translated y yards horizontally we could write: y = cos(x)*100

now we want to isolate x:

y/100 = cos(x)

arcos(y/100) = arcos(cos(x)) = x

x = arcos(y/100) (or cos-1(y/100) like in the option A)

then, knowing the value of y, we could obtain the angle x with that equation.

The angle of elevation can be solved using B.)sin -1 y/100, which makes use of trigonometric functions.

Answer: x=-2

Step-by-step explanation:

First subtract 4 from both sides

Sqrt(x+3)=1

Then square both sides

X+3=1

Then subtract 3

X=-2

The difference of 9 times a number and 2 is 67.Which equation below can be used to find the unknown number?

Answers

the total is 67 so you would write that out
67=
Next you can write out 9 times a number. you can let that unknown number be n(you can use any variable you like). So now you would have
67=9n
You still have to subtract 2 from the 9n so plug that in
67=9n-2
Your answer would be 67=9n-2

Find two consecutive numbers whose sum is 117

Answers

So,

x + y = 117
y = x + 1
x + x + 1 = 117

Collect Like Terms
2x + 1 = 117

Subtract 1 from both sides
2x = 116

Divide both sides by 2
x = 58

y = x + 1

y = 58 + 1

y = 59

The 2 consecutive integers are 58 and 59.

$n+n+1=117\n2n=116\nn=58\nn+1=59$

These numbers are 58 and 59.
