Answer:

x = -7

Step-by-step explanation:

-2x + 1 = -x + 8

* isolate the variable using inverse operations *

step 1 add 2x to each side

-2x + 2x cancels out

-x +2x = x

now we have 1 = x + 8

step 2 subtract 8 from each side

8 - 8 cancels out

1 - 8 = -7

we're left with x = - 7

Answer:

-12a³b²/(6ab²)=-2a^(3-1)=-2a²

Since ab don't have any values yet, you must break it down now knowing ab doesn't equal 0.

Y = 10

I hope it's helps you

Answer:

y = 10

Step-by-step explanation:

So, we can use the external angle as the measurement of the distant angles. In other words,

4y + 7y + 6 = 116

11y + 6 = 116

11y = 110

y = 10

Answer:

x ≈ -0.14

Step-by-step explanation:

6(4x + 5) = 3(x + 8) + 3

24x + 30 = 3x + 24 + 3

24x + 30 = 3x + 27

21x + 30 = 27

21x = -3

x = [tex]\frac{-3}{21}[/tex]

x = [tex]-\frac{1}{7}[/tex]

Answer:

64.3 miles ( D)

Step-by-step explanation:

Circular orbit height ( from the center of the earth ) = 100 mile

angle between satellite and earth = 50°

escape velocity = √2 * 17500 =  24748.73 miles /hour

distance between surface of earth and satellite

x = cos ∅

∴ Cos ∅  = x / 100

x = cos 50° * 100   ≈ 64.3 miles

Answer:

i cant rlly see the question bc its cut out but i yhink its 8

Step-by-step explanation:

total Amount of Marbles in the bag is:

5 + 3 = 8

So, since there are 5 Red marbles, the probability of drawing one is 5 / 8.

Now that you pulled that marble out, you have 7 marbles total left in the bag, 4 of those are read (5 originally, minus the one you took out.

So, the probability of the second round is 4/7.

To find the overall probability, you multiply those probabilities together:

4/7*5/8 = 20/56

Answer:

B. Ferrari and Jaguar is the answer

Step-by-step explanation:

length of 1st piece = x inch

length of 2nd piece = 3x inch

length of 3rd piece = 4x inch

x + 3x + 4x = 56

8x = 56

x = 7

Thus,

length of 1st piece = 7 inch

length of 2nd piece = 3 × 7 = 21 inch

length of 3rd piece = 4 × 7 = 28 inch

Step-by-step explanation:

27 divided by 3 is 9, so planting one violet takes 9 minutes, if they spend 45 minutes planting them you divide 45 by 9 and get 5.

Answer: No

Step-by-step explanation:

The number of yards fencing the homeowner need to surround the entire lot is 78.5 yards. Therefore, the option D is the correct answer.

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre. A meridian is any great circle passing through a point designated a pole.

Given that, a house is located at the center of a circular lot, exactly 25 yards from the edge of the lot.

Here, d = 25 yards

Radius = 25/2 = 12.5 yards

We know that, the circumference of a circle = 2πr

= 2×3.14×12.5

= 78.5 yards

Therefore, the option D is the correct answer.
