Answer:  -2, -1, -1, 0, -1, 1, -2, -1, -1, 0

Step-by-step explanation:

When you are looking at the problem

" -2, -1, -1, 0, -1, 1, -2, … Find the next 3 numbers in the sequence above. Describe the pattern."

you want to observe the pattern, now For example

1, 2, -1, -4 .. and so on

so there is a pattern here if looked at hard enough it goes 1 - 2 = -1 - -3 = -4

when you find the pattern it gets really easy.

Hope this helped!

Answer:

t = -1

Step-by-step explanation:

[tex]2t + 1 = 3t - 1 + 3[/tex]

Collect like terms and simplify

[tex]2t - 3t = - 1 + 3 - 1 \\ - t = 1[/tex]

Divide through by -1

[tex] \frac{ - t}{ - 1} = \frac{ 1}{ - 1} \\ t = - 1[/tex]

Answer:

t = - 2

Step-by-step explanation:

[tex]\frac{2t + 1}{3} = \frac{(3t-1) + 3}{4}[/tex]

First we need to cross multiply to get rid of the division to make it easier to solve.

Multiply 2t+1 by 4 and (3t-1) + 3 by 3

4 ( 2t + 1 ) = 3 ( ( 3t - 1 ) + 3 ) On the right we need to combine terms.

4 ( 2t + 1 ) = 3 ( 3t - 1 + 3 )

4 ( 2t + 1 ) = 3 ( 3t + 2 )   Multiply

4 * 2t + 4 * 1 = 3 * 3t + 3 * 2     Remember order of operations. Multiplication comes before addition and subtraction.

4 * 2t + 4 * 1 = 3 * 3t + 3 * 2

8t + 4 = 9t + 6      Subtract 8t from each side

8t - 8t + 4 = 9t - 8t + 6

4 = t + 6       Subtract 6 from each side

4 - 6 = t + 6 - 6

4 - 6 = t

- 2 = t

Answer:

x = 36 degrees, the smaller angle.

4(36) = 144 degrees, The larger angle.

36 + 144 = 180 degrees.

Cleomenius.

Answer:

x = 36 degrees, the smaller angle.4(36) = 144 degrees, The larger angle.36 + 144 = 180 degrees.

Step-by-step explanation:

(1)adjacent- two non-overlapping angles that share a common vertex and a common side

(2)the non-common sides are opposite rays.

(3)adds up to 180

There are 24 hours in a day and so 15 hours is 15÷24=58 of a day. Since the rig drills 60 feet underground in a day, in 58 of a day it will drill

(58 days)×(60feetday)=3008 feet.

So the rig will have drilled 3008=37.5 feet underground in 15 hours.

The rig drills 60 feet underground per day so to find how long it has been running to go 143.6 feet underground, we need to calculate

(143.6 feet)÷(60feetday)=143.660 days.

This is about 2.4 days. Alternatively, it is 57.44 hours

We know that the rig drills at a constant rate, so there is a proportional relationship between the two quantities d, the height to which the drill has dug, and t, the number of days the drill runs. It drills at -60 feet per day, so we can represent this relationship with the equation:

–60t=d

Since 15 hours is 1524=58 days, we can use the equation to find d:  

–60⋅58=d

Since the depth is the same whether we think of it as a positive depth below the surface or a negative height above the surface, we can find this value by multiplying 60⋅58=37.5  and then noting that the sign must be negative if we are representing positions below the surface of the earth by negative numbers. So d=–37.5 and the drill will be at height -37.5 feet after 15 hours.

Likewise, if we know the drill has dug to -143.6 feet, we can use the equation again, this time to find t:  

−60t=−143.6

so t=(−143.6)÷(−60). Since the amount of time would be the same if we were working with positive feet below the surface of the earth and a drill rate of 60 feet per day below the earth surface, we can find this value by dividing 143.6÷60, which is about 2.4 days.

Question

Which list of integers is in order from greatest to least?

a) -11, -18, -33, 9, 24

b) -33, 24, -18, -11, 9

c) 24, 9, -33, -24, -11

d) 24, 9, -11, -24, -33

Answer:

d) 24, 9, -11, -24, -33

Step-by-step explanation:

The question asked us which list of integers is in order from greatest to least. This means, we should arrange the integers in descending order from the highest to the least or lowest number.

24< 9< -11< -24 < -33

Hence, from the greatest to the least =

24, 9, -11, -24, -33

Option d), is correct.

Answer:

g = 14

Step-by-step explanation:

g + 3 = 17

minus 3 from both sides

g = 14

Answer:

j=4

Step-by-step explanation:

5j+15=12j-13

Answer: j = 4

Step-by-step explanation:

5j + 15 = 12j - 13

5j = 12j - 28                  Subtract 15 from both sides        

-7j = -28                        Subtract 12j from both sides

j = 4                               Divide -7 from both sides

Step-by-step explanation:

Let the first part be x. Then,

the second part will be (10000-x).

So, According to question,

(10% of x) + { 7% of (10000-x)} = 805

(10/100*x) +{7/100*(10000-x)} = 805

(x/10) + (70000-7x/100) = 805

Then,

We will take the lcm of 10 and 100 which is 100 and then add both the fractions.

Solution:

10x + 70000-7x/ 100 = 805

3x + 70000/100 = 805

3x + 70000 = 805*100

3x + 70000 = 80500

3x = 80500-70000

3x = 10500

x = 10500/3

x = 3500

So the first part is 3500.Then,

the second part will be (10000-3500)

= 6500

Answer:

-3(2x+3)=21 does not become -6x+9=21 because wrong foiling.

Step-by-step explanation:

When you distribute -3 with 2x+3 you multiply both values by -3.

-3*2x = -6x

-3*3 = -9 <- This is where the error is. It's -9, not +9.

Step-by-step explanation:

Construction: To copy angle CAB.

i. On angle CAB, with center A and any radius; draw an arc to intersect CA at E and AB at F.

ii. Place a divider at EF to copy the angle.

iii. Draw a separate straight line MN of approximate length to AB.

iv. Mark point P on MN. Place the divider with radius EF at P to mark Q.

v. Draw a line LM from M through Q.

vi. Therefore, angle CAB would be equal to angle LMN.

Answer:

81 blue cars

Step-by-step explanation:

Total Cars = 90

How much % are blue = 90

=> 90 x 90/100 = How many cars are blue

=> 8100/100 = the number of cars that were blue

=> 81 = cars that were blue.

There 81 blue cars in the parking lot.

Answer:

They subtracted 2x from both sides.

Step-by-step explanation:

They removed 2x from each side because in order to find x it will have to be removed on one side. Since 2x - 2x = 0 it is 2x is out of the equation for the right side and on the left side -2x -(-4x) = -6x which means that there is one x variable left in the equation thus making it solvable.

Answer:

37/200

Step-by-step explanation:

.185= 185/1000

reduce to- 37/200

Hope this helps.

Step-by-step explanation:

1. We can see that the two vertical lines are parallel. Since one angle is 80º, then the other side should be 100º, since the straight line is 180º.

2. If the angle on the right is 80º, then that means the angle with y and 40º add up to 100º.

3. 100º - 40º = 60º.

Our final answer: y = 60º

Answer:

t = 1.15 seconds.

Step-by-step explanation:

The pumpkin is dropped from the height of = 64 feet.

Now we have to find the time taken to reach the pumpkin on ground. Use the below formula to find the time taken.

H = ½ gt^2

H = height

g = 9.8 (always contant )

t = time taken.

Now insert all the values in the formula.

H = ½ gt^2

64 = ½ ×9.8× t^2

(64×2) / 9.8 = t^2

t = 1.15 seconds.

The correct answer is:

A circle divided into 5 equal parts. 2 parts are shaded.

Step-by-step explanation:

To determine the fraction less than three-fifths, let us convert the word problems into figures and compare the values:

[tex]Three-fifths = \frac{3}{5} = 0.6[/tex]

a) A circle divided into 5 equal parts. 4 parts are shaded (four-fifths)

[tex]Four-fifths = \frac{4}{5} = 0.8\ (more\ than\ three-fifths)[/tex]

b) A circle divided into 5 equal parts. 2 parts are shaded. (two-fifths)

[tex]Two-fifths = \frac{2}{5} = 0.4\ (less\ than\ three-fifhs)[/tex]

c) A circle divided into 5 equal parts. 6 parts are shaded = [tex]\frac{6}{5} = 1.2[/tex] (more than three-fifths)

d) A circle divided into 10 equal parts. 8 parts are shaded [tex]= \frac{8}{10} = 0.8\ (more\ than\ three-fifths)[/tex]

Therefore, the fraction less than three-fifths = A circle divided into 5 equal parts. 2 parts are shaded. (two-fifths)

A circle divided into 5 equal parts. 2 parts so the answer is B
