Answers

Answer:

Let x be the number of hits Ricky has. Then x+277 is the number of hits Pedro has. Adding Ricky's and Pedro's hits give you 2685 hits. Therefore, x+(x+227)=2685 2x+227=2685 2x=2408 x=1204 x+277 1481 Therefore, Ricky has 1204 hits and Pedro has 1481 hits.

Answers

Answer:

The three angles of a triangle always add up to 180.

Therefore, we have the equation:

55+20+x=180.

Solving for x, we get x=105.

So the answer is C.

Hope this helps! :D

180 because three angles of a triangle always add up to 180

Select the correct answer. Which image shows the correct position of on the number line? Which image shows the correct position of -2 1/2 on the number line? A. A B. B C. C D. D

Answers

Answer:

Option (A)

Step-by-step explanation:

Option A

Each small segment on the number line measure (0.5) unit.

Red point on the number line is 5 small segment distant from center 0.

So, the position of the point = 0.5 × 5 = 2.5

Since, the point is on the negative side position will be → -2.5

Option B

Position of the point = 0.5 ×3 = 1.5

Option C

Position of the point = 0.5 × 1 = -0.5 (negative sign shows the position of the point on the negative side of the number line)

Option D

Position of the point = 5 × 0.5 = 2.5

Answer the answer is A

How do we determine whether the decimal representation of a quotient of two integers, with the divisor not equal to zero, will terminate or repeat? Justify your reasoning.

Answers

Answer:

If the remainder we get is zero then it is terminating otherwise the number will be repeating.

Step-by-step explanation:

In order to find whether a number is terminating or repeating, divide the numerator with the denominator. If the remainder we get is zero, then it is a terminating number and if we do not get zero as remainder, it is a repeating number.

In division algorithm, when the remainder is zero, we get a terminating algorithm as the algorithm stops or terminates.

8 =100

Step-by-step explanation: since 5 and 7 are the same, if u slide the bottom up to the top, 1 and 3 would be the same as 5 and 7

2,4,6,and 8 are 180-80 which equals 100

Answer:

1, 3, 5, 7 = 80°

2, 4, 6, 8 = 100°

Step-by-step explanation:

1, 3, 5, and 7 are congruent to each other

2, 4, 6 and 8 are congruent to each other

1 + 2 + 3 + 4 = 360°

80° + x + 80° + x = 360°

160° + 2x = 360°

2x = 360° - 160°

2x/2 = 200°

x = 100°

Have a safe and happy new years

Step-by-step explanation:

Answer:

x = x

Step-by-step explanation:

The first step here is to use the distributive property to make the first equation back into a polynomial.

The way we do this is by multiplying each term on the inside of the parentheses by the -2 on the outside.

-2 x x = -2x

-2 x 3 = -6

So, our new equation reads: -2x - 6

-2x - 6 = -2x + 3 - 9

Our next step is to subtract the 9 from 3.

-2x - 6 = -2x - 6

We add 6 to each side

-2x = -2x

x = x

0 = 0

In step 1 there are three dots

In step 2 there are six dots

In step 3 there are eleven dots

We need to find the number of dots in step 4.

2+ 1=3

3 + 3 = 6

6 + 5 = 11

11+7=18

The sequence of odd numbers are added.

Hence, in step 4 there are 18 dots
