Answer:

he has 20 chickens

Step-by-step explanation:

i was testing with it. 20 dog legs divided by 4 (since dogs have 4 legs) equals 5. 5 times 4 (since 4 times the amount of dogs) is 20. then to check, 20 times 2 (since chickens have 2 feet) is 40. 20 dog legs plus 40 chicken legs. makes sense. again, 20 chickens.

Hey there!

This is a transversal with same-side interior angles. Same-side interior angles always add up to 180. So you add 9x-8 plus 80, which should equal 180. You then have your equation and then solve for x.

Let me know if you need more help. We just finished transversals in Geometry.

Answer: 24 minutes!

Step-by-step explanation: As mentioned, it can eat 45 ants per minute, How long would it take to eat 1,080 ants?

It's simple, just divide 1080 by 45 and when you divide it, the answer is 24!

In base 16, the numbers 10-15 are denoted by the letters a-f. So in the units place, we have

c₁₆ + e₁₆ = 12 + 14 = 16 + 10 = 1a₁₆

Carry the 1 to the next place value:

4₁₆ + c₁₆ + 1₁₆ = 4 + 12 + 1 = 16 + 1 = 11₁₆

Carry the 1:

d₁₆ + b₁₆ + 1₁₆ = 13 + 11 + 1 = 16 + 9 = 19₁₆

Carry the 1:

3₁₆ + 4₁₆ + 1₁₆ = 3 + 4 + 1 = 8₁₆

So, we end up with

3d4c₁₆ + 4bce₁₆ = 891a₁₆

Jiri age is 23

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

Alternate Interior angles are equal to each other;

8x - 4 = 60

Add 4 to both sides;

8x = 64

Divide both sides by 8;

x = 8

Answer:

Angle T = 39

Step-by-step explanation:

Triangle WXY is the same as triangle VTU

Therefore the angles are the same as well so because angle T and angle X are equal they both have the same value

Answer:

413_7

Step-by-step explanation:

Convert the following to base 7:

206_10

Hint: | Starting with zero, raise 7 to increasingly larger integer powers until the result exceeds 206.

Determine the powers of 7 that will be used as the places of the digits in the base-7 representation of 206:

Power | \!\(\*SuperscriptBox[\(Base\), \(Power\)]\) | Place value

3 | 7^3 | 343

2 | 7^2 | 49

1 | 7^1 | 7

0 | 7^0 | 1

Hint: | The powers of 7 (in ascending order) are associated with the places from right to left.

Label each place of the base-7 representation of 206 with the appropriate power of 7:

Place | | | 7^2 | 7^1 | 7^0 |  

| | | ↓ | ↓ | ↓ |  

206_10 | = | ( | __ | __ | __ | )_(_7)

Hint: | Divide 206 by 7 and find the remainder. The remainder is the first digit from the right.

Determine the value of the first digit from the right of 206 in base 7:

206/7=29 with remainder 3

Place | | | 7^2 | 7^1 | 7^0 |  

| | | ↓ | ↓ | ↓ |  

206_10 | = | ( | __ | __ | 3 | )_(_7)

Hint: | Divide the whole number part of the previous quotient, 29, by 7 and find the remainder. The remainder is the next digit.

Determine the value of the next digit from the right of 206 in base 7:

29/7=4 with remainder 1

Place | | | 7^2 | 7^1 | 7^0 |  

| | | ↓ | ↓ | ↓ |  

206_10 | = | ( | __ | 1 | 3 | )_(_7)

Hint: | Divide the whole number part of the previous quotient, 4, by 7 and find the remainder. The remainder is the last digit.

Determine the value of the last remaining digit of 206 in base 7:

4/7=0 with remainder 4

Place | | | 7^2 | 7^1 | 7^0 |  

| | | ↓ | ↓ | ↓ |  

206_10 | = | ( | 4 | 1 | 3 | )_(_7)

Hint: | Express 206_10 in base 7.

The number 206_10 is equivalent to 413_7 in base 7.

Answer:

$2.50 can be your constant because you will have to pay it once in order to bowl. $2.25 can be the coefficient of the variable. You can form the equation now. y is total price while x is how many games you can bowl.

Now that you have the equation, you can solve. Knowing that you have $9.25, just plug in that value in the y

Now, just simply solve for x and you will find the answer to the second part of the question. You will get x=3
