The answer would be 1,4, and 7. if you place each of those into the "3,71_" and then divide them by 3, you'll see that those three number make it divisible by three. its pretty much a guess and check question. you just have to test each answer choice.

olchik [2.2K]

Answer:

$V = \frac{4}{3} \pi R^{3}$ and

$v = \frac{4}{3} \pi r^{3}$

Step-by-step explanation:

Dawn wants to compare the volume of a basketball with the volume of a tennis ball.

Now, if the radius of the basketball is R and that of the tennis ball is r, then the formula that can be used to determine the volume of each ball will be

$V = \frac{4}{3} \pi R^{3}$ and

$v = \frac{4}{3} \pi r^{3}$

Now, dividing V by v we can compare the volume of the basketball and the tennis ball. (Answer)

Mr. Thompson had a balance of $283.12 in his checking account at the beginning of the month he wrote checks for $23.09 $7.56 $12

ryzh [129]

Account balance is $123.08

Step-by-step explanation:

Step 1: Balance in Thompson's account = $283.12. Calculate the total amount of checks Thompson wrote in the month.

Total amount of checks = $23.09 + $7.56 + $125.11 + $4.28

= $160.04

Step 2: Calculate his balance.

Account balance = $283.12 - $160.04

= $123.08

NEED ANSWER ASAP!!

erik [133]

Answer:

A=-2; B=-1

Step-by-step explanation:

3a - 2b + 4 =0

2a -5b -1 = 0

Let's multiple the top equation by 2, and the bottom by -3, and then use addition.

[3a - 2b + 4 =0]*2

[2a -5b -1 = 0]*(-3)

6a-4b+8=0

-6a+15b+3=0

Now add the two equations together:

11b + 11 = 0

Subtract 11 from both sides

11b = -11

Divide both sides by 11

b=-1

Substitute in the first equation:

3a - 2(-1) + 4 = 0

Simplify to get 3a+6 = 0

Subtract 6 from both sides to get 3a = -6

Divide both sides by 3 to get a=-2

No one helped so im asking for these 2 again

Answer:

3. Option No. 2:

6x + 2y = 22

3x + 3y = 18

4. Option No. 2:

$2.50

Step by step explanation:

4. 6x + 2y = 22

(3x + 3y = 18) * 2

- Negate

6x + 2y = 22

6x + 6y = 36

2y - 6y = 22 - 36

-4y = -14

y = -14/-4

y = 3.5

An order of onion rings = $3.50

- Substitute to find for x

6x + 2(3.5) = 22

6x + 7 = 22

6x = 22 - 7

6x = 15

x = 15/6

x = 2.5

An order of French fries = $2.50
