How many soulutions are there to 8 (x-3) =8x-24
Nat2105 [25]

Answer:

Yes

Step-by-step explanation:

Answer:

infinitely many solutions.

Step-by-step explanation:

The given equation is 8(x-3)=8x-24

Distribute 8 over the parenthesis in the left hand side

8x-24 = 8x-24

Group the like terms

8x-8x=-24+24

Combine like term

0 = 0

We got a true result, 0 = 0.

Hence, the equations have infinitely many solutions.

Brian just bought 9 bags of 14 cookies each. He already had 8 cookies in a jar. How many cookies does Brian have now?
RUDIKE [14]

Answer: 134 cookies

Step-by-step explanation: First we want to find the total amount of cookies Brain bought. Simply multiply 14 x 9 to find the total amount of cookies bought.

14 x 9 = 126 cookies.

Since Brian already had 8 cookies in the jar, we will simply add the new amount of cookies he bought to the cookies in the jar left.

126 + 8 = 134 total cookies that Brain has now.

In the first 8 overs the bowling rate of a cricketer is 4.5, In the last two over by giving how much run the bowling rate will b
jeyben [28]

Answer:

In the last two overs, the bowler gave 14 runs.

Step-by-step explanation:

The bowling rate of 4.5 in the first 8 over means he gave 32.5 runs.

i.e.

Score given in first 8 overs = 4.5 × 8 = 36

Given that the bowling economy 5 at the end of 10 overs means the bowler must have given 10 × 5 = 50 score in the total 10 overs.

so, subtract 36 from 50 to get the score he will be giving in the last two overs.

i.e. score given the last two overs = 50 - 36 = 14

Therefore, in the last two overs, the bowler gave 14 runs.

Show that the points (3,1) and (1,3) are the same distance from the origin
Phantasy [73]

Let's use the distance formula to find the distance between the origin and each of the points. We can use this to show that the distances are the same. Remember that the distance formula is:

\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

  • (x_1, y_1) is one point
  • (x_2, y_2) is the other point that you are trying the distance to

First, let's find the distance between the points (3, 1) and the origin, (0, 0). We will call this distance D_1.

D_1 = \sqrt{(3 - 0)^2 + (1 - 0)^2}

D_1 = \sqrt{3^2 + 1^2}

D_1 = \sqrt{10}


Next, let's find the distance between (1, 3) and the origin, (0, 0). We will call this D_2.

D_2 = \sqrt{(1 - 0)^2 + (3 - 0)^2}

D_2 = \sqrt{1^2 + 3^2}

D_2 = \sqrt{10}


We can see that D_1 = D_2, or that the distances are the same. ✔︎
