Answer:

Step-by-step explanation:

Step 1: Add 24 to both sides.

/312

x−24+24=16+24

/312

x=40

Step 2: Multiply both sides by 312.

312*(

/312

x)=(312)*(40)

x=12480

ΔCAR has coordinates C (2, 4), A (1, 1), and R (3, 0). A translation maps point C to C' (3, 2). Find the coordinates of A' and R

shutvik [7]

Answer:

$A'= (2,-1)$ and $R'=(4,-2)$ under this translation.

Step-by-step explanation:

A translation in $R^{2}$ is a mapping T from $R^{2}$ to $R^{2}$ defined by $T(x,y) = (x + v_1,y+v_2)$ , where $v=(v_1,v_2)$ is a fixed vector in $R^{2}$ .

From the problem we know that $T(2,4)=(3,2)$ , so we need to find the values $v_1$ and $v_2$ such that $T(2,4) = (2 + v_1,4+v_2)=(3,2)$ , so $3=2 + v_1$ and $4+v_2=2$ , thus $v_1=1$ and $v_2=2$ .

Then $T(x,y) = (x + 1,y-2)$ and

$T(1,1)=(1+1,1-2)=(2,-1)=A'$

$T(3,0)=(3+1,0-2)=(4,-2)=R'$

Therefore $A'= (2,-1)$ and $R'=(4,-2)$ . The triangles CAR and C'Q'R' are shown in the figure below.

You know that a number 8 less than 60 is the number 52. so, you could rewrite your answer from the previous part as, "what numbe

svetoff [14.1K]

I'm a little confused by your question.

You said 60-8 = 52 which is true.

Then, you asked 4x = 52 in an integer form
x = 52/4
x = 13. (Is that what you're asking?)

I'm not sure if this helps, but please comment if you need any help! Hope this helps though! :D

Question 18<br> Calculate the mean 12, 2, 9, <br><br> 12, 10

kramer

Answer: 9

Step-by-step explanation:

first u have to add up all the numbers "12 + 2 + 9 + 12 + 10" and that's 45 then u have to divide by how many numbers there are, so there's 5 numbers. ur dividing "45/5" which is 9 so the mean is 9

At the end of a party, 3/4 cup of dip is left. Jim divides 4/5 of the leftover dip equally between 2 friends. How much dip does

Rudik [331]

First, we need to find the amount of dip that was divided amount the two friends.

We know that it is 4/5 of the left dip
therefore:
amount divided among the two friends = (4/5) x (3/4) = 3/5 of the original amount of dip.

This amount is divided among two friends,
therefore:
amount that each friend gets = (3/5) / (2) = 3/10 = 0.3 of the amount of dip
