Answer:
Equation is x-1=3x-11
x= 5

Explanation:
BC and BD are congruent. I forgot the name of the theorem but it involves proving the bisected angle’s triangles congruent.
So here’s my attempt at that:
Angle: Angle BAC and BAD are congruent as they are bisected.
Angle: The right angles are congruent.
Side: BA is congruent for both triangles. The triangles are congruent by AAS, so BC and BD must be congruent.
BC=BD
x-1=3x-11
10=2x
x=5

Are the two figures congruent?

geniusboy [140]

Answer:

No, because the reflection of ABC is not congruent to A’B’C’.

Step-by-step explanation:

we know that

The rule of the reflection across the line y=x is equal to

(x,y) -------> (y,x)

so

A(-6,6) -------> A'(6,-6) ----> is ok

B(-3,3) ------> B'(3,-3) ----> is ok

C(-8,2) ------> C'(8,-2) ----> is not ok ( is not a reflection acros the line y=x)

therefore

The triangles are no t congruent, because the reflection of ABC is not congruent to A’B’C’

Point Q is the midpoint between points P and R on a number line. If the coordinate of point Q is 6 and the coordinate of point P

nekit [7.7K]

Answer:

$R = 17$

Step-by-step explanation:

Given

$P = -5$

$Q = 6$

<em>Midpoint: Q</em>

Required

Determine R

Since Q is the midpoint, then

$Q = \frac{1}{2}(P + R)$

Substitute values for P and Q

$6 = \frac{1}{2}(-5 + R)$

Multiply both sides by 2

$12 = -5 + R$

Add 5 to both sides

$12 + 5 = -5 + 5 + R$

$17 = R$

$R = 17$

Cierra has three more than 1/2 as many purses as Asia defined a variable and write an expression to represent the number of purs

Ray Of Light [21]

Answer:

The equation representing the number of purses Ceirra has is $c=3+\frac{1}{2}\times a$ .

Ceirra has <u>9</u> purses in her collection.

Step-by-step explanation:

Given,

Cierra has three more than 1/2 as many purses as Asia.

Solution,

Let the number of purses Cierra has be 'c'.

And also the number of purses Asia has be 'a'.

Now according to question, Cierra has 3 more than 1/2 purses as Asia has.

Framing in equation form, we get;

$c=3+\frac{1}{2}\times a$

Hence The equation representing the number of purses Ceirra has is $c=3+\frac{1}{2}\times a$ .

Now we solve the equation;

Since Asia has 12 purses.

So we substitute the value of 'a', and get;

$c=3+\frac{1}{2}\times12=3+6=9$

Hence Ceirra has <u>9</u> purses in her collection.
