In the figure below, AMNO
NeX [460]

Given:

\Delta MNO\cong \Delta PQR

To find:

The length of QR.

Solution:

We have,

\Delta MNO\cong \Delta PQR

Then, MN=PQ                 (CPCTC)

10=4x-2

10+2=4x

12=4x

Divide both sides by 4.

\dfrac{12}{4}=x

3=x

Similarity,

MO=PR            (CPCTC)

2y+3=21

2y=21-3

2y=18

Divide both sides by 2.

y=9

Now,

x+y=3+9

x+y=12

Therefore, the correct option is d.

Can someone please help
Leona [35]

Answer:

each hamburger costs $3.50

Step-by-step explanation:

he spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equaton,

2.50 + 3h = 13 now solve for x

-2.50           2.50

3h = 10.50

h=3.50

check:

2.50+3(3.50)=13

2.50+10.50=13

13=13

What is the solution to the inequality?
Alexxx [7]

Answer:

Oc. x>11

Step-by-step explanation:

Subtract 4 from 4 which will give you 0, then subtract 4 from 15 which should give you 11. x is still greater than 11. You don't switch the signs unless you're dividing or multiplying by a negative number. Hope this helps.
