I need some one to answer this the second they see it
Alchen [17]

Answer:

12

Step-by-step explanation:

Because this is a 45 angle triangle we can assume the other side is also a 45 angle. Which means that CD=AD.

(6\sqrt 2)^2+(6\sqrt2)^2=144\\\sqrt 144=12

Tara and friends order a pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. Assuming that Tara has paid at least
lana [24]

Answer:The inequality is

x greater than or equal to(>/=) 14

Step-by-step explanation:

Let x represent the possible cost of the full pizza. Tara eats 3 of the 10 slices and pays $4.20 for her share. This means that the amount of pizza that Tara ate is 3/10×x = 3x/10

Assuming that Tara has paid at least her fair share, therefore

3x/10 = 4.20

3x = 4.20 ×10 = 42

x = 42/3 = 14

This means that the total cost of the pizza is at least $14. The inequality

how much the pizza could have cost becomes

x greater than or equal to(>/=) 14

I would multiply to get rid of the decimals and work with whole numbers.
Since we have numbers that are "hundredths", we would need to multiply every number by 100.
60d + 5e = -450
-12d + 30e = 276 Now that the decimals are gone, if we multiply the second equation by 5 the "d's" will cancel.
60d + 5e = -450
-60d + 150e = 1380
155e = 930
e = 6
Now plug 6 back in for e and solve for d.
60d + 5(6) = -450
60d + 30 = -450
60d = -480
d = -8
(-8, 6)
If you'd rather work it with decimals just let me know.
