(0, 0) (3, −2) (−2, 3) (−3, 0)

Answers

(3, -2) satisfies both equations. 3-2=1, and -3-2=-5.

(-2,3) wouldn't work with the second equation (2+3=5 not -5) so it's out. (0,0) is obviously out 0+0=0 same with (-3,0) -3+0=-3. The only one left is (3,-2) 3-2=1 and -3-2=-5. Since it's the only one to fit it's the correct option :)

Is 0.06 bigger than 0.054

Answers

To compare decimals, start by looking at the whole numbers (the number to the left of the decimal). Since the number for both is zero, next move to the other side of the decimal, the tenths place. Both numbers are still zero, so now move to the next place over, the hundredths place. We have a 6 in the hundredths place for one of the numbers and a five in the hundredths place for the other one... We can stop right there... 6 is greater than 5 so the number with the 6 in the hundredths place is the larger number.

0.06 > 0.054

Tes because the 6 in the hundreths plsce is greater than the 5 in the hundreths plsce

Anita can paint the shed in 5 h. If Kris helps her, they can paint the shed in 3 h. How long will it take Kris to paint the shed alone?

Answers

Anita can paint the shed in 5 hours. If Kris helps her, they can paint the shed in 3 hours. How long would it take Kris to paint the shed alone?
----
Anita rate = 1/5 job/hr
Together rate = 1/3 job/hr
Kris rate = 1/x job/hr
Equation:
rate + rate = together rate

1/x + 1/5 = 1/3
----
Multiply thru by 15x to get:
15 + 3x = 5x
2x = 15
x = 7.5 hrs (time for Kris to do the job alone)

I WILL MAKE YOU BRAINLIEST!!!!Triangle STU is formed by the three squares D, E, and F:

Which statement best explains the relationship between the sides of triangle STU?

ST + TU = SU, because 36 + 64 = 100

(ST)2 + (TU)2 = (SU)2, because 102 + 62 = 82

ST + TU = SU, because 102 + 62 = 82

(ST)2 + (TU)2 = (SU)2, because 36 + 64 = 100
