Answer:
3×(27-7) says to subtract 7 from 27 first, then multiply with 3; but 3×27-7 says to multiply 3 by 27 first ,then subtract 7.
The second bullet is the correct option
Yes and rational numbers are numbers that can be written as a ratio of two integers
Answer: 8x
2.9543127e+21xy
9x
Step-by-step explanation:
4x^2=16x 28x=28x 36=36 16x+28x-36 16+28=44-36=8x
125x^6= 30517578125x 27y^15= 2.9543127e+21 30517578125x-2.9543127e+21= 2.9543127e+21xy
4-7=3+x=3x 5-8=3+x=3x 3x * 3x= 9x
x = sqrt{y}k
K is the constant of proportionality.
128 = sqrt{16}k
128 = 4k
128/4 = k
32 = k
x = sqrt{y}k
x = sqrt{36}•32
x = 6 • 32
x = 192
Find y when x = 48.
x = sqrt{y}k
48 = sqrt{y}32
48/32 = sqrt{y}
(48/32)^2 = [sqrt{y}]^2
2.25 = y
Answer:
y=14.5
Step-by-step explanation:
A slope of 3/2 means that for every unit it moves to the right, it will move 1.5 units up. The x of 4 is 7 more than the -3 of our other point. 7*1.5=12.5, and 12.5+2=14.5.
