Answer:(E). 25:2
Step-by-step explanation:
First ratio:
Us : India is 5 : 2
Second ratio
India : British is 5 : 1
multiply(5:2) by 5 and multiply (5:1) by 2 to balance the India stamps.
Therefore now
Us : India is 25 : 10
India : British is 10 : 2
The ratio of us : British is 25:2
#30 and #31 are in y = mx + b. m = slope, and b = y-intercept.
30. slope = 2/3 y-intercept = 1
31. Slope = -9/5 y-intercept = -4
To make the x's get on the right side of the equal sign, subtract it on both sides.
32. 6x - y = -2
32. 6x - y - 6x = -2 - 6x
32. y = 6x - 2
7 1/2 is 7.5 and 3/4 is .75, so 7.5 divided by .75 is 10.
Answer:
-0.7x⁹
Step-by-step explanation:
sqrt(0.49x¹⁸)
sqrt(0.49) × sqrt(x¹⁸)
0.7 × -x⁹
-0.7x⁹
Since x is negative, -x⁹ is positive
