Social Studies rate, S = 30/ 1.5 = 20pages/hr
Novel rate, N = 150/2 = 75pages/hr
Novel rate as a % of Social Studies rate...
N/S × 100% = 75/20 × 100% = 375%
Answer:
They are proportional
Step-by-step explanation:
Cross multiply, if the results are the same, they are proportional. If not, well then they're not proportional.
25 × 27 = 675
45 × 15 = 675
They have the same result
They are proportional
Answer:
97,99,101,103
Step-by-step explanation:
Let x = first odd integer
x+2 = 2nd odd integer
x+4 = 3rd odd integer
x+6 = 4th odd integer
Sum of 4 odd integers is 400
x+ (x+2) + (x+4)+(x+6) = 400
Combine like terms
4x +12 = 400
Subtract 12 from each side
4x+12-12 = 400-12
4x = 388
Divide by 4 on each side
4x/4 = 388/4
x=97
The first integer is 97
The 2nd is 97+2 =99
The third ix 97+4 = 101
The 4th is 97+6 = 103
Answer:
x=5 and x=-11
Step-by-step explanation:
(x-2)(x+8)=39
Subtract 39 from both sides
Factor:
(x-5)(x+11)=0
Set factors to 0.
x-5 =0
x+11 =0
x=5, x=-11
