If there is a 506,211 pound whale on a scale and you add another whale of 424,809 pounds on the scale how much would they both weigh?
Answer:
r = 5
Step-by-step explanation:
12 - 1/5r = 2r + 1
12 - 0.2r = 2r + 1
12 - 0.2r + 0.2r = 2r + 0.2r + 1
12 = 2.2r + 1
12 - 1 = 2.2r + 1 - 1
2.2r = 11
2.2r ÷ 2.2 = 11 ÷ 2.2
r = 5
I have an answer for you
YELLOW y = -1/3x + 5
BLUE y = undefined
GREEN y = -2
BLACK y = 2x - 6
RED y = 2x + 5
Hope this helps!
Answer
(x - 4)
Step by step explanation
To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.
Here (x - 4) is a factor.
Therefore, x = 4
when we plug in x = 4 in the given expression, we get zero.
Let's check it out.
3(4)^3 + 8 (4)^2 - 87(4) + 28
192 + 128 - 348 + 28
348 - 348
0
The answer is (x - 4)
Thank you.
The total pages in the book are 510.
Step-by-step explanation:
Lets say, the total pages are x
Mo read the book with following proportion.
Monday: 2/5.x
Pages left: 1.x - 2/5.x = 3/5.x
Tuesday: 1/2.x of 3/5.x = (1/2.x) . (3/5.x) = 3/10.x
Pages left: 3/5.x - 3/10.x = 3/10.x
Wednesday: 5/9.x of 3/10.x = (5/9.x) . (3/10.x) = 1/6.x
Thursday : ?
Lets say the total proportion is 1. The proportion of book read on Thursday can be calculated as:
1.x - 2/5.x - 3/10.x - 1/6.x = 2/15.x
Also given, Mo read 68 more pages on Tuesday than Wednesday.
Therefore,
3/10.x - 1/6.x = 68
2/15x = 68
x = 510
Therefore, the total pages in the book are 510.
