Answer:
3.428 or 3 wholes 3/7
Step-by-step explanation:
6 : 7 = n : 4 : 2
6 : 7 = n : 4
6/7 = n/4
7n = 24
n = 24 /7
n = 3. 428 or 3 wholes 3/7
Answer:
7 x 2, 14, the area, then use pie, 3.14 to get the circle
Step-by-step explanation:
Answer:
x= 12 and y= 2
Step-by-step explanation:
First you would line up the equations so the x's and y's are on top of each other. Then you would multiply x+y=14 by 3 to give you 3x+3y=42. After that you subtract 2x-3y=30 and 3x+3y=42 to give you an answer of x=12. After that, you plug in x with 12 in the equation x+y=14. You subtract 12 from both sides to get an answer of 2. So ur solution is (12,2)
Step-by-step explanation:
By binomial theorem,
T(r+1) = nCr * a^(r+1) * b^r
Term 4 = 7C3 * (2x)^4 * (-5y)^3 = 35 * (16x^4) * (-125y^3) = -70000x^4y^3.
