Answer:
x=
17
/9 or x=
25
/9
Step-by-step explanation:
9(3x - 7) ^2= 16
9(3x - 7) ^2-16= 0
as we know that (a-b)^2=a^2-2ab+b^2
9((3x)^2-2(3x)(7)+(7)^2=0
solving this we got the below equation
81x2−378x+425=0
By Factorizing the equation
(9x−17)(9x−25)=0
9x−17=0 or 9x−25=0
x=
17
/9 or x=
25
/9
11.) 4/5 * 3/4 = 12/20 reduces to 3/5
12.) 5 / (1/3) = 5 * 3 = 15
13.) 5 3/6 * 1 1/11 = 33/6 * 12/11 = 396/66 = 6
14.) 3 5/9 * 3/8 = 32/9 * 3/8 = 96/72 reduces to 4/3 or 1 1/3
15.) (2 5/6) / (1 1/2) = (17/6) / (3/2) = 17/6 * 2/3 = 34/18 reduces to 17/9 or
1 8/9.
16.) 24 / (2 3/4) = 24/(11/4) = 24 * 4/11 = 96/11 = 8 8/11
17.) 7 1/2 * 5 4/5...estimate : 8 * 6 = 48
18.) 9 8/15 * 11...estimate : 10 * 11 = 110
19.) (48 5/9) / (7 1/8)...estimate : 49/7 = 7
20.) (50 3/7) / (9 2/3)...estimate : 50/10 = 5
Answer:
Likely
Step-by-step explanation:
It is very likely that you will pick a blue marble because the bag is mostly filled with blue marbles so even if it is random it is more probable
Answer:
2:1
Step-by-step explanation:
12 divided by 6 = 2
6 divided by 6 = 1
2:1
Answer:
-1
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 3-7)/(2- -2)
= (3-7)/(2+2)
= -4/4
= -1
