Answer:
9
Step-by-step explanation:
2,3,4,7,7,7,9,9,14,17,21
21,17,14,9,9,7,7,7,4,3,2
3,7,7,7,9,9,17,21
Answer:
6/9 = 2/3
Step-by-step explanation:
1/3 = 3/9
3/9 = 3/9
3/9 + 3/9= 6/9 = 2/3
3.9 and 5.3, when rounded off and mult. together, produce the product 20.
Thus, the decimal point must follow the first two digits of your answer, whether estimate or "exact."
3.9*5.3 = 20.67 by calculator.
Answer:
m=-1
Step-by-step explanation:
2.3-5m=9.8+2.5m
+5m=9.8+5m
2.3=9.8+7.5m
-9.8 -9.8
-7.5=7.5m
/7.5 /7.5
-1=m
Hello,
x,y,z∈ IN





==>
x∈{35,36,37}
y∈{47,48,49}
z∈{141,144,147}
We must go futher:
if x=35 then y=4*35/3=46.666 not good , not whole
if x=36 then y=4*36/3=48 ok
if x=37 then y=37*4/3=49.333.. not good
So there is only one solution (36,48,144) for (x,y,z)
No problem with z for z=3/1*4/3*x=4x ==>whole.
