Answer:
x=100
Step-by-step explanation:
(2x+8)+(71-x)=180
2x+8+71-x=180
x+80=180
x=180-80
x=100
Answer:
1/5
Step-by-step explanation:
5 = 1/5
6= 1/6
1/6= 6/1 (or just 6)
5/6= 6/5
Do you see the pattern?
Every number has a reciprocal except for 0. There is nothing you can multiply by 0 to create a product of 1, so it has no reciprocal.
Answer:
this is question is wrong it you typed it wrong
how come the triangle named XYZ and the angle wxz and if there 2 triangles one must be a failure because there is no triangle which all his angels equals more than 180°
look again and if possible take a picture of the question
You would need 2 & 1/2 because if for 3 you need 1 & 1/2 ( which is half) then for 5 you would divide it by 2 and get 2 & 1/2
Answer:
x=120cc volume of 7% solution
Step-by-step explanation:
Saline solution(7% solution) +
Saline solution (19% solution) = Saline solution (11% solution)
Saline solution(7% solution): (0.07)(x)
x= unknown volume
Saline solution (19% solution): (0.19)(60)
60= given volume
Saline solution (11% solution)= (0.07)(x+60)
x+60= Total volume
solve for x
(0.07)(x) + (0.19)(60) = (0.11)(x+60)
0.07x +11.4 = 0.11x + 6.6
0.11x - 0.07x = 11.4 - 6.6
0.04x = 4.8
x = 4.8/0.04
x = 120 cc volume of 7% solution
