The complete question in the attached figure
we know that
if <span>the weights are perfectly balanced
40*(x)=50*(11-x)
40x=550-50x------------> 50x+40x=550--------------> x=6.11
x=6.1 ft
the answer is 6.1 ft</span>
Answer:
13/20 (i'm guessing that what you meant) is 1.65 as a decimal
Step-by-step explanation:
A useful way to conceptualize converting mixed numbers to a decimal is to consider the mixed number as two separate components: the whole number component and the fractional component. In this case, we have -1 as the whole number and 13/20 as the fractional component.
- 6n - 3 + 7 = 5
- 6n + 4 = 5
- 6n = 1
n = - 1/6
Answer:
11.5 feet
Step-by-step explanation:
We can set the porportions of pole height/shadow length equal
13/6.5=23/x
We can cross multiply, 13x=149.5 and divide to get x=11.5
Or we could have seen that the shadow is half the height of the pole.
Answer:
Width: 4
Length: 9
Step-by-step explanation:
P = 2( l + w)
26 = 2(2x + 1 + x)
26 = 2(3x + 1)
26 = 6x + 2
6x = 24
x = 4
l = 2x + 1
2(4) + 1 = 9
