Answer:
35
Step-by-step explanation:
70 × 0.5 = 35
or
50% = 1/2
so
70/2 = 35
Answer:

Step-by-step explanation:
By definition, two lines are perpendicular if and only if their slopes are negative reciprocals of each other:
, or equivalently,
.
Given our linear equation 3x + y = 3 (or y = -3x + 3):
We can find the equation of the line (with a y-intercept of 5) that is perpendicular to y = -3x + 3 by determining the negative reciprocal of its slope, -3, which is
.
To test whether this is correct, we can take first slope,
, and multiply it with the negative reciprocal slope
:


Therefore, we came up with the correct slope for the other line, which is
.
Finally, the y-intercept is given by (0, 5). Therefore, the equation of the line that is perpendicular to 3x + y = 3 is:

The easier way to multiply 2/15 by 3/20 will simply be by multiplying the numerators and denominators.
In order to multiply 2/15 x 3/20, we can simply multiply the numerator and the denominator. This will be
= 2/15 × 3/20
= 6/300
= 1/50
Also, in order to multiply the fractions, we can change them to decimal first. This will be:
= 2/15 × 3/20
= 0.133 × 0.15
= 0.01995
In conclusion, multiplying the numerators and denominators is easier and faster.

-4.4(s - 2) + 6.9s = 14.8
Distribute -4.4 into the parenthesis:
-4.4s + 8.8 + 6.9s = 14.8
Combine like terms:
2.5s + 8.8 = 14.8
Subtract 8.8 from both sides of the equation:
2.5s + 8.8 - 8.8 = 14.8 - 8.8
2.5s = 6
Divide both sides by 2.5:
2.5s/2.5 = 6/2,5
s = 2.4
s =
