There are 5 times as many males as females on the maths course at university. What fraction of the course are male? Give your an
Oksi-84 [34.3K]

Answer:

5/6

Step-by-step explanation:

Let 'x' be number of females in the course

Number of males= 5x

total number of students= 5x+x

                                         = 6x

Fraction of male students= number of male students/total number of students

                                         = 5x/6x

                                         = 5/6

Write an equation in slope-intercept form for the line that satisfies the following condition.passes through (20, 1), parallel t
Dmitrij [34]

Slope-intercept form:  y = mx + b  

(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)

For lines to be parallel, they have to have the same slope.

y = 6x + 6    The slope of this line is 6, so the parallel line's slope is also 6.

Now that you know m = 6, substitute/plug it into the equation:

y = mx + b         Plug in 6 for "m" in the equation  

y = 6x + b     To find "b", plug in the point (20, 1) into the equation

1 = 6(20) + b

1 = 120 + b       Subtract 120 on both sides to get "b" by itself

1 - 120 = 120 - 120 + b

-119 = b         Now that you know b = -119, plug it into the equation

y = 6x - 119

(7t-2)-(-3t+1)=-3(1-3t)
Aleksandr-060686 [28]
First you need to multiple minus in second bracket, also in other side you need to multiple - 3 in bracket

7t - 2 + 3t - 1 =  - 3 + 9t \\  \\ 10t - 3 =  - 3 + 9t \\ 10t - 9t =  - 3 + 3 \\ t = 0
Final answer is 0
