Answer:

  • 3 and 5/3

Step-by-step explanation:

<u>Solving in steps:</u>

  • |3x-7| + 7 = 9
  • |3x-7|  = 2

<u>1. If 3x - 7 > 0</u>

  • 3x - 7 = 2
  • 3x = 9
  • x = 3

<u>2.  If 3x - 7 < 0</u>

  • 3x - 7 = -2
  • 3x = 5
  • x = 5/3

He science club has 4 members. The club bought b bumper stickers to split among its members. Write an expression that shows how
Nataliya [291]

Answer:

b / 4

Step-by-step explanation:

If you are splitting <em>b</em> bumper stickers between <u>4</u> members, you must divide the number of bumper stickers by the number of members, which is 4! Dividing is just like if you were to divvy something up between people, but it is a mathematical term! This will give you  b / 4.

Find the missing values of the variables. The diagram is not to scale. (Image attached below)thank you ! :)
aniked [119]

Answer:

\begin{gathered} x=\text{ 99}\degree \\ y\text{ = 64}\degree \end{gathered}

Explanation:

Here, we want to get the value of x and y

From the given image, the angle y and 116 lie on a straight line

The sum of the angles on a straight line is 180 degrees

Thus:

\begin{gathered} 116\text{ + y = 180} \\ y\text{ =180-116} \\ y\text{ = 64}\degree \end{gathered}

The sum of the internal angles of a polygon can be calculated by the formula:

180(n-2)

where n is the number of sides the polygon has

In the case of the given question, n is 4

Substituting the value of n, we have it that:

180(4-2)\text{ = 360 degrees}

To get the value of x:

\begin{gathered} x\text{ + y + 125 + 72 = 360} \\ But\text{ from above , y = 64}\degree \\ Substituting\text{ this:} \\ x\text{ + 64 + 125 + 72 = 360} \\ x\text{ = 360-125-64-72} \\ x\text{ = 99 } \end{gathered}

Three farmers shared an order for fertiliser between them in the ratio 3:4:7.
Viktor [21]

Answer:

45 kg = Bethan's share

105 kg = Jade's share

Step-by-step explanation:

Let 3x = Bethan's share

4x = Noah's share

7x = Jade's share

Since Noah's share was 60, then 4x = 60

                                                          x = 15

3(15) = 45 kg = Bethan's share

7(15) = 105 kg = Jade's share

Write the equation of the line that passes through the given points (0,-3) and (-15,-5)
son4ous [18]

Answer:

y=2/15x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-5-(-3))/(-15-0)

m=(-5+3)/-15

m=-2/-15

m=2/15

y-y1=m(x-x1)

y-(-3)=2/15(x-0)

y+3=2/15(x)

y+3=2/15x

y=2/15x-3
