5)

Equilateral triangle, all sides are equal

So 2x + 5 = 11

2x = 6

x = 3

Answer is the first one

3; Equilateral theorem

6)

Isosceles triangle has at least two congruent sides.

So 6x = 24

x = 4

Answer x = 4

Converse of the Base Angle Theorem

7)

5x + 7 = 52

5x = 45

x = 9

Answer

x = 9

Base angle theorem

8)

5y - 14 = 3y

2y = 14

y = 7

The data below represents the number of minutes Jake and Sarah spent doing chores

hichkok12 [17]

-

The median number of minutes for Jake and Sarah are equal, but the mean numbers are different.

-

For this, you never said the choices, but I’ve done this before, so I’m going to use the answer choices I had, and hopefully they are right.

Our choices are -

• The median number of minutes for Jake is higher than the median number of minutes for Sarah.

• The mean number of minutes for Sarah is higher than the mean number of minutes for Jake.

• The mean number of minutes for Jake and Sarah are equal, but the median number of minutes are different.

• The median number of minutes for Jake and Sarah are equal, but the mean number of minutes are different.

————————

So to answer the question, we neee to find the median and mean for each data set, so -

Jack = [90 median] [89.6 mean]
Sarah = [90 median] [89.5 mean]

We can clearly see the median for both is 90, so we can eliminate all the choices that say they are unequal.

We can also see that Jack has a higher mean (89.6) compared to Sarah (89.5).

We can eliminate all the choices that don’t imply that too.

That leaves us with -

• The median number of minutes for Jake and Sarah are equal, but the mean number of minutes are different.

Find the x- and y-intercepts of the graph of 10x+2y=20 State each answer as an integer or an improper fraction in simplest form.

Deffense [45]

Answer:

Slope: $\frac{10.000}{2.000} = -5.000$
x - intercept: $\frac{10}{5} = 2$ .
y intercept: $\frac{10}{1} = 10.00000$ .

Step-by-step explanation:

<u>Simplify:</u>

Simplify the equation by subtracting what is to the right of the equal sign from both sides of the equation:
10*x+2*y-(20)=0.

<u>Step 1:</u>

Pull out like factors:
10x + 2y - 20 = 2 * (5x + y - 10)

<u>Step 2:</u>

Equations which are never true:
Solve:
2 = 0
This can't be solved.
A non-zero constant never equals 0.
Equation of a straight line:
Solve: 5x+y-10 = 0
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula:

y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 5x+y-10 = 0 and calculate its properties
Calculate the y-intercept:
Notice that when x = 0 the value of y is 10/1 so this line "cuts" the y axis at y=10.00000
y-intercept = 10/1 = 10.00000

Calculate the x-intercept:

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 10.000 and for x=2.000, the value of y is -0.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -0.000 - 10.000 = -10.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -10.000/2.000 = -5.000

<u>Answers:</u>

Slope = -10.000/2.000 = -5.000
x-intercept = 10/5 = 2
y-intercept = 10/1 = 10.00000

the measure of ∠D is 5 times the measure of ∠E the two angles are supplemanty find the measure of each angle

hammer [34]

Because the angles are supplementary, they add to 180 degrees.

I solved this by dividing $\frac{180}{6}$ which gives me 30 degrees.

multiply 30 by 5 gives you 150.

and 30 + 150 = 180
