Activity 4: APPROXIMATE ME! (PERFORMANCE TASK) Approximate the quantities asked in each number using the following things or part of your body as unit of measurement. Write your answers on the space allotted for each number. (1 pt each for no. 1 to 4, 2 pts each for no. 5 to 7)

1. How many hands fit the width of your notebook?

2. How many feet (standard unit of measurement) is the width of your main door?

3. How many dangkal can fit into your Mathematics 7 Learning Activity Sheet's length?

4. How many yards is your blanket on its width?

5. How many inches can fit in an 8 dangkal plant?

6. How many inches can fit in 10 yards (standard unit of measurement) of rope?

7. How many dangkal can fit into 3 yards of cloth?

please answer this

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
