80% of the students in Lea’s class earned an A or a B on the weekly math test. If 20 students got an A or a B, how many students

are in Lea’s class?
Will give Brainliest!!

P.S. This is 6th Grade math on Edge 2020
Here are the options:
0 20 is 80% of what number?
0 20 × 4 = 80, so 100 × 4 = 400 students
0 20 + 60 = 80, so 100 + 60 = 160 students
0 80 ÷ 4 = 20, so 100 ÷ 4 = 25 students
0 80 – 60 = 20, so 100 – 60 = 40 students

A. 20 is 80 of what number
blondinia [14]3 years ago
5 0

Answer:

25

Step-by-step explanation:

80% got A orB  out of 100% so

20 students are 80% of the class

we need 20% to find all 100% so

80%/4=20% and 20/4=5 students represent 20%

100%= 80%+20% =20students+5students=25 students

Find the equation of the line that passes through the following points. Write the equation in slope-intercept form.
ra1l [238]

Answer:

The equation in the slope-intercept form will be:

y  = 1/4x - 7

Step-by-step explanation:

Given the points

  • (-4.-8)
  • (-8, -9)

\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-4,\:-8\right),\:\left(x_2,\:y_2\right)=\left(-8,\:-9\right)

m=\frac{-9-\left(-8\right)}{-8-\left(-4\right)}

m=\frac{1}{4}

We know that the slope-intercept of line equation is

y=mx+b

where m is the slope and b is the y-intercept

substituting m = 1/4 and the point (-4, -8) to find the y-intercept 'b'

y = mx+b

-8 = 1/4(-4)+b

-8 = -1 + b

b = -8+1

b = -7

so the y-intercept = b = -7

substituting m = 1/4 and b = -7 in the slope-intercept form of line equation

y = mx+b

y  = 1/4x + (-7)

y  = 1/4x - 7

Thus, the the equation in slope-intercept form will be:

y  = 1/4x - 7
