Answer:
x= 2.5I didn't have equipment to do graph bt I think u will understand
Step 1) Set up a proportion
180 girls / x boys = 4 girls / 3 boys
540 = 4x
x = 135 boys
Step 2) Add the number of boys and girls together
180 + 135 = 315
Answer: 315 total students
Answer:
true because OR is 90°.and and also PR is 90°.
Answer:
y = x-1
Step-by-step explanation:
First step is to find the slope
Take two points on the line (1,0) and (2,1)
m = (y2-y1)/(x2-x1)
= (1-0)/(2-1)
= 1/1
The slope is 1
The y intercept ( where it crosses the y axis is -1)
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = 1x-1
y = x-1
Remember
(x^m)(x^n)=x^(m+n)
and
if a^m=a^n, where a=a then n=m
(x^4)(x^n)=x^5
(x^4)(x^n)=x^(4+n)
x^(4+n)=x^5
therefor
4+n=5
minus 4
n=1
