Answer: 10
use (PEMDAS)
P parentheses ()
E exponents
M multiplication • , () , x
D division
A addition +
S subtraction -
Explanation:
There are no parentheses.
There are exponents.
The multiplication is the exponents.
There is division.
There is addition and subtraction.
-how to solve-
First, do 2 to the second power and get 4.
Next, do 12-2+4 divided by 8.
Next do multiplication: there’s no more.
Next do division: you can’t do 4 divided by 8 so instead, do 12-2 = 10 plus 8.
Hope this helps!
Answer:
80 runners
Step-by-step explanation:
24/30=0.8
0.8*100=80
Answer:
m<a = 77
m<b= 103
Step-by-step explanation:
m<a+m<b = 180(supplementary angles)
3x/8+50+x+31=180
3x/8+x+81=180
(3x+8x)/8=180-81
3x+8x=99*8
11x=792
x=792/11
x=72
now
m<a=3x/8+50
=(3*72)/8+50
=77
m<b=x+31
=72+31
=103
F(x) = -2x +1 ( slope = -2 y intecept is 1)
replace x with 0 and solve for y =-2(0)+1 = 1 ( 0,1)
replace x with 2 and solve for y: -2(2) +1 = -4+1 = -3 (2,-3)
plot those 2 coordinates and draw a line
this is the red line on the attached graph
do the same for the g(x) formula

Answer:
z = 83/(6-c-t)
Step-by-step explanation:
-cz +6z = tz +83
Subtract tz from each side
-cz +6z -tz = 83
Factor out z
z(6-c-t) = 83
Divide by (6-c-t)
z(6-c-t) /(6-c-t) = 83/(6-c-t)
z = 83/(6-c-t)
