Answer:
x = 72
Step-by-step explanation:
Make the problem simpler by eliminating the fractional coefficients:
x-9= 1/4x + (1/4x + 12) + (1/4x - 3), when multiplied by 4, becomes:
4x - 36 = x + x + 48 + x - 12
Summing up all the x terms, we get:
4x - 2x - x = 48 - 12 + 36
Then x = 72
Answer:
X=102 y=288 =390
Step-by-step explanation:
X=50+32=82=180-82=102
Y= 50+32=82=360-82=288
Total answer is =390
(1,-1) and (3,5)
Find slope first
y=mx+b
slope is also m
b is y-intercept
slope = y2-y1/x2-x1
x1=1
x2=3
y1=-1
y2=5
5-(-1)/(3)-(1)
6/2=3
y=3x+b
use (1,-1) into y=3x+b ( using substitution method)
-1=3(1)+b
-1=3+b
Move 3 to the other side
Sign changes from +3 to -3
-1-3+3-3+b
b=-4
Answer: C.) Y = 3x-4
Answer:
Bob drove from home to work at 75 mph. After work the traffic was heavier, and he drove home at 40 mph. His driving time to and from work was 1 hour and 9 minutes. How far does he live from his job?
=================
Avg speed for the round trip = 2*75*40/(75+40) = 6000/115 = 1200/23 mi/hr
RT distance = 1200/23 * 69 minutes * 1 hr/60 mins =
= 60 miles
30 miles each way

Answer:
Volume of rectangular prism = 
Step-by-step explanation:
Given rectangular prism is made up of small cubes of volume 1 cubic centimeter.
To find volume of rectangular prism.
Solution:
Volume of rectangular prism is = 
We know that all sides of a cube are equal in measure.
So, we will count the number of cubes on each side to get the exact measure.
Length side = 4 cubes = 5 cm
Width side = 2 cubes = 2 cm
Height side = 2 cubes = 2 cm
Thus volume of rectangular prism = 
Volume of rectangular prism =
