Answer:
3. 10 X 20 = 200
6. 12 X 2 = 24
Step-by-step explanation:
TO FIND AREA OF A RECTANGLE YOU MULTIPLY LENGTH TIMES WIDTH
A = L X W
Answer:
small: 6.25
large: 18.25
Step-by-step explanation:
Set the large boxes as x and the small boxes as y (The weight is the constant).
3x+5y=86
6x+2y=122
Now just solve the systems of equations using either substitution or elimination.
-6x-10y=-172 multiply the whole equation by -2 to eliminate
6x+2y=122, add the equations
-8y=-50
y= 6.25
Plug in y either equation:
3x+5(6.25)=86
3x=86-31.25
3x=54.75
x=18.25
Each small box weighs 6.25 kilograms, each large box weighs 18.25 kilograms, to check plug in the values to the other equation to see if they add up correctly.
So your variable are these
x= # of accountants
x+10= # of supervisors
4(x+10)= # of mechanics
So you get the equation x+ (x+10) + (4x+40) = 230
and you solve for x
6x + 50 = 230
6x = 180
x=30
so accountants = 30
supervisors = 40
Mecahnics = 160
Answer:8:7
Step-by-step explanation:
16:14 divided by 2 = 8:7
Answer:
x> -1/8
Step-by-step explanation:
1/4 + x > 1/8
subtract 1/4 from each side
1/4 -1/4 +x > 1/8 -1/4
x > 1/8 -1/4
get a common denominator,8
x> 1/8 - 1/4 *2/2
x> 1/8 -2/8
x> -1/8
