Answer:
(-4,27)
Step-by-step explanation:
Let combine each equations
We know 4 is a root already so this means that our next root have to be
So set the quotient equal to zero.
Plug -4 into one of the equations.
To find the unit rate do 649.60/116=5.60
($5.60)kg
to find how much for 192 kilograms we have to multiply the unit rate we have to sub in the kg
5.60×192=1075.2
192kg= $1075.20
Area of the label is calculated as diameter*PI*height
So if height of tomato can is 3 times the can of tuna: hTOM=3*hTUNA
Diameter of a tomato can is three times smaller so: dTOM=dTUNA÷3
so Area of a tomato can label= A=(dTUNA÷3)*PI*3*hTUNA
A=dTUNA*PI*hTUNA
and the area of a tuna can label=
A=dTUNA*PI*hTUNA
So, the label areas are the same.
Answer:
Inequality: x + 4 ≥ 12
Solution: x ≥ 8
Step-by-step explanation:
<u>Plus</u>: "+" → to add something to something else
<u>Greater than or equal to</u>: "≥" → the expression on the left side of the inequality sign is greater than the expression on the right side of the sign.
Let x be the unknown number.
A number plus four is greater than or equal to twelve:
x + 4 ≥ 12
To solve the found inequality, subtract 4 from both sides:
⇒ x + 4 - 4 ≥ 12 - 4
⇒ x ≥ 8
Therefore, the solution to the inequality is x ≥ 8. The unknown number x can be any real number equal to or greater than 8.
Answer:
The length is 13
Step-by-step explanation:
w+w+l+l= perimeter
if the length is 3m less than twice the width then let's do some math.
42 divided 2 =21. so the width and length of one side have to equal 21. For example, let's use 8 as the width. The length would be twice(16) minus three(13) 13 plus 8 is 21. WOW it equals half of it so no we know the length is 13 and the wdith is 8.
