Answer:
60
Step-by-step explanation:
f(t)+g(t)=(1^2+21)+(41-3)=1+21+38=22+38=60
When an equality is set up like this you are going to have 2 answers
Original inequality: <span>-3 ≤ 5 – 2v < 7
</span><span>When you solve this problem, solve it by making two equations
You will reuse 5-2v in both equation
-3 </span>≤ 5-2v
&
5-2v < 7
now do simple math
-3 ≤ 5-2v
-8 ≤ -2v
4 ≤ v
however when you divide when you divide by a negative number for an inquality you MUST change the sign to its opposite so
4 ≤ v will be 4≥ v
5-2v < 7
-2v < 2
v < -1
since we divide by a negative in order to get the variable by itself we change the sign to its opposite
v < -1 becomes v > -1
Answer:
The value of the unit rate is 8
Step-by-step explanation:
we know that
To calculate the unit rate simply divide the first number by the second number
so
![12:1\frac{1}{2}](https://tex.z-dn.net/?f=12%3A1%5Cfrac%7B1%7D%7B2%7D)
Convert mixed number to an improper fraction
![1\frac{1}{2}=1+\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}](https://tex.z-dn.net/?f=1%5Cfrac%7B1%7D%7B2%7D%3D1%2B%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B1%2A2%2B1%7D%7B2%7D%3D%5Cfrac%7B3%7D%7B2%7D)
substitute in the expression above
![12:\frac{3}{2}=\frac{24}{3}=8](https://tex.z-dn.net/?f=12%3A%5Cfrac%7B3%7D%7B2%7D%3D%5Cfrac%7B24%7D%7B3%7D%3D8)
