The rule to use: when dividing fractions, invert and multiply.
-6 ÷ -(3/4) equals -6 * -(4/3) which equals 24 / 3 which equals
8
Answer:
x=6
Step-by-step explanation:
2(x-1)=x+4 multiply 2 to x and -1
2x-2=x+4 put your variables and numbers on the same sides by + or -
x=6 there's your answer! :)
Answer:
this is what i found hope it helps
Multiply to remove the variable from the denominator.
x = − 3/40y
Answer: year 1948
Step-by-step explanation:
1900 is our t = 0
The population of Greenville can be written as:
G = 4000 + 100*t
the equation for Springfield can be written as:
S = 1000*(1.04)^t
we want to find the value of t that makes S(t) = G(t)
4000 + 100*t = 1000*(1.04)^t
(4000 + 100*t) = 1.04^t
4 + 0.1*t = 1.04^t
now, you can graph both of this equations (left side and right side) and see in wich value of t the graphs intersect eachother, or you also may use different values of t until the values are about the same for both sides, which is the thing i did with the equation:
4 = 1.04^t - 0.1*t
You will find that the correct value is t = 48
So we can assume that in year 1948 the populations will be about the same.
Our current equation is:
-5(3n + 4) = 40
To solve for this, we need to use the Distributive Property. The Distributive Property allows any number/variable outside of the parenthesis to be multiplied by all numbers/variables inside of the parenthesis.
For example, 3(2 + 3) would be:
3(2) + 3(3)
6 + 9
15.
Now that we've defined our terms and provided an example, I think we're ready to solve.
-5(3n + 4) = 40
-5(3n) + -5(4) (multiplying a positive by a negative makes a negative)
-15n -20 = 40
Add 20 to both sides to get -15n by itself.
-20 + 20 = 0
40 + 20 = 60
We now have:
-15n = 60
Divide both sides by -15 to solve for n.
-15n / -15 = n
60 / -15 = -4
N = -4.
Your answer is A.) -4.
I hope this helps!
