Answer:
b
Step-by-step explanation:
Given
12x+ 8 = 10x + 18 ( subtract 10x from both sides )
2x + 8 = 18 ( subtract 8 from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
The equation has one solution
The temperature rose 22 degrees
Answer:
7.5
Step-by-step explanation:
So the constant proportionality is easy, it is the depindent veriable (how much it cost) divided by the independent veriable (how much fabric you have).
Put simply you know how much it will cost if you know how many yards you have. so if i have 2 yards i know it cost 15 dolars.
We could make a simple algebraic expretion that describes the proportionality.
C⁒y=7.5
So 7.5 is our constant, so if you know the cost or how many yards we have we always know what the other is.
So if i had 6.7 yards how much would it cost.
It would cost $50.25, what i did was i multiplied 6.7*7.5(our constant) and we got out cost c. Just to dubble check we can plug it in;
50.25⁒6.7 does=7.5 so it works.
0.06 or you can just put 6.
Basically, you have to multiply 30% x 20.
Glad I could help☺️
If the function is asking what if x = 5, then we will substitute the exponent x with 5.
From the formula above, we will multiply 3 to itself five times (3 x 3 x 3 x 3 x 3) = 243
After that, we will multiple 243 to 1/9 or simply divide 243 by 9.
Therefore, the value of the function if x = 5 is 27. Option A is the answer.
