Answer:
338=u/70
Step-by-step explanation:
To find the equation, simply write out what the problem states: the cost of 4 dinners plus the cost of 0.2 dinners (20%) is $24.00:
4pp + 0.2pp = 24
Simplify:
4.2pp = 24
Answer:
19.714
Step-by-step explanation:
Given :
Yearly Tuition Frequency
12-16 5
17-21 4
22-26 3
27-31 2
We calculate the midpoint (x) = (lower + upper) / 2
The mean yearly tuition :
The midpoint (x) :
X ___ F ___ Fx
14 __ 5
19 __ 4
24 __ 3
29 __ 2
The mean = Σfx / Σf
Σfx / Σf = (14*5 + 19*4 + 24*3 + 29*2) / (5+4+3+2)
Mean = 276 / 14
Mean yearly tuition = 19.714
Since the sum of the angles of a triangle is 180 degrees, we simply have to add all the angles and equate it to 180 to solve for x. So:
100 + 12x + 4 + 14x - 2 = 180
26x = 78
x = 3
So, x is equal to 3.
Let's solve your equation step-by-step.
3−6(x−7)=42−6x
Step 1: Simplify both sides of the equation.
3−6(x−7)=42−6x
3+(−6)(x)+(−6)(−7)=42+−6x(Distribute)
3+−6x+42=42+−6x
(−6x)+(3+42)=−6x+42(Combine Like Terms)
−6x+45=−6x+42
−6x+45=−6x+42
Step 2: Add 6x to both sides.
−6x+45+6x=−6x+42+6x
45=42
Step 3: Subtract 45 from both sides.
45−45=42−45
0=−3
Therefore, this is No Solutions.
