Answer: x = 13.4
Step-by-step explanation:
We translate 'English' to 'math':
'decreased by' is subtraction
'is' means '='
12(x - 10) = 2x + 14
12x - 120 = 2x + 14
subtract 2x from each side
10x - 120 = 14
Add 120 to each side
10x = 134
Divide by 10 , to isolate the 'x'
x = 13.4
If we substitute 13.4 for 'x' back in the first equation, we get 40.8 for each side, so the equation balances.
I hope this helps.
Answer:
67.2g of sugar will be needed to make 8 cake
Step-by-step explanation:
8.4g x 8 cake
= 67.2g sugars
(-4,-5)(2,13)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (13 - (-5) / (2 - (-4)
slope(m) = (13 + 5) / (2 + 4)
slope(m) = 18/6 = 3
y = mx + b
slope(m) = 3
(2,13)...x = 2 and y = 13
now we sub, we are looking for b, the y int
13 = 3(2) + b
13 = 6 + b
13 - 6 = b
7 = b
so ur equation is : y = 3x + 7
