You solve this by plugging one equation into the other. Usually you have to rewrite one equation to make this work. In this case I choose to rewrite y-4x=0 as y=4x.
After plugging it into the second, you get:
3x + 6*4x = 9 => 27x = 9 => x=1/3
Putting this solution back into y=4x gives us y=4/3
Answer:
65 hundreds= 65 x100 = 6500
290 ones= 290 x1= 290
The sum of both = 6500 +290= 6790
Answer:
x = 30
F = 130
G = 50
Step-by-step explanation:
f and g are supplementary which means they add to 180
5x-20 + 3x - 40 = 180
Combine like terms
8x - 60 = 180
Add 60 to each side
8x-60+60 = 180+60
8x = 240
Divide by 8
8x/8 = 240/8
x = 30
F = 5x -20 = 5*30 -20 = 150 -20 = 130
G = 3x-40 = 3*30 -40 = 90-40 = 50
Answer: 1,296 candles
Step-by-step explanation:
48 cartons have been packed yet only 30 have been loaded. The cartons still left are;
= 48 - 30
= 18 cartons
Each carton holds 72 candles so the candles that have not yet been loaded are:
= 18 * 72
= 1,296 candles
B and A.
6 times as many free throws so 6(free throws) and same for rate of jump shots
Next is difference, which means subtraction of 3(number) and 2(number)
So 3x-2x
