You can substitute the value of y(5/6 x + 1) from the first equation for y in the second and get
which becomes
and you get
60 + 90
GCF = 30
(30 * 2) + (30 * 3) = 30(2 + 3) <== the correct way
The mistake Axial made was he did not pick the greatest common factor...he picked 3 instead of 30.
Answer:
a = −bx+7x−4 over x
Step-by-step explanation:
solve for a:
7+ax−5x=3+2x−bx
add 5x to both sides:
ax−5x+7+5x=−bx+2x+3+5x
ax+7=−bx+7x+3
add -7 to both sides:
ax+7+−7=−bx+7x+3+−7
−bx+7x−4
lastly divide both sides by x.
Cookies = 24
drinks = 8
Apply ratios
Cookies / drinks = 24/8 = 3
drinks /cookies = 8/24 = 1/3
5.
There are 3 times as many cookies as drinks
There are 1/3 times as many drinks as cookies
6.
drinks = 8
pizzas = 2
Drinks/pizzas = 8/2 = 4
Pizzas / drinks = 2/8 = 1/4
There are 4 times as many drinks as pizzas.
There are 1/4 times as many pizzas as drinks.
7.
Cookies = 24
pizzas = 2
Cookies /pizzas = 24/2 = 12
Pizzas / cookies = 2/24 = 1/12
There are 12 times as many cookies as pizzas.
There are 1/12 times as many pizzas as cookies.
The expression can be simplified by subtracting the terms.
2-3=-1
The final answer is -1.
