Answer:
11%
Step-by-step explanation:
The equation would be 99=1200(r)(0.75). You would solve the equation to get the answer 11/100. Then you could convert it to a decimal to get 0.11, Then multiply the decimal by 100 to get 11.
Answer:Yes she has enough
Step-by-step explanation:
Total ounces=11
1st recipe=6 ounces
2nd recipe=1/4 ounces
1 pound =16 ounces
= 1/4 pounds × 16 ounces/1 pound
= 4 ounces
First recipe + Second recipe
= 6 ounces + 4 ounces
= 10 ounces.
10 ounces of walnuts and Marni has 11
Let 2x – y = 3 ——— equation 1
Let x + 5y = 14 ——— equation 2
Making x the subject in eqn 1, = x = y + 3 / 2 ——— eqn 3
• Put eqn 3 in eqn 2
(y + 3 / 2) + 5y = 14
6y = 14 – 3/2
6y = 25/2
y = 25/12
• put y = 25/12 in eqn 3
x = (25/12 + 3/2)
x = 43/12
