Answer:
(D) Divide the first equation, , by 2.
Step-by-step explanation:
Given:
We need to find the operation performed on equation so as to get resultant equation as:
From Above we can see that there is no change in equation 2 with respect to resultant equation.
Also Resultant equation is simplified form of equation 1.
Simplifying equation 1 we get;
We can see that 2 is the common multiple on both side.
Hence we will divide equation 1 with 2 we get
which is the resultant equation.
Hence (D) Divide the first equation, , by 2 is the correct option.
Answer:
4 ounces
Step-by-step explanation:
To solve this problem, lets first take into account that 1 cup is equal to 8 ounces. Now, we need to cross multiply. Lets input the values 1, 8, and 0.5 (0.5 is 2/4) as shown below:
Next we cross multiply. We multiply 1 and x, and we multiply 8 and 0.5.
Now, if we simply put the variable x and the number 4 into an equation, we get:
4 ounces is the answer.
Answer:
20%, or 4 questions
Step-by-step explanation:
16 / 20 or 8 / 10 = 80%
What's left over?
100 - 80 = 20
20%
Answer: the number must be placed in the box is 9
suppose: the number must be placed in the box is x
have:
5u + 3(4u - 6) = -3u -27 + 20u + x
⇔ 5u + 12u - 18 = -3u - 27 + 20u +x
⇔ 17u + 3u - 20u = -27 + 18 + x
⇔ 0 = x - 9
⇔ x = 9
