Answer:

156

Step-by-step explanation:

3 ml of compound A used for every 4 ml of compound B in total it's 7 ml

To calculate how many ml of A used in a 364 ml drug we can divide 364 by 7

364 ÷ 7 = 52 which means there are 52, 7 ml in the 364

since 7 ml drug contains 3 ml conpound A there is

52 × 3 = 156 of compound A in the 364 ml drug

Hello,                                                                                                                       To solve this problem, you need to use a process of trial and error, and add up each number until you get 24 or above.  If you get above, it is wrong.  The only number that goes into 24 evenly is 8, so the answer is 8 keychains.<span>

For each equation given below, write ONE related equation. a) x + 5 = 18 b) 66x =330
GenaCL600 [577]

Answer:

x = 13 ; x = 5

Step-by-step explanation:

The easiest related equation to get is simply solving for x:

a) x + 5 = 18

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides:

x + 5 (-5) = 18 (-5)

x = 18 - 5

x = 13*

b) 66x = 330

Isolate the variable, x. Divide 66 from both sides of the equation:

(66x)/66 = (330)/66

x = 330/66

x = 5*

*Note: An equation simply is a expression that has an equal sign. This means that as long as there is an equal sign, it counts as an equation.
