Q2
Bronze to aluminum is 25:2
The alloy is bronze plus aluminum, so by adding 25 + 2 you get 27.
Bronze to total is 25:27

25 is 27 as x is to 55

25/27 = x/55

27x = 25 * 55

x = 50.926

Answer: 50.926 kg of bronze

Find the semi monthly salary when the weekly salary is $1,200
cestrela7 [59]

Semi-monthly means twice every month, typically either on the 1st and 15th,
or on the 15th and last.

Months don't line up with weeks in any regular way.   Depending on the
company, if they say "bi-monthly", they may pay 24 times a year, or else
26 times a year.

If they pay every 2 weeks, the semi-monthly is $2400.

Jacob has $200 to spend on STAR WARS toys. He already purchased $75 on vehicles and new action figures will cost him $8 each. Ho
just olya [345]

Answer:

15 action figures

Step-by-step explanation:

Jacob had $200 to start off with. He spent $75 on vehicles, so we are going to subtract $75 from $200

200 - 75 = 125

He had $125 left. From the money he has left, he wants to purchase more toys. Action figures are $8 each. We will need to find how many action figures he can buy with the rest of his money. To do that, we will divide $125 by $8

125/8 = 15.625

He can buy 15 action figures with his remaining money. He will have remaining change.

I think the equation is:

8x + 125 = 200

8 gets the variable, 200 is the total, and 125 will not get the variable.
