Answer:
b
Step-by-step explanation:
If Joe collected 94 stamps which are in April May and June, we could make an equation like this: A + M + J = All stamps
Plug in the values:
Isolate J:
Combine like terms:
He collected 33 stamps in June.
Consider the suggested option:
1) if in 20 gr. of 50% solution given, then pure salt in this mix is 0.5*20=10 gr., and pure water is 0.5*20=10 gr.
2) after Maya added 5 gr. pure salt is 10+5=15 gr. Total mass of mix is 15(pure salt)+10(pure water)=25 gr.
3) new solution is 15/25=0.6 or 60%.
Answer: 25 gr. of 60% salt solution.
If you round 3,826.301 and 175.6 to the nearest hundred you will get 3,800 and 200.
Multiply 3,800 * 200 = 760000
760,000 rounded to the nearest hundred thousand is 800,000.
The best estimate for the product 3,826.301 × 175.6 is B. 800,000.
Answer should be 20
4x5=20
