96 grams of zinc. If the ratio is 4:11 and the 11 correlates to 264 than 4x:11x could be rewritten as 4x:264. 264/11= 24 and 24*4=96
P-1=5p+3p-8
p-1=8p-8
-1=7p-8
7=7p
p=1
hope this helps :)
Find two numbers that multiply to be 20 and add up to be -12. The question
5 x 4 = 20
2 x 10 = 20
20 + -32 = -12
good luck!!!
Answer:
0.2 and 0.8
Step-by-step explanation:
Draw a diagram to illustrate the problem as shown below.
Let v = speed of the westbound car, mph
Because the eastbound car travels 4 mph faster than the westbound car, its speed is (v+4) mph.
After 2 hours,
the westbound car travels 2v miles west, and the eastbound car travels 2(v+4) miles east.
Because they become separated by 208 miles, therefore
2v + 2(v+4) = 208
4v + 8 = 208
4v = 200
v = 50 mph
The westbound car travels at 50 mph.
The eastbound car travels at v+4 = 54 mph
Answer: The eastbound car travels at 54 mph.
