Building a is 180 feet shorter than building

2 answers:

8 0

Here is the set up:

a = b - 180
a + b = 1520

We have a systems of linear equations in two variables.

b - 180 + b = 1520

2b = 1520 + 180

2b = 1700

b = 1700/2

b = 850

Plug b = 850 into either equation.

I will use a + b = 1520.

a + 850 = 1520

a = 1520 - 850

a = 670

Answer:

Building a is 670 feet. Building b is 850 feet.

B= 850 ft
a= 670 ft

b + (b-80) =1,520
2b=1700
b=850 a=670 =(1,520-850)
850-670=180 ( difference between a and b)

Raja drove from A to B at an average speed of 50mph

natali 33 [55]

Answer:

44.7

Step-by-step explanation:

Speed = distance / time

speed from distance a to b = 50 = 10 / time

time = 10/50 = 12 minutes

Speed from a to c = 62 = distance / 30 minutes

distance = 62 x 0.5 = 31 m

diatance from b to c = 31 - 10 = 21

time = 30 - 12 = 28 minutes

speed = 21 / 28 minutes

31 / 0.47

How do you solve, 5 ^3x-4/25=625

gtnhenbr [62]

Step-by-step explanation:

(5^3x*25-4)/25=625

125^3x-4=625*25

5^x-4=15625

5^x=15625-4

5^x=15621 I can't solved by me if there is only 15625 then the answer will be 6 because 5^6=15625 but there is -4 too

In the 2017 fiscal year, the state of Alaska received $8.2 billion In revenues and had $7.2 billion in expenditures. What percen

konstantin123 [22]

To figure this out you can do 7.2/8.2, because you are trying to figure out how much of the total was used, and percentages would not be more than 100%. Doing this you would get ~.878. To convert this to a percent, you would just multiply it by 100, which would give you 87.8%. The question states to round to the nearest whole percent, leaving you with 88%. This means that 88% of the revenue was spent.

Hope that helped, don't be shy to comment on this if you have any questions about my explanation :)
