X+y=3
Subtract x from both sides
y=-x+3
Substitute
2x--x+3=6
2x+x+3=6
3x+3=6
Subtract 3 from both sides
3x=3
Divide both sides by 3
x=1
If the ratio of the dimensions is 4:7 and the shorter dimension is 10ft, we know that the 10ft corresponds to the 4 in this scenario. We can set up the equation as follows:
You have to multiply by 2.5 to get from 4 to 10. And since we want to make sure we are maintaining the ratio, we have to multiply the denominator, 7, by 2.5 as well.
This means your shorter side has a length of 10ft and your longer side has a length of 17.5ft.
AREA
The formula for the area of a rectangle is: 
So we can plug our dimensions into the formula: 
So 175 is our area. But we can't forget about units! Since this is area and we multiplied our units together, our units would be squared. That means our answer is <u>175 square feet</u>.
PERIMETER
The formula for the perimeter of a rectangle is: 
We can plug our dimensions into the formula: 
So 55 is our perimeter. Of course, we can't forget about our units. Because this is perimeter, we only added our units together, so they don't change. That means our answer is <u>55 feet</u>.
Assuming the x stands for multiplication... follow the ordering rules:
First let's take care of the exponents. 4²=16 and (-6)²=36. At the same time I will add some spacing between the terms:
3x16 - 36 + 4 - 6x4
Now do the multiplications:
48 - 36 + 4 - 24
The rest is just addition and subtraction
48 - 36 + 4 - 24 = -8
Answer:
The question is incomplete, here is the complete question.
Year Real GDP per Capita
1985 6,000
1986 6,300
1987 6,700
1988 7,200
1989 7,850
1990 8,250
1991 8,450
1992 8,550
1993 8,575
1994 8,510
1995 8,370
1996 8,100
1997 7,950
1998 7,925
1999 7,960
2000 8,035
2001 8,155
The information above describes the real GDP per capita for a country for the period from 1985 through to 2001. If a new business cycle began in 1985, how long was this cycle? In which year did the peak occur? The trough occurred in which year? How long was the expansion? How long was the recession?
Step-by-step explanation:
a.If a new business cycle began in 1985, how long was this cycle?
The business cycle describes the rise and fall in production output of goods and services in an economy. In the data given above, a business cycle is complete in the year 1998. If the cycle started in 1985 then it was 14 years long.
b. In which year did the peak occur? The trough occurred in which year?
In the data given above, the peak occured in year 1993 (GDP per capita of 8,575) and trough occurred in the year 1998 (GDP per capita of 7,925).
c. How long was the expansion? How long was the recession?
Expansion was 9 years long (1985-1993) and recession was of 5 years (1994-1998).
