Answer:
0.03A + 0.03B = 800
A + B = 20000
Step-by-step explanation:
Let one part A of the total money invested with 3% interest = $A
Therefore, other part B of the money invested with 5% interest = $B
Interest = Principal amount × Rate of interest × Duration of investment
If the duration is 1 year,
Interest = Principal amount × Rate of interest
Return on part A = A × 0.03
Return on part B = B × 0.05
Total return = $800
So the equations will be,
0.03A + 0.03B = 800 -------(1)
Since, total money invested = $20000
Equation will be,
A + B = 20000 -------(2)

A cyclist rode 4.5 miles in 0.4 hours. How fast was the cyclist going in miles per hour
Answer:
1)Distance covered by cyclist=3.75 miles.
Time =0.3 hours.
Speed= Distance ÷Time
Speed =3.75÷0.3=12.5 miles per hour.
2) Speed = 12.5 miles per hour, Distance = 4.5 miles .
Time = Distance ÷Speed.
Time = 4.5÷12.5=0.36 hours.
Time taken to cover 4.5 miles is 0.36 hours.
is 11.25 mph

Write an equation for a line that is parallel to y = -3x – 5 that goes through the point (-1, 8)
Answer:
y = -3x +5
Step-by-step explanation:
Parallel means that both slopes are the same.
This gives us y = -3x + C so far.
To find the y-intercept, we need to get x to 0.
Since we know the point (-1, 8), we can plug the number in into our equation
y = -3x + C.
8 = -3(-1) + C
8 = 3 + C
8 - 3 = C
5 = C or C = 5.
Now plug in C into our unsolved equation to get y = -3x +5.
2x+2y=16
Standard to slope intercept form.
The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
The equation 2x + 2y = 16 in slope-intercept form is
y = -x + 8.
Where slope = -1 and y-intercept is 8
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
We have the equation as,
2x + 2y = 16
We need to convert in the form of y = mx + c.
Subtract 2x on both sides.
2y = -2x + 16
Divide both sides by 2.
y = (-2x + 16) / 2
y = -x + 8
This is in the form of slope-intercept form.
Where slope = -1 and y-intercept is 8
Thus,
The equation 2x + 2y = 16 in slope-intercept form is
y = -x + 8.
Where slope = -1 and y-intercept is 8

Solve for f
-f + 2+ 4f = 8 - 3f
Answer:
f = 1
Step-by-step explanation:
-f + 2 + 4f = 8 - 3f
First, I'll add like terms.
2 + 3f = 8 - 3f
Then, I'll add 3f on both sides.
2 + 6f = 8
Next, I'll subtract 2 on both sides.
6f = 6
Finally, I'll divide 6 on both sides.
f = 1
Therefore, f = 1.

19/36 - ⅜ =???????????????????????????
Answer:
1936−3/8=11/72
Step-by-step explanation:
19/36−38=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(19/36, 3/8) = 72
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(19/36×22)−(38×99)=?
Complete the multiplication and the equation becomes
38/72−27/72=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
38−27/72=117/2
This fraction cannot be reduced.
Therefore:
1936−38=11/72
(Some of the numbers might be a fraction)
