R = 6x + 5y
x = 7, R = 18
Substitute them in: 18 = 6(7) + 5y
18 = 42 + 5y
-24 = 5y
y = -24/5
It’s already in its simplest form
If you meant 3 1/10, 3 1/10 as an Improper Fraction is 11/10.
If you meant 31/10, 31/10 is already a Improper Fraction.
Answer: 2,940
Step-by-step explanation: 245 x 12= 2,940
To solve this problem, all we have to remember is that
fractions also mean division. Therefore this means that:
4 / 7 = 4 divided by 7
We can use either a calculator to solve for this or do the
long division method of division (your choice). Now to solve this simply, I
used the calculator and got the answer:
4 / 7 = 0.571428571
However, the problem asked us to round this to the nearest
thousandth. We know that the decimal places are:
0.(tenths)(hundredths)(thousandths)
So we are to round this into 3 decimal numbers which gives
us:
<span>4 / 7 = 0.571</span>
Answer:
2.09 sq. units
Step-by-step explanation:
We can simply use the formula for area of a sector of a circle.
Area of sector =
Where is the angle and r is the radius.
<em>It is given that the angle is 15 and radius is 4. We plug them in and find the area:</em>
<em></em>
<em />
<em>Thus area of sector is 2.09 sq. units.</em>
