Answer:

$733.33

Step-by-step explanation:

The question is on finding the principal value

Formulae for simple interest

S.I= P×R/100×T where P is the invested amount of money, R is interest rate and T is time in years

Given that;

Simple interest=$77 , R=7% and T=1.5 years then

S.I= P×R/100×T...................substituting the values given

77=P×7/100 × 1.5

77=P×0.105

77/0.105 =P

$733.33=P

2(7x-9)=5(x+3)<br> Solve for x

Nadya [2.5K]

Answer:

x = 3.67

Step-by-step explanation:

Simplify both expressions

14x - 18 = 5x + 15

Subtract the bigger (n)x by the smaller

14x - 5x = 9x

Plus the smallest by itself, giving you:

9x - 18 = 15

+18 +18

9x = 33

Simplify ( divided by 3 )

3x = 11

x = 3.67

What is the equation of the circle with center (0, 0) that passes through the point (5, -4)?

Katyanochek1 [597]

The standard form of a circle is $(x-h) ^{2} +(y-k) ^{2} = r^{2}$ where h and k are the center and x and y are the coordinates you're given. We need to solve for the radius to finish this off correctly. Filling in, we have $(5-0) ^{2} +(-4-0) ^{2} = r^{2}$ and $25+16= r^{2}$ , giving us that $r^{2}=41$ . Therefore, our equation is $x^{2} + y^{2} =41$
