You can use the substitution method.
You substitute the first equation to the second equation to get the value of x.
x + 3y = -14
x + 3(2x) = -14
x + 6x = -14
7x = -14
x = -14/7 = -2
Substitute the value of x to the first equation.
y = 2(-2) = 4
Answer:
We just have to multiply not cross multiply,
10/18
Now, divide the equation
5/9 will be ur answer
<span>8.42 x 10^3
</span>Use PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
Solve exponent first
<span>8.42 x 10^3
</span>8.42 x 1000
Solve the rest
8.42 x 1000
8420
8420 is between
D.) 8400 and 8500
First, let's introduce a variable:
Let n represent the number we are trying to find.
20 % x n = 58
0.20 x n = 58
0.20n = 58
n = 290
Therefore, 58 is 20% of 290.

Answer:
C. 62.8 units
Step-by-step explanation:
Use distance formula or Pythagorean theorem.
Pythagorean-
6^2+8^2= radius^2
100= radius^2
10= radius
radius= r
Use circumference formula.
C=2pir
C=2pi10
C=62.83
