Which equation can best be modeled by the expression 10(-4)

Answer:

y = [tex]-\frac{1}{3}[/tex]

[tex]2\frac{2}{3}=x[/tex]

Step-by-step explanation:

To solve a system of equations, solve one or both of the equations for the same variable. Then multiply one of the equations such that the coefficients of one variable are the additive inverse of the variable in the other equation. After doing so, add the two equations, then solve for the other variable using inverse operations. Finally, substitute the value of the other variable into one of the original equations in the system and solve for the unknown variable.

2x + y = 3

y = x - 2

First, manipulate the first equation such that the equation is solved for (y), this can be done using inverse operations,

y = 3 - 2x

y = x - 2

Now multiply the second equation by (2) so that the (x) coefficients are additive inverses of each other,

y = 3 - 2x

2y = 2x - 4

Add the equations,

3y = -1

Inverse operations,

3y = -1

/3     /3

y = [tex]-\frac{1}{3}[/tex]

Now back solve, substitute the value of (y) into the equation and solve for (x),

[tex]y=x-3\\[/tex]

Substitute,

[tex](-\frac{1}{3})=x-3[/tex]

+3

[tex]2\frac{2}{3}=x[/tex]

Answer:

Pat is right

Step-by-step explanation:

first multiply/divide then add/subtract,

Beth: 20 - 15 = 45 => 5 ≠ 45

Pat: 20 - 15 = 5 => 5 = 5

Answer:

Pat

Step-by-step explanation:

There is only one correct answer. To find it, you must follow the correct order of operations.

There is a subtraction and a multiplication. There are no parentheses.

The rule is that you must do the multiplication before the subtraction.

20 - 5 * 3 =

= 20 - 15

= 5

In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.

The correct answer is 5, and Pat is correct.

Answer:

Gain = $666.67

Step-by-step explanation:

The businessman exchanged 660000 INR to US Dollar using the exchange rate of $1 = INR 110

Value of the money in dollars is;

(660000 × 1)/110 = $6000

Now, Nepali currency is reevaluated by 10%. This means it's value has gone up by 10%.

Thus, exchange rate of $1 is now;

110 - 10%(110) = INR 99

Thus, 660000 INR to US Dollar using this new exchange rate gives;

(660000 × 1)/99 = $6666.67

Therefore he made a gain.

Gain = 6666.67 - 6000

Gain = $666.67

Answer:

46°

Step-by-step explanation:

Given that :

Angle, A = 66°

Angle B = 68°

The sum of angles in a triangle is given by :

A + B + C = 180° (sum if angles una triangle)

66° + 68° + C = 180°

134° + C = 180°

C = 180° - 134°

C = 46°

Hence, angle C is 46°

Answer:

  x = 2√2 ≈ 2.83

Step-by-step explanation:

The side length of an isosceles right triangle is 1/√2 times the hypotenuse length. If x is the side length, then ...

  x = 4/√2 = 4(√2)/2

  x = 2√2 ≈ 2.83

Answer:

The measure of a snart is 2 and that of a snert is 8.

Step-by-step explanation:

Represent the size of a snert by e and that of a snart by a.

Then e - a = 6.  This assumes that e > a.

2e + a = 18.  Substitute e - 6 for a, obtaining:

2e + (e - 6) = 18.

Simplifying, we get

2e + e - 6 = 18, or

3e = 24, and so

e = 8

Remembering that e - a = 6, we have 8 - a = 6.  Then a must be 2.

The measure of a snart is 2 and that of a snert is 8.

the answer is C or it got to be D or B

Step-by-step explanation:

x^2 = 285.61

x = 16.9

4x = 67.6 cm

Answer: v+6*8*2 = 96

v = 6*8 = 48

5.5-2 = 3.5

48*3.5 = 168

168/2 = 84

96+84 = 180

The volume is 180 feet.
