Answer:

The last one

Step-by-step explanation:

We need to keep the variable on one side of the inequality

y-5 is greater than or equal to -4

+5 +5

y is greater than or equal to 1

So the last one is correct

Step-by-step explanation:

∠A + ∠B + ∠C = 180°

Here the value of ∠B and C is given below...we need to find the value of ∠A ....

a + 120° + 40° = 180°

a + 160° = 180°

a = 160° - 180°

a = 20°

Transform the equation to isolate x: ax = bx + 1. How is

shepuryov [24]

Answer:

$x=\frac{1}{a-b}$

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.

Step-by-step explanation:

The given expression is $ax-bx+1$

We factor the left hand side to get:

$(a-b)x=1$

We divide both sides by: a-b

$x=\frac{1}{a-b}$

Observe that the difference of a and b is in the denominator.

The whole is of the form: $x\propto \frac{1}{a-b}$

The value of x is inversely proportional to the difference of <em>a</em> and <em>b</em>.

Solve 3x + 23 + x = 7. x = −4 x = 4 x = −0.25 x = 0.25

Maksim231197 [3]

<h2>______________________________</h2><h2>Solve for x | Solution and Explanation </h2>

______________________________________________

Hello! So...

We are given the following:

Solve for x.

$3x+23+x=7$

====================

1. Group the like terms.

$3x+x+23=7$

====================

2. Add similar elements ( $3x+x=4x$ ).

$4x+23=7$

====================

3. Subtract 23 from both sides.

$4x + 23 - 23 = 7 - 23$

====================

4. Simplify.

$4x=-16$

====================

5. Divide both sides by 4.

$\frac{4x}{4} =\frac{-16}{4}$

====================

6. Simplify.

$x=-4$ (aka. Option A)

====================

Hope this helps!

Which values of a and b make the following equation true? a = 11, b = 7 a = 11, b = 10 a = 28, b = 7 a = 28, b = 10

xz_007 [3.2K]

Answer:

The answer is

Step-by-step explanation:

$( {5x}^{7} {y}^{2} )( { - 4x}^{4} {y}^{5} ) = - 20 {x}^{a} {y}^{b}$

Multiply the terms on the left side of the equation

That's

$- 20 {x}^{11} {y}^{7} = - 20 {x}^{a} {y}^{b}$

Since the bases are the same we can equate the exponents

That's

${x}^{11} = {x}^{a}$

a = 11

And

${y}^{7} = {y}^{b}$

b = 11

Therefore

a = 11 and b = 7

Hope this helps you
