<span>2 + 13x, because (19x − 6x) + 2 = 13x + 2 = 2 + 13x</span>

Answer: The correct option is

(C) $2+13x$ because $(19x-6x)+2=13x+2.$

Step-by-step explanation: We are given to select the expression that is equivalent to $19x-6x+2$ with reason.

To find the equivalent expression, we need to simplify the expression.

The simplification is as follows :

$19x-6x+2=(19-6)x+2=13x+2=2+13x.$

Thus, the equivalent expression is $2+13x$ because $(19x-6x)+2=13x+2.$

Option (C) is CORRECT.

3(m + 5 + 9m)

A.
(1) 3m + 15 + 27m
(2) 3(10m + 5)

B. 3(m + 5 + 9m)....distributive property
(3 * m) + (3 * 5) + (3 * 9m) =
3m + 15 + 27m

C. 3(m + 5 + 9m) = 3(10m + 5)......m = 1
3(1 + 5 + 9(1) = 3(10(1) + 5)
3(1 + 5 + 9) = 3(10 + 5)
3(15) = 3(15)
45 = 45

Helpppppppppppp plss with this problem

3241004551 [841]

Given :7872 ÷ 305.

Because it's estimation. So, we need to estimate the number 7872 to 8000.

In order to divide 8000 by a number we need to estimate 305 to the 400. Because 400 is exact divisor of 8000.

If we divide 8000 by 400 we get 20.

And it's obviously less then 60000 ÷ 300= = 200.

20 < 200.

<h3>Therefore, Harrison is absolutely correct.</h3>

Find the value of x. Round your answer to the nearest tenth.

Crazy boy [7]

<h2>The value of x "option A) 12.5" is required answer.</h2>

Step-by-step explanation:

In given figure,

Base (b) = 11 and Angle = 28°

To find, the value of x = ?

We know that,

$\cos A=\dfrac{b}{h}$

Where, h is the hypotaneous = x

⇒ $\cos 28=\dfrac{11}{x}$

⇒ $x=\dfrac{11}{\cos 28}$

The value of $\cos 28$ = 0.8829

⇒ x = $\dfrac{11}{0.8829}$

⇒ x = 12.458

⇒ x ≈ 12.5

∴ The value of x ≈ 12.5

Thus, the value of x "option A) 12.5" is required answer.

The Thompson family is buying a car that can travel 70 miles on two gallons of gas. Assume that the distance traveled in miles y

artcher [175]

70/2 = 35

The car gets 35 miles per gallons.

You can also find that out by looking at the slope of the equation. y = 35x. 35 is the slope here.

For your graph, plot the points:
(0,0)
(1,35)
(2,70)
(3,105)
(4,140)
(5,175)
(6,210)
(7,245)
(8,280)

And then draw a line through the points.

Please help me ill put the question up for a lot of point, and i will mark as brainliest!!!

sattari [20]

Step-by-step explanation:

(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)

1/(8x⁵y^-7) = y⁷/(8x⁵)

4x^-9y⁴ = 4y⁴/x⁹

so, the whole expression is then

y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹

4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)

so, D is the correct answer.
