Answer:

76

Step-by-step explanation:

multiply 19 and 4 to get 76. If you plug in 76 as x you can check to see if it's true

Answer:

a.The associative property allows us to change the grouping of terms that are added together.

b.When changing the grouping, the order of the terms stays the same; only the parentheses change position.

c.The expression a + (b + c) + d is an equivalent expression.

e.The expression (a+ b) + c + d is an equivalent expression.

Step-by-step explanation:

The correct statements are statement first, statement second, statement third, and statement fifth are correct.

It is defined as the combination of constants and variables with mathematical operators.

As we know,

The associative property allows us to change the grouping of terms that are added together.

= a + (b + c)

= (a + b) + c

The correct statements are:

Thus, the correct statements are statements first, second, third, and fifth are correct.

Both RSA and AST measure 27.1

Step-by-step explanation:

Since SA, "bisected" (split in half by equal parts) angle RST, the RSA and AST is equal

therefore 54.2 / 2 =27.1

Bisect- means the segment halved/split the angle into 2 equal parts

Answer:

Step-by-step explanation:

g(x) = x² + 2

To find g(3) , substitute the value of x that's 3 into g(x) , that is for every x in g (x) replace it with 3

That's

g(3) = 3² + 2

= 9 + 2

We have the final answer as

Step-by-step explanation:

When Steve woke up. His temperature was 102º F. Two hours later it

was 3º lower. What was his temperature then?

Answer:

We know that in a parallelogram two opposite angles are equal -

[tex] \\ \implies \sf \: 2x + 2y = 360 {}^{ \circ} \\ \\ \\ \implies \sf \: x + y = 180 {}^{ \circ} \qquad \quad \: (i) \\ [/tex]

Given -

[tex] \\ \implies \sf \: x = \frac{2}{3} y \\ \\ \\ \implies \sf \frac{x}{2} = \frac{y}{3} = k \\ \\ \\ \qquad \sf \small \underline{ x = 2k \: \: \& \: \: y = 3k} \\ [/tex]

Now, by using equation (1) :

[tex] \\ \implies \sf \: 2k + 3k = 180 \\ \\ \\ \implies \sf \: 5k = 180 \\ \\ \\ \implies \sf \: k = \frac{180}{5} \\ \\ \\ \large{ \boxed{ \sf{k = {36}^{ \circ} }}} \\ [/tex]

Now, by putting the value of k in x and y.

Therefore, the right option and smallest angle is b) 72°.

Answer:

[tex]\boxed{\tt A. \angle8 \ and \angle 7}[/tex]

Step-by-step explanation:

Supplementary angles are angles that add to 180 degrees.

Let's examine the answer choices.

A. ∠8 and ∠7

⇒ These angles are on a straight line together, so they are supplementary.

B. ∠5 and ∠1

⇒ These angles have no relation to each other. They are on different lines that are not parallel.

C. ∠7 and ∠4

⇒These angles also have no relation to each other.

D. ∠2 and ∠4

⇒ These angles are vertical, but not supplementary.

The correct answer is A. ∠8 and ∠7

Answer:

The situation of balloon B

Step-by-step explanation:

Balloon A is released 5 feet above the ground and our ground level be 0 feet. Let k be the rate at which it rises and t the time it takes to rise. Its height y, above the ground after time x is y = kt + 5

For Balloon B since it is released at ground level at which ground level is taken as 0 feet, let t be the time it takes to rise above the ground and k the rate at which it rises above the ground. Its height y above the ground after tie x is y = kt

Since the expression for Balloon B is y = kt and the expression for Balloon A is y = kt + 5, only the situation of Balloon B can be expressed in the form y = kx.

This is because the rate of rise of Balloon B follows a direct proportionality while the rate of rise of Balloon follow a joint proportionality since it starts from a point other than ground level.

Answer:

5/8

Step-by-step explanation:

You need to convert to a simplified fraction by placing the numbers to the right of the decimal over 1000. Then reduce the fraction.

Answer:

(12 + 3x)x

Step-by-step explanation:

(12 + 3)x = 12x + 3x = 15x

(12 + 3x)x = 12x + 3x²

15x

12x + 3x = 15x

They all equal 15x except for (12 + 3x)x

d= 10/7

Step-by-step explanation:

Basically what you do is 12/6 and 10/7 for d, because it is the greatest and least on both sides. You do the same for b so it would be 10-7=3 and 12-6=6

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (- 1, 6)

m = [tex]\frac{6-4}{-1-1}[/tex] = [tex]\frac{2}{-2}[/tex] = - 1
