Answer:

2x+1

Step-by-step explanation:

that's a hard question

we know that g(x)= x-3

so f(g(x))= f(x-3)

we put it in the equation :

f(x-3)= 2(x-3) +7 = 2x-6+7 = 2x +1

Write sentences to explain 1/5 x 1/2 = 1/10

Andreas93 [3]

Answer:

Explaination down below

Step-by-step explanation:

Before you start this question, make sure you know this rule. When multiplying fractions, Multiply the numerator by the other numerator and multiply the denominator by the other one.

$\frac{1}{5}$ x $\frac{1}{2}$ . 1*1=1, so one is the numerator. 2*5= 10 so 10 is the denominator.

The final answer is $\frac{1}{10}$ .

You could also look at it another way. What is one half of one-fifth?

That is another way to look at it.

Classify each pair of numbered angles. Drag and drop the descriptions into the boxes to correctly classify each pair of numbered

Leona [35]

(i) Pairs of neighboring angles are supplementary and opposite angles have the same measure.

(ii) The two angles formed by a line coming out of another line are supplementary.

<h3>How to analyze pairs of angles</h3>

(i) When two straight lines pass through each other, then two pairs of opposite angles are constructed. A pair with angles of $(3\cdot x + 52)^{\circ}$ and another pair with angles of $(2\cdot x + 2)^{\circ}$ , each pair of angles with different measures are supplementary. $\blacksquare$

(ii) When a straight line comes out of another straight line, from a point distinct to any endpoint of the former, then we construct two supplementary angles. The largest angle has a value of $(10\cdot x + 20)^{\circ}$ , whereas the smaller one has a value of $(6\cdot x + 8)^{\circ}$ . $\blacksquare$

The composite figure is made up of two congruent rectangular pyramids joined at their bases. What is the total volume of the com

Sedaia [141]

The volume of a rectangular pyramid is
V = (1/3) A*h
where
A = the area of the rectangular base
h = the height

The two pyramids are congruent in volume.
The volume of one pyramid is
(1/3)*(2*7.5)*(6) = 11
The volume of the composite figure is 2*11 = 22

Answer: 22
