C

Step-by-step explanation:

These triangles are congruent under the SAS congruence criterion. We can prove it using the following steps :

Given :

In triangle 1 and 2 :

Since the SAS congruence criterion says that two triangles are congruent if two of their sides and one included angle is equal and since these 2 triangles fulfill all of those rules, we can conclude that these triangles are congruent under the SAS congruence criterion.

Answer:

= 105(x+2)/33-x

Step-by-step explanation:

Given the expression

[3(x+2)*10*7]÷70 - 2(x+2)

= 3(x+2)*70÷70 - 2(x+2)

= 210(x+2)/70-2x-4

= 210(x+2)/66-2x

= 210(x+2)/2(33-x)

= 105(x+2)/33-x

Answer:

Your answer is 37

Step-by-step explanation:

Caanan is 62 miles away and since he drives at 50 miles per hour, and if it is 2:30 then 30 minutes is half a hour, which means you divide 50 in half by 2 and get 25. After you do that then you subtract 62 and 25 to get your answer 37. Have a good day!!! :)

−26xy+9x+9y

Step-by-step explanation:

Let's simplify step-by-step.

(−9x)(y)+9x−17xy+9y

=−9xy+9x+−17xy+9y

Combine Like Terms:

=−9xy+9x+−17xy+9y

=(−9xy+−17xy)+(9x)+(9y)

=−26xy+9x+9y

Answer:

Step-by-step explanation:

Slope intercept form of a line is

y=mx+b, where m=slope and b=y intercept

m=(y2-y1)/(x2-x1) I chose points (0,3) and (4,4) from graph so

m=(4-3)/(4-0)=1/4 so now the line is

y=x/4+b, using point (4,4) we can solve for b

4=4/4+b

4=1+b

b=3 so the line is

y=x/4+3 or more neatly

y=(x+12)/4

When you multiply or divide both sides of an inequality by a negative, you must switch the direction of the inequality sign. Please give this idea of your full attention. Even the most advanced algebra students will sometimes forget to switch the direction of the inequality sign when multiplying or dividing both sides of an inequality by a negative.

Answer:

26

Step-by-step explanation:

2 squares + 3 circles = 31. So, the sum of the squares is divisible by two, and the sum of the circles is divisible by 3. Then, I used trial and error to figure out that the square's value is five, and the circle's value is seven. 5 + 7 + 7 = 19. 27 - 19 = 8. The triangle's value is eight. 5 + 7 + 12 = 24. It works. 15 + 7 + 4 = 26

The sum of the shapes in the fourth row is 24 and this can be determined by using the arithmetic operations and by forming the linear equations.

Given :

In the diagram, each shape has a value and the sums of the shapes in each of the first three rows is given.

Let the symbol of the circle be denoted by 'x', square be denoted by 'y', and triangle be denoted by 'z'.

Now, the linear equations that represent the given diagrams are:

2y + 3x = 31   --- (1)

y + 2x + 3z = 27   --- (2)

3y + x + z = 24    --- (3)

Now, evaluate equation (1) for 'y'.

[tex]\rm y=\dfrac{31-3x}{2}[/tex]  --- (4)

Now, substitute the value of y in equation (2).

[tex]\rm \dfrac{31-3x}{2}+2x+3z=27[/tex]

31 - 3x + 4x + 6z = 54

6z = 23 - x

[tex]\rm z = \dfrac{23-x}{6}[/tex]    --- (5)

Now, substitute the value of 'y' and 'z' in equation (3).

[tex]3\times \dfrac{31-3x}{2}+x+\dfrac{23-x}{6}=24[/tex]

[tex]279-27x+6x+23-x=144[/tex]

158 = 22x

[tex]x = \dfrac{79}{11}[/tex]

Now, substitute the value of x in equations (4) and (5).

[tex]\rm z = \dfrac{23-\dfrac{79}{11}}{6}[/tex]

[tex]z = \dfrac{29}{11}[/tex]

[tex]\rm y=\dfrac{31-3\times \dfrac{79}{11}}{2}[/tex]

[tex]y=\dfrac{52}{11}[/tex]

The last equation is written in terms of x, y, and z as:

= 3y + x + w

Now, substitute the value of known terms in the above equation.

[tex]=3\times \dfrac{52}{11}+\dfrac{79}{11}+\dfrac{29}{11}[/tex]

[tex]=\dfrac{156+79+29}{11}[/tex]

= 24
