The sencond is wrong but the first is good

Step-by-step explanation:

Answer:

The first step is to find a number that when subtracted from 2 gives you 2.

Step-by-step explanation:

The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so

first x-2=2, then x-2(+2)=2(+2)  which would give us,

x=4

*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.

Answer:

$57.8

Step-by-step explanation:

Answer:

$55.8

Step-by-step explanation:

68 times %15 = 10.2 so subtract 68 by 10.2 and that = 55.8

Answer:

Corresponding parts of coungruent triangles are congruent

Step-by-step explanation:

when you have two triangles and you have proved they are congruent, then each part of one triangle (side, or angle) is congruent to the corresponding part in the other.

Answer:

For shape 1, the angle would be 360/8 = 45 degrees

For shape 2, as it doesn't have rotational symmetry, it would just be 360 degrees.

Hope this helps.

The fraction that is equivalent to 4/7 among the given set of fractions is 8/14

From the question, we are to determine the fraction that is equivalent to 4/7

To determine this, we will reduce each of the given fractions to their lowest terms where possible

Dividing both the numerator and denominator by 3, we get

2/3

∴ 6/9 is not equivalent to 4/7

Dividing both the numerator and the denominator by 2, we get

4/7

∴ 8/14 is equivalent to 4/7

This is the lowest form of this fraction and it is not equivalent to 4/7

This is the lowest form of this fraction and it is not equivalent to 4/7

Hence, the fraction that is equivalent to 4/7 among the given set of fractions is 8/14.

D. rectangle

Step-by-step explanation:

The slopes of 2 lines are perpendicular when they are the negative reciprocal of each other. In this case, that is true, because 3 is the negative reciprocal of -1/3 and vice versa. This means it's either a rectangle or a square.

The lengths of the lines are not all the same, meaning it cannot be a square.

Therefore, the best name for the quadrilateral MATH is rectangle.
