Answer:
x = 4
Step-by-step explanation:
Equation: 3x + 13 = 25
Step 1: Subtract 13 from both sides.
3x + 13 = 25
<u>- 13 - 13</u>
3x = 12
Step 2: Divide both sides by 3.
<u>3x</u> = <u>12</u>
3 = 3
x = 4

Answer:
In words, if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent. If in triangles ABC and DEF, angle A = angle D = right angle, AB = DE (leg), and BC = EF (hypotenuse), then triangle ABC is congruent to triangle DEF.
Answer:
45
Step-by-step explanation:
x - 7 = 38
add 7 to both sides to get the variable by itself
x = 45
Lets expand both multiplications first.
Simplify down the right side.
Add 38.25 to both sides.
Subtract 11.22x from both sides.
Divide by -21.42 on both sides. Because we're dividing by a negative, we need to change the inequality direction.
This means, out of the options available, (-2.5, ∞) is the correct answer.
