Answer:

Step-by-step explanation:

we know that 1 percent of 30 is just 30 / 10 which is 3. Is 6 a multiple of 3? yes it is. 6 / 3 = 2. that means 6 is 20 percent of 30 but it hasn't been decreased by 6, it is 6. meaning that the answer is 100 - 20 which is 80

Answer:

The pair of triangles that are congruent by the ASA criterion isΔ ABC and Δ XYZ.

The pair of triangles that are congruent by the SAS criterion is Δ BAC and ΔRQP.

Step-by-step explanation:

Two triangles are congruent by ASA property if any two angles and their included side are equal in both triangles .In triangles Δ ABC and Δ XYZ the equal side 5 is between the two equal angles. So these triangles are congruent by ASA criterion.

Two triangles are congruent by SAS if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle .In triangles Δ BAC and ΔRQP. the included angles A and Q are equal and hence the triangles are congruent by SAS criterion.

Can you help me solve and describe the steps used to find x for the equation 2(x + 4) – 10 = 12

Anettt [7]

Hi there!

To solve, let's rewrite this equation.

$2 (x + 4) - 10 = 12$

Step 1) Simplify both sides of the equation.

$(2) (x) + (2) (4) + - 10 = 12 2x + 8 + - 10 = 12$ (Distribute)

$(2x) + (8 + - 10) = 12$ (Combine Like Terms)

$2x + - 2 = 12 2x - 2 = 12$

Step 2) Add 2 to both sides.

$2x - 2 + 2 = 12 + 2 2x = 14$

Step 3) Divide both sides by 2.

$\frac{2x}{2} = \frac{14}{2}$

$x = 7$

Final Answer -

$x = 7$

Hope this helps!

Message me if you need anything else, I'd be happy to help you! :D

A toy rocket is launched from a platform 42 feet above the ground at a speed of 91 feet per second. The height of the rocket in

True [87]

Lets get started!

height = -16t² + 91t + 42
After 3 sec means, t = 3, so we substitute t with 3

H = -16(3)² + 91(3) + 42
= -144 + 273 + 42
= 171 feet
