ABCD is a parallelogram. Find the measure of angle ABC.​
iVinArrow [24]

Answer:

∠ABC = 50°

Step-by-step explanation:

Therefore, ∠D ≅ ∠B

∠D = 38° + 12°

∠B = 38° + 12°

∠B = 50°

∠ABC = 50°

How many jelly beans are in a 2-liter jar? HELP ME PLEASE
Galina-37 [17]

1. The number of sample size 1 jelly beans in a 2-liter jar is <u>645</u>.

2. The number of sample size 2 jelly beans in a 2-liter jar is <u>640</u>.

3. The number of sample size 3 jelly beans in a 2-liter jar is <u>637</u>.

<h3>What is a mathematical operation?</h3>

A mathematical operation is an expression involving the use of mathematical operands and operators to compute values.

Mathematical operations use variables, numbers, and operators (addition, subtraction, division, and multiplication).

<h3>Data and Calculations:</h3>

Total weight = 1,150g

Weight of the jar = 440g

The total weight of the jelly beans = 710g (1,150 - 440)

Sample Size 1: the number of jelly beans = 645 (710/22.0 x 20)

Sample Size 2: the number of jelly beans = 640 (710/22.2 x 20)

Sample Size 3: the number of jelly beans = 637 (710/22.3 x 20)

Thus, the number of jelly beans in a 2-liter jar depends on the sample size of the jelly beans.

Correct answer gets Brainliest! Solve for x.
Simora [160]

Subtract 13 from both sides:

-7-13 \geq -5x

-20 \geq -5x

Divide both sides by -5. Since this is a negative number, you have to invert the inequality sign:

4 \leq x

Which means

x \geq 4
