Here the first one, One goal in solving an equation is to have only variables on one side of the equal sign and numbers on the other side of the equal sign. The other goal is to have the number in front of the variable equal to one. The strategy for getting the variable by itself with a coefficient of 1 involves using opposite

What is a flat plane postulate?

Karolina [17]

Three noncollinear points are contained in one and only one plane -- flat plane postulate. If two points are in a plane, then the line containing the points is in the same plane -- plane intersection postulate.

Saul made some extra money last year from a part-time job. He invested part of the money at 2% with four times as much invested

omeli [17]

Answer:

$4000

Step-by-step explanation:

Given that :

Total interest earned = $150

Let amount invested (p) at 2% = x

Amount invested (p) at 3.25% = 4x

Interest = principal * rate * time

At 2%:

(x * 0.02 * 1 ) + (4x * 0.0325 * 1) = 150

0.02x + 0.13x = 150

0.15x = 150

x = 150 / 0.15

x = 1000

Hence,

Amount invested at 2% = x = 1000

Amount invested at 3.25% = 4x = 4(1000) = 4000

Brrunno [24]

Answer:

m∠ABC = m∠BED; Corresponding Angles Theorem

Step-by-step explanation:

<u>Given:</u> line BC is parallel to line ED m∠ABC = 70° m∠CED = 30°

<u>Prove:</u> m∠BEC = 40°

Statement Justification

1. line BC is parallel to line ED - Given

2. m∠ABC = 70° - Given

3. m∠CED = 30° - Given

4. m∠BEC + m∠CED = m∠BED - Angle Addition Postulate

5. m∠ABC = m∠BED - Corresponding Angles Theorem

6. m∠BEC + 30° = 70° - Substitution Property of Equality

7. m∠BEC = 40° Subtraction Property of Equality

Find the least common denominator of 7/20 and 3/28

Genrish500 [490]

Answer:

140

Step-by-step explanation:

We have been given two fractions $\frac{7}{20}$ and $\frac{3}{28}$ . We are asked to find the least common denominator of both fractions.

To find the least common denominator of both fractions, we will find least common multiple of 20 and 28.

Prime factorization of 20: $2\times 2\times 5$

Prime factorization of 28: $2\times 2\times 7$

Least common multiple of 20 and 28 would be: $2\times 2\times 7\times 5=140$ .

Therefore, the least common denominator of both fractions would be 140.
