Answer:
Step-by-step explanation:
Isolate the variable of y from one side of the equation.
-14=5(3y-10)-5y
<u>First, switch sides.</u>
Use the distributive property.
<u>DISTRIBUTIVE PROPERTY:</u>
A(B-C)=AB-AC
5(3y-10)
Multiply by expand.
5*3y=15y
5*10=50
15y-50-5y
15y-5=10y
= 10y-50
10y-50=-15
Add by 50 from both sides.
10y-50+50=-15+50
Solve.
10y=35
Then, you divide by 10 from both sides.
10y/10=35/10
Solve.
Divide the numbers from left to right.
35/10=7/2
y=7/2
Divide is another option.
7/2=3.5
- <u>Therefore, the correct answer is y=7/2.</u>

b:with regards to the square I don't think you can really prove the statement
Answer:
x = 0
y = 5
z = -5.
Step-by-step explanation:
X-5y-z=-20
-2x-y-6z=25
-x-4y-z=-15
Add equation 1 and 3:
-9y - 2z = -35 .......... A
Multiply the first equation by 2:
2x - 10y - 2z = -40
Now add this to equation 2:
-11y -8z = -15.............B
Now multiply equation A by -4:
36y + 8x = 140.........C
Add equations B and C:
25y = 125
y = 5.
Substitute for y in equation A:
-9*5 - 2z = -35
2z = -45 + 35 = - 10
z = -5.
Now find x by substituting for y and z in the first equation:
x - 5(5) - (-5) = -20
x - 20 = -20
x = 0.
Answer:
<em>Abraham Lincoln </em>
Step-by-step explanation:
<u><em>Abraham Lincoln was the 16th president of the United States and is regarded as one of America's greatest heroes due to his role as savior of the Union and emancipator of enslaved people. Lincoln's distinctively humane personality and incredible impact on the nation have endowed him with an enduring legacy.
With his ability to command a room, give a powerful speech and negotiate, he is regarded as one of the best presidents in American history. As a leader, Lincoln was determined to hold together a nation that was falling apart at the seams. </em></u><u><em>Abraham Lincoln was voted the best US president in a survey where nearly 100 historians and biographers rated past commanders in chief on 10 leadership qualities</em></u>
