Which equation finds the area of a square with a side length of 5n4 units?

Answers

Answer 1

Answer:

25n^8

Step-by-step explanation:

Area of a square is length×length

Length=5n^4

Area=5n^4×5n^4

=(5×5)(n^4+4)

=(25)(n^8)

=25n^8

So the area of a square is 25n^8

Answer 2

Answer: The answer is to this question is 25n^8

Solve each system of linear equations by substitutions.1. 3x-2y=9 y=2x-7
2. Y=x-4 2x+y=5
3. X+4y=6 y=-x+3

Answers

1.
$3x-2y=9 \n y=2x-7 \n \n \hbox{substitute 2x-7 for y in the 1st equation:} \n 3x-2(2x-7)=9 \n 3x-4x+14=9 \n -x=9-14 \n -x=-5 \n x=5 \n \n y=2x-7=2 * 5-7=10-7=3 \n \n \boxed{(x,y)=(5,3)}$

2.
$y=x-4 \n 2x+y=5 \n \n \hbox{substitute x-4 for y in the 2nd equation:} \n 2x+x-4=5 \n 3x=5+4 \n 3x=9 \n x=3 \n \n y=x-4=3-4=-1 \n \n \boxed{(x,y)=(3,-1)}$

3.
$x+4y=6 \n y=-x+3 \n \n \hbox{substitute -x+3 for y in the 1st equation:} \n x+4(-x+3)=6 \n x-4x+12=6 \n -3x=6-12 \n -3x=-6 \n x=2 \n \n y=-x+3=-2+3=1 \n \n \boxed{(x,y)=(2,1)}$

Maria bought seven boxes. A week later half of her boxes were destroyed in a fire. There are only 22 boxes left. With how many did she start?

Answers

The equation is (x+7)/2=22

X is what we need to find out. (I’m not sure if you are in algebra yet so I’m sorry if you’re not)

First we should give both sides the same denominator (22=22/1)

(X+7)/2=22/1 now we can change 22/1 to 44/2
(X+7)/2=44/2

Now since we are trying to find x, we can remove the denominator to solve for x and make it easier.

x+7=44 subtract 7 from both sides
x=37

***so your answer is 37***

16. The answer is 18 1-cup candle molds because, there are 8 fluid ounces in 1 cup so, 144÷8=18.

17. The answer is 2 1-pint containes because, there are 16 fluid ounces in 1 pint, and 32÷16=2.

16. The answer is 18 because there are 8 fl oz in a cup, so 144 ÷ 8 = 18.

17. The answer is 2 pints because there are 16 fl oz in a pint, so 16 x 2 = 32

What is 6 1/2 - 1 9/10

Answers

Find common denominator which is 10 then find the equivalent fraction for 6 1/2 = 6 5/10.
Now you have 6 5/10 - 1 9/10, but since first numerator is less than the second numerator you need to borrow from the whole number. 6 5/10 = 5 10/10 + 5/10 = 5 15/10. Now just subtract the whole numbers and the numerators.
5 15/10 - 1 9/10 = 4 6/10 simplify to 4 3/5.

The value of the solution after subtraction is,

⇒ 4 3/5

We have to give that,

An expression to solve,

⇒ 6 1/2 - 1 9/10

Now, change the fraction into an improper fraction,

⇒ 6 1/2 - 1 9/10

⇒ 13/2 - 19/10

⇒ 65/10 - 19/10

⇒ (65 - 19) / 10

⇒ 46/10

⇒ 23/5
