x= 10/3 y=20/3

You can substitute the second equation into the first one because the second one tells you what y is so you plug in to the first equation.

8v + 6v + 3v

=> 17v

3(v + 2) + 11v

=> 3v + 6 + 11v

=> 6 + 14v

2(4v + 8v)

=> 8v + 16v

=> 24v

8v + 9v - v

=> 16v

The last option is the only one that equals 16v, therefore, it would be the right answer.

Help me plz, again...

Answers

Answer:

1. C) 4 ft

2. B) 3 yds

3. C) 15840 ft

4. D) 128 oz

5. A) 105 oz

Step-by-step explanation:

For No. 1, to find how many feet, you can divide the number of inches by how many inches in a foot, or 12:

48/12 = 4 ft

For No. 2, to find how many yards, you would do the same. This time, there's 3 ft in a yard. You can also develop strategies for solving these. A ratio is a good way to visually see the problem:

3 ft      9 ft

-----  =  -----

1 yd     ? yd

Cross multiply:

3 · ? = 9

? = 3

For No. 3, to find how many feet in 3 miles, first recall how many feet in 1 mile. That's 5280 ft.

We want 3 of those, so you would multiply it:

5280 · 3 = 5280 + 5280 + 5280

               = 10560 + 5280

               = 15840

For No. 4, you can use a ratio again:

16 oz       ? oz

-------- =  --------

 1 lb        8 lb

Cross multiply:

16 (8) = ?

128 = ?

For No. 5, you can use the same ratio as No. 4:

16 oz       ? oz

-------- =  --------

 1 lb        6.5 lb

Cross multiply:

16 (6 1/2) = ?

(16 · 6) + (16 · 1/2) = ?

96 + 8 = ?

104 = ?

This is because if you divide 2 and 1/2 by 1/2 you would get 5. So if you add 1/2 + 1/2 + 1/2+ 1/2+1/2 you would get 2 and a 1/2. If you count all the half’s you added there is 5.

What is the area of this parallelogram?

Answers

Answer:

3.60

Step-by-step explanation:

took the test

Answer:

Area of the parallelogram is 3.69 ft²

Step-by-step Explanation:

We have,

A parallelogram in shape of a poster.And we need to find the area of parallelogram.

For solving,

The parallelogram is divided in 3 parts. 2 triangles and one rectangle.We will find all of there areas separately and then will add it up to have the final area of parallelogram.

★Area of triangles:

= ½ × base × height

= ½ × 0.5 × 1.5

= 0.5 × 0.75

= 0.375 ft²

Since there are to triangles of same size,

= 2 × 0.375

= 0.75 ft²

★Area of rectangle:

= Length × breadth

= 1.9 × 1.5

= 2.85 ft²

Final area of parallelogram:

= Area of both triangles + area of rectangle

= 0.75 + 2.85

= 3.60 ft²

Ok so 1. I am in AP Calculus BC and I legit just fully learned how to do exponents (I had a rough year in algebra 1 lol) so don't feel bad. And 2. It's really simple. When you multiply exponents you so just add them so x^2 * x^3=x^5. This makes sense visually since x^3 is x*x*x and x^2 is x*x and when you multiply that out you get x*x*x*x*x. Division is also pretty simple and all you have to do is subtract them. (There is a reason for this but its not important but I'll explain it anyways. Basically when you divide it is the same thing as multiplying by a negative exponent so x^3 / x^2 = x.) When you have multiple variables all you have to do is combine like terms so if you have something like xy^2*xy^4 you would get (x^2)(y^6). As for your problems, here:
