What is the solution to the system of equations below? 2x-y=10 and y=-1/2x+5​

Answers

Answer 1
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.

How many 1/2's are in 2 and 1/2?

Answers

Answer:

5

Step-by-step explanation:

there are 2 halves in one whole. Knowing that we will multiply, 2x2. That is 4, and then we will add the other half to our amount of halves to see the answer.

the answer is 5

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.

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 = ?

Answer = A
Explanation:
If you look at the original points on ABCD, you can see that if multiplied by 0.5 give A’B’C’D’.
For example,
Point A = (-4,1)
If you multiply -4 by 0.5 it’s -2 and if you multiply 1 by 0.5 it’s 0.5.
Point A’ = (-2,0.5)
This means that choice A is correct (you can double check the other points as well, it’ll all be correct.)

Cindy has a poster in the shape of a parallelogram.

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:
