Answer:

4x-2y=0

Step-by-step explanation:

so you need to subtract

(3x+2y=22)-(-x+4y=22)

Use distributive property and take away parenthesis

3x+2y=22+x-4y=-22

----------------------------

3x+2y=22

x-4y=-22

------------------------------

4x-2y=0

Answer:

( $\frac{22}{7}$ , $\frac{44}{7}$ )

Step-by-step explanation:

3x + 2y = 22 ....... (1)

- x+ 4y = 22 ........ (2)

3 × (2) + (1)

(3x - 3x) + (2y + 12y) = 22 + 66 ( variable "x" is eliminated )

14y = 88

y = $\frac{44}{7}$

- x + 4( $\frac{44}{7}$ ) = 22

x = $\frac{176}{7}$ - $\frac{154}{7}$ = $\frac{22}{7}$

(  $\frac{22}{7}$  ,  $\frac{44}{7}$  )

Find the solution to the system of equations. 4x + 3y = –1 3x – 9y = 33 solution = ( , )

tensa zangetsu [6.8K]

Answer:

(x, y) =(2,-3)

Step-by-step explanation:

4x+3y=-1

3x-9y=33 /:3

4x+3y=-1.....(1)

x-3y=11... (2)

(1)+(2): 5x=10

x-3y=11

x=10/5

x-3y=11

x=2

2-3y=11

x=2

-3y=11-2

x=2

-3y=9

x=2

y=9/(-3)

x=2

y=-3

(x,y)=(2,-3)

Tim dug a hole that was 16 1/2 inches deep.He left a pile of dirt next to the hole that was 8 3/4 inches high.Show how you could

Viktor [21]

Answer:

14 inches

Step-by-step explanation:

Length of the hole = 16(½) inches

Length of the dirt = 8(¾)inches

The distance between the top of the pile to the bottom of the hole = ?

Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.

Distance from the top to the bottom = length of dirt + length of the hole

Length of dirt = 8×¾ = 6 inches

Length of the hole = 16 × ½ = 8 inches

Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches

Distance from the top of the dirt to the bottom of the hole = 14 inches

Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left

Distance left = length of hole - length of dirt

Distance left = 8 - 6 = 2 inches .

But what the question requested was the distance from the top of the dirt to the bottom of the hole

ANSWER PLZ ASAP!!!!!!!!!!!!!!

hammer [34]

Just substitute r with 357 and solve.

= 1/7(357) + 3(1/7(357))

= 51 + 3(51)

= 51 + 153

= 204

Therefore, Eliza read 204 in those 3 days.

Best of Luck!

A right triangle has one side that measures 4 in. The angle opposite that side measures 80°. What is the length of the hypotenus

Sunny_sXe [5.5K]

Since you have an angle and at least one side you can use either sine, cosine or tan. For this question, you would use sine like above. Hope this helps!

Triangles G H L and K H J are connected at point H. Angles Angles L G H and H K J are congruent. Sides G H and H K are congruent

stira [4]

The congruence theorem that can be used is: B. ASA

<h3>What is the ASA Congruence Theorem?</h3>

If we have two triangles that have two pairs of corresponding congruent angles (e.g. ∠LGH ≅ ∠HKJ and ∠LHG ≅ ∠KHJ), and a pair of corresponding congruent sides (e.g. GH ≅ HK), the triangles are said to be congruent triangles by the ASA congruence theorem.

Therefore, triangles GHL and KHL in the image given are congruent triangles by the ASA congruence theorem.
