FRAME AN EQUATION AND SOLVE IT .NEED ASAP


3 is added to a number and the result is multiplied by 4 to get 20.​

Answers

Answer 1

Answer:

[tex]\fbox {Required equation : 4(x + 3) = 20}[/tex]

[tex]\fbox {Result : x = 2}[/tex]

Step-by-step explanation:

Let our number be x.

1) 3 is added to this number.

x + 3

2) It is multiplied by 4.

4(x + 3)

3) It is equated to 20.

4(x + 3) = 20

∴ This is our framed equation.

Steps to solve :

1) Divide by 4 on both sides.

1/4 x 4(x + 3) = 20/4x + 3 = 5

2) Subtract 3 on both sides.

x + 3 - 3 = 5 - 2x = 2

∴ The number is 2.

Answer:

im not smart

Step-by-step explanation:

A store sells hardcover books for $8 and paperback books for $5. You buy 9 books, represented by the equation x+y=9, where x is the number of hardcover books and y is the number of paperback books. The equation 8x+5y=51 represents the total cost. How many of each type of book did you buy?

Answers

Answer:

Step-by-step explanation:

x+y = 9

y = 9-x

8x + 5y = 51

8x + 5(9-x) = 51

8x + 45 - 5x = 51

3x = 6

x = 2

y = 9-x = 7

Two hardcover books and seven paperback books.

dinner out at nice restaurant cost $45 plus a 20% tip what was the total cost of dinner ​

Answers

Answer:

$54 because the tip would be $9 so just add 45 and 9

Answer:

$54

Step-by-step explanation:

Since we are adding a 20% tip to the original cost of 45, the equation is

45+(0.2)(45),

since we want to add 20% of 45 to the original 45.

Solving that gives us 54.

Answer:

Congruent pairs of triangles:

ΔABD ≅ ΔDCB

AB≅CD - given∠ABD ≅ ∠CDB - givenBD≅DB - common sideSAS - two sides and the included angle

ΔABD ≅ ΔEFD - SAS

AB≅EF - given∠ABD ≅ ∠EFD - given∠ADB ≅ ∠EDF - vertical anglesAAS - two angles and non-included side

By using the above two we can state that:

ΔBDC ≅ ΔDFE - by ASA or SSS

because

BD ≅ DF (corresponding parts)  AD ≅ BC  (corresponding parts) AD ≅ ED  (corresponding parts) and  therefore BC ≅ ED

We can't prove that:

ΔAGD is congruent with any of the others as not enough information

There is one side and one angle and we can' t get two angles or two sides with included angle. Maximum we can get is SSA which doesn't guarantee the congruence.

Ten more than four times a number is equal to the difference between 73 and three times the number. Find the number.

Answers

Answer:

let x be the number then,

according to question ,

10+4x=73-3x

or, 4x+3x=73-10

or, 7x= 63

or, x= 63÷7

or,x=9 ans

hence , the number is 9

What geometric term describes PQ and RS

Answers

Answer:

perpendicular lines

Step-by-step explanation:

Two lines in a plane are said to be perpendicular if they intersect in such a way that the angles formed between them are right angles. In the adjoining e, lines PQ and RS intersect at 0 such that ∠ROQ = ∠ ROP = ∠POS = ∠QOS = 90°. Therefore, we say that PQ is perpendicular to RS

In addition to the information given in the drawing, which statement would be sufficient to prove

that STW-XYZ?

Number 5

Answers

Answer:

[tex]SW= 15[/tex] and [tex]TW= 24[/tex]

Step-by-step explanation:

Given

See attachment for the triangles

Required

Which additional statement proves the similarity of both triangles

From the attachment:

[tex]ST = 27\\XY = 9\\YZ = 8\\XZ = 5[/tex]  

The similar sides of both triangles are: ST and XY

So:

[tex]Ratio = ST : XY[/tex]

[tex]Ratio = 27 : 9[/tex]

Divide by 9

[tex]Ratio = 3 : 1[/tex]

Another similar sides are: TW and YZ

So:

[tex]TW : YZ = TW : 8[/tex]

Equate both ratios:

[tex]TW : 8 = 3 : 1[/tex]

Represent as fraction

[tex]\frac{TW }{ 8 }= \frac{3 }{ 1}[/tex]

[tex]\frac{TW }{ 8 }= 3[/tex]

Multiply both sides by 8

[tex]8 * \frac{TW }{ 8 }= 3*8[/tex]

[tex]TW= 3*8[/tex]

[tex]TW= 24[/tex]

Another similar sides are: SW and XZ

So:

[tex]SW:XZ = SW:5[/tex]

Equate both ratios:

[tex]SW:5 = 3:1[/tex]

Represent as fraction

[tex]\frac{SW}{5} = \frac{3}{1}[/tex]

[tex]\frac{SW}{5} = 3[/tex]

Multiply both sides by 5

[tex]5*\frac{SW}{5} = 3*5[/tex]

[tex]SW = 3*5[/tex]

[tex]SW = 15[/tex]

So, the statement that proves the similarity of the triangles is:

[tex]SW= 15[/tex] and [tex]TW= 24[/tex]
