I Need Help With The Equation Inserted In The Picture.

Answers

Answer 1

Answer:

x = 4

-4x+21 => 5

Step-by-step explanation:

The given triangle in the picture is isosceles triangle which means that two sides of the triangle are equal.

So,

[tex]Side\ 1: -4x+21\\Side\ 2: -4x+21\\Side\ 3: 6\\Perimeter = 16[/tex]

Now

Putting all the values in equation for perimeter

[tex]Side\ 1+Side\ 2+Side\ 3 = 16\\-4x+21 -4x+21 + 6 =16\\-8x +48 = 16\\-8x = 16-48\\-8x = -32\\\frac{-8x}{-8} = \frac{-32}{-8}\\x = 4[/tex]

Putting x = 4 in side 1

[tex]=-4(4)+21\\= -16+21\\=5[/tex]

Hence,

x = 4

-4x+21 => 5

it’s due by midnight and can you also tell me how you got the answer

Answers

Answer:

a=10

Step-by-step explanation:

distribute on both sides to get

5a-10=20+2a

add/subtract like terms

5a-2a=3a

20+10=30

so the equation is

3a=30

divide 30 by 3 and you get 10

Answer:

a = 10

Step-by-step explanation:

[tex]5(a - 2) = 2(10 + a) \\ \\ 5a - 10= 20 + 2a\\ \\ 5a - 2a= 20 + 10\\ \\ 3a = 30\\ \\ a = \frac{30}{3} \\ \\ \huge \red{ \boxed{a = 10}}[/tex]

jessica will babysit children for $8 an hour. ciara will babysit for an appointment fee of $12 and $4 an hour. how many hours would they need to work to earn the same amount of money? if a baby sitter was needed for 5 hours, who would be less expensive?

Answers

Answer:

Answer are in bold below

Step-by-step explanation:

Question: 1

Jessica = $8

Ciara = $12 + 4 $16

Now we times both values.

16 x 8 = $128

8 x 16 = $128

They would both need to work 8 hours ft=or the same money.

Question 2:

$8 x 5 = $40

$16 x 5 =$80

Jessica will be less expensive.

Answer: 3 hours

Jessica=$8

Ciara= $4 + $12

8*3= $24

4*3= $12 +$12= $24

Because Ciara has an additional $12 fee, you have you add it on to her total.

Find the equation of the line that is parallel to the given line and passes through the given point.

y = −5x + 1; (5, 7)

Answers

See attachment for math work and answer.

The equation we are looking for is parallel to the given equation. This means both equations have the same slope.

Answer:

y = -5x + 32

Step-by-step explanation:

y = -5x + 1

=> (d): 5x + y - 1 = 0

d' is parallel to the given line and passes through the given point

=> (d'): passes through (5;7)

           // (d): 5x + y - 1 = 0

=> (d'): 5x + y - 32 = 0 <=> y = -5x + 32

On multiple-Choice history Test, rita received a mark of 80%. She answer 32 correctly

Answers

Let total number of questions be x.

According to the question,

80% of x is 32

or 80/100 × x = 32

or x = 32 ÷ 80/100

or x = 32 × 100/80

or x = 32 × 10/8

or x = 4 × 10

or x = 40

So, total number of questions is 40.

Step-by-step explanation:

- 3x + 2y = - 5
