Answer:

the first one n second one

Answer:

7.35

Step-by-step explanation:

If you solve the equation

2.5– 1.75 = 5(7 – 0.5)

Then...

x=7.35

Answer:

7.35

Step-by-step explanation:

Answer:

x = -56

Step-by-step explanation:

0.75(x + 20) = 2 + 0.5(x - 2)

0.75x + 15 = 2 + 0.5x - 1

0.25x = -14

x = -14/0.25

x = -56

Answer:

the third one (2,-18)

Step-by-step explanation:

Answer:

A. 58

Step-by-step explanation:

70° + m<3 + 52° = 180°

m<3 = 58°

Answer:

A. 58°

Step-by-step explanation:

here's your solution

==> 70° + 52° + angle 3 = 180°. [linear pair]

==> angle 3 + 122° = 180°

==> angle 3 = 180° - 122°

==> angle 3 = 58°

Answer:

a)  (2 x 1000) + (5 x 100)

b)  5^4 × 2²

c)  ??

Step-by-step explanation:

b) 2500 = 25 x 100

25 = 5 x 5

100 = 25 x 4 = 5 x 5 x 2 x 2

Answer:

117π=367.38

Step-by-step explanation:

r=d/2=3

V=πr2h=π·3²·13=117π=367.38

Answer:

Width __6___ cm

Length __12__ cm

Step-by-step explanation:

hello :

x : the width   and y : Length    P : the  perimeter

P=2(x+y )        but : P=36cm  and : y = 2x

36 = 2(x+2x)

36 = 2(3x)

6x =36   so : x=6 cm   and y = 2×6=12cm

Step-by-step explanation:

If breadth is b,then length will be 2b,so

Perimeter=36

2(2b+b)=36

3b=18

b=6,so,l=2×6=12

So,length is 12 and breadth is 6,

Explanation: A 45°-45°-90° triangle is a special right triangle that has two 45-degree angles and one 90-degree angle. The side lengths of this triangle are in the ratio of; Side 1: Side 2: Hypotenuse = n: n: n√2 = 1:1: √2. The 45°-45°-90° right triangle is half of a square.

Answer: [tex]171.4\%[/tex]

Step-by-step explanation:

Given

Time is extended from 28 days to 76 days

The percentage increase is given by

[tex]\Rightarrow \dfrac{\text{New-original value}}{\text{original value}}\times 100[/tex]

Putting values

[tex]\Rightarrow \dfrac{76-28}{28}\times 100=\dfrac{48}{28}\times 100\\\\\Rightarrow 171.4\%[/tex]

Thus, the percentage increase in time is [tex]171.4\%[/tex]

Answer:

k = 5

Step-by-step explanation:

The standard form of an equation representing proportionality is

y = kx ← k is the constant of proportionality

y = 5x ← is in standard form

with k = 5

Answer:65.15

Step-by-step explanation:

Answer:

$67.15

Step-by-step explanation:

100% - 15% = 85%

original price = 79

85% of 79 = sale price

85/100 * 79 = sale price

67.15

Answer:

10√6 ; √5/6 ; 42√14

Step-by-step explanation:

1)  - factorise 240

240/ 2 = 120

120/2 = 60

60/2 = 30

30/2 = 15

15/3 = 5

5/5 = 1

240 = 2^4 * 3 * 5

- simplify [tex]\sqrt{2^4 * 5 * 3}[/tex]. We can in particular simplify [tex]\sqrt{2^4}[/tex]  by dividing the index of the radius and the exponent by 2

[tex]2^2\sqrt{5*3} = 4\sqrt{15}[/tex]

- factorise 12

12/2 =.6

6/2 = 3

3/3 = 1

12 = 2^2 * 3

- simplify [tex]\sqrt{2^2 *3}[/tex]

[tex]\sqrt{2^2 * 3} = 2\sqrt{3}[/tex]

- divide [tex]4\sqrt{15} with 2\sqrt{3}[/tex]

number : number = 4/2 = 2

square : square = √15 / √3 = √5

[tex]2\sqrt{5}[/tex]

- multiply √30 with 2√5

number x number = 2x1 = 2

square x square = √30 x √5 = √150

2√150

- factorize 150

150/ 2 = 75

75/3 = 25

25/5 = 5

5/5 = 1

150 = 5^2 x 2 x 3

- simplify [tex]\sqrt{5^2 * 2 * 3}[/tex]

[tex]\sqrt{5^2 * 2 * 3} = 5\sqrt{6}[/tex]

- multiply 2 and 5

10√6

2)  remember that a division of two terms with the same square can be rewrite as [tex]\sqrt{x/y} = \sqrt{x} / \sqrt{y}[/tex]

- rewrite the expression in this way

[tex]\sqrt{5} / \sqrt{9} + \sqrt{5} / \sqrt{144} - \sqrt{5} / \sqrt{16}[/tex]

- solve the squares of the denominators

√5/3 + √5/12 -√5/4

- rewrite the fraction with the same denominator = 12

(4√5 + √5 - 3√5)/12

- simplify the numerators by sum the numbers

2√5/12

- divide 2 and 12

√5/6

3)

- multiply 3√2 and √14

number x number = 3 x 1 = 3

square x square = √2 x √14  = √28

3√28

- factorise 28

28 = 2^2 x 7

- simplify [tex]\sqrt{2^2 *7}[/tex]

[tex]\sqrt{2^2 *7} = 2\sqrt{7}[/tex]

- multiply 3 and 2

6√7

- factorise 98

98/2 = 49

49/7 = 7

7/7 = 1

98 = 7^2 * 2

- simplify [tex]\sqrt{7^2 * 2}[/tex]

[tex]\sqrt{7^2 * 2} = 7\sqrt{2}[/tex]

- multiply 6√7 and 7√2

number x number = 42

square x square = √14

42√14

Answer:

y = 2x+14

Step-by-step explanation:

So first of all simplify 2(x+2)

Result is 2x+4

Y-10=2x+4

Now add 10 to both sides and that's how you get your answer

The correct answer is A

A) [tex]8(-10)=10(-10)+20[/tex] becomes [tex]-80 = -80[/tex]

B) [tex]8(-35)=10(-35)+20[/tex] becomes [tex]-280 \neq -330[/tex]

C) [tex]8(-23)=10(-23)+20[/tex] becomes [tex]-184 \neq -210[/tex]

D) [tex]8(-40)=10(-40)+20[/tex] becomes [tex]-320\neq -380[/tex]
