Could anyone help please

Answer:

[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]

Step-by-step explanation:

[tex]\frac{3}{4} x-2=\frac{2}{5}[/tex]

3/4 and 2/5 have a common denominator which is twenty so you can rewrite the equation with just knowing that

[tex]\frac{3}{4} =\frac{15}{20}[/tex]

[tex]\frac{2}{5} =\frac{8}{20}[/tex]

[tex]\frac{15}{20} x-2=\frac{8}{20}[/tex]

You can then multiply both sides by twenty to solve this equation.

Hope this helps.

15x = 48

Step-by-step explanation:

[tex]\begin{aligned}\rm\frac{3}{4}x-2&=\rm \frac{2}{5}\to(multiplied~by~20)\\\rm(20)\frac{3}{4}x-(20)2&=(20)\frac{2}{5}\\\rm 15x-40&=8\\\rm 15x&=8+40\\\rm 15x&=48\end{aligned}[/tex]

Answer:

[tex]\frac{27}{2}[/tex]

Step-by-step explanation:

Okay, first whenever you divide a fraction, you're going to want to multiply by the reciprocal. The reciprocal or the inverse in this case is [tex]\frac{3}{2}[/tex].

Multiply 9 with the integer. Also, remember that numbers that aren't fractions like 9 can be written as a fraction with a 1 in the denominator. 9 = [tex]\frac{9}{1}[/tex]. So,

[tex]\frac{9}{1}[/tex] × [tex]\frac{3} {2}[/tex]. Multiply across. The numerators together (9 with 3) and the denominators together (2 with 1).

9 × 3 = 27 and 1 × 2 = 2. As a fraction the answer will come out to be [tex]\frac{27}{2}[/tex].

Answer:

C right 18, down 12

Step-by-step explanation:

Well firstly,

you should focus on the x in both the previous and after location of the object.if you minus 12 from the after point (12,-2) by -6 from the previous point (-6,10) for the object, you'll get 18 which is positive, which means that the object will moves to the right side of the graph →

12 - (-6)

= 18

Next,

you should now focus on the y in both the previous and after location of the object.you should minus -2 by 10 and you'll get -12, which means that the object will moves to the down side of the graph ↓

-2 - 10

= -12

So, the object will move 18 boxes to the right and 12 boxes down to achieve the after, final or last location as stated in the question (12,-2)

In the given figure, the Angle x forms Alternate exterior angle pair with 143°, so

(since, Alternate Exterior Angles have equal measures)

Answer:

107

Step-by-step explanation:

Angle 1

When a line is passes through a straight line, the two angles must equal 180 degrees.  Since you know the one angle is 81, then angle 1 is 180 - 81 or

99 degrees.

Angle 2

You can determine the angle that is opposite of the 91 angle.  These two angles must add up to 180.  So the angle to the right of 91 must be 89.

89 + 91 = 180

You were told lines c and d are parallel.  Based on that, the angle you just calculated must be equal to angle 2 or 89 degrees.

Angle 3

Again, you know that lines c and d are parallel. When a line crosses over two parallel lines, the outer opposite angles would be equal to each other.

So angle 3 is equal to the angle marked as 81 degrees.

Angle 1 + Angle 2 - Angle 3 = 107

Answer:

Step-by-step explanation:

here's a somewhat answer, and how to solve it

lets assume that all "60 cm wire is used to make a rectangle"

h = a

w = a + 3

the perimeter of the rectangle is

a + a + a + 3 + a + 3 = 60

4a = 54

a = 13.5

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

height = 13.5

width = 16.5

BUT, the problem says "not all the wired is used"

how much? 59? 58? 57.... the lowest value for the shortes side is 1

h = 1

w = 1 + 3 = 4  

perimeter : 1 +4 + 4 + 1 = 6cm

Answer:

-32

Step-by-step explanation:

the expression would be n ( 8 - 6 ) = 64. first solve whats in the parentheses, which is -2. then multiply n by -2, which is -2n = 64. divide 64 by -2, which is -32. to check, multilpy -2 by -32, which is 64. therefore the number is -32.
