Answer:

1 = -x

Step-by-step explanation:

group like terms together so

this 5 + 4x - 7 = 4x -3 - x

becomes this 5 - 7 + 3 = 4x -4x -x

then simplify     1 = - x  

Answer:

[tex]c=85[/tex]

Step-by-step explanation:

[tex]c=180-a-b[/tex] where [tex]a=62[/tex] and [tex]b=33[/tex]

Step 1.  Substitute a for 62 and b for 33

[tex]c=180-(62)-(33)[/tex]

Step 2. Subtract [tex](180 - 62)[/tex]

[tex]c=118-33[/tex]

Step 3. Subtract (again)

[tex]c=85[/tex]

so c = 85

Coordinates of B is [tex](\frac{4}{11} ,\frac{13}{11} )[/tex] that divides AC five-sixths of the way from A to C

Given :

AC with A(4.-7) and C(-4, 11), if point B divides AC five-sixths of

the way from A to C

From the given information , B divides AC internally in the ratio of AB to BC is 5:6

Lets apply section formula to find coordinates of B

[tex](\frac{mx_2+nx_1}{m+n} ,\frac{my_2+ny_1}{m+n} )[/tex]

m:n is the ratio 5:6

A is (x1,y1) that is (4,-7)

B is (x2,y2) that is (-4,11)

Substitute the values inside the formula

[tex](\frac{mx_2+nx_1}{m+n} ,\frac{my_2+ny_1}{m+n} )\\(\frac{(5)(-4)+6(4)}{5+6} ,\frac{5(11)+6(-7)}{5+6} )\\(\frac{4}{11} ,\frac{13}{11} )[/tex]

Coordinates of B is [tex](\frac{4}{11} ,\frac{13}{11} )[/tex]

Answer:

y= [tex]-\frac{4x}{9}[/tex] + [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

6=4x+9y

First swap sides so that all variables are on the left side.

4x+9y=6

Subtract 4x from both sides.

9y=6-4x

Divide both sides by 9, this undoes the multiplication.

y=[tex]\frac{6-4x}{9}[/tex]

Divide 6-4x by 9.

y= [tex]-\frac{4x}{9}[/tex] + [tex]\frac{2}{3}[/tex]

Answer:

The three skirts each cost $24.99

The two skirts priced $3 below the others cost $21.99

Step-by-step explanation:

Let [tex]a[/tex] represent the amount of money the "three skirts at one price" costs.

Let [tex]b[/tex] represent the amount of money the "2 skirts priced $3 below the others" costs.

From there, we can form the system of equations and solve:

[tex]3a+2b=118.95\\a-3=b\\\\3a+2(a-3)=118.95\\3a+2a-6=118.95\\5a-6=118.95\\5a=124.95\\a=24.99\\\\a-3=b\\24.99-3=b\\21.99=b\\b=21.99[/tex]

Answer: 170.25

Step-by-step explanation:

Quick version

Step 1: Convert 15 percent to decimal

[tex]15\%\:=\frac{15}{100}\\\\= 15 \%[/tex]

Step 2: Multiply 0.15 to 1135

[tex]0.15\cdot \:1135\\\\=170.25[/tex]

170.25 is 15 percent of 1135.

Answer:

170.25 is the solution.

Step-by-step explanation:

Let's find 15% of 1135.

Value of the percentage is,

→ 15 ÷ 100

→ 0.15

Let's find the solution,

→ 1135 × 0.15

→ 170.25

Thus, the answer is 170.25.

Answer: -30

Step-by-step explanation:

[tex] {(8 - 10)}^{2} - 30 \div 5 \times 6 + 2[/tex]

BODMAS

let's first solve the bracket:

[tex] = {( - 2)}^{2} - 30 \div 5 \times 6 + 2 \\ = 4 - 30 \div 5 \times 6 + 2[/tex]

then let's divide:

[tex] = 4 - (30 \div 5) \times 6 + 2 \\ = 4 - 6 \times 6 + 2[/tex]

then let's multiply:

[tex] = 4 - (6 \times 6) + 2 \\ = 4 - 36 + 2[/tex]

simplify:

[tex] = - 30[/tex]

If the value of the scale factor is 2.5 then the coordinates of point C of the image of the triangle after dilation is (12.5, 5).

Dilation means the changing of the size of the object without changing the shape. The size of the object may be increased or decreased based on the scale factor.

△ABC has vertices A(2, 2), B(3, 4), and C(5, 2).

Then the coordinates of point C of the image of the triangle after a dilation centered at the origin with a scale factor of 2.5.

Then the dilated point C' will be given as

C' = Scale factor × C

C' = (2.5 × 5, 2.5 × 2)

C' = (12.5, 5)

More about the dilation link is given below.
