Answer:

Which expression is NOT equivalent to -20? O A (-80) 4 80 В — (0) ОО с (30) 80 ор 80 (-4 -

Step-by-step explanation:

To solve linear equations, we must perform inverse operations on both sides of the equal sign to cancel values out.

We perform inverse operations to combine like terms. This means to get x to one side and everything else on the other.

[tex]5x+7=15[/tex]

Because 7 is being added to x, subtract it from both sides:

[tex]5x+7-7=15-7\\5x=8[/tex]

Because x is being multiplied by 5, divide both sides by 5:

[tex]\dfrac{5x}{5}=\dfrac{8}{5}\\\\x=\dfrac{8}{5}[/tex]

Therefore. [tex]x=\dfrac{8}{5}[/tex].

[tex]7x+4=5x-18[/tex]

Here, we can group all the x values on the left side of the equation. Subtract 5x from both sides:

[tex]7x+4-5x=5x-18-5x\\2x+4=-18[/tex]

To isolate x, subtract 4 from both sides:

[tex]2x+4-4=-18-4\\2x=-22[/tex]

Divide both sides by 2:

[tex]\dfrac{2x}{2}=\dfrac{-22}{2}\\\\x=-11[/tex]

Therefore, [tex]x=-11[/tex].

[tex]\qquad \qquad\huge \underline{\boxed{\sf Anѕwєr}}[/tex]

To get the number of terms in an expression we have to add the like terms, and after that the different terms separated by mathematical operators (+ and -) are the required number of terms !

That is :

[tex]\qquad \sf  \dashrightarrow \: 55 + 14m - 2n + 3p[/tex]

here, since we don't have like terms, let's skip the first part.

So, total number of terms = 4

Answer: 198cm

Step-by-step explanation:

We are given the dimensions of a rectangular prism;

3cm 9cm and 6cm

We are required to determine its surface area;

We need to know that;

Surface area of a rectangular prism is given by;

A = 2(WL+HL+WH)

Where L, W and H are length , width and height respectively;

Assuming;

Width is 3 cm

Length is 9 cm, and

Height is 6 cm

Then;

Area = 2 ( (3×9) + (6×9) + (3×6))

       = 2(99)

      = 198 cm²

Therefore, the area of the rectangular prism is 198 cm²

Answer:

x = 13; y = 13; z = 18

Step-by-step explanation:

In a rhombus, opposite angles are congruent and consecutive angles are supplementary.

6x + 8 = 86

6x = 78

x = 13

7y + 3 + 86 = 180

7y + 89 = 180

7y = 91

y = 13

5z + 4 + 86 = 180

5z + 90 = 180

5z = 90

z = 18

Answer:

x=13

y=13

z=18

Hi!

The point-slope formula looks like this:

y-y1=m(x-x1)

in this case

y1=1

m=-4

x1=-3

plug in the values

[tex]\boxed{\boxed{\bold{y-1=-4(x-(-3)}}}[/tex]

Note:

For Point-Slope Form, we use a point that the line passes through and the slope of the line.

Actually, that's why it's called "Point-Slope Form" right? =)

Hope everything is clear.

Answer:

Step-by-step explanation:

I am not sure why there is no interest rate given as it is common that there will be an interest charge for a monthly installment plan.

Assuming it is an interest-free plan, the remainder payment is for an amount of:

680000*(1 - 12.5%)

= 680000*(0.875)

= 595000 naira

Dividing that into 12 equal monthly, each monthly installment is

595000/12 = 49583.33

~49583 naira

x − 4x + 6y + (14x − 5y) ⇔ 11x+y

(5x − 3y) − x + 3x − 5y ⇔ 7x-8y

5(x + y) + 6(x − y) ⇔ 11x-y
