What is a phrase for the algebraic expression 4+x?

Answer:

9/12 = 4/x

Step-by-step explanation:

The height of the larger triangle is 9. The base of the larger triangle is 12. So let's make the ratio 9/12.

The height of the smaller triangle is 4. The base of the smaller triangle is x. So let's make the ratio 4/x.

Since both triangles are congruent, let's make these both equal each other to solve for x (if you need to).

Thus, it's 9/12 = 4/x.

Answer:

Larger number = 30
Smaller number = 8

Step-by-step explanation:

Let x = larger number

Let y = smaller number

x + y = 38 ————> (1)

x = y + 22 ————> (2)

Substitute for x using first equation

(y + 22) + y = 38

2y + 22 = 38

2y = 16

y = 8

Substitute for y using second equation

x = 8 + 22

x = 30

Step-by-step explanation:

The length and width of the terrace are 15 feet and 6 feet respectively.

The area of the terrace is 90 ft²

The scale of the plan is 2 inches : 6 feet.

Therefore, 2inches represents 6 feet.

According to the drawing;

Therefore,

The area can be found as follows:

where

l = length

w = width

Therefore,

area = 15 × 6 = 90 feet²

Answer:

x = −21.25

Step-by-step explanation:

0.4(-0.2x - 3) = 0.5

distribute the .4

.4 * -0.2 = -0.08x and 0.4 * -3 = −1.2

we now have -0.08x - 1.2 = 0.5

next we add 1.2 to both sides

-0.08x - 1.2 + 1.2 ( these two 1.2's cancel out )  = 0.5 + 1.2 ( 0.5 + 1.2 = 1.7)

we then have -0.08x = 1.7

We then divide both sides by -0.08

-0.08/-0.08 = x

1.7 / -0.08 = −21.25

we're left with x = −21.25

Answer:

x = 34

Step-by-step explanation:

5(x + 7) = 6x + 1

Distributive property

5x + 35 = 6x + 1

Subtract 5x from both sides

35 = x + 1

Subtract 1 from both sides

34 = x

The equation of the circle shown is:

[tex]x^2 + y^2 = 100[/tex]

The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

From the graph, it can be seen that the center of the circle is (0,0), thus [tex](x_0, y_0) = (0,0)[/tex] and the radius is of r = 10, hence the equation is:

[tex]x^2 + y^2 = 100[/tex]

Answer:

3000

Step-by-step explanation:

If they spend 60% of their income, they save 40% of their income

Let x be their income

x * 40 % = 1200

.40x = 1200

Divide each side by .4

x = 1200/.4

x =3000

The value of x is less than or equal to 2.25.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is 47.75 + x ≤ 50.

The value of x.

The expression is 47.75 + x ≤ 50.

On simplifying,

47.75 + x ≤ 50

            x ≤  50 - 47.75

            x ≤ 2.25

Thus, the value of x is less than or equal to 2.25.
