Answer:

The answer is x = -5.

Step-by-step explanation:

1) Subtract 2x from both sides.

[tex]4x + 9 - 2x = - 1[/tex]

2) Simplify 4x + 9 - 2x to 2x + 9.

[tex]2x + 9 = - 1[/tex]

3) Subtract 9 from both sides.

[tex]2x = - 1 - 9[/tex]

4) Simplify - 1 - 9 to -10.

[tex]2x = - 10[/tex]

5) Divide both sides by 2.

[tex]x = - \frac{10}{2} [/tex]

6) Simplify 10/2 to 5.

[tex]x = - 5[/tex]

Therefor, the answer is x = -5.

Answer:

Step-by-step explanation:

14(2x+4)

14(2(x+2))

28(x+2) or

28x+56

Answer: 28x + 56 or 14(2x) + 14(4). (They are equivalent)

Step-by-step explanation:

Distribute 14 to both 2x and 4.

14(2x+4) = 14(2x) + 14(4)

=28x + 56

Answer:

Step-by-step explanation:

S and L are the number of small cups and large cups, respectively.

S + L = 150

L = 150 - S

1.25S + 2.50L = 265

1.25S + 2.50(150-S) = 265

1.25S - 2.50S + 375 = 265

S = 88

L = 150-S = 62

Answer:

The angle is 50 degrees

Step-by-step explanation:

Sine = Opposite / Hypotenuse

Sine ? = 21 / 33

21 / 33 = 0.6363

Cos-1 of 0.6363 is 50.4788

Round to the nearest degree

50.4788 = 50

sine^- 1 21/33 = θ

Answer: Approximately 0.7 or 70 degrees.

Answer:

14cm

Step-by-step explanation:

All side lengths in a cube will be 7 as the properties of a cube are such that all the side lengths are the same.

Think of the longest line in a cube as a hypotenuse on a triangle.

[tex]7^{2} + 7^{2} = c^{2}[/tex]

49 + 49 = [tex]c^{2}[/tex]

[tex]c^{2}[/tex] = 98

c = [tex]\sqrt{98}[/tex]

[tex](\sqrt{98})^{2} + (\sqrt{98} )^{2}[/tex] = [tex]c^{2}[/tex]

[tex]c^{2}[/tex] = 98 + 98

[tex]c^{2}[/tex] = 196

c = [tex]\sqrt{196}[/tex]

c = 14

The longest line in a cube that has a side length of 7cm is 14cm.

Answer:

0.07t+t

Step-by-step explanation:

The required new expression after increasing the price by 7% is 1.07t, where t is the original price.

The manager of a store increases the price of a popular product by 7%. let t be the original price of the product. The new price is t + 0.07t.
to find an expression equivalent to the new price.

Cost price is the price for the buyer pays to the seller for an object or product.

Here, let the whole proportion of the price of the product is t.
now price increased by 7% so 7/100*t = 0.07*t
The total increase in price  = t + 0.07t
                                    = 1.07 * t
So the new expression for the product after a 7% hike in price, 1.07t

Thus, the required new expression after increasing the price by 7% is 1.07t, where t is the original price.

Answer:

f = (k - 16) / (2k - 16)

k = (16f - 16) / (2f - 1)

Step-by-step explanation:

f(k-8) = 1/2(k-8)-4​

Solve for f:

Divide both sides by (k-8)

f = (k - 16) / (2k - 16)

Solve for k:

Subtract 1/2 * k from both sides.

fk - 8f - (1/2)k = -8

Add 8f to both sides.

fk - 1/2*k = k * (2f - 1)/2 = 8f -8

Divide both sides by (2f - 1)/2

k = (16f - 16) / (2f - 1)

Correct Question:

Explain how you know that 88 is a solution to the equation 1/8x =11 by completing the sentences:

The word "solution" means . . .

88 is a solution to 1/8x=11 because . . .

Answer/Step-by-step explanation:

✔️The word solution means the value of the unknown variable, x. This means, when the value of x is substituted into the equation, the equation becomes balance as the value on the left equals the value on the right.

✔️88 is a solution to ⅛x = 11 because:

if we substitute x for 88 into the equation, both sides would be equal.

Thus:

⅛×88 = 11

11 = 11
