16x – 30 - (<span>14x – 6) = 0
16x - 30 - 14x + 6 =0
2x - 24 =0
2x = 24
x = 12</span>

Answer:

f(-7) = 18

Step-by-step explanation:

Add AbS in calculator

Step-by-step explanation:

$\frac{4}{5}$ × 45 = 4 × 9 = 36 ← Marlina's books

Solve for x, y, and z. Enter the integer that is under each radical.

Yuliya22 [10]

Answer:

$x=\sqrt{10}$

$y = \sqrt {14}$

$z = \sqrt {35}$

Step-by-step explanation:

By geometric mean theorem:

$x=\sqrt{2\times 5}$

$x=\sqrt{10}$

By Pythagoras Theorem:

$y^2 = x^2 + 2^2$

$y^2 = (\sqrt{10}) ^2 + 2^2$

$y^2 = 10 + 4$

$y^2 = 14$

$y = \sqrt {14}$

Again by Pythagoras Theorem:

$z^2 = x^2 + 5^2$

$z^2 = (\sqrt{10}) ^2 + 5^2$

$z^2 = 10 + 25$

$z^2 = 35$

$z = \sqrt {35}$

Three fourths of a number is 1/2 find the number in lowest terms

NNADVOKAT [17]

Answer:

To thirds if I'm not wrong

Step-by-step explanation:

three fourths meaning 3/4 of a number is 1/2

so:

3/4 of number is 1/2

1/4 of number = number ÷ 4

3/4 of number = (number ÷ 4) × 3

(number ÷ 4) × 3 = 1/2

number ÷ 4 = 1/6

number = 4/6

number = 2/3

the number is 2/3

The seventh grade class is putting on a variety show to raise money. It cost $700 to rent the

Nataly_w [17]

Well, you would need to compensate for the cost of the banquet hall adding an addition $700 to the goal of $1000.

If you need to raise at least $1700 you can write this inequality.

Let x represent the number of tickets sold.

15x≥1700

x≥ 114 (rounded to the nearest whole number because you can't sell half a ticket)

So, at least 114 tickets need to be sold.
