1 answer:

6 0

Let the number be x,
The sum of the number and 8 is
$(x + 8)$
The square of the difference of the number and 4 is
$(x - 4) {}^{2}$

Hence the inequality is
$(x + 8) \leqslant (x - 4) {}^{2}$

The correct answer is C

Find L when P= 24 and W = 6. P = 2L+ 2W (perimeter of a rectangle) L =

Anon25 [30]

Answer:

Step-by-step explanation:

24 = 2L + 2(6), multiply...

24 = 2L + 12, subtract 12 to both sides...

12 = 2L, divide 2 to both sides to isolate the varibale L

6 = L

Therefroe, L = 6

aksik [14]

Answer:

15 liters

Step-by-step explanation:

Given:

We need 5 liters of Yoda soda for 12 guest.

To find:

If we have 36 guest how many liters of Yoda soda we need.

Solution:

By unitary method:

For 12 guests, we need liters of Yoda soda = 5

For 1 guest, we need liters of Yoda soda = $\frac{5}{12}$

For 36 guests, we need liters of Yoda soda = $\frac{5}{12}\times36=\frac{180}{12} =15\ liters$

Therefore, we need 15 liters of Yoda soda for 36 guests.

The table can be used to determine the solution to the system of equations, 2y − x = 8, and y − 2x = −5. Which solution can be u

SIZIF [17.4K]

The answer is (6, 7)

This is the system of two equations:
2y − x = 8
y − 2x = −5
_____
Express the second equation in the term of y:
2y - x = 8
y = 2x - 5
_____
Substitute y in the first equation:
2(2x - 5) - x = 8
4x - 10 - x = 8
4x - x = 10 + 8
3x = 18
x = 18/3
x = 6

Since x = 6 and y = 2x - 5, then:
y = 2 * 6 - 5
y = 12 - 5
y = 7

Therefore, (x, y) = (6, 7)
