Step-by-step explanation:
Let's solve your equation step-by-step.
7√x−4−6=15
Step 1: Add 6 to both sides.
7√x−4−6+6=15+6
7√x−4=21
Step 2: Divide both sides by 7.
7√x−4
7
=
21
7
√x−4=3
Step 3: Solve Square Root.
√x−4=3
x−4=32(Square both sides)
x−4=9
x−4+4=9+4(Add 4 to both sides)
x=13
Answer:
x = 13
Step-by-step explanation:
[tex]7 \sqrt{x - 4} = 15 + 6 \\ 7 \sqrt{x - 4} = 21 \\ \sqrt{x - 4 =} = 3 \\ x - 4 = 9 \\ x = 13[/tex]

Robert is baking desserts for a picnic. He needs to make at least 20 servings of dessert for the
event. For every batch of brownies he bakes, he will get 8 servings, and every pie will
yield 14 servings.
Answers
Answer:
x*8 + y*14 ≥ 20
Step-by-step explanation:
We know that:
A batch of brownies makes 8 servings.
A pie makes 14 servings.
He wants to make, at least, 20 servings.
Then if he makes x batches of brownies, he will get x times 8 servings.
If he makes y pies, he will get y times 14 servings.
Adding that, he will get a total of:
x*8 + y*14 servings
And because he wants to make at least 20 servings (he can make 20 or more)
The inequality will be:
x*8 + y*14 ≥ 20
Where the "≥" symbol means that the expression at the left is greater than or equal to the expression of the right

If median are getting from " ( a + b ) ÷ 2 " . So :
.
Find b :
.
(a + b) ÷ 2 = Median
(17 + b) ÷ 2 = 18
17 + b = 18 × 2
17 + b = 36
b = 36 - 17
b = 19
.
In conclusion, the value of b is 19
.
Find a :
[tex] \frac{7 + a + 12 + 15 + 17 + 19 + 20 + 22 + 24 + 25}{10} = 17[/tex]
[tex] \frac{161 + a}{10} = 17 \\ [/tex]
[tex]161 + a = 17 \times 10[/tex]
[tex]161 + a = 170[/tex]
[tex]a = 170 - 161[/tex]
[tex]a = 9[/tex]
.
In conclusion, the value of a is 9

Step-by-step explanation:

x² - 8x + 3x - 24 = 0
(x² - 8x) + (3x - 24) = 0

(x + 3)(x - 8) = 0
x + 3 = 0, x = -3
