9a-ab+5b
if a=2 and b=7
Answer:
39
Step-by-step explanation:
9a=18 ab=14 5b=35
18-14+35=39
Answer:
39
Step-by-step explanation:
9a-ab+5b
a=2 and b=7
we substitute the variables with their real numbers
9(2)-(2 x 7)+5(7)
from here we just simplify the equation
18-14+35=39
which of the following us the solution to | x | +5 < 1
the picture is the choices
Answer:
No solution
Step-by-step explanation:
The lines mean absolute value so any negative number will become positive, meaning once simplified you will have a positive number added to five and there is no positive number that when added to five will be less than 1.

4x-7=7x-61 solve for x
Answer:
x = 18Step-by-step explanation:
4x - 7 = 7x - 61
Subtract 7x from both sides
That's
4x - 7x - 7 = 7x - 7x - 61
- 3x - 7 = - 61
Add 7 to both sides
We have
- 3x + 7 - 7 = - 61 + 7
- 3x = - 54
Divide both sides by - 3
That's
[tex] \frac{ - 3x}{ - 3} = \frac{ - 54}{ - 3} [/tex]We have the final answer as
x = 18Hope this helps you
Answer: 18
Step-by-step explanation:
4x - 7 = 7x - 61
+61 +61
4x + 54 = 7x
divide both sides by 4
x + 27/2 = 7/4x
-x -x
27/2 = 3/4x
divide both sides by 3/4
x = 18
A rectangular hotel room is 4 yards by 5 yards. The owner of the hotel wants to recarpet the room with carpet that costs $51.92 per square yard. How much will it cost to recarpet the room?
Answer:
it will cost him $2204 to recarpet the room.
Step-by-step explanation:
The floor of the room is rectangular. The formula for determining the area of a rectangle is expressed as
Area = length × width
The rectangular hotel room is 4 yards by 7 yards. It means that the area of the rectangular floor would be
Area = 4 × 7 = 28 square yard.
If the cost of the carpet $58.00 per square yard, the total that it will cost to recarpet the room would be
38 × 58.00 = $2204

Greetings from Brasil...
For the composite function F(G(X)), just replace the function G(X) in the X of F(X):
F(X) = X² - 2X - 3
G(X) = 5X²
F(G(X)) = [G(X)]² - 2 · [G(X)] - 3
F(G(X)) = [5X²]² - 2 · [5X²] - 3
F(G(X)) = 25X⁴ - 10X² - 3PLZ HURRY IT'S URGENT!!
The sum of a number and six is seven times the number.
Which is a translation of the sentence into an equation?
n + 6 = 7n
n − 6 = 7n
7(n + 6) = n
n = 7n + 6
Answer:
n + 6 = 7n
Step-by-step explanation:
"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.
n − 6 = 7n is not right because the statement says the sum of a number and six.
7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.
n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.
