Answer:
You will have to pay $22.05.
Step-by-step explanation:
We can solve this problem by making a proportion:
4.78 gallons/11 dollars = 9.58 gallons/x dollars
By cross-multiplying, we can solve for x:
4.78x = 105.38
x = 22.05

Make "t" the subject of the formula s=2t+5.
Answer:
t = [tex]\frac{s-5}{2}[/tex]
Step-by-step explanation:
Given
s = 2t + 5 ( subtract 5 from both sides )
s - 5 = 2t ( divide both sides by 2 )
[tex]\frac{s-5}{2}[/tex] = t

HELP!! What is f(x) = 4x + 8 when x = 7
Answer:
Subtract 2 2 from 2 2 . Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x4−2 f - 1 ( x ) = x 4 - 2 is the inverse of f(x)=4x+8 f ( x ) = 4 x + 8 .
Answer:
36
Step-by-step explanation:
4(7) = 28
28+8=36
The measure of an angle is 149°. What is the measure of its supplementary angle?
Answer: 31°
Step-by-step explanation:
Supplementary angles add up to 180 degrees so add 149 degrees to a number of degrees to get 180 degrees.That can be represent by the equation,
149 + x = 180 where x is the supplement so solve for x
-149 -149
x = 31
Represent this statement as an equation: The difference of twice a number and 3 is 11.
Answer:
2x - 3 = 11
Step-by-step explanation:
"difference" means subtraction, so it is subtraction.
"twice a number" simply means 2x, since you do not know what the specified number is, it is x. and the 2 and just making it twice the number.
"Is 11" just means equals 11.
so, 2x - 3 = 11.
hope this helps!
what is greather than -7
what is less than -2
Answer:
The greater than of -7 is 7. The less than -2 is 2.
Step-by-step explanation:
It's the same distance from both but, the positive number always been greater than negative number.
Both questions have an infinite number of correct answers.
Here are six numbers that are greater than -7:
-6.99999, -4, 0, 3, π, 4.00001
Here are six numbers that are less than -2:
-2.00001, -3, -π, -4, -136, -201.358
if the fraction 396/x-10 is equivalent to -22, find the value of x.
Answer: x = -8
Step-by-step explanation:
1. Miltiply x-10 on both sides: 396 = -22(x - 10)
2. Distribute -22 to (x - 10): 396 = -22x + 220
3. Subtract 220 from 396: 176 = -22x
4. Divide both sides by -22 to get x by itself: x = -8
I hope this is helpful :)
Rewrite 4 - 5 using the additive inverse and display the new expression on a number line
When you rewrite subtraction using the additive inverse, you add the opposite. That is, -5 becomes +(-5).
The appropriate choice is ...
... 4 + (−5) A horizontal number line is shown with labels from negative 8 to positive 8. A blue arrow begins at 0 and goes to 4. A red arrow begins at 4 and goes to negative 1.

400 is a rational number because it can be expressed as the quotient of two intergers 400 divided by 1
Step-by-step explanation:
the square root of 400 is rational because the product is 20 which is a whole number making it a rational number because a rational number is any interger, fraction , terminating decimal, or repeating decimal.
16. The quotient of a number and -2 is the same as the sum of -4 and 10.
Answer: The number is -12
Step-by-step explanation:
The situation can be represent by the equation
[tex]\frac{n}{-2} = -4 + 10[/tex] Now solve for n by combining like terms on the right side
[tex]\frac{n}{-2}[/tex] = 6 multiply both sides by -2
n = -12

FACTOR !!!
a) 5x^2+25
b) 2x^2-3x-2
Step-by-step explanation:
(a): 5x^2 + 25 = 5 * x^2 + 5 * 5 = 5(x^2 + 5).
(b): 2x^2 - 3x - 2 = 2x^2 - 4x + x - 2
= 2x(x - 2) + 1(x - 2) = (2x + 1)(x - 2).

Simplify 5(2r+1)-3(-4r+2)
Answer:
22r-1
Step-by-step explanation:
5(2r+1)-3(-4r+2) Distribute the terms
10r+5+12r-6 Combine like terms
22r-1
Answer:
5 ×( 2r +1) - 3 × ( -4r +2)
= 10r +5 +12r -6
= 22r -1
Tanya bought three adult tickets and one children's ticket to a movie for 24.60 Li bought five adult tickets and four children's tickets for 50.10 . Find the cost of one adult ticket and the cost of one children's ticket.
Answer:
adult tickets 6.9
children tickets 3.9
Step-by-step explanation:
3x + y = 24.60 L1
5x + 4y = 50.10 L2
5L1 - 3L2
15x + 5y = 123
-15x - 12y = -150.3
-7y = -27,3
y = -27,3/-7
y = 3.9
3x + y = 24.60
3x + 3.9 = 24.60
3x = 24.60 - 3.9
3x = 20.7
x = 20.7 / 3
x = 6.9

Does anyone know how to do any of these problems? My notes are no help and none of my classmates know what to do either.
Answer:
17) 40°
18) 3x+22
19) (1,-4.5)
20) (-1,-2.5)
Step-by-step explanation:
17) 99=59=40°
18) 2x+7+x+15=3x+22
19) 6-(-8)=14
14/2=7
-8+7=1
-2-(-7)=5
5/2=2.5
-2-2.5=-4.5
midpoint = (1,-4.5)
20) 6-(-8)=14
14/2=7
-8+7=-1
5-(-10)=15
15/2=7.5
-10+7.5=-2.5
Midpoint = (-1,-2.5)
