Answer:
In the first week, Micah bought 11 gallons of gas.
In the second week, Micah bought 8 gallons of gas.
Step-by-step explanation:
Given:
First week
x gallons of gas at $2.39 per gallon
x gallons = $2.39x
Second week
3 fewer gallons of gas than the first week at $2.49 per gallon
x - 3 gallons = $2.49(x-3)
Total spent = $46.21
$2.39x + $2.49(x-3) = $46.21
2.39x + 2.49x - 7.47 = 46.21
4.88x - 7.47 = 46.21
Add 7.47 to both sides
4.88x - 7.47 + 7.47 = 46.21 + 7.47
4.88x = 53.68
Divide both sides by 4.88
x = 53.68/4.88
= 11
x = 11
First week = x = 11 gallons
Second week
= x - 3
= 11-3
= 8 gallons
Therefore,
In the first week, Micah bought 11 gallons of gas.
In the second week, Micah bought 8 gallons of gas.

Please answer the question from the picture above!!
Answer:
they did the horizontal line test.
Step-by-step explanation:
the vertical line test is to see whether or not a graph is a function. you can draw a vertical line at every x-value to see if there are 2 or more points at that x-value. if there are, then it is not a function. however, this student drew a horizontal line instead. this graph is a function, so the student is incorrect. they did the horizontal line test instead of the vertical line test.

. factorise a^2 -b^2c^2
Hi there.
Glad to see you using Brainly!
Equation:
a^2-b^2c^2
Then, multiply the terms with equal exponents.
(We can do this by multiplying their bases)
After:
a^2 - (b c)^2
Now, using a^2 - b^2 = (a-b)(a+b) we factor.
Therefore, after using that we get:
(a-bc) x (a+bc)
Therefore, our solution is
(a - bc) x (a+bc)
Thanks for using Brainly!

Answer:
[tex] {a}^{2} - {b}^{2} {c}^{2} = (a - bc)(a + bc) [/tex]

A theater has 500 seats. Three fourths of the seats are filled. How many seats are filled?
Answer:
Three fourths of the theater that is 500 seats is 375 seats.
Your answer is 375 seats.
Step-by-step explanation:
Okay, so to find 3/4 of 500 the first thing you want to do is set up an equation. To find 3/4 of 500 you want to multiply 500 by 3/4 so here's your equation.
x= 500*3/4
An equivalent to this is this equation,
x=500/1 *3/4
To solve this multiply the numerators together then the denominators together.
That would give you,
x=1500/4
Simplify by dividing 1500 by 4 and you get 375.
x=375
So that means that three fourths of the theater that is 500 seats is 375 seats.
In the theater, 500 seats fill 3/4, or 375 seats. An algebraic expression is an expression made up of integer constants, variables, and algebraic operations.
What exactly are algebraic expressions?Integer constants, variables, and the basic arithmetic operations of addition, subtraction, multiplication, and division are used to construct algebraic expressions.An algebraic expression would be 5x + 6. x is a variable in this case, whereas 5 and 6 are fixed values. An algebraic expression is a mathematical expression made up of variables, constants, and algebraic operations (addition, subtraction, etc.).A mathematical phrase that includes variables, constants, coefficients, and algebraic operations is known as an algebraic expression. 5x2+6xyc, for example, is an algebraic expression. Algebraic expressions, unlike algebraic equations, do not have equal signs.Given,
500 must be multiplied by 3/4 in order to find 3/4 of 500.
x = 500 × 3/4
This can be compared to this equation
x = 500/1 × 3/4
To find the solution, multiply the numerators and denominators together.
After that, you'd have
x = 1500/4.
By multiplying 1500 by 4, you can get 375 by simplifying.
x = 375
Hence, In other words, 375 seats, or roughly one-quarter of the theater's 500 seats, are available.

Answer:
111°
Explanation:
Based on the F angles theorem, ∠ABH = ∠BFE = 69°,
and based on BE ≅ BF, ∠BEF must also be 69°.
∠DEB is supplementary to ∠BEF, so
∠DEB = 180 - 69 = 111.

Elaine scored 19 out of 24 on her science test.
Addison had 81.25% on the same test.
Who did better?
How do you know?
Answer:
Addison scored a better score on the test.
Step-by-step explanation:
Elaine's score can be found by dividing 19 by 24, which yields a result of 0.7916, which means her score is a 79 out of 100 (79%). Her score can also be found by doing 100/24 = 4.16666 repeating and multiplying that by 19, which also yields 79.6. Hope this helps!

solve 0=12x^2+16x+5 by factoring
Answer: X= -1/2, X= -5/6
Step-by-step explanation:
0=12x^2+16x+5
Move all terms to the left:
0-(12x^2+16x+5)=0
Add all the numbers together, and all the variables
-(12x^2+16x+5)=0
Get rid of parenthesis
-12x^2-16x-5=0
a = -12; b = -16; c = -5;
Δ = b2-4ac
Δ = -162-4·(-12)·(-5)
Δ = 16
The delta value is higher than zero, so the equation has two solutions
Use following formulas to calculate:
x1=−b−Δ√2ax2=−b+Δ√2a
Δ−−√=16−−√=4
-> x1=−b−Δ√2a=−(−16)−42∗−12=12−24=−1/2
-> x2=−b+Δ√2a=−(−16)+42∗−12=20−24=−5/6

solve equation 2(4b-6)=4(3b-7)
Answer:
2(4b - 6) = 4(3b - 7)
This is
8b - 12 = 12b - 28
Now,
16 = 4b
This means that b = 4 :)
Answer:
[tex]\boxed {b = 4}[/tex]
Step-by-step explanation:
Solve for the value of [tex]b[/tex]:
[tex]2(4b - 6) = 4(3b - 7)[/tex]
-Use Distributive Property:
[tex]2(4b - 6) = 4(3b - 7)[/tex]
[tex]8b - 12 = 12b - 28[/tex]
-Take [tex]12b[/tex] and subtract it from [tex]8b[/tex]:
[tex]8b - 12 - 12b = 12b - 12b - 28[/tex]
[tex]-4b - 12 = -28[/tex]
-Add [tex]12[/tex] to both sides:
[tex]-4b - 12 + 12 = -28 + 12[/tex]
[tex]-4b = -16[/tex]
-Divide both sides by [tex]-4[/tex]:
[tex]\frac{-4b}{-4} = \frac{-16}{-4}[/tex]
[tex]\boxed {b = 4}[/tex]
So. therefore, the value of [tex]b[/tex] is [tex]4[/tex].
