4(2.5)^2x = 4
The value of x?
Answer:
x=0
Step-by-step explanation:
If x is 0, then 2x becomes 0. (2.5)^0 would then be 1. 4*1 would give 0 so x=0.

Many counties in Texas missed many school days in the fall of 2017 due to hurricanes
that year. A solution for how to make up those
days was to add time to each school day
for a portion of the year. It was decided that in order to make up a 6 hour school day, 10
minutes would be added to each day. How many extended days would be needed to
make up 3 school days?

Answer: 70
90+20=110
180-110=70
I hope this is good enough:
Answer:
70
Step-by-step explanation:
Everything needs to add up to 180. So you have 90 and 20 you will add them and you’ll get 110. Since you want to find the missing measurement you will subtract 180-110 and you’ll get 70. The missing angle is 70. To check: 90+20+70=180

On Monday, the temperature was 43°F. On Tuesday, the temperature increased 6°F. On Wednesday, the temperature decreased 13°F. Which integer represents the overall change in temperature from Monday to Wednesday?
Answer:c Thursday
Step-by-step explanation:
If on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F the overall change in temperature from Monday to Wednesday will be 24°F.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.
It is given that on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F. On Wednesday, the temperature decreased by 13°F.
The overall change in temperature from Monday to Wednesday is found as,
= 43°F + 6°F - 13°F
= 24 °F
Thus, if on Monday, the temperature was 43°F. On Tuesday, the temperature increased by 6°F the overall change in temperature from Monday to Wednesday will be 24°F.

The equation of the line in slope Intercept form is
Answer:
y = 60x + 40
Step-by-step explanation:
It is in the form of
y = mx + b
m is the slope
b is the y intercept.
The y intercept is 40, so it will be y = mx + 40.
The slope is 60, so y = 60x + 40!

Can someone put this into vertex form?
y=x2+24x-15
Answer:
The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159
Step-by-step explanation:
The vertex form of the quadratic equation y = ax² + bx + c is
y = a(x - h)² + k, where
a is the coefficient of x²(h, k) are the coordinates of the vertex pointh = [tex]\frac{-b}{2a}[/tex] , where b is the coefficient of xk = y at x = hLet us use the facts above to solve the question
∵ y = x² + 24x - 15
∵ a is the coefficient of x² and b is the coefficient of x
∴ a = 1 and b = 24
∵ h is the x-coordinate of the vertex point
∵ h = [tex]\frac{-b}{2a}[/tex]
→ Substitute the values of a and b to find h
∴ h = [tex]\frac{-24}{2(1)}=\frac{-24}{2}[/tex]
∴ h = -12
→ To find k substitute y by k and x by h
∵ y = k and x = h
∴ k = (-12)² + 24(-12) - 15 = 144 - 288 - 15
∴ k = -159
∴ The coordinates of the vertex point are (-12, -159)
→ Substitute the values of a, h, and k in the vertex form above
∵ y = 1(x - -12)² + (-159)
→ Remember (-)(-) = (+) and (+)(-) = (-)
∴ y = (x + 12)² - 159
∴ The vertex form of y = x² + 24x - 15 is y = (x + 12)² - 159

4. John is packing books into boxes. Each box can hold either 15 small books or 8
large books. He needs to pack at least 35 boxes and at least 350 books, Write a
system of linear inequalities to represent the situation
Answer:
Your system of inequalities is:
x + y ≥ 35
15x + 8y ≥ 350
Step-by-step explanation:
Let x = number of boxes of small books and let y = number of boxes of large books.
Since John needs to pack at least 35 boxes:
(number of boxes of small books) + (number of boxes of large books) (is at least) 35
x + y ≥ 35
Since John needs to pack at least 350 books:
(number of small books packed) + (number of large books packed) (is at least) 350
(number of small books per box)(number of boxes of small books) + (number of large books per box)(number of boxes of small books) ≥ 350
15x + 8y ≥ 350
The price of a dress was reduce from $20 to $12. By what percentage was the price of the dress reduced?
Answer:
40%
Step-by-step explanation:
12$ out of the original 20$ = 12/20
12/20 = .6 (60%)
1=100%
if 12/20 = 60% then 100% - 60% = 40%
$20-40% is $12

The ratio of Braydon's number of laps he ran to the time he ran is 6:2. The ratio of Monique's number of laps she ran to the time she ran is 104. Explain why these ratios are not in a proportional relationship.
Answer:
They are not in a proportional relationship because Monique's number and time isnt a proportion. Instead it is a whole number. Like Braydon's his is 6:2 that is the correct way to write it.
Step-by-step explanation:
The ratio is not proportion.
What is ratio and proportion?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given:
The ratio of Braydon's number of laps he ran to the time he ran is 6:2.
The ratio of Monique's number of laps she ran to the time she ran is 10:4.
The simplest for Braydon is = 6/2 = 3/1
and, the simplest form for Monique = 10/4 = 5/2
As, 3/1 ≠ 5/2
So, the ratio is not proportion.

The property tax on a $60,000 home is $1,500. At this rate what will the property tax be on a home worth $75,000?
Answer:
The answer is $1,875
Step-by-step explanation:
1. I just divided $60,000 by 2 and $1,500 by 2 and got $30,000:$750
2. I realized I needed to do more so I divided again and got $15,000:$375. Next I added it to the question $60,000 + $15,000 = $75,000
3. So then $1,500 + $375 = $1,875
4. $75,000:$1,875
