Answer down below.
Step-by-step explanation:
You can see that the 10 is negative. Now, imagine a number line. If you were to plot that on the number line, its less than 0. Anything in the positives is in the positive number range. If you were to do the same for negatives, it would represent a negative value, or in money standards, would be in debt.

The combined height of one fir tree and one pine tree is 212121 meters. The height of 444 fir trees stacked on top of each other is 242424 meters taller than one pine tree. How tall are the types of trees that Logan genetically engineered?
Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Step-by-step explanation:
Let x= height of each fir tree, y = height of each pine tree.
As per given, we have
x+y = 21 (i)
4x=y+24 (ii)
From (ii),
[tex]4x-y=24[/tex] (iii)
Add (i) and (iii), we get
[tex]5x=45\\\\\Rightarrow\ x=\dfrac{45}{5}\\\\\Rightarrow\ x=9[/tex]
Put value of x in (i), we get
[tex]9+y=21\Rightarrow y=12[/tex]
Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Answer:
Each fir tree is 9 meters tall and each pine tree is 12 meters tall.

How much more would Keri's monthly loan payment be if she got a 5% loan for 5 years?
$
more per month
$9436 EMI Keri has to pay for $500,000 loan at the rate of 5% for 5 years.
What is EMI?equated monthly instalment or EMI relates to payments made regularly to repay an outstanding loan within a certain time frame.
Given loan rate is 5% and time period is 5 years let total amount is $500,000. Formula for EMI Calculation is -
P x R x (1+R)^N / [(1+R)^N-1] where-
P = Principal loan amount.
N = Loan tenure in months.
R = Monthly interest rate.
R = Annual Rate of interest/12/100.
Putting these values in above equation
EMI = 500000 *5* *(1 + 5%)^60 / [(1 + 5%)^60]
EMI = 9436
Therefore, Keri must pay a $9436 EMI on her $500,000 loan over five years at a rate of 5%

The distance from Agnew Middle School to Baylor University is 180 kilometers. There are approximately 8 kilometers in 5 miles. Which measurement is closest to the number of miles between these schools? * 22 mi 113 mi 288 mi 175 mi
Answer:
113 miles
Step-by-step explanation:
Distance = 180 km
Number of km per mile = (8/5) = 1.6 miles
Number of miles between the schools:
Distance / Number of kilometers per mile
180km / 1.6
= 112.5 miles
= 113 miles
Distance between the schools is approximately 113 miles

pls this is a simultaneous equation- one linear one quadratic a-2b =2 -------- (1). a²+b²+2a -3b =19 --------(2). pls I need it urgently thanks
Answer:
Hence a = 3.66 and -3.628
b = 0.834 and -2.634
Step-by-step explanation:
Given the equations
a-2b =2 -------- (1)
a²+b²+2a -3b =19 --------(2).
From 1;
a = 2 + 2b
Substitute into 2
(2+2b)²+b²+2a -3b =19
Expand
4 + 8b + 4b²+b²+2(2+2b)-3b = 19
4b²+b²+8b+4b+4+4-3b = 19
5b²+9b+8 = 19
5b²+9b-11 = 0
b = -9±√81+4(55)/2(5)
b= -9±√301/10
b = -9+17.34/10 and -9-17.34/10
b = 8.34/10 and -26.34/10
b = 0.834 and -2.634
Since a = 2+2b
a = 2+2(0.834)
a= 2 +1.668
a = 3.668
Also
a = 2+2(-2.634)
a = 2 - 5.628
a = -3.628
Hence a = 3.66 and -3.628
b = 0.834 and -2.634
Two siblings ' ages have a sum of 64 years . The older sibling was born 6 years before their young sibling . Write a system of 2 equations . Solve the system using substitution . Report your answer in the form of ( older , younger ).
Answer:
younger sibling = 29 years
older sibling = 35 years
Step-by-step explanation:
Let
x = younger sibling
y = older sibling
x + y = 64 (1)
The older sibling was born 6 years before their young sibling
x = y - 6 (2)
Substitute x = y - 6 into (1)
x + y = 64
y - 6 + y = 64
2y = 64 + 6
2y = 70
y = 70/2
y = 35 years
Substitute y = 35 into (2)
x = y - 6
x = 35 - 6
x = 29 years

Equation: y =
X +
Answer:
y = - 3x - 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (0, - 2) ← 2 points on the line
m = [tex]\frac{-2-4}{0+2}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3
The line crosses the y- axis at (0, - 2 ) ⇒ b = - 2
y = - 3x - 2 ← equation of line

A rectangular window is 3ft long and 2ft wide. Kala would like to buy a screen for the window. The cost of the screen is based on the number of square inches the screen is. Use the facts to find the area of the window in square inches.
Answer:
The cost of screen for window = 864.
Step-by-step explanation:
We have,
A rectangular window of length = 3ft and breadth 2 ft.Fir solving,
As the answers should be in sqaure inches let us first convert ft in inches.Then, we will find the area of window and as the cost of screen is same as that of area,we will find it.★Conversion from ft to inches:
We kow that,
1 foot = 12 inchesTaking this in mind, convert the values
= Length = 3 ft
= Length = 3 × 12
= Length = 36 inchees
= Breadth = 2ft
= Breadth = 2 × 12
= Breadth = 24 inches
★Area of window:
We know that,
= Area of rectangle = Length × Breadth
= Area = 36 × 24
= Area = 864 inches²
As, area of window in square inches equal to cost of the screen.
Therfore, cost of screen would be 864.

A certain brand of shampoo contains 12 ounces in a bottle. The company
decides to redesign the shape of the shampoo bottle. The new type of
bottle contains 15 ounces of shampoo. What is the percent of increase in
the amount of shampoo the new bottle contains?
Answer: 15% I think
Step-by-step explanation:
The percent of increase in the amount of shampoo the new bottle contains is 25%.
Given that, a certain brand of shampoo contains 12 ounces in a bottle and the new type of bottle contains 15 ounces of shampoo.
What is the percentage of increase?Percentage increase is the difference between the final value and the initial value, expressed in the form of a percentage.
Percentage increase = (Final value - Initial value) / Initial value × 100
Now, initial value = 12 and final value = 15
Percentage increase = (15-12)/12 × 100
= 3/12 × 100
= 1/4 × 100
=25%
Therefore, the percent of increase in the amount of shampoo the new bottle contains is 25%.

A small submarine starts at –1,260 feet in relation to sea level. Then it descends 5 feet per minute for 12 minutes.
What expression represents the new position of the submarine in relation to sea level?
Answer:
We know it's at -1260 feet and descends 5 per minute
The expression of this would be: -1260 - 5x, where x would be the time in minutes, as from -1260 feets it descends 5 per min.
Then, if we need to calculate it when it passes 12 minutes, we can replace the x by 12, and get the distance it would be
-1260 -5*12 = -1320 feet
And the answer would be -1320 feets
