10. -16 - 7(2a + 3) = 23 - 2a
Answer:
a=-1.5 (lmk if im incorrect)
Step-by-step explanation:
-16 - 7(2a + 3) = 23 - 2a
-16-(14a+21)=23-2a
5-14a=23-2a
5=23+12a
-18=12a
-18/12 is -1.5
a=-1.5
A square has a diagonal that measures 18 inches. To the nearest tenth, what is the length of one side
of the square?
Answer:
18/sqrt(2)
Step-by-step explanation:
Divide the square into two congruent right triangles:
a and b are the sides of the triangle
since we know that a=b
then the right triangle is isosceles
meaning that the theorem of the 45-45-90 triangle is applicable
so then we can say that 18/sqrt(2) = a = b

Why does the government charge high taxes on gasoline?
Answer:
Every time you top off your vehicle at the pump, you're paying federal and state gas taxes that are included in the price of every gallon of gasoline. The federal tax, at 18.4 cents per gallon, is meant to help the federal government pay to build and fix things like highways and bridges.
Step-by-step explanation:
Mark me brainliest
Answer: These taxes are meant to do two things — raise money to pay for infrastructure and reflect some of the environmental costs of driving. Unlike most taxes, gas taxes are charged as a flat charge per liter, rather than as a percentage of the pump price.

A trail runner gets a new map of her favorite mountain. • Her old map has a scale of 1 cm to 100 m. • Her new map has a scale of 1 cm to 500 m. She ran a trail that was 40 cm long on her old map. How long is this trail on her new map?
PLEASE ANSWER
Answer:
The trail on her new map is 8 cm
Step-by-step explanation:
Here, we are interested in knowing the the length of the trail on the new map.
The scale on her old map is 1 cm represents 100 m
While her new map has a scale of 1 cm to 500 m
Now, running a trail of 40 cm on her old map, we need to get the actual distance.
The actual distance will be 40 * 100 = 4,000 m
Now, we shall convert this to the new map scale
We simply convert this to cm in the new map scale by dividing the 4,000 m by 500 m
That would be 4,000/500 = 8 cm
So the trail on her new map is 8 cm
Answer:
The actual distance will be 40 * 100 = 4,000 m
Step-by-step explanation: Now we have to convert the new scale map by dividing the 4,000 m by 500 m so that would be 4,000/500 = 8 cm
which is bigger 7/9 or 5/6
Answer:
5/6
Step-by-step explanation:
7/9 and 5/6 can have the same denominator of 54. Now, you can look only at the numerators, 42 and 45. 45 is greater, so 5/6 is greater than 7/9
5/6 is greater than 7/9
What is a fraction?A common fraction is a numeral which represents a rational number. For example 2/3
Given here, 7/9 and 5/6 now 7/9 = 0.777 and 5/6= 0.833
Thus clearly 5/6 >7/9
Hence, 5/6 is greater than 7/9

what is 1/4 as a negative exponent
Answer:
1/4 = 1/2² = 2^-2
Step-by-step explanation:
1/4 can be expressed as a negative exponent is 4⁻¹
What is the negative exponent rule?A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa. For example, when you see x⁻³, it actually stands for 1/x³
Given here, 1/4 thus it can be expressed as 4⁻¹
Hence, 1/4 can be expressed as a negative exponent is 4⁻¹

y-intercept is -5.
Slope of the line is [tex]\frac{4}{3}[/tex].
What is linear equation?" Linear equation is defined as the algebraic expression whose highest exponent of the variable is 1."
Formula used
Slope = [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
Slope intercept form y=mx +c
c = y-intercept
m = slope
According to the question,
Given linear equation,
[tex]-3y = 15-4x[/tex]

Caitlin is designing a railing for a set of stairs. The railing will begin at a height of 36 inches and follow the slant of the stairs, which decreases 9 inches for every 12 horizontal inches. Which function can represent the height, y, of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs? Y = –StartFraction 3 Over 4 EndFractionx + 36 y = –3x + 36 y = StartFraction 3 Over 4 EndFractionx + 36 y = 3x + 36
Given:
The railing will begin at a height of 36 inches.
Height decreases 9 inches for every 12 horizontal inches.
To find:
The function for this situation.
Solution:
Let y be the height of the railing in inches according to the horizontal distance in inches, x, from the top of the stairs.
Initial height = 36
So, y-intercept is 36.
Height decreases 9 inches for every 12 horizontal inches. So,
[tex]\text{Slope}=\dfrac{\text{Vertical change}}{\text{Horizontal change}}[/tex]
[tex]m=\dfrac{-9}{12}[/tex]
[tex]m=-\dfrac{3}{4}[/tex]
Slope intercept form of a line is
[tex]y=mx+b[/tex]
Substitute [tex]m=-\dfrac{3}{4}[/tex] and b=36.
[tex]y=-\dfrac{3}{4}x+36[/tex]
The required function is [tex]y=-\dfrac{3}{4}x+36[/tex].
Therefore, the correct option is A.
Answer:
A
Step-by-step explanation:

A and B are complementary angles. If mA=(x+8)° and mB =(8x+1),
find the measure of A
Answer:
[tex]\angle A=17\textdegree[/tex]
Step-by-step explanation:
We know that A and B are complementary angles. So, they must add up to 90°. As an equation:
[tex]\angle A+\angle B=90[/tex]
Since we know their equations, substitute:
[tex](x+8)+(8x+1)=90[/tex]
Solve for x. Combine like terms on the left:
[tex]9x+9=90[/tex]
Subtract 9 from both sides:
[tex]9x=81[/tex]
Divide both sides by 9:
[tex]x=9[/tex]
So, the value of x is 9.
We want to find A. So, let's use the equation for A:
[tex]\angle A=x+8[/tex]
Substitute 9 for x:
[tex]\angle A=9+8[/tex]
Add:
[tex]\angle A=17\textdegree[/tex]
So, the measure of A is 17°.
