Answer:
x = 83
Step-by-step explanation:
You know that half of 3x-9 is x+37. That means 2(x+37) = 3x-9. Solve the left side of the equation. You will get 2x+74. Now the whole equation is 2x+74=3x-9. Well, move the like terms to each of their sides. You will now have 74+9 = 3x-2x. Simplify and you will get 83 = x.
Hope this helps! Please mark me as brainliest!
Answer:
x=83
Step-by-step explanation:
Since we know that half of 3x-9 is x+37, that's the same as saying the double of x+37 or 2(x+37) is equal to 3x-9. So, we can write this equation: 3x-9=2(x+37). Now, all we have to do is use simple algebra to solve the problem:
Steps Justification
3x-9=2(x+37) Original Equation
3x-9=2x+74 Distributive Property of Equality
x-9=74 Subtraction Property of Equality (Subtract 2x from both sides)
x=83 Addition Property of Equality (Add 9 to both sides)
Hope this helps!! :)

Help with #8 please!
Answer:
8. The length of the longest side is 40 ⇒ H
Step-by-step explanation:
8. In the given figure
∵ The triangle has two equal sides 2x + 12 and 5x - 9
→ Equate their expressions to find the value of x
∴ 5x - 9 = 2x + 12
→ Add 9 to both sides
∵ 5x - 9 + 9 = 2x + 12 + 9
∴ 5x = 2x + 21
→ Subtract 2x from both sides
∵ 5x - 2x = 2x - 2x + 21
∴ 3x = 21
→ Divide both sides by 3 to find x
∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{21}{3}[/tex]
∴ x = 7
∵ The longest side is 6x - 2
→ Substitute the value of x in its expression to find its length
∴ The longest side = 6(7) - 2 = 42 - 2
∴ The longest side = 40
∴ The length of the longest side is 40

Which is one characteristic of hurricanes?
occur mostly inland
create widespread damage
last for a short amount of time
gain strength after passing over land
9514 1404 393
Answer:
create widespread damage
Step-by-step explanation:
Hurricanes are tropical storms that generally develop over the Atlantic ocean. The ones of concern in the US are the ones that follow a westward path. They generally gain strength over water, and dissipate over land. They can last several days, though their movement generally means the worst impact in a given area lasts only a matter of hours. (Clean-up may take months or years.)
Hurricanes are one of the largest of storm systems, so can cause widespread damage.

Step-by-step explanation:
[tex] \rm Solve \: for \: b: \\ \rm \longrightarrow A = \dfrac{1}{2} bh \\ \\ \rm A = \dfrac{bh}{2} \: is \: equivalen t \: to \: \dfrac{bh}{2} = A: \\ \rm \longrightarrow \dfrac{bh}{2} = A \\ \\ \rm Divide \: both \: sides \: by \: \dfrac{h}{2} : \\

Answer:
b in terms of A and h will be:
[tex] \boxed{ \rm{b = \frac{2A}{h} }}[/tex]
Step-by-step explanation:
This is basically the formula for finding the area(A) of the triangle in terms of b and h. We have to solve for b in terms of A and h.
[tex] \rm{A = \dfrac{1}{2} bh}[/tex]
Multiplying 2 in the LHS. This is shift because inverse of division is multiplication.
[tex] \rm{2A = bh}[/tex]
Dividing h from both sides,
[tex] \rm{b = \dfrac{2A}{h} }[/tex]

What is the y-value to the solution of y = 5x -4 and y = 2x + 8
Answer:
At the bottom!
Step-by-step explanation:
Put the two equations into the same standard form:
2x-y=8
-5x+2y=3
Now if you add the two equations up, guess what will happen?
You will "eliminate" the y variable, and only be left with the x variable.
Technically, you will get:
2x-y+2+28-5x+29+2y=8+23
-3x+20y=11
-3x=11

A force of 52 N acts upon a 4 kg block sitting on the ground. Calculate the acceleration of the object.
The acceleration of the block is 13 m/sec².
What is Acceleration?Acceleration is defined as the rate of change of velocity with respect to time, It is a vector quantity with units of m/sec².
Force = 52 N
Mass of the block = 4kg
Acceleration =?
The formula for the force applied to any object is given by
F = mass * Acceleration
Substituting the values
52 = 4 * Acceleration
Acceleration = 52 / 4 = 13 m/sec².
Therefore, The acceleration of the block is 13 m/sec².

Answer:
y=3/2x+1/2
Step-by-step explanation:
Answer:
-3x + 2y = 1Step-by-step explanation:
Standard form of linear equation:
Ax + By = CUsing the given points, we find the slope and y-intercept, in slope-intercept form of y = mx + b
m = (-4- 2)/(-3 - 1) = -6/-4 = 3/23/2*1 + b = 2b = 2 - 3/2 = 1/2y = 3/2x + 1/2Converting to standard form

Answer:
The Trout will have to jump 49 cm in order to catch the insect
Step-by-step explanation:
Here, we want to calculate the distance the Trout has to jump in order to catch the Insect
To calculate this, we need to know the difference in the distances
From what we have, the Trout is 32 cm below the surface while the Insect is 17 cm above the surface of the lake
The difference in height which will represent the distance that the Trout has to jump to catch the insect will be ;
17 + 32 = 49 cm

Write the equation of the line that goes through (-3.9, -1.4) and is PERPENDICULAR to 6x + 2y = 9
9514 1404 393
Answer:
10x -30y = 3
Step-by-step explanation:
In general form, you can start by swapping the x- and y-coefficients, negating one of them. To find the new constant for the equation, substitute the values for the given point
2x -6y = 2(-3.9) -6(-1.4)
2x -6y = 0.6
Multiplying by 5 will make the numbers be integers, so will put the equation in standard form.
10x -30y = 3
