Answer:
a=1
Step-by-step explanation:
To make this easier, combine like terms first.
-5+2a=4a-4-3a
-5+2a=a-4
Then, add 5 on both sides.
-5+2a=a-4
+5 +5
2a=a+1
Now, subtract a on both sides.
2a=a+1
-a -a
a=1

how do i check 8d-25=3d
Answer:
d=5
Step-by-step explanation:
That is the answer if that is what you were looking for.
your welcome
8d-25=3d
8d-3d=25
5d=25
d=5
d=5
8d-25=3d

Jose’s school has 426 students. His principal has promised the Student Council that their idea will be carried out if they can get at least 25% of the student population to sign a petition. So far, 82 students have signed the petition. Jose used the following steps to write an inequality that can be used to determine the number of student signatures still needed:
Step 1. Declare the variable: Let x = the number of student signatures still needed.
Step 2. Create a ratio equivalent to StartFraction total number of signatures needed over total number of students in the school EndFraction : StartFraction x + 82 over 426 EndFraction.
Step 3. Convert 25% to a decimal: 25% = 0.25.
Step 4. Write the inequality: StartFraction x + 82 over 426 EndFraction less-than-or-equal-to 0.25.
What is Jose’s error?
Answer:
D) In Step 4, the inequality should be x+82/426 is at least 0.25
they need 25 more signatures to get their idea carried out

Answer:
Since the given relation is proportional, the value of s multiplied by the constant of proportionality will be the value of P
we can write the above statement as:
s * k = P (where k is the constant of proportionality)
putting some given proportional values of s and P
2 * k = 8
k = 8 / 2
k = 4
Now that we have the constant of proportionality, we can use it in the equation we just made
s * k = P
s (4) = P
4s = P
This is the relationship between s and p, represented by an equation

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
1. What are the side lengths of the scaled copy?
2. Suppose you want to scale the copy back to it's original size. What scale factor should you use?
Answer:
To get the new scaled copy length and width just multiply by seven (2x7 & 3x7)
New length would be 14 because it's "seven times" the original size
New width would be 21
Step-by-step explanation:
1.) 14 and 21
2.) 14 divided by 7 will give you 2
and 21 divided by 7 will give you 3
The answer for question 2 would be to divide your new answers (21 and 14) by the scaled factor of 7.

-3 (4-2x) = 4 - 2x I can't seen to get this one
Let's see what to do buddy...
[tex] - 3(4 - 2x) = 4 - 2x[/tex]
Subtract the sides of the equation minus( 4 - 2x ) :
[tex] - 3(4 - 2x) - (4 - 2x) = 0[/tex]
Factoring ( 4 - 2x ) :
[tex](4 - 2x)( - 3 - 1) = 0[/tex]
[tex](4 - 2x)( - 4) = 0[/tex]
Divided the sides of the equation by -4
[tex]4 - 2x = 0[/tex]
Subtract the sides of the equation minus 4
[tex] - 2x = - 4[/tex]
Negatives simplified.
[tex]2x = 4[/tex]
Divided the sides of the equation by 2

Jose borrowed $1500 from the bank at a rate of 8% simple interest per year. He Paid how much in interest in three years
Answer:
360
Step-by-step explanation:
the answer is $360 because 8% x $1500 = 120 and eventually since it says 3 years we would have to times it by 3 which would equal 360
Jose will $360 in interest in three years.
What is simple interest?Simple interest is based on the principal amount of a loan or the first deposit in a savings account.
Now it is given that,
Principle amount, P = $1500
Rate of interest, R = 8% = 0.08
Time, T = 3 years
Now, since the simple interest paid in T years is given as,
S.I = PRT/100
S.I = 1500*8*3/100
S.I =36000/100
S.I = 360
Simple interest paid in 3 years is $360.
Hence,Jose will $360 in interest in three years.

Please help! I am having an insanely hard time with this
9514 1404 393
Answer:
24.1 units
Step-by-step explanation:
This is done using the Pythagorean theorem (or distance formula) to find the lengths of the sides.
For each side of the figure (except the bottom horizontal), you need to identify the dimensions of the right triangle whose hypotenuse is the side of interest. For example, LM is the hypotenuse of a triangle 4 units high and 1 unit wide. The Pythagorean theorem tells you LM has a length of ...
LM = √(4^2 +1^2) = √17 ≈ 4.12
Similarly ...
KL = √(2^2 +2^2) = √8 ≈ 2.83
JK = √(1^2 +6^2) = √37 ≈ 6.08
NJ = √(5^2 +1^2) = √26 ≈ 5.10
Of course, the length of MN is found by finding the difference of the x-coordinates:
MN = 3 -(-3) = 6
Then the perimeter is the sum of side lengths:
4.12 +2.83 +6.08 +5.10 +6.00 = 23.17 ≈ 24.1 . . . units
If sin(x) = -1/3 and cos(x) > 0, what is tan(2x)?
Answer:

If the value of x is 199.47°. Then the value of tan (2x) will be 0.808.
What is trigonometry?The connection between the lengths and angles of a triangular shape is the subject of trigonometry.
If sin (x) = -1/3
Then the value of x will be
x = sin⁻¹(-1/3)
x = -19.47°, 199.47°, ….
If the value of x is 199.47°. Then the cos x will be positive.
Then the value of tan (2x) will be
tan 2x = tan (2 x 199.47)
tan 2x = tan (398.94)
tan 2x = 0.808
