Answer:
x = 5 (see below)
Step-by-step explanation:
Combine like terms by subtracting on both sides:
25 + 8x = 5 + 12x
20 = 4x
Then divide:
20 = 4x
5 = x
Move the variable to the left side of the equation:
x = 5

Answer:
Wait like all of them or some? I think it's 3 and 4.
Step-by-step explanation:
You add the two negative (negative + negative =positive). 3 and 4 have an extra left over which makes one negative, unless I did that wrong
Answer: 3 and 4
Step-by-step explanation:
If it is an odd number of (-1)s then it is negative. if it is an even number of them then it is positive.
A division problem has 43 as its divisor. The partial quotient are 20 and 7. The remainder is 19. What is the dividend?
A division problem has 43 as its divisor. Then the value of the dividend will be 1,180.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The formula is given as,
Dividend = Quotient × Divisor + Remainder
A division issue has 43 as its divisor. The halfway remainder are 20 and 7. The rest of 19.
Dividend = (20 + 7) × 43 + 19
Dividend = 27 × 43 + 19
Dividend = 1,161 + 19
Dividend = 1,180

3(r+2)+5(2-r) =-32 can someone tell em the answer to that please
Answer:
r = 24
Step-by-step explanation:
3(r+2)+5(2−r)=−32
Step 1: Simplify both sides of the equation.
3(r+2)+5(2−r)=−32
(3)(r)+(3)(2)+(5)(2)+(5)(−r)=−32(Distribute)
3r+6+10+−5r=−32
(3r+−5r)+(6+10)=−32(Combine Like Terms)
−2r+16=−32
−2r+16=−32
Step 2: Subtract 16 from both sides.
−2r+16−16=−32−16
−2r=−48
Step 3: Divide both sides by -2.
−2r/-2 = -48/-2
r = 24
Answer: r = 24
3(r+2)+5(2-r) =-32
this equals (if we do the multiplication)
3r+6+10-5r=-32
this equals (if we simplify)
-2r+16=-32
this equals (because we are subtracting from 1 side, we must subtract from the other)
-2r=-48
r=24
A bag contains 37 coins consisting of only dimes and quarters.The total amount of money in the bag is $6.85. How many dimes are in the bag ??
Answer:
16 dimes
Step-by-step explanation:
D=number of dimes
Q=number of quarters
D+Q=37
.25 xQ + .10 x D=6.85
sub Q from first equation
.25(37-D) + .10 x D=6.85
D(.10-.25) + .25 x 37 =6.85
-.15D + 9.25=6.85
D= (6.85-9.25)/(-.15)
D=16

PLEASE HELP, find the orthocenter of this triangle
Answer:
The orthocenter of a triangle is the point at which the three altitudes of a triangle intersect. This involves creating 3 lines, one from each vertex (K, L, and M) perpendicular to the line segment opposite it, so K⊥LM, L⊥KM, and M⊥KL.
Because these three lines intersect at one point, you only need to do this procedure for two of the three altitudes. Because K and M are on the same Y coordinate (-4), lets do this for LM and KL
First, we need to find the slope of the perpendicular to each line segment, so we need the slope of LM and KL.
The slope is the change in Y over the change in X
Slope LM = 6 -(-4) / 2-7 = 10/-5 = -2
Slope KL = -4-(6) / 4-2 = -10/2 = -5
The slope of a perpendicular line is the negative reciprocal of the slope of the given line, so for
the slope of K⊥LM has to be 1/2 and
the slope of M⊥KL has to be 1/5
Second, the vertex has to be on a line with that slope. So using the point-slope formula
(y-y1) = m(x-x1) , where x1,y1 is a point on the line for each line gives us
K⊥LM: y-(-4) = 1/2(x-4)
M⊥KL: y-(-4) = 1/5(x-7)
Third, find the point on both lines, are where the two equations are equal
So, 1/2(x)-2 = 1/5(x) - 7/5;
5x - 20 = 2x - 14
3x = 6 --> x=2
y+4=-1 --> y=-5

Determine the domain on which the following function is increasing. Will give brainlist if correct
Answer: D : x ∈ (1, ∞)
Step-by-step explanation:
for a function y = f(x)
The range is the set of possible values of y.
The domain is the set of the possible values of x.
We want to find the domain on which the function is increasing.
A function is increasing if, reading from left to right, the "y" value of the function increases (or the graph goes upward)
Then we need to see on which point the graph starts going up. We can see that this happens at the vertex of the parabola, at x = 1, and it keeps increasing infinitely.
then we can write this domain as:
D : x ∈ (1, ∞)
