81 divided by 7 plz just answer it
Answer:
11.57142857 (it doesn't go in evenly)
the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.
When dividing 81 by 7, we can determine how many times 7 can be subtracted from 81 without going into negative values. By repeatedly subtracting 7 from 81, we find that 7 can be subtracted 11 times before reaching 4, which is less than 7. Therefore, the quotient is 11. However, there is a remainder of 4 left over.
So, the result of 81 divided by 7 is 11 with a remainder of 4, which can be expressed as the mixed number 11 4/7 or the improper fraction 81/7.

Are the lines y=-2x-4 and 6x+3y=2 parallel? Answer Yes or No.
Yes, They are parallel
Brainliest?
Answer:
YesStep-by-step explanation:
Given lines:
y=-2x-4 and 6x+3y=2One is given in slope-intercept form, the second one in standard form
Lets bring the second one to slope-intercept form:
6x + 3y = 23y = - 6x + 23y/3 = -6x/3 + 2/3y = -2x + 2/3As we see both of the lines have the slope of -2
Since the slopes are same, the lines are parallel
Find the slope of a line with x-intercept 5 and y-intercept -3.
Answer:
3/5
Step-by-step explanation:
When you are given an x-intercept, the y value will always be 0.
When you are given a y-intercept, the x value will always be 0.
With the intercepts we are given, we can make two points we can solve for the slope with.
(5, 0)
(0, -3)
Now, find the slope with the formula [ y2-y1/x2-x1 ]

HELP ME ASAP IF U CAN!!! a baker needs sugar syrup that is 40% sugar how many gallons of water shoud he add to 5 gallons of 70% sugar syrup to make the 40% syrup. WILL MAKE BRAINLYEST
Answer:
15/4
Step-by-step explanation:
Equation: 40(5+x)=70*5+0x
Solve:
200+40x=350
40x=150
x = 15/4
15/4 gallons is the answer.
3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept.
Let x represent the amount of water in galloons needed to be added to make 40% sugar. Hence:
40% of (x + 5) = 70% of 5
0.4x + 2 = 0.7 * 5
0.4x = 1.5
x = 3.75
Therefore 3.75 gallons of water should he added to 5 gallons of 70% sugar syrup to make the 40% syrup

Move point A to different locations to change the orientation of the parallel lines. (You'll notice that the tool keeps AB and CD parallel to each other) Be sure that points A and B do not cross EF. Do the relationships among the angles that you noted in questions 2 through 4 change if you modify the set of parallel lines this way? Explain.
Answer:
S.A for Edmentum and Plato
Like and Rate
No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
No. For each set of parallel lines, pairs of alternate interior angles are congruent, pairs of alternate exterior angles are congruent, and pairs of same-side interior angles are supplementary. This is the same result as in questions 2 through 4.
How to explain the parallel linesIf we modify the set of parallel lines by moving point A to different locations while ensuring that points A and B do not cross line EF, the relationships among the angles will not change. The statements regarding pairs of alternate interior angles being congruent, pairs of alternate exterior angles being congruent, and pairs of same-side interior angles being supplementary will still hold true.
The reason for this is that the properties of alternate interior angles, alternate exterior angles, and same-side interior angles are dependent on the fact that lines AB and CD are parallel. As long as AB and CD remain parallel, regardless of the position of point A, these angle relationships will remain consistent.

please help...given that elm and oak street are parallel, find m
Answer:
102°
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
m∠A = (3×38 - 12)° = 102°
Answer:
∠a = 3x -12 ( Being corresponding angle)
Now
(3x-12) + (2x + 2) = 180 ( Sum of straight angles)
5x - 10 = 180
5x = 190
x = 38
m∠a = 3x -12 = 3*38 -12 = 102
