Answer:
11:00
Step-by-step explanation:
This is easier than I thought...
So 8:30+2 is 10:30
...and now we have 1/2 left.
1/2 in this case of time would be 30
So, 10+30+30 would be 10:60
Now all we have to do is simplify it
60 minutes= 1 hour
So...
10:60-60=10
10+1=11
11 AM is the correct answer!
Hope this helps! :D

= 2x² + 3x + x² - 4x -3x + 12
= 3x² -4x + 12
I didn't pay attention in class for a few days and now I'm lost. if somebody could at least explain proportions I would be very thankful.
Answer:
A proportion is a comparison of two numbers that each represent the parts of a whole. Essentially, a proportion says that two fractions are the same, even if the amount is different. For example, 1/2 of 10 marbles is the same proportion as 1/2 of 50 marbles.

Answer:
184
Step-by-step explanation:
SA = 2LW + 2LH + 2WH
SA = 2(5 × 4) + 2(5 × 8) + 2(4 × 8)
SA = 2(20) + 2(40) + 2(32)
SA = 40 + 80 + 64
SA = 184

1. Solve the simultaneous equations 3x - 2y = 4and 2x + 3y = -6 using elimination method.
Answer:
Multiply the first equation by 2
2(2x+y=5) to get 4x + 2y = 10
add the second equation 3x-2y=4
4x + 3x + 2y + -2y = 10 + 4
7x = 14
x = 2
...
Multiply the first equation by 3 and the second equation by -2 then add
3(2x+y=5) to get 6x + 3y = 15
-2(3x-2y=4) to get -6x + 4y = -8
add them
6x + -6x + 3y + 4y = 15 + -8
7y = 7
y = 1
...
x = 2 , y = 1
(2, 1) is the solution
...
check
2(2) + 1 = 5
4 + 1 = 5
5 = 5
Correct

A construction company can remove 3/3/4 metric tons of dirt from a construction site in 1/1/8 hours what is the unit rate in metric tons per hour write your answer as a fraction or a mixed number in simplest form
Answer:
3 1/3 metric tons per hour
Step-by-step explanation:
To find the unit rate, divide 3 3/4 metric tons by 1 1/8 hours (notice that the correct format is 3 3/4, not 3/3/4).
3 3/4 metric tons 3.75 metric tons
---------------------------- = --------------------------
1 1/8 hours 1.125 hours
It's easier to deal with decimal fractions here than with proper fractions.
The unit rate then comes out to be 3.75/1.125 metric tons per hour, or
3.33333 metric tons per hour, or 3 1/3 metric tons per hour

Tell whether the angles are adjacent or vertical. Then find the value of x.
to
128°
The angles are
vertical
X=
Answer:
x = 128
Step-by-step explanation:
Adjacent angles - Angles right next to each other. They share a common vertex
Vertical angles - angles that are vertically aligned with each other.
The angle that has a measure of 128 degrees and x are vertical angles
If you didn't know vertical angles are congruent so because one angle equals 128 degrees the other equals 128 degrees
x = 128
The given angle are the vertical angles and the measure of the angle x is 128°.
Given that,
To specify whether the angles are adjacent or vertical. Then find the value of x.
orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
By the observation, angle x and 128° are the vertical angles and by the property of the intersection of the line both are equal angles so the measure of angle x is also equal to 128°.
Thus, the given angle is the vertical angle and the measure of the angle x is 128°.

Gabriel wants to solve the equation 5 eights M equals 25 what steps should he do to get him by itself on one side of the equation
Answer:
Kindly check explanation
Step-by-step explanation:
Given the Equation :
(5/8)m = 25
The first step to take with this kind of equation is to multiply both sides by the denominator, 8
5m/8 * 8 = 25 *8
5m = 200
Then, we can divide both sides by 5 in other to isolate m
5m / 5 = 200 / 5
m = 40
Answer: m+40
Step-by-step explanation:
Given the Equation :
(5/8)m = 25
The first step to take with this kind of equation is to multiply both sides by the denominator, 8
5m/8 * 8 = 25 *8
5m = 200
Then, we can divide both sides by 5 in other to isolate m

5 points A farmhouse shelters 10 animals. Some are goats and some are ducks. Altogether there are 36 legs. How many ducks and goats are there?
Answer:
2 ducks and 8 goats
Step-by-step explanation:
let goat be g
let duck be d
d + g = 10
ducks have 2 legs, 2d
goats have 4 legs, 4g
2d + 4g = 36
making d the subject in the first equation;
d = 10 - g
put in second equation
2(10 - g) + 4g = 36
20 -2g + 4g = 36
2g = 36 - 20
2g = 16
g = 8
if g is 8
d = 10 - 8
d = 2

Answer:
Adding 12 to the circle area is equal to the square area.
Or
s2 = 12 + A
Where
s = side of square
A = area of circle
So
s2 = 12 + 36
s2 = 48
Solve this for s to get the side length
