Answer:
15
Step-by-step explanation:
the expression is (x+y)+5
Now, you need to plug in x=6 and y=4.
So, you have the expression, (6+4)+5
You then add the 6 and 4 since they are in parenthesis, which equals 10. Then you add the 5, which equals 15.
Solve the system of equation by elimination.

solve the solution of the equations 10x-3y=3 and 2x+y=9
Answer:
x=1.875 y=-0.875
Step-by-step explanation:
10x-3y=3 10x-3y=3
3(2x+y)=(9)3 +6x+3y=27
1/16(16x)=(30)1/16 = x=1.875
10x-3y=3 10x-3y=3
-5(2x+y)=(9)-5 -10x-5y=4
1/-8(-8y)=(7)1/-8 = y=-0.875
Melissa runs 7 miles in 50 minutes. At the same rate, how many miles would she run in 75 minutes?
Marisol is being paid $792 to provide nutrition counseling, It took her 8 hours more than she expected, so
she earned $4 per hour less than she originally calculated. How long had she anticipated it would take to do
the job?
Answer: 44 hours.
Step-by-step explanation:
Marisol is being paid $792.
We know that the job took her 8 hours more than she expected, so if we define T as the time she expected, this job took her:
T + 8 hours.
The amount of money per hour that she expected is calculated as:
$792/T = X
And for those 8 extra hours, she won $4 less per hour, then we have:
$792/(T + 8hs) = X - $4
Then we have a system of equations:
$792/T = X
$792/(T + 8hs) = X - $4
To solve this, we can notice that in the first equation X is isolated, then we could replace that in the second equation to get:
$792/(T + 8hs) = $792/T - $4
Now we can solve this for T.
$792 = ($792/T - $4)*(T + 8hs) = $792 + $792*(8hs/T) - $4*T + $32*hs
0 = $792*(8hs/T) - $4*T + $32*hs
Let´s multiply this both sides by T
0*T = ($792*(8hs/T) - $4*T + $32*hs)*T
0 = $792*8hs - $4*T^2 +$32*T*hs
This is a quadratic equation, where i will write this witout units so it is easier to read and follow:
0 = -4*T^2 + 32*T + 792*8
The solutions cab be found by using the Bhaskara´s formula, these are:
[tex]T = \frac{-32 +- \sqrt[2]{(32^2 - 4*(-4)*(792*8)} }{2*-4} = \frac{-32 +-320}{-8}[/tex]
Then the solutions are:
T = (-32 + 320)/-8 = -36 hours (This is a negative time, and it does not really have a meaning in this problem, so we can discard this option)
The other solution is:
T = (-32 - 320)/-8 = 44 hours.
Then we can conclude that she expected the job would take 44 hours in total.

The value 9 is 200% of what number?
Answer:
18
Step-by-step explanation:
If 100% is 9 then you need to multiply by 2 to get 200% which is 18.
Answer:
4.5
Step-by-step explanation:
To get from 200% to 100%, you have to divide by 2, so then do the same thing to 9.
9 divided by 2 is 4.5

Let f(x)
40e^.06t. What is the average rate of change of f over the
interval [0,3]? Give your answer as a decimal with one place of
accuracy to the right of the decimal point.
Answer:
[tex]R= 2.6[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 40e^{.06t[/tex]
[tex][a,b] = [0,3][/tex]
Required
Determine the average rate of change (R)
This is calculated as follows:
[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]
Where
[tex]a = 0[/tex] and [tex]b = 3[/tex]
Substitute 0 for a and 3 for b
[tex]R = \frac{f(3) - f(0)}{3 - 0}[/tex]
[tex]R = \frac{f(3) - f(0)}{3}[/tex]
[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]
Calculate f(3)
[tex]f(x) = 40e^{.06t[/tex]
[tex]f(3) = 40e^{.06*3}[/tex]
[tex]f(3) = 40e^{0.18}[/tex]
[tex]f(3) = 40 * 1.197[/tex]
[tex]f(3) = 47.88[/tex]
Calculate f(0)
[tex]f(x) = 40e^{.06t[/tex]
[tex]f(0) = 40e^{.06*0}[/tex]
[tex]f(0) = 40e^{0}[/tex]
[tex]f(0) = 40*1[/tex]
[tex]f(0) = 40[/tex]
So, the expression:
[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]
[tex]R= \frac{1}{3}[47.88 - 40][/tex]
[tex]R= \frac{1}{3}[7.88][/tex]
[tex]R= 2.62666666667[/tex]
[tex]R= 2.6[/tex]
Hence, the average rate of change is approximately 2.6

Answer:
Perimeter = 8x
Step-by-step explanation:
If I can see correctly, the area of the squares are x². Area is just s², so we can find one side by finding the square root of x², which is x. Now that we know that x is one side, we can count the amount of sides and multiply that number by x.
There are 8 sides, so the answer is P = 8x
Karen finished watching a movie at 1:10pm. The movie lasted 1 hour 38 minutes. Click on the time Karen started watching the movie.
Answer:
11:32
Step-by-step explanation:
Karen probably started watching the movie at 11:32 because 11:32 + 1:38 = 1:10.
32+ 38= 70, so 11:00 + 70 = 12:10, plus 1 hour = 1:10.

b. no
Yes. Given figure tessellates the plane.
What is tessellation?"It is a pattern created with identical shapes which fit together with no gaps."
For given situation,
The figure is a hexagon.
A shape is said to tessellate the plane if the plane can be covered without holes and no overlapping (save for the boundary points) with congruent copies of the shape.

A recipe calls for 2/3 cups of sugar per batch. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?
Answer:
8
Step-by-step explanation:
In order you find the answer, you must divide 5 1/3 by 2/3.
In order to do this, you have to convert 5 1/3 into an irregular fraction, by multiplying 5 by 3 and adding it to 1. You'll end up with 16/3
When dividing fractions, you multiply the first number by the reciprocal of the second. 16/3 is the number being divided, so 2/3 will be our second number. The reciprocal of 2/3 is 3/2.
16/3 x 3/2 = 8.
