-12x + 18 – 10x – 5 = -31

Mathematics
2 answers:
storchak [24]3 years ago

Answer:

Your answer is x = 2

Step-by-step explanation: -12x + 18-10x-5 = -31

subtract 18 - 5 = 13 and add -12x+(-10x)= -22x

-22x+13=-31 subtract 13 on both sides

-22x+13(-13)=-31(-13)  cross out +13(-13) and -31-13= -44

-22x=-44 divide -22 on both sides

\frac{-22x}{-22} = \frac{-44}{-22} cross -22x/-22 and divide -44 and -22= 2

x = 2

Andrea bought 12 bagels and 10 muffins at the bakery of these items 2/3of the bagels were Multigrain and3/5of the muffins were b
nevsk [136]
Hi there!

If Andrea bought 12 bagels and 2/3 were multigrain we can determine what the total amount of bagels that are multigrain by finding a common denominator. We can do this by multiplying 2/3 * 4 which gets us the common denominator we need.

2/3 * 4 <--- Equation
8/12 <--- Simplified from step 1.

Therefore 8 out of the 12 bagels Andrea bought were multigrain!

e figure below shows the derivative F' of a function F. If F(20) equals 100, estimate the maximum value attained by by F
Ainat [17]
Max occurs at x=50 where F'(x) = 0.

We need to find value for F(50) using fundamental theorem of calculus:
\int\limits^{50}_{20} {F'(x)} \, dx = F(50) - F(20) = F(50) - 100

F(50) = 100+A
Where A is the estimated Area under the graph.
If we assume the shaded region is close to a right triangle then the Area is (1/2)*30*20 = 300

Therefore
F(50) = 100+300 = 400

What is the solution to the system of equations? {x+y=7x=y+3
abruzzese [7]
<h3>Answer:</h3>

x=5, y=2

<h3>Explanation:</h3>

The second equation gives an expression for x that can be substituted into the first equation.

... (y+3) +y = 7 . . . . . .substitute y+3 for x

... 2y + 3 = 7 . . . . . . . colect terms

... 2y = 4 . . . . . . . . . . subtract 3 from both sides

... y = 2 . . . . . . . . . . . . divide both sides by 2

Using the expression for x, we can find its value.

... x = y + 3

... x = 2 + 3 . . . . . . . . . substitute for y

... x = 5

The solution is (x, y) = (5, 2).
