What is the solution of the system? Use the elimination method. {4x+2y=182x+3y=15 Enter your answer in the boxes.
Oxana [17]
\left \{ {{4x+2y=18(1)} \atop {2x+3y=15(2)}} \right.
Lets multiply equation (2) by -2 to get:
-4x-6y=-30

Now we can add equations (1) and (2) to eliminate x:
\left \{ {{4x+2y=18}+ \atop {-4x-6y=-30}} \right.
-4y=-12
y= \frac{-12}{-4}
y=3
Now that we know the value of y, we can replace it in equation (1) to get the value of x:
4x+2(3)=18
4x+6=18
4x=12
x= \frac{12}{3}
x=3

We can conclude that both x and y are equal to 3.

Which of the following options have the same value as 2%, percent of 90?
Liula [17]

Answer:

B) 0.02\times 90

E) \frac{2}{100} \times 90

Step-by-step explanation:

Given expression:

2% of 90

Evaluating the expression:

\frac{2}{100} \times 90

⇒ 0.02\times 90

⇒ 1.8

Evaluating each choices given to check if the value matches with the value of given expression.

A) 0.2\times90

⇒ 18

B) 0.02\times 90

⇒ 1.8

C) 200\times 90

⇒ 18000

D) 2\times 90

⇒ 180

E) \frac{2}{100} \times 90

⇒ 0.02\times 90

⇒ 1.8

∴ We see that the value of expressions in options B and E matches with the value of the given expression i.e. 1.8

Independent Practice
baherus [9]

Answer:

C.

f(x) = 0.34 + 0.21(x – 1); $.97

Step-by-step explanation:

In 2002, the price of mailing a letter was $.34 for the first ounce and $.21 for each ounce after the first ounce. Write a rule to describe the function.

---------------------------------------

 

Price = 0.34 + 0.21(x-1) where x is the weight of the item in ounces.

Let +x+ = weight of the letter in ounces

Let +P+ = the price of mailing the letter in dollars

---------------------------------------

+P+=+.34+%2B+.21%2A%28+x+-+1+%29+

( +x+%3E=+1+ )

 

-----------------------------

A 4-ounce letter costs

+P+=+.34+%2B++%28+4+-+1+%29%2A.21+

+P+=+.34+%2B+.63+

+P+=+.97+

It costs $.97
