Step-by-step explanation:

3x + 4y =10_____(I)

2x - 2y=2______(II)

Multiple the eqn( II )to 2.

2(2x - 2y =2)

4x - 4y=4_____(III)

Subtracting the eqn (I)to (II)

 3x + 4y=10

 4x - 4y=-4

 7x =14

 x =14/7

 x = 2

put the value of x in eqn (I)

 3(2)+4y=10

Which equation can be used to solve the following word problem? Seth has 8 more nickels than dimes, and the total value of his c

9966 [12]

Answer:

Seth has 21 nickels

Step-by-step explanation:

Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.

Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then

$5n+10(n-8)=235.$

Solve this equation:

$5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.$

The index number representing the price level changes from 109 to 113 in one year. The inflation rate during the year is _____ p

Dima020 [189]

First, get the difference between the price level changes.

$113-109=4$

Then, divide it by the initial price level, which is 109.

$\frac{4}{109}=0.0367$

Multiply by 100 to get its percent.

$0.0367\times100=3.67$

Thefore, the inflation rate during the year is 3.67 percent.

What are the 3 angle measures in the triangle shown below

7nadin3 [17]

9514 1404 393

Answer:

B. 39°, 106°, 43°

Step-by-step explanation:

The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.

(3x +1) +(11x -4) +(5x -7) = 180

19x -10 = 180 . . . . . collect terms

19x = 190 . . . . . . . . add 10

x = 10 . . . . . . . . . . . divide by 19

Then the three angle measures are ...

3·10 +1 = 31
11·10 -4 = 106
5·10 -7 = 43

The appropriate choice is ...

B. 31°, 106°, 43°
