Which number sentence shows the correct placement of the decimal point in the product, based on the two factors? (3 points) 2.52 × 27.94 = 704.088
94.1 × 2.5 = 23.525
1.83 × 2.9 = 53.07
25.07 × 5.4 = 135.378

25.07 × 5.4 = 135.378

Step-by-step explanation:

In placement of the decimal point in multiplication , first check the numbers that will multiply and count the individual decimal points in the numbers.

In this case,

25.07 × 5.4 = 2 * 1 decimal place

The answer should have  2+1 = 3 decimal placesnote the addition sign

25.07 × 5.4 = 135.378 the answer has 3 decimal places

The first answer is incorrect because ;

2.52 × 27.94 = 704.088 2 *2 = 4 , but the answer has 3

The second answer is incorrect because;

94.1 × 2.5 = 23.525 1 * 1= 2 decimal places, the answer has 3

The third answer is incorrect because ;

1.83 × 2.9 = 53.072*1= 3 decimal places , the answer has 2

neither i nor ii 56 / 4.9 = 11.91489362 and 82 / (11+5) =5.125 so i is wrong

ii. (24/8+2) times 3 = 15 and (42+9)/2 =25.5

step-by-step explanation:

56

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
