What is the answer to 1 2/3÷10+5​
ratelena [41]

Answer:

The answer is 5 1/6

Step-by-step explanation:

1 2/3 ÷ 10 + 5

5/3 ÷ 10/1 + 5/1

From the rule of BODMAS, we solve for division before subtraction

to change division to multiplication, 10/1 will become 1/10, then will we have

5/3 × 1/10 +  5/1

1/3 ×1/2 + 5/1

1/6 + 5/1

The common multiple of 6 and 1 is 6, so if we solve for the fraction, we will have

1/6 + 30/6 = 31/6

= 5 1/6

Question 3(Multiple Choice Worth 4 points)
boyakko [2]

Answer:

The correct option is (1).

Step-by-step explanation:

The given system of equation is,

y=-x+4       ..... (1)

y=3x+3      .... (2)

The solution of the system of equation is the point where both line intersect each other.

Solve the equation by method of elimination.

Multiply equation 1 by 3.

3y=-3x+12    ... (3)

Add equation (2) and (3).

y+3y=3x+3+(-3x+12)

4y=3x+3-3x+12

4y=15

y=3.75

Put this value in equation 1.

3.75=-x+4

x=-3.75+4

x=0.25

Therefore, the lines intersect each other at (0.25,3.75). So, the first option is correct.
