Math / Numbers & Operations

QuestionLook at the number line below. What are the two missing numbers?

Studdy Solution

STEP 1

1. The number line is linear, and numbers increase from left to right.
2. The known number on the number line is $1$ .
3. The arrow labeled "+4" indicates a movement of 4 units to the right from the left missing number to reach 1.
4. The arrow labeled "+10" indicates a movement of 10 units to the right from 1 to reach the right missing number.

STEP 2

1. Determine the left missing number.
2. Determine the right missing number.

STEP 3

To find the left missing number, recognize that moving 4 units to the right from this number results in the number 1.

STEP 4

Set up the equation for the left missing number:
Let the left missing number be $x$ . Then:
$x + 4 = 1$

STEP 5

Solve for $x$ by subtracting 4 from both sides:
$x + 4 - 4 = 1 - 4$ $x = -3$

STEP 6

To find the right missing number, recognize that moving 10 units to the right from the number 1 results in this number.

STEP 7

Set up the equation for the right missing number:
Let the right missing number be $y$ . Then:
$1 + 10 = y$

STEP 8

Solve for $y$ by adding 10 to 1:
$y = 1 + 10$ $y = 11$
The two missing numbers on the number line are:
$\boxed{-3 \text{ and } 11}$

STEP 1

STEP 2

1. Determine the left missing number.2. Determine the right missing number.

STEP 3

To find the left missing number, recognize that moving 4 units to the right from this number results in the number 1.

STEP 4

Set up the equation for the left missing number:Let the left missing number be x x x. Then:x+4=1 x + 4 = 1 x+4=1

STEP 5

Solve for x x x by subtracting 4 from both sides:x+4−4=1−4 x + 4 - 4 = 1 - 4 x+4−4=1−4 x=−3 x = -3 x=−3

STEP 6

To find the right missing number, recognize that moving 10 units to the right from the number 1 results in this number.

STEP 7

Set up the equation for the right missing number:Let the right missing number be y y y. Then:1+10=y 1 + 10 = y 1+10=y

STEP 8

Solve for y y y by adding 10 to 1:y=1+10 y = 1 + 10 y=1+10 y=11 y = 11 y=11 The two missing numbers on the number line are:−3 and 11\boxed{-3 \text{ and } 11}−3 and 11​
