Answer:
1: 4
Step-by-step explanation:
to find the ratio
12: 48
divide by the both sides, ththus the answer is 1: 4.
Answer: 1.9x2.8 + 3.2+2.8 = 14.28
HOPE THIS HELPS
If x - 7 = -13, we need to get x by itself to solve this equation. To get x by itself, we can add 7 to each side (that way x will be by itself, and only on one side of the equation).
x - 7 + 7 = -13 + 7
We can add 7 to each side without changing the quantity because we do it to BOTH sides.
x = -13 + 7
Since -13 + 7 is -6,
x = -6
Answer:
19/9
Step-by-step explanation:
We are given repeating decimal number 2.1¯.
We know 2.1¯ = 2.1111..... repeating 1's.
Let us assume x is a fraction equals given repating decimal number.
And set it as a first eqaution.
x = 2.1111..... ------------- (equation 1).
Multiplying equation both side by 10 ( because only one digit is repeating after decimal, we multiply by 10).
On multiplying by 10 we get
10*x = 10*2.1111.....
10x = 21.1111...... ----------------- (equation 2)
Subtracting equation 1 from equation 2, we get
10x = 21.1111......
-x = -2.1111.....

9x = 19.
Now, dividing both sides by 9. we get
