Answer:
The value of 7w - 8 is -22
Step-by-step explanation:
Let us solve the question
∵ -4w - 5 = 3
→ Move -5 from the left side to the right side by adding both sides by 5
∴ -4w - 5 + 5 = 3 + 5
∴ -4w = 8
→ Divide both sides by -4
∵ =
∴ w = -2
→ Now let us find the value of the given expression
∵ The given expression is 7w - 8
→ Substitute w by -2 to gets its value
∴ 7w - 8 = 7(-2) - 8
∴ 7w - 8 = -14 - 8
∴ 7w - 8 = -22
∴ The value of 7w - 8 is -22
Answer:
<em>59</em>
<em></em>
Step-by-step explanation:
If a number is divided by and leaves a remainder
, then the number
will be completely divisible by
.
Therefore, when we say a number , when divided by 6, it leaves a remainder 5, then (
) will be a multiple of 6.
When we say a number , when divided by 5, it leaves a remainder 4, then (
) will be a multiple of 5.
When we say a number , when divided by 4, it leaves a remainder 3, then (
) will be a multiple of 4.
When we say a number , when divided by 3, it leaves a remainder 2, then (
) will be a multiple of 3.
So, is a common multiple of 3, 4, 5 and 6.
Taking LCM of 3, 4, 5 and 6, we get 60.
So, the number 60 - 1 = <em>59</em> is the least such number.
