Find the number when the product of 7 and a number is increased by 7 and the result is 12?
7n + 7 = 12Subtract 7 from each side of the equation :7n = 5Divide each side by 7 :n = 5/7
3 times the sum of a number and 2 is 12?
This can be expressed as: 3(x+2) = 12so, divide both sides by 3(x+2) = 4subtract 2 from both sidesx = 2
Nine plus the quotient of a number b and ten is greater than or equal to eleven?
9 + b/10 >= 11Subtract 9 from each side :b/10 >= 2Multiply each side by 10 :b >= 20
Number when divided by 3 is equal to the sum of the number and 2?
Let 'x' be "The Number".x/3 = x + 2Multiply both sides of the equation by 3:x = 3x + 6Subtract 6 from each side:x - 6 = 3xSubtract 'x' from each side:-6 = 2xDivide each side by 2:-3 = x
How do you work out 8 equals 5n plus 4?
You're not really sure what you're looking for, are you.You're looking for the number that 'n' must be to make the statement true.Here's how to find it:8 = 5n + 4Subtract 4 from each side of the equation:4 = 5nDivide each side by 5:4/5 = n
Find the number when the product of 7 and a number is increased by 7 and the result is 12?
7n + 7 = 12Subtract 7 from each side of the equation :7n = 5Divide each side by 7 :n = 5/7
3 times the sum of a number and 2 is 12?
This can be expressed as: 3(x+2) = 12so, divide both sides by 3(x+2) = 4subtract 2 from both sidesx = 2
Nine plus the quotient of a number b and ten is greater than or equal to eleven?
9 + b/10 >= 11Subtract 9 from each side :b/10 >= 2Multiply each side by 10 :b >= 20
Number when divided by 3 is equal to the sum of the number and 2?
Let 'x' be "The Number".x/3 = x + 2Multiply both sides of the equation by 3:x = 3x + 6Subtract 6 from each side:x - 6 = 3xSubtract 'x' from each side:-6 = 2xDivide each side by 2:-3 = x
How do you find the prime factorization of 30?
30 = 2 x 3 x 5Divide the number by the smallest possible prime until you have only prime factors.30 / 2 = 1515 / 3 = 5The factors are 2 x 3 x 5.
Is the root of 7x-2 equals 3 an odd number?
Well, let's see. First we'll have to figure out what 'x' is:7x - 2 = 3Add 2 to each side of the equation:7x = 5Divide each side by 7 :x = 5/7 .I don't think 5/7 is an odd or an even number.
How do you determent the probability?
To determine a probability:Take the number of outcomes that you wantDivide it by the number of total possible outcomesFor example, to determine the probability of taking a green ball out of a bag with 5 red balls, 5 blue balls and 5 green balls:Take the number of outcomes that you want: 5Divide it by the number of total possible outcomes: 15 divided by 5 = 1/3Write the answer as a fraction (eg. 1/3), a decimal (eg. 0.33) or a percentage (eg.33%).
How do you subtract 10 and three fourths away from 7 and one fourths?
7 1/4 - 10 3/4 [your answer will be negative]first make them into improper fractions29/4 - 43/4subtract the top terms and leave the denominator constant-14/4convert into a mixed number-3 1/2
How do you work out 8 equals 5n plus 4?
You're not really sure what you're looking for, are you.You're looking for the number that 'n' must be to make the statement true.Here's how to find it:8 = 5n + 4Subtract 4 from each side of the equation:4 = 5nDivide each side by 5:4/5 = n
How do you Write the decimal number 2365 as a base 7 number?
Divide the number by the new base (7 in this case) to give a quotient (result) and remainder.Note the remainderMake the number the quotientIf the quotient is not zero repeat from step 1Write the remainders in reverse order (last found first)That's how I write a decimal number in any other base.This is me doing it for 2365 in to base 7:2365 ÷ 7 = 337 r 6337 ÷ 7 = 48 r 148 ÷ 7 = 6 r 66 ÷ 7 = 0 r 6⇒ 236510 = 66167
What is the answer to 10x plus 4 equals 4x plus 9?
The "answer" is the number that 'x' has to be in order tomake the statement true. It's usually called the "solution".10x + 4 = 4x + 9Subtract 4x from each side of the equation:6x + 4 = 9Subtract 4 from each side:6x = 5Divide each side by 6:x = 5/6
When the sum of a number plus 3 is squared it is 13 more than the number plus 2 when squared?
Let us give this unknown number the symbol x , then you can formulate this equation:( x + 3 )^ 2 = 13 + ( x + 2)^ 2x^2 + 6x + 9 = 13 + x^2 + 4x + 4subtract x^2 from both sides, you'll obtain:6x + 9 = 4x + 176x - 4x = 17 - 92x = 8So, x=4
