How do you write 25 and b more in an expression in algebra?
25 + b
A's salary is 25 percent more than B's salary. How much percent is b's salary on A's salary?
Let's use an example. Let's say B's salary is $100. Since A's salary is 25% more, that makes A's salary $125. So B's salary as a percentage of A's salary is 100/125 = 80% Without using an example: Let a be A's salary and let b be B's salary. a = b + 25%b = b + .25b = 1.25b b/a = b/(1.25b) = 1/1.25 = .80 = 80%
One number is 25 percent of another The larger number is 12 more than the smaller What are the numbers?
Let the numbers be represented by a and b with a < b. Then a = b.25/100 and b = a + 12 As a = b.25/100 then 100a = 25b : 4a = b As b = a + 12 then substituting for b gives, 4a = a + 12 : 3a = 12 : a = 4. If a = 4 then b = a + 12 = 4 + 12 = 16 The two numbers are 4 and 12.
The sum of two numbers is 25 while their difference is 11. What are the two numbers?
If a + b = 25 and a - b = 11 as asked, we can solve like this: a - b = 11 => a = 11 + b [Now we have expressed a in terms of b. Let's substitute that information in the first equation.] a + b = 25 => (11 + b) + b = 25 => 11 + b + b = 25 => 11 + 2b = 25 => 2b = 14 => b = 14/2 & b = 7 Substitute the value for b (the 7) into either equation and solve like this: a + b = 25 => a + 7 = 25 => a = 25 - 7 & a = 18 Lastly, substitute your answers into either equation and see if it checks.
Inside the B-25 bomber?
There was an inside to the B-25, yes. What about it?
If the value of b is 7 then what is the value of expression -3b-25?
replace b with 7 so you must first multiply -3 by 7 which gives you -21. Subtract 25 more and you get -46, which is the answer.
What is the wingspan of the B-25 Michell Bomber?
The wingspan of the B-25 is 67 ft,7 inches. - More than 100 of these great aircraft are still in existence, almost 50 of them still flying !
The square of the third of three consecutive integers is equal to twenty-five more than the product of the first two. What are the integers?
Let the three consecutive integers be a, b, & c. Square of c is 25 more than a*b:c2 = 25 + a*b; also the integers are consecutive, so a+1 = b & b+1 = cput a & b in terms of c, so b = c-1 & a = b-1 = c-2, substitute these into original equation:c2 = 25 + (c-2)*(c-1) = 25 + c2 - 3*c +2 --> c2 = 27 + c2 - 3*c --> 0 = 27 - 3*cc = 9 and from the 'consecutive' equations: b = 8& a = 7Substitute these values back into the original equation to make sure it works.92 = 81 and 8*7 = 56. 81 is 25 more than 56.
Find two complementary angles such that the measure of the first angle is 25 degrees less than the measure of the second?
If the angles are A nd B, then A + B = 90 and A = B - 25 So B - 25 + B = 90 or 2B = 115 or B = 57.5 and then A = 32.5
What is 25 percent of equals 7?
Let B = base25% = 0.25Equation: 25% of B = 70.25 * B = 7B= 7/0.25B= 28therefore, 25% of 28 equals 7.
2times b is25 what is b?
2b = 25 b = 12.5
10a-5b equals 25 what is b?
10a - 5b = 25 So 5b = 10a - 25 and hence b = 2a - 5
