The sum of two numbers is 55. The smaller number is 15 less than the larger number. What are the numbers?
Answer:
a=35
b=20
Step-by-step explanation:
a+b =55
a=b+15
b+15 +b =55
2b=55 - 15
2b=40
b=40 :2
b=20 (the smallest number)
a=20 +15 =35 (the largest number)
Step-by-step explanation:
55=x+15
-15 -15
40=x

Answer:
No solutions
Step-by-step explanation:
5x^3 + 2 + 7x^2 = 7x^2 + 5x^3 +2
125x + 2 + 49x = 49x + 125x + 2
-125x -125x
2 + 49x = 49x + 2

Answer:
diabetes
Step-by-step explanation:
if α,β are the roots of the equation x^{2}-3x+2=0 form an equation whose roots are (α+β)² & (α-β)²
Solution:-
Let's find roots of x² - 3x + 2
=> x² - 3x + 2 = 0.
=> x² - x - 2x + 2 = 0.
=> x ( x - 1 ) -2 ( x - 1) = 0.
=> ( x - 1 ) ( x - 2 ) = 0.
=> x = 2, 1.
Now
( a + ß )² = (2+1)²=3²=9( a - ß )² = ( 2 - 1 )² = 1² = 1.So , equⁿ would be ,
=> x² - ( 9 + 1)x + 9×1=0.
=> x² - 10x + 9=0.
WILL DO BRAINLIEST IF RIGHT ASAP Evaluate the expression for r = –2. –40(–31 − 16r)2 + r2 =
Answer: -36
Step-by-step explanation:
To evaluate the expression, you want to plug in r to solve.
-40(-31-16(-2))²+(-2)² [parenthesis]
-40(1)²+(-2)² [exponent]
-40+4 [add]
-36
Now we know the expression is equal to -36 when r=-2.
Write an algebraic expression for each verbal expression: 1.) The product of 5 and twice a number x, decreased by the product of 3 and that same number. 2.) Twice the sum of a number x, and another number y, increased by the product of the first number squared and 8
Answer:
1) (5 times 2x) - (3 times 2x)
2) x+y) times 2 + (x*2 times 8)
explanation:
for "times" put a multiplication sign and the astric ( * ) is for the exponent or meaning "to the power of" :)
The first equation will be formed as: [tex](5 times 2x) - (3 times 2x)[/tex]
The second equation will be performed as [tex](x + y) times\ 2 + (x*2 \ times 8)[/tex]
What is multiplication?When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however other symbols like the "*" sign are also occasionally used.
1.) The composition of 3 and that identical number, multiplied by 5, lowered by the products of 5, and double that amount will be represented as (5 times 2x) - (3 times 2x)
2.) The product of the square root of the first variable and eight times a quantity x and a quantity will be represented as (x+y) times 2 + (x*2 times 8)

How do you work out the gradient of a line?
Step-by-step explanation:
The gradient of the line = (change in y-coordinate)/(change in x-coordinate) . We can, of course, use this to find the equation of the line. Since the line crosses the y-axis when y = 3, the equation of this graph is y = ½x + 3 . To find the gradient of a curve, you must draw an accurate sketch of the curve.
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Solve 2s^3 - 4r^2 = if r = 1 and s = 5
The Value of the expression 2s³ - 4r² by substituting the given values into the expression is 246
Given the equation ; 2s³ - 4r²
Value of r = 1 ; value of s = 5To solve, substitute the values of r and s into the equation :
2(5)³ - 4(1)²
2(5 × 5 × 5) - 4(1 × 1)
2(125) - 4(1)
250 - 4
= 246
Therefore, the final value of the expression by substituting the value of r and s as 1 and 5 respectively is 246

Solve 0.5y+y/3=0.25y+7
please answer this question
Answer:
y = 28
Step-by-step explanation:
0.5y + y/ 3 = 0.25y + 7
1.5y / 3 = 0.25y + 7
y/2 = 0.25y + 7
y = ( 0.25y + 7)*2
y = 0.5y + 14
y - 0.5y = 14
0.5y = 14
y = 14/0.5
y = 28
