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

Kevin plant a total of 72 flowers in equal rolls. Can you plant six rolls of yellow flowers and two rows of my flowers. How many flowers are in each row?
Answer:
9
Step-by-step explanation:
72 flowers in 8 equal rows will have 9 flowers in each row.
__
72 = 8 × 9
Answer:
There are 9 flowers in each of the 8 rows
Step-by-step explanation:
Kevin plants a total of 72 flowers in equal rows he plants 6 rows of yellow flowers and 2 rows of red flowers how many flowers are in each row
Solution
Total flowers = 72 in Equal rows
Yellow flowers = 6 rows
Red flowers = 2 rows
Rows of yellow flowers + Rows of rec flowers = 6 + 2
= 8 rows
Flowers in each row = Total flowers / total rows
= 72 flowers / 8 rows
= 9 flowers
Flowers in each row = 9 flowers

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)

(1/4*12)+(1/4*8x)
Multiple those out to get a new equation
3+2x
You cannot add those together because of the variable. Theres no way of knowing what x equals so this is as far as you can go therefor making the answer 3+2x
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.

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

Line GH bisects angle FGI, that means angle FGH = angle HGI
To Find:the value of x and angle FGI
Solution:angle FGH = angle HGI
6x - 11 = 4x + 7
or, 6x - 4x = 7 + 11
or, 2x = 18
or, x = 18/2 = 9
angle FGI = angle FGH + angle HGI
or, angle FGI = 6x - 11 + 4x + 7
or, angle FGI = 10x - 4
By putting the value of x, we get
angle FGI = 10(9) - 4
or, angle FGI = 90 - 4 = 86°
Answer:The value of x is 9.
Angle FGI = 86°

How many solutions does y=-x^2-4x+7 have
Answer:
x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
Step-by-step explanation:
Solve for x:
y = -x^2 - 4 x + 7
y = -x^2 - 4 x + 7 is equivalent to -x^2 - 4 x + 7 = y:
-x^2 - 4 x + 7 = y
Multiply both sides by -1:
x^2 + 4 x - 7 = -y
Add 7 to both sides:
x^2 + 4 x = 7 - y
Add 4 to both sides:
x^2 + 4 x + 4 = 11 - y
Write the left hand side as a square:
(x + 2)^2 = 11 - y
Take the square root of both sides:
x + 2 = sqrt(11 - y) or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
x = sqrt(11 - y) - 2 or x + 2 = -sqrt(11 - y)
Subtract 2 from both sides:
Answer: x = sqrt(11 - y) - 2 or x = -sqrt(11 - y) - 2
