ray is x years old
Ron is x+y years old
in 5 years ron will be 5 years older than now, so x+y+5 years old
orAnswer:
x - x + y + 5 - 5 = y or x + y - x = y
Step-by-step explanation:
The difference now,
x + y - x = y
The difference in 5 years,
(x + y + 5) - (x + 5) = x - x + y + 5 - 5
x - x + y + 5 - 5 = y
The difference in their ages never changes

Answer:
x = 4/3
y = 0
z = 5/4
Step-by-step explanation:
PQ means multiplied matrices.
P+Q means added matrices.
PQ = =
4x+0 4y+0z 4x 4y
0x+5×0 0y+5z 0 5z
P+Q = =
4+x 0+y 4+x y
0+0 5+z 0 5+z
so, for PQ = P+Q we have
4x = 4+x
4y = y
5z = 5+z
4x = 4 + x
3x = 4
x = 4/3
4y = y
3y = 0
y = 0/3 = 0
5z = 5 + z
4z = 5
z = 5/4

if h=5 what is 2 x (6-h
Answer:
Step-by-step explanation:
Equation : 2 × (6 - h)
Because h = 5, replace the variable h with 5.
2 × (6 - 5)
Solve the equation in the parentheses.
6 - 5 = 1
The equation is now 2 × 1, which is equal to 2.
So, 2 × (6 - h) is 2.

The possible rational roots are ±1, ±3, ±5, ±9, ±15, and ±45.
The actual roots ordered from least to greatest are?
The actual roots of the function P(x) = x^4 - 4x^3 - 4x^2 + 36x - 45 are its real roots
The actual roots ordered from least to greatest are -3 and 3
How to determine the actual roots?From the complete question, the polynomial function is:
P(x) = x^4 - 4x^3 - 4x^2 + 36x - 45
Expand the above equation
P(x) = x^4 - 4x^3 + 5x^2 - 9x^2 + 36x - 45
Factorize the equation
P(x) = x^2(x^2 - 4x + 5) - 9(x^2 - 4x + 5)
Factor out x^2 - 4x + 5
P(x) = (x^2- 9)(x^2 - 4x + 5)
Express x^2 - 9 as a difference of two squares
P(x) = (x + 3)(x - 3)(x^2 - 4x + 5)
The expression (x^2 - 4x + 5) cannot be factorized.
So, we have:
P(x) = (x + 3)(x -3)
Equate to 0
(x + 3)(x -3) = 0
Expand
x + 3 = 0 or x - 3 = 0
Solve for x
x = -3 or x = 3
Hence, the actual roots ordered from least to greatest are -3 and 3

18/5 divided by 3/25
[tex] \frac{18}{5} \div \frac{3}{25} [/tex]
Answer:
30
Step-by-step explanation:
There are a few different ways we can approach this problem.
The easiest way is to flip the second fraction and multiply:
[tex]\dfrac{18}{5} \div \dfrac{3}{25}=\dfrac{18}{5} \times \dfrac{25}{3}=\dfrac{18 \times 25}{5 \times 3}[/tex]
To do this without a calculator, rewrite 18 as 6 x 3 and 25 as 5 x 5:
[tex]\dfrac{18 \times 25}{5 \times 3}=\dfrac{6 \times 3 \times 5 \times 5}{5 \times 3}[/tex]
Now we can cancel out the common factors of 5 and 3 from the numerator and denominator, and are left with:
[tex]\implies 6 \times 5 =30[/tex]
The quotient obtained from the division of given fractions is 30.
Given that, 18/5 divided by 3/25.
Dividing fractions is nothing but multiplying the fractions by reversing one of the two fraction numbers or by writing the reciprocal of one of the fractions. By reciprocal we mean, that if a fraction is given as a/b, then the reciprocal of it will b/a.
Here, 18/5 ÷ 3/25
= 18/5 × 25/3
= 6/1 × 5/1
= 30/1
Therefore, the quotient obtained from the division of given fractions is 30.

If you're doing this by hand, writing the equation in Horner form can make it easier to evaluate.
f(x) = (5x -7)x +1
Then ...
f(-2) = (5(-2) -7)(-2) +1 = (-17)(-2) +1 = 34 +1 = 35
f(-1) = (5(-1) -7)(-1) +1 = (-12)(-1) +1 = 12 +1 = 13
f(0) = 1 . . . . the constant term
f(1) = (5(1) -7)(1) +1 = (-2)(1) +1 = -2 +1 = -1
f(2) = (5(2) -7)(2) +1 = (3)(2) +1 = 6 +1 = 7
In order, the f(x) values are 35, 13, 1, -1, 7.

How much of each ingredient is needed to make 35 flapjacks by following this recipe?
Recipe: Makes 10 flapjacks
140 g margarine
120 g sugar
100 ml syrup
240 g oats
50 g raisins
Answer:
Multiply each measure of ingredients by 3.5
Step-by-step explanation:
This recipe makes 10 flapjacks. We want to be able to make 35 flapjacks.
Divide 35 by 10 to find the ratio of these 2 numbers.
35 / 10 = 3.5
Now we can multiply the measures by this number to find out how much of each ingredient we need.
140 * 3.5 = 490
120 * 3.5 = 420
100 * 3.5 = 350
240 * 3.5 = 840
50 * 3.5 = 175
Answer:
Recipe: Makes 35 flapjacks
490 g Margarine
420 g sugar
