Ann has two more than twice the amount of toffees Mary has. Total number of

toffees among them is 11. (i) Assuming the number of toffees Mary has is x, build up an equation.​

9514 1404 393

Answer:

  90°

Step-by-step explanation:

The largest angle is 6 of the 6+1+5 = 12 ratio units, so is 6/12 = 1/2 of the total number of degrees in a triangle.

The largest angle is 1/2(180°) = 90°.

Answer:

Lets say that m is months

Every month she deposits 30 so that is 30m

lets say t is time

t = 30m > 120

After 4 months, she will have exactly $120. In 5, she will have more.

Step-by-step explanation:

Answer:

she can use 14.025 gigabytes

By "state the universe" I suppose you mean "domain". log₂(x ² + 3x + 2) is defined for

x ² + 3x + 2 = (x + 1) (x + 2) > 0   →   x < -2   or   x > -1

(To solve the inequality, consider values of x between the ones that make the expression exactly equal to 0, in this case x = -2 and x = -1. We have, for instance, for x = -3, that (-3)² + 3(-3) + 2 = 2 > 0, so x ² + 3x + 2 > 0 for all x < -2.)

Now solve the equation: Write both sides as powers of 2 to eliminate the logarithm on the left:

[tex]\log_2(x^2+3x+2)=1\implies 2^{\log_2(x^2+3x+2)}=2^1\implies x^2+3x+2=2[/tex]

Solve the remaining quadratic:

x ² + 3x + 2 = 2

x ² + 3x = 0

x (x + 3) = 0

x = 0   or   x = -3

Both of these solutions are within the presribed domain (-3 < -2 and 0 > -1), so we're done.

Answer:

F(x) ^-1= x+3/4

Step-by-step explanation:

Exchange f(x) for y

Y=4x-3

+3

Y+3=4x

/4

Y+3/4=x

Swap y and x

F(x)^-1= x+3/4

Answer:

It is a perfect square expression.

It factors to (x+2)^2

===========================================================

Explanation:

The general format for a perfect square is

(a+b)^2 = a^2 + 2ab + b^2

Which can be seen through the use of the FOIL rule.

Compare x^2+4x+4 with a^2+2ab+b^2, and we have these three equivalences:

Since x^2 = a^2, we can apply the square root to both sides to get a = x. Similarly, 4 = b^2 leads to b = 2. We could get b = -2, but that would mean 2ab = 2x*(-2) = -4x instead of 4x. So we'll stick with b = 2 instead.

Because a = x and b = 2, we then can say:

(a+b)^2 = a^2 + 2ab + b^2

(x+2)^2 = x^2 + 2*x*2 + 2^2

(x+2)^2 = x^2 + 4x + 4

Showing that x^2+4x+4 factors to (x+2)^2.

Answer:

y = 4x - 2

Step-by-step explanation:

Given: 4x=2+y

First, subtract 2 on both sides to isolate out y. (Slope-intercept form is y=mx+b)

Once subtracted, you get: 4x-2=y

Rearrange it, and you get: y=4x-2

Step-by-step explanation:

Solution for What is 12.5 percent of 40:

12.5 percent *40 =

(12.5:100)*40 =

(12.5*40):100 =

500:100 = 5

Now we have: 12.5 percent of 40 = 5

Question: What is 12.5 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$40=100\%$.

Step 4: Similarly, $x=12.5\%$.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$.

$x=12.5\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{12.5\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{12.5}{100}$

$\Rightarrow x=5$

Therefore, $12.5\%$ of $40$ is $5$

Answer:

at least 125 points on the final

Step-by-step explanation:

90% of 650 = 585

He needs at  least 585 points to get at least 90%

Since he averaged 92 on the first 5 tests, he already has 5(92) = 460 pts

That means he needs to get at least 585 - 460 = 125 pts on the final exam

Answer:

- x² + 8x - 15

Step-by-step explanation:

Given

(5 - x)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

5(x - 3) - x(x - 3) ← distribute parenthesis

= 5x - 15 - x² + 3x ← collect like terms

= - x² + 8x - 15 ← in standard form
