D. 78.92 pounds

Answers

Answer 1

Answer: 1. Find the 20% of 840$ : 840 x 0,2 = 168$ (She will pay 168$)
2.840-168=672$
3.672 divided by 6 = 112$ per month

Which means , d) .

Answer:

250

Step-by-step explanation:

you have to use the fact that the big triangle and the small triangle are similar and write the proportions

$(125)/(10) =(AB)/(10)$ we took half of the side because of ΔABD and ΔBD..

AB= (125*10)/10=125

is AB =125 then AC is duble AC= 2*125=250

the true sentence is -1/3>-2/5.

What is number?

A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.

here, we have,

-1/3 , & -2/5

now,

i.e. -0.33 & -0.4

so, -0.33>-0.4

hence, the true sentence is -1/3>-2/5.

10x f ( 7 ) + 9 x g(-1) =

Answers

The value of the expression is 3439 in the given case of $10x f ( 7 ) + 9 x g(-1)$

To solve the expression $10x * f(7) + 9 * g(-1)$ , we need to know the specific functions f(x) and g(x) and their corresponding values at x = 7 and x = -1. Once we have this information, we can substitute the values and then perform the calculations to find the result.

For example, if the functions are defined as follows:

$f(x) = x^2\ng(x) = 2x + 3$

Then, we can evaluate the expression as follows:

$f(7) = 7^2 = 49\n\ng(-1) = 2(-1) + 3 = 1$

Now, substitute the values back into the expression:

$10x * f(7) + 9 * g(-1) = 10 * 7 * 49 + 9 * 1 = 10 * 343 + 9 = 3430 + 9 = 3439$

So, the value of the expression is 3439.

$10x f ( 7 ) + 9 x g(-1)$

Answer:

what are you trying to look for the variables or answer?

Step-by-step explanation:

Which expression is in simplified form for the given expression and states the correct variable restriction? u^2-4/(u-6)(u-2)
a. 1/u-3, u=3
b. u+2/u-6, u=2, u=6
c. 1/2u+12, u=-6
d. u+2/u-6, u=6

Answers

(u^2 - 4) / (u-6)(u-2)

Resriction u ≠ 6 and u ≠ 2 (because the denominator cannot be equal lto zero)

Simplification

u^2 - 4 is a difference of two squares, then you can factor it as the product of (u+2)(u-2). So, you can write the expression as:

(u+2)(u-2) / (u-2)(u-6)

Simplify u -2 (because it appears in the numerator and the denominator)

(u + 2) / (u -6), with u ≠2 and u≠6
