Answer:

The answer is 8

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

Answer:

0.5

Step-by-step explanation:

Answer:

1/5

Step-by-step explanation:

It's okay, you're not dum, you might have just not payed attention in online class or you might have forgotten.

We can find the slope by using 2 coordinates that are on a line.

We can choose any of the coordinates from this table. I'm gonna use (0, 4) and (2, 5)

The formula for find the slope is the rise over the run or

y1 - y2 / x1 - x2

4 - 5 / 0 - 5

-1 / -5

1/5

The slope is 1/5

Given:

16 emails to 6 text messages- 10 emails to 4 text messages

To find:

Whether 16 emails to 6 text messages- 10 emails to 4 text messages proportional or not.

Solution:

Check the ratio of emails to text. If the ratios are equal then the relation is proportional.

16 emails to 6 text messages.

[tex]\dfrac{Emails}{Text}=\dfrac{16}{6}[/tex]

[tex]\dfrac{Emails}{Text}=\dfrac{8}{3}[/tex]

[tex]\dfrac{Emails}{Text}=8:3[/tex]

10 emails to 4 text messages.

[tex]\dfrac{Emails}{Text}=\dfrac{10}{4}[/tex]

[tex]\dfrac{Emails}{Text}=\dfrac{5}{2}[/tex]

[tex]\dfrac{Emails}{Text}=5:2[/tex]

Since [tex]\dfrac{8}{3}\neq \dfrac{5}{2}[/tex] or [tex]8:3\neq 5:2[/tex], therefore, it is not proportional.

Answer:

b

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

since the shaded area is before x=-3 and x=-3 is a dashed line, x<-3 is the answer for x. That knocks out half the answers. the slope intercept form for the other line is y=-x-1. The answer with the slope as y would be the answer for the second half. A has both answers correct. (sorry for bad explaination, I am not a native speaker)

Answer: the value of a is less than b because its to the left

x=4

Step-by-step explanation:

5x-2.5=17.5

5x=17.5+2.5

5x=20

x=20/5

x=4

The solution of the given equation is x=4

An equation represents equality of two or more mathematical expression.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

We are given the equation as;

5x-2.5=17.5

Solving for x;

5x=17.5+2.5

5x=20

x=20/5

x=4

Step-by-step explanation:

I found the anser by multiplying 5 * 4 = 20, and then multiplying 2 * 2 = 4, then 3 * 2 = 6. Next you add 6 and 4, which equals 10. Finally you subtract 10 from 20 to find your answer of ten.

Answer: $‭3,927‬

Step-by-step explanation:

The interest will accrue as a simple interest rate for 10 years and then the grace period of six months.

The total time is therefore: 10.5 years.

Interest for those 10.5 years is:

= Loan amount * No. of periods * interest rate

= 5,500 * 10.5 * 6.8%

= $‭3,927‬

Answer:

x = 3

Step-by-step explanation:

[tex] \triangle TFG\sim \triangle TUV... (given) [/tex]

[tex] \therefore \frac{FG}{UV}=\frac{TG}{TV} ... (csst) [/tex]

[tex] \therefore \frac{45}{63}=\frac{10x+5}{49} [/tex]

[tex] \therefore \frac{5}{7}=\frac{10x+5}{49} [/tex]

[tex] \therefore 10x+5= \frac{5\times 49}{7} [/tex]

[tex] \therefore 10x+5=5\times 7 [/tex]

[tex] \therefore 10x+5=35 [/tex]

[tex] \therefore 10x=35-5 [/tex]

[tex] \therefore 10x=30 [/tex]

[tex] \therefore x=\frac{30}{10} [/tex]

Hello!

The common denominator is 100.

~Sophia

Answer:

A

Step-by-step explanation:

For the equation to be true, any number that would be multiplied by 7/5 should give us a number that is less than 7/5.

This means any number we are going to use to multiply 7/5 must not be less than 1.

²/3 is less than 1.

Let's multiply and see:

⁷/5 × ⅔ < ⁷/5

14/15 < ⁷/5 (this is true because ⁷/5 is greater than 14/15)

Therefore, the answer is A.
