Answer:

[tex]x + y = -2\\x-y=8[/tex]

Step-by-step explanation:

3 is the [tex]x[/tex], and -5 is the [tex]y[/tex].

1) Create two equations that add and subtract them.

[tex]x + y = -2\\x-y=8[/tex]

2) Check whether you get the same answer (3,-5) or not. To do so, you need to solve them simultaneously using the elimination or substitution method. I will demonstrate using the substitution method.

[tex]x = -2 - y\\x-y=8\\(-2 - y) -y =8\\-2-2y=8\\-2y = 8 + 2\\-2y = 10\\y = \frac{10}{-2} \\y = -5[/tex]

To find [tex]x[/tex], substitute the result into one of the two equations. I choose [tex]x+y=-2[/tex].

[tex]x-5=-2\\x = -2 +5\\x = 3[/tex]

Answer: C. Forty dollars.

Step-by-step explanation: $5 times eight hundreds equals forty, therefore you will get $40 from the bank.

40 if u take 100 8 times then it will be 800 and You only times 8by 5 then or 5by 8

also if possible can i have brainliest

Step-by-step explanation:

I'm assuming the question is how many miles in total did mary swim.

if this is the case then we just multiply the number of days by the number of miles per day.

Hence,

3/4 × 8 = 6

so 6 miles in total.

Step-by-step explanation:

[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill &\$3000\\ P=\textit{original amount deposited}\dotfill &\$2000\\ r=rate\to 9.5\%\to \frac{9.5}{100}\dotfill &0.095\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{semiannually, thus twice} \end{array}\dotfill &2\\ t=years \end{cases}[/tex]

[tex]3000=2000\left(1+\frac{0.095}{2}\right)^{2\cdot t} \implies \cfrac{3000}{2000}=1.0475^{2t}\implies \cfrac{3}{2}=1.0475^{2t} \\\\\\ \log\left( \cfrac{3}{2} \right)=\log(1.0475^{2t})\implies \log\left( \cfrac{3}{2} \right)=t\log(1.0475^{2}) \\\\\\ \cfrac{\log\left( \frac{3}{2} \right)}{\log(1.0475^{2})}=t\implies 4.37\approx t\qquad \textit{about 4 years and 4 months and a half}[/tex]

Answer: 35

Step-by-step explanation: The reason is that 7 × 5 = 35 and when you multiply two negative numbers they make the answer positive. I hope this helped!

Answer:

35

Step-by-step explanation:

7 times 5 equals 35. Even though the two numbers are positive, the product will be negative, because a negative times a negative equals a positive. A negative times a negative will equal a positive because what was originally negative has been reversed in direction.

So, the answer is 35.

Answer:

57/40

Step-by-step explanation:

So we need to find the LCD, or the least common denominator.  The LCD is 40.  Now, we do a transition to find the new numerator.

[tex]\frac{4}{5} =\frac{x}{40} \\\\\\frac{5}{8} = \frac{x}{40}[/tex]

The new equation is this:

[tex]\frac{32}{40} +\frac{25}{40}[/tex]

Now we use our common sense.  32+25=57

57/40.

Answer:

2/9

Step-by-step explanation:

12,14,16,18 are all greater than 10, which is 4/18 numbers, simplified as 2/9

Answer: 13/18

Step-by-step explanation:

First you add up the amount of even numbers and the amount of numbers greater than 10

2,4,6,8,10 make 5 then add 8 more for 11-18, leaving you with 13 then take 13 and divide it by the total (18) and you will get 0.72 or 13/18

Based on the variable costs and contribution margin, the unit sales price is $80 and the unit contribution margin is $32.

The sales volume in units needed to earn $600,000 is 43,750 units and the amount in dollar sales needed is $3,500,000.

The unit sales price can be found as:

= Variable cost / (1 - contribution margin ratio)

= 48 / (1 - 40%)

= $80

Unit contribution margin is:
= Selling price x Contribution margin ratio

= 80 x 40%
= $32

In units, this amount is:
= (Fixed cost + income required) / Contribution margin

= (800,000 + 600,000) / 32

= 43,750 units

In dollar terms the amount needed is:

= Units needed x selling price

= 43,750 x 80

= $3,500,000

First, we need to find how many years are in between 1977 and 2004:
2004-1977 = 27

And the different between the prices:
175-15 = $160

Since this is supposed to be linear, we can do 160/27 which is about 5.925.

We can round this out to be about $6 cheaper per year, or $5.90.

Answer:

No

Step-by-step explanation:

Tyler is incorrect. The only way you can set individual terms equal to the result is when the result is zero. This is due to zero times anything equalling zero. If one of the terms equals zero, then the other term does not matter because the whole thing will be zero. Let's say:

[tex](2 - x)(x + 1) = 0[/tex]

If the first term equals zero, the entire left side is zero. For Priya's case, the right side is not zero, it is 11. If one term is 11, the other term will contribute. You can check this by plugging in Tyler's solutions. The correct way to solve this equation is to use FOIL on the two terms, then subtract 11 on both sides to get zero. Then use the quadratic formula.

Answer:

16

Step-by-step explanation:

well, if you remember P.E.M.D.A.S, which is the order for doing equations, the first two dont matter, but from M for Multiplication, D for Division, A for addition, and finally S for Subtraction, those are the ones that you need here. So you divide the 9s first giving you 9-1+9-1=8+8=16.
