Given that x+y = 7 and 3x+y = 45, evaluate x^2-y^2.

Answers

Alright, If x+y=7 then y=7-x. If we plug that in then 3x+7-x=45 leads that 2x+7=45 so 2x=38, therefore, x=19 now if x+y=7 and x=29 we know that y=-22. Hope this helped! Try finding the answer now!

What would be the final value on a certificate of deposit worth $2,000
over a period of 5 years with an interest rate of 2%?

Answers

Answer:

the "final value" will be $2,200

Step-by-step explanation:

Assume that this is a case of simple interest (no compounding involved).  The appropriate formula is:

A = Prt, where P is the principal, r is the interest rate as a decimal fraction, and t is the number of years.

Here,

Interest = $2,000(0.02)(5) = $200

Adding this $200 in interest to the principal, we find that the "final value" will be $2,200.

The answer is 2,200 hope you got it right

Step-by-step explanation:

Answer:

a.27

b.54

c.216

Step-by-step explanation:

So we start by dividing 135 by 5, getting 27, which is the answer for the first problem, then you double it to get the answer for the second, which is 54, then you add the three number together 27+54+135=216

A man drove his car a distance of 315 miles in 5 hours. If continuing at this rate is possible, he will travel ____ miles in 9 hours. (5 points)

Answers

He will travel 567. You first divide 315 by 5 and then that’s your rate. Then you multiply your rate by 9 to get 567 as your answer

Answer:

567

Step-by-step explanation:

Well, he traveled 63 miles every hour

So,

315+63=378

378+63=441

441+63=504

504+63=567

So, if he travels 63 miles an hour you can plus 63 to itself 4 times or you can times 63 to 4 then plus it to 315 then get your answer

You are at a pear picking farm and they allow you to pick up to 50 pears a day. Today, you have already picked 14 pears. Which inequality below would represent how many pears you can still pick, p?
(A) p − 14 ≤ 50
(B) p − 14 ≥ 50
(C) p + 14 ≤ 50
(D) p + 14 ≥ 50

Answers

Answer:

C

Step-by-step explanation:

P+ 14 would have to equal 50 or be less than 50

50-14= 36

P would equal 36

36+14 = 50

50 is less than or equal to 50

The required inequality represents the number of pears we can still pick is p + 14 ≤ 50. Option C is correct.

Given that,
we are at a pear-picking farm and they allow you to pick up to 50 pears a day. Today, you have already picked 14 pears. Which inequality below would represent how many pears you can still pick, p is to be determined.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

here,
Maximum pick-up caps = 50
for the day we pick = 14
Now,
The inequality that represents the number of remaining picks,
P ≤ 50 - 14
or
P + 14 ≤ 50

Thus, the required inequality represents a number of pears we can still pick is p + 14 ≤ 50. Option C is correct.

How do the expressions 72 divided by 9 and Negative 72 divided by (negative 9) compare when they are evaluated?

Answers

Answer:

They compare because they have the same answer.

Step-by-step explanation:

negative divided or multiplied by negative becomes positive.

-77 divided by 9 has the result of a negative number because when you do a negative number multiplied/divided by a positive number you get a negative number as your product. When you divide -77 by -9 you get a positive number. Because when you divide/multiply two numbers that are negative you get a positive product. So the answer for -77/9 is -8. -77/-9 is 8
