Answer: m is less than or equal to -7
Step-by-step explanation:
Step-by-step explanation:
[tex]-2m - 3 \leq 11[/tex]
[tex]-2m \leq 14[/tex] (adding 3 to both sides)
[tex]m\geq -7[/tex] (dividing by a negative switches the sign around)

Solve the system of equations using elimination
2x + y = 5
-1x + y = 2
Answer:
(1, 3 )
Step-by-step explanation:
Given the 2 equations
2x + y = 5 → (1)
- x + y = 2 → (2)
Rearrange (1) expressing y in terms of x by subtracting 2x fro both sides
y = 5 - 2x → (3)
Substitute y = 5 - 2x into (2)
- x + 5 - 2x = 2
- 3x + 5 = 2 ( subtract 5 from both sides )
- 3x = - 3 ( divide both sides by - 3 )
x = 1
Substitute x = 1 into (3) for corresponding value of y
y = 5 - 2(1) = 5 - 2 = 3
solution is (1, 3 )

Objects on Jupiter weigh 240% of their weight on Earth. If an object weighs 30.5 pounds on Earth, how many pounds would it weigh on Jupiter?
Answer:
732
Step-by-step explanation:
It is 732 because if we start off with 30.5 and then get our 240%, what will happen next is that we will move the decimal spot 2 places on the 240%. So 240% now becomes .240 and NOT a percent yet because we need to do one more thing. After we do this we can then do 30.5x.240 which leads to 7.32. But because this number is too small and it even wouldnt make sense in this question, now we move the decimal spot to the right, so before we did left but now we go right. And when we do this it will finally give out answer of 732 pounds.

if a-b=14,ab=8 find a^2+b^2
Here,
a-b=14
ab=8
we know that,
[tex]\tt{(a-b)^2=a^2+b^2-2ab }[/tex] ⠀
According to the question,
[tex]\tt{ (14)^2=a^2+b^2-2×8 }[/tex] ⠀
[tex]\tt{196=a^2+b^2-16 }[/tex] ⠀
[tex]\tt{a^2+b^2=196-16 }[/tex] ⠀

When the expression 10^2021 − 2021 is evaluated, the result is a very large number.
You probably do not have enough time to perform the calculation. So, in an
effort to save you some time and paper, instead of evaluating the expression
10^2021 − 2021, determine the sum of the digits in the difference. How do I do this pls
Answer:
18,176
Step-by-step explanation:
Figure out an easier thing to do: 1000 - 2021 = 9,797.
Therefore, our answer will be like 9999999999999999999999997979. Out of all of these digits, there are only 2 that arent nines. We know the amount of digits since it's 10^2021 power. We will have one less since we are subtracting 2021. Therefore, 2020 digits in total. Now we know of those 2020 digits, 2 of them are 7, therefore 2018 of them are 9s. That means do 2018(9) + 2(7) = 14 + 18,162 = 18,176.

12b-
34
3c
E
w
b =
Answer:
b = 10, c = 9
Step-by-step explanation:
For the triangles to be congruent by the HL postulate, then
UW = DF ( hypotenuse are congruent ), that is
12b - 34 = 5b + 36 ( subtract 5b from both sides )
7b 0 34 = 36 ( add 34 to both sides )
7b = 70 ( divide both sides by 7 )
b = 10
and
UV = EF ( legs are congruent )
4c - 9 = 3c ( subtract 3c from both sides )
c - 9 = 0 ( add 9 to both sides )
c = 9

Jesse has to save 60% of the total cost to go to a sports camp during the summer. The total cost was $500. What was the total amount Jesse saved? Make sure to explain how you got it.
Answer:
$300
Step-by-step explanation:
The total cost is $500 so you must find 60% of that. To find percentage divide 60% by 100 which turns it into .60, and then you multiply .60 by 500. This equals to 300. So, Jesse 60% of 500 is 300, and so Jesse had to save $300

What are the outputs of the following function?
{(-3, 2), (-4, 2), (8, 3), (7, 1)}
{1, 2, 3}
{3, 2, 1, 2}
{-3, -4, 2, 1, 7, 8, 3}
{1, 2, 3, -4, 7}
Answer:
Answer: {1, 2, 3}
Step-by-step explanation:
Functions
They are relations between input values and output values such that each input has one and only one output.
The function:
{(-3, 2), (-4, 2), (8, 3), (7, 1)}
Consists of four ordered pairs where the first component is the input value and the second value is the output value.
It can be identified that the output values are:
{2,3,1}
In any order, thus the first choice is correct.

Randalstown rugby club play 20 matches and win 17 of there matches. What percentage of the matches did they win
Answer:
They won 85% of their matches
Step-by-step explanation:
Here, we want to calculate the percentage of wins

number of wins/number of games * 100%
That would be;
17/20 * 100%
= 17 * 5 = 85%
