The temperature at a mountain base camp was −3 degrees Celsius on Monday. Tuesday morning, the temperature was 2 degrees Celsius lower than what it was on Monday. By Tuesday evening, the temperature was 4 degrees Celsius lower than what it was that morning. What was the temperature at the base camp Tuesday evening?
−9 degrees Celsius
−6 degrees Celsius
−5 degrees Celsius
−1 degree Celsius
Answer: -9 degrees Celsius
Step-by-step explanation: You subtract two degrees from -3 and get -5 (-3-2=-5). Then, you subtract 4 degrees from -5 and get the answer of -9 degrees Celsius.
Norma bought a plastic bag that contains 100 balloons. The label on the bag says that there are 20 each of blue, yellow, red, green, and orange balloons. Norma will take one balloon from the bag at random. What is the probability that the balloon will be either red or blue?
A)3/2
B)2/3
C)3/5
D)2/5
Answer:
d
Step-by-step explanation:
ur welcome plz mark brainliest
2/5 t is the probability that the balloon will be either red or blue.
Thus option A is correct.
What is probability?The mathematical discipline known as probability specializes in determining the possibility of an event occurring. Probability, which expresses the probability of a risk, is calculated by dividing the total possible combinations by the frequency of favorable events. Composite reliabilities vary from 0 to 1, with 1 representing certainty and 0 representing hesitation.
The probability of the event will be taken as
The fact that the data of red and blue will have a chance of occurring in the event
The first draw chance would be 20/100 = 1/5
The second draw would be 20/100 = 1/5
P = 20 / 100 + 20 / 100
P = 1/5 + 1/5
P = 2/5
Therefore, option D is the correct option.

having at least 636.47 to exchange to 540 marks
The estimated money Julie should carry with herself is $572.64
What is estimation?Estimating in maths is a way of approximately calculating an answer or to check its accuracy.
Given that, Julie figures that she will need at least 540 Marks (German money) to get the items she wants when visiting Germany.
To find how much currency she should carry, we will convert the US currency into German currency
$1.06 = €1
Therefore, €540 = 1.06x540 = $572.64

how do you change y – 5 = - (x – 1) into slope intercept form?
Answer:
y = -x + 6
Step-by-step explanation:
Slope intercept form is y = mx + b.
So distribute the negative sign on the right side to get:
y - 5 = -x +1
Then add the 5 on the left side to both of the sides to get y alone, then you will get:
y = -x +6
That is in slope intercept form.

Answer:
$308
Step-by-step explanation:
Let the amount earned be a
and hours be h
a ∝h
a = kh where k is the constant
if $70.00 is earned in 5 hours,
70 = 5k
k = 70/5
k = 14
For 22 hours, it is
a = kh
a = 14 × 22
a = 308

Answer:
2.(b) w= 3
3. x= -3 or x= 3
Step-by-step explanation:
2.(b) Method 1:
[tex] \frac{2w - 1}{5} + w + 2 = 2w \\ \frac{2w - 1}{5} = 2w - w - 2 \\ [/tex]
Simplify:
[tex] \frac{2w - 1}{5} = w - 2[/tex]
×5 on both sides:
[tex]2w - 1 = 5(w - 2)[/tex]
Expand:
[tex]2w - 1 = 5w - 10[/tex]
Bring constants to 1 side, w terms to the other:
[tex]5w - 2w = 10 - 1[/tex]
Simplify:
[tex]3w = 9[/tex]
Divide both sides by 3:
[tex]w = 9 \div 3 \\ w = 3[/tex]
Method 2:
[tex] \frac{2w - 1}{5} + w + 2 = 2w[/tex]
Multiply by 5 throughout:
[tex]2w - 1 + 5(w + 2) = 5(2w)[/tex]
Expand:
[tex]2w - 1 + 5w + 10 = 4w[/tex]
Simplify:
[tex]7w - 9 = 4w[/tex]
+9 on both sides:
[tex]7w = 4w + 9[/tex]
-4w on both sides:
[tex]7w - 4w = 9[/tex]
Simplify:
[tex]3w = 9[/tex]
Divide by 3 on both sides:
[tex]w = 3[/tex]
3. [tex] \frac{6x - 12}{3} + 4 = \frac{18}{x} [/tex]
Multiply by 3x on both sides:
[tex] \frac{3x(6x - 12)}{3} + 3x(4) = \frac{3x(18)}{x} \\ x(6x - 12) + 12x = 3(18)[/tex]
Expand:
[tex]x(6x) - x(12) + 12x = 54 \\ 6x^{2} - 12x + 12x = 54 \\[/tex]
Simplify:
[tex]6 {x}^{2} = 54[/tex]
Divide by 6 on both sides:
[tex] {x}^{2} = 9[/tex]
-9 on both sides:
[tex] {x}^{2} - 9 = 0[/tex]
Factorise:
*Since a²-b²= (a +b)(a -b),
[tex] {x}^{2} - {3}^{2} = 0 \\ (x + 3)(x - 3) = 0[/tex]
Thus,
x +3= 0 or x -3= 0
x= -3 or x= 3
Answer:
w = 3
Step-by-step explanation:
(6x-12)/3 + 4 = 18/x
Simplify fraction
2x -4 +4 = 18/x
Combine -4+4=0 Divide by 2 to reduce
x = 9/x
Multiply both sides by x
x² = 9
x = 3, -3

Answer:
x = 7/3
Step-by-step explanation:
3x - 2 =5
Add 2 to each side
3x-2+2 = 5+2
3x = 7
Divide by 3
3x/3 = 7/3
x = 7/3
Answer:
x = 7/3
Step-by-step explanation:
So there's 3 x's, two -1s and 5 +1s.
3x + (2 * -1) = (5 * 1)
Multiply 2 times -1 and 5 times 1.
3x - 2 = 5
Add 2 to both sides (to cancel out the minus 2.)
3x - 2 + 2 = 5 + 2
3x - 0 = 7
3x = 7
Now, divide both sides by 3 to get the x by itself (so you end up with x = something).
(3x)/3 = 7/3
3/3 simplifies to 1 so you end up with:
x = 7/3

Jackson receives 4.63 as his change at the grocery store. He places it into a charity donation jar at the register.
Write an addition equation to represent Jackson's net change in money.
Enter your answer as an addition equation, formatted like this: 42+(-53)=-11
Do not enter the dollar sign. Do not enter any units. Do not use spaces.
Answer:
M+4.63=T
Step-by-step explanation:
M represents the amount that he spent on his groceries. T is total
The addition equation to represent Jackson's net change in money is x + (-y) = 4.63.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
It is given that:
Jackson receives 4.63 as his change at the grocery store. He places it into a charity donation jar at the register.
Let x be the initial amount before purchase
Let y be the cost of the item purchased
Initial amount + cost of the item purchased = change received
The addition equation to represent Jackson's net change in money is:
x + (-y) = 4.63
Here y is with the negative sign because it is incurred
The change received = 4.63
Thus, the addition equation to represent Jackson's net change in money is x + (-y) = 4.63.
