Answer:
C
Step-by-step explanation:
First of all -2-5= -7
It isn't (A) because (A) is saying that the beginning temperature was a postive number, which it wasn't The beginning temperature is -2, which is negative. So we can cross that off.
It isn't (B) because (B) is saying that you start off with -2 and then it gets warmer, and temperature adds up onto it. When you do -2 +5, you get 3, which is not the answer.
So, the answer is c
Proof: It starts of with negative 2, which is the first temperature. Then, it says decreased by 5, which is what is happening. 5 is getting subtracted from -2
So, the answer is C
Answer:
C
Step-by-step explanation:
-2-5
the minus sign infront of the two has to stay with the two so we would have -2°C the options we would be left with are b and c but since it says subtract 5 that would be a decreases not an increase so it would be decrease 5°C

The figure below shows a rectangular prism and a cube:
A rectangular prism and a cube are drawn side by side. The length of the rectangle prism is 5 inches, the width is 4 over 5 inch, and its height is 1 and 3 over 5 inches. The cube has a side length of 1 over 5 inch.
How many such cubes are required to completely pack the prism without any gap or overlap?
Answers
Answer:
Calculate the volume of each shape.
Volume of rectangle = 6 x 5/6 x 1 2/6 = 6 2/3 cubic inches.
Volume of cube = 1/6 x 1/6 x 1/6 = 1/216 cubic inch.
Now divide the volume of the rectangle by the volume of the cube:
6 2/3 / 1/216 = 1440
It will take 1.440 cubes to fill the rectangle.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 8 = 32. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - nine quarters minus eleven eighths is seven eighths.
Which of the following expressions are equivalent to minus, start fraction, 2, divided by, minus, 13, end fraction?
I will give Brainliest to whoever answers the best!
Answers
Answer:
Step-by-step explanation: The equivalent expression will be (-2)/ (-13) and-(-2/13) so option (A) and option (B) both will be correct. In such a fraction, the value that appears above the horizontal line is referred to as the numerator. It represents the number of pieces removed from the whole.
The denominator of a fraction is the numerical value that comes before the brings together various.
If we divide two numbers by each other than the upper word is called the numerator, and a lower word is called the denominator. For example, a fraction 1/5 here 1 will be the numerator and 5 will be denominated.
Given that now since the multiplication of - and - quantity is always positive so - and - is positive so it will be 2/13
If you take both options A and B in both options, the negative sign is going to be canceled and it will give a positive value.
Hence "The equivalent expression will be (-2)/ (-13) and-(-2/13)".
The denominator of a fraction is the numerical value that comes before the brings together various.

Answer:
1: $3.21.
2: 50x+120=300
3: h=5/7/ first step would be to adding 7 to both sides.
Step-by-step explanation:
for the 3rd:
you're combining like terms so you have to subtract 7 from both sides you gotta subtract 12-7 so that gives you 5=7h+7-7 and the subtract the 7-7, and that will give you 0 so you have 5=7h left.divide both sides by the same terms (7), so you'll have 5/7 and 7h/7 so 7/7=0 so you drop that and just have the h. now switch sides with the virable and the fraction you still have (5/7)you now have h=5/7.I NEED ANSWERS QUICKLY PLEASE HELP!!!

Jason wants to plant 66 carrot seeds and 44 onion bulbs. He would like to plant them so
that there are the same number of plants in each row and each row only has one type of plant. a. What is the greatest number of plants he can have in each row? SHOW YOUR
WORK
Answers
Answer:
Step-by-step explanation:
Since we need an equal amount plants in each row, you have to find the greatest common factor (GCF) of 66 and 44.
The factors of 44 are: 1, 2, 4, 11, 22, 44
The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66
Therefore, the greatest factor of 66 and 44 is 22. This means Jason will have 3 rows of carrot plants and 2 rows of onion plants. Each row will have 22 plants.
Jason can have a maximum of 22 plants in each row. This allows him to place 22 onion bulbs or 22 carrot seeds in each row.
We need to determine the greatest common divisor (GCD) of 66 and 44 to determine the maximum number of plants Jason can have in each row while still adhering to the requirements of having the same number of plants in each row and each row having only one type of plant.
The GCD denotes the maximum number of plants he is permitted to place in each row.
Using the Euclidean algorithm to find the GCD:
1. Divide the larger number by the smaller number:
66 ÷ 44 = 1 with a remainder of 22.
2. Divide the smaller number 44 by the remainder 22: 44 ÷ 22 = 2 with no remainder.
3. Since there is no remainder, the GCD is the divisor in the last division, which is 22.

3x + 5 = -9x + 29
2) Subtract 5 from both sides
3x + 5 - 5 = -9x + 29 - 5
