ONE STEP EQUATION :
1. When solving the equation -2x = 14; how would you solve for x? What would x equal?
2. When solving the equation 7 + x = -3; how would you solve for x? What would x equal?
3. When solving the equation x/5 = -4; how would you solve for x? What would x equal?
Answer:
Question one X=-7 because -2 x -7 = 14
Question two X= -10 because -3 - -10=7
Question three X =-20 because -4 divided by-20
Step-by-step explanation:
i need help with this question please
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Jeff worked 4 2/3 hours in the morning and 3 3/4 hours in the afternoon. How many total hours did he work today?
7 5/7 hours
7 5/12 hours
8 5/12 hours
8 1/2 hours
Answer:If you would like to know how many total hours did Jeff work today, you can calculate this using the following steps:
4 2/3 hours in the morning + 3 3/4 hours in the afternoon = 4 2/3 + 3 3/4 = 14/3 + 15/4 = 56/12 + 45/12 = (56 + 45) / 12 = 101/12 = 8 5/12 hours
Jeff worked 8 5/12 hours in total.

Of the 120 math tests, 47 were Bs. What percent of the math tests were Bs? Round to the nearest whole percent.
Answer:
39.17%
Step-by-step explanation:
Answer:
39%
Step-by-step explanation:
Percent is ALWAYS out of 100, and the unknown is percent so our first part of the equation will be %/100. Now our second part of equation: is/of
Of represets whole the total, and we have our key word “Of the 120 math tests”. We have our total: 120; 47 is our part so second part of equation: 47/120.
Our equation so far: %/100 = 47/120 now we need to multiply the numbers that we have diagonally: 100% x 47; 47/100 we’re multiplying so we’ll move two 0s to the right. Answer: 4700
Now, we’ll divide 4700 by 120. 4700/120. Answer: 39.1666666667. Round to nearest whole means round to nearest ones.
Thus, the answer is 39.

Drag each expression to show whether it is equivalent to 4 × 5 or to 2 × 4 × 5.
Answer:
1st one: 4x5x2: in the 2nd box
2nd one: (4x2)+(4x3) : in the 1st box
3rd one: 2x(4x5): in the 2nd box
Last one: 4x(1+4): in the 1st box
Step-by-step explanation:
For the first one: 4x5x2, you can multiply any 2 numbers together example- you can multiply 4x5, 5x2, 4x2 then multiply the third digit I did 4x5=(20) x2= 40.. 5x2 =10 x4=40.. see they'll all end up to 40.
For the second one: (4x2)=8 (4x3)=12 add 8 and 12 it'll equal 20
For the third one: 2x(4x5) start by multiplying 4 and 5 which is 20, then multiply 20 by 2 =40
For the fourth one: 4x(1+4) 1+4=5, multiply 5 by 4 and get 20
The first box equals 40, the second box equals 20
And always remember to answer the problem in the parenthesis first, then continue with the rest of the problem. Hope this helps!! And I hope I didn't confuse any of you.. Let me know if you have any questions or if I made a mistake somewhere but besides all that have a great day! :)
4 × 5 equivalent to (4×2) + (4×3) and 4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and 2(4×5)
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 ÷.
= 4×5×2 = 40
=(4×2) + (4×3) = 8+12 = 20
= 2(4×5) = 40
= 4(1+4) = 4(5) = 20
We have:
4 × 5 = 20 2 × 4 × 5 = 40
(4×2) + (4×3) 4×5×2
4(1+4) 2(4×5)
Thus, 4 × 5 equivalent to (4×2) + (4×3) and 4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and 2(4×5)

Explain how you can tell whether a group of ratios represents a proportional relationship.
Answer:
To see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.
(Hope this helps!! Btw, I am the first to answer.)
A group of ratios represents a proportional relationship. When the connection is proportional if the ratio remains constant. Explanation is given.
What is proportional relationship?A proportional relationship is a relationship between two expressions and where changes in one expression means some constant change in the other expression as well. Generally, it is represented as x/y = k, where x and y are two expressions and k is constant.
Ratio:
The numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.
An ordered pair of integers a and b,
represented as a / b, is a ratio if b is not equal to 0.
A proportion is an equation that sets two ratios at the same value.
The ratios between the two variables should be considered in order to determine whether a relationship is proportional.
The connection is proportional if the ratio remains constant.
Therefore, the relationship is proportional if the ratio remains constant.
