Answers

Answer 1

Answer:

300 + r = 217

Step-by-step explanation:

300 -> 300

added to r -> +

is the same as -> =

217 -> 217

Put this in one equation and you get:

300 + r = 217

If you need to solve for r (need to isolate r to solve for r):

300 + r = 217

r = 217 / (-300)

r = -0.723333333

Answer 2

You are right 300+r=217

1) Write an equation that can be used to solve for the missing angles. (5pts)

2) Then Solve the equation for find the value of X. (Make sure to explain or show all the steps to get full Credit)

Answers

I don’t know how I should find the missing angles. But I can solve for X. So first we need to combine like terms so we add 2x, x and x which gives us 4x. And we set up our problem like this: 4x + 24=180. So we then subtract 24 from 180 and get 156 then divide 4x and 156, which leaves us with x=39

Step-by-step explanation:

What i did was i did it in standard form. But, what i did was the 7 x 2 which is 14 then carried the 1 to the ones place. Then, i did 7x2 + 1 to get 15. Then, i did 0 x 2 and 2 x 0 to get 0, then i added and moved the decimal from 2.2 one time to make it 15.4. To check my work, i did 15.4 divided by 7 to get 2.2.

n = 7.75

n=2.125

n= -7.75

n=-2.125

Answers

The answer is n= 7.75.

Answer:

n=-7.75

Step-by-step explanation:

Based on the given conditions, formulate: 5.5+2×X=-10

Rearrange unknown terms to the left side of the equation:2x=-10-5.5

Calculate the sum or difference:2x=-15.5

Divide both sides of the equation by the coefficient of variable:x=-15.5/2

Multiply both the numerator and denominator with the same integer:-155/20

Cross out the common factor:-31/4

get the result: -7.75

Answer: -7.75

Answers

Answer:

→ Last year, there were m pies baked for the bake sale. This year, there were 215 pies baked. Using m , write an expression for the total number of pies baked in the two years.

Step-by-step explanation:

▶ Given :-

→ Last year, number of pies baked for bake sale = m.

→ This year, number of pies baked for bake sale = 215 .

▶ To find :-

→ The equation that represents the total number of pies baked for bake sale .

▶ Solution :-

→ Let the total number of pies baked for bake sale in two years be ‘x’ .

And, last year no. of pies baked = m [ given ] .

Therefore, the equation that represents the total number of pies baked for bake sale :-

→ x = m + 215 .

✔✔ Hence, it is solved ✅✅.

All you need to do is 124 divided by 2 and your answer is /equal to (m)

ASAP!!! A proportional relationship is shown in the table below. X: 0 0.3 0.6 0.9 1.2 Y: 0 1 2 3 4 What is the slope of the line that represents this relationship? Graph the line that represents this relationship.

Answers

The slope is 3/10, and just graph 2 points ( so like .3,1 and .9,2) and just use Desmos to figure out the line using the y=3/10x+3.64 and just type it in

the slope is 0 if it goes across

For questions #9 - 11 "finding the slope" of a linear (straight) line, recall the "tools" that we can use:

1) Given a Graph: Slope or "m" = rise/run from one (x, y) point to a second (x, y) point on the line

2) Given any two (x, y) points on the line: Slope or "m" = y2 - y1 / x2 - x1

3) Given a "Table of Values": Choose any two (x, y) points in the table, then calculate the slope using the slope formula - Slope or "m" = y2 - y1 / x2 - x1
