D on edg

Step-by-step explanation:

Answer:

a. 5

b. 3

c. 3

Step-by-step explanation:

Terms are variables, the number connected to the term is called the coefficient, the variable does not need a coefficient to be considered a term. There are 5 terms in a (9x,4y,7x,8w,t) 3 terms in b (Ab,3a,4b) and 3 terms in c (25a,9bc,8def).

Notice how there are multiple variables in sets b and c. Do not get confused into thinking these are multiple terms, they are one. A term is a single expression with one or more variables that are multiplied but never added or subtracted. Ex: abc is one term but 3 variables.

Answer:

Tommy earned $55

Step-by-step explanation:

Proportions

Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.

The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.

Tommy raked 5 hours, so he earned 5*$11 = $55

Tommy earned $55

Answer:

 4.50

Step-by-step explanation:

4 = Whole number. 1 = Numerator. 2 = Denominator. To get 4 1/2 in decimal form, we basically convert the mixed number to a fraction and then we divide the numerator of the fraction by the denominator of the fraction.

The decimal form of  4 and 1/2  is 4.5

Decimal is a fraction written in a unique form. The dot notation is used to represent the fraction form.

Therefore, 4 and 1/2 in decimal form is represented as follows;

Mixed fraction = 4  1 / 2

Improper fraction = 9 / 2

decimal form of  1 / 2 = 0.5

Therefore, 4 1 / 2 = 4.5

Answer:

The slope is: -1/9

Answer:

-1/9

Step-by-step explanation:

You have 2 points, (x1, y1) and (x2, y2). To find slope, do (y2-y1)/(x2-x1)

(10, 7) and (1, 8)

slope is

(8 - 7)/(1 - 10)

= 1/-9

= -1/9

Answer:

232°

Step-by-step explanation:

1. 180-52=128

2. 360-128=232

first you subtract 52 from 180 bc you have to get the angle not included for calculating the whole bearing bc the starting point is the north line. so everything before the north line is not valid bc when you're calculating an angle like this you go from lef to to right, clockwise. in every calculation of bearings you go clockwise. next you just subtract the product you got from 360 and that's it.

The quantity of strawberries in jar is 250 gram.

Comparing two amounts of the same units and determining the ratio tells us how much of one quantity is in the other. Two categories can be used to categorise ratios. Part to whole ratio is one, and part to part ratio is the other. The part-to-part ratio shows the relationship between two separate entities or groupings.

Given the Jam is made from sugar and strawberries in a ratio of 3:5,

ratio of sugar to strawberries = 3/5

sugar in jam = 150 gram

let quantity of strawberries  be x gram

the ratio of sugar to strawberries = 150/x

since both ratios are in proportions so

3/5 = 150/x

x = 150 * 5/3

x = 250 gram

Hence the quantity of strawberries is 250 grams.

THANK YOU.

Answer:

y = - [tex]\frac{5}{2}[/tex] x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (2, 0)

m = [tex]\frac{0+5}{2-4}[/tex] = [tex]\frac{5}{-2}[/tex] = - [tex]\frac{5}{2}[/tex] , then

y = - [tex]\frac{5}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, 0 )

0 = - 5 + c ⇒ c = 0 + 5 = 5

y = - [tex]\frac{5}{2}[/tex] x + 5 ← equation of line

Answer:

Step one- Divide both sides by 2

Step two- Add three to both sides

Step three- Divide both sides by 6

Answer:

y = x + (6+x)

Step-by-step explanation:

Y represents the total number of marbles.

X represents number of blue marbles.

6+X represents number of yellow marbles.

To Solve:

  24 = 2x + 6

  Subtract 6 from both sides: 18 = 2x

  Divide boths sides by 2: 9 = x

Now fill in the values: Blue Marbles = 9, Yellow marbles = 15

Answer:

60% choose the Museum.

Step-by-step explanation:

Add the students who choose the museum and the students who choose the factory to get 95. You would then need to divide the amount of students who choose the museum by the total amount of students. Your answer would be 0.6, or 60%

60% of the students sixth-graders at Jen's school picked the museum.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, 57 sixth graders picked the museum and 38 sixth graders picked the factory.

So, the total no. of students is (57 + 38) = 95.

∴ The percentage of the sixth-graders who picked the museum is,

=  (57/95)×100%.

= 60%.

Jenny ran 3 19/30 hours this week.

Answer:

Step-by-step explanation:

Total hours that Jenny ran = 3.63 hours.

Step-by-step explanation:

Jenny ran on Tuesday for = 2/5 hours or 0.4 hours.

Time consumed to run on Thursday = 11/6 hours or 1.83 hours.

Time consumed to run on Saturday = 21/ 15 hours or 1.4 hours.

Here, the total hours can be calculated by just adding all the running hours. So the running hours of Tuesday, Thursday, and Saturday will be added to find the total hours.

Total hours that Jenny ran = 0.4 + 1.83 + 1.4 = 3.63 hours.
