-2/3 x - 1 =19 yeah its -2over3 with x to the right then -1 = 19
Answer:
x = 30
Step-by-step explanation:
Given the expression
-2/3 x - 1 =19
We are to find the value of x
Add 1 to both sides
2/3 x -1 +1 = 19+1
2/3 x =20
Multiply
2/3x × 3 = 20×3
2x = 60
x = 60/2
x = 30.
Hence the value of x is 30

How many terms are there in each expression? a. 9x − 4y + 7z − 8w + t b. Ab + 3a − 4b c. 25a + 9bc − 8def
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.
Charles has 24 marbles. He has 6 more yellow marbles than blue marbles.
Which equation represents this situation?
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
Jam is made from sugar and strawberries in the ratio of 3:5 A jar contains 150g of sugar how many grams of strawberries are in the jar
Answer:250
Step-by-step explanation:
150/3 =50
50x5=250
The quantity of strawberries in jar is 250 gram.
What is the ratio?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.

in training to run a half marathon, jenny ran 2/5 hours on tuesday, 1 1/6 hours on thursday, and 2 1/15 on Saturday. what is the total amount of hours that jenny ran this week? (simplify your answer and state it as a MIXED NUMBER)
9514 1404 393
Answer:
3 19/30 hours
Step-by-step explanation:
The given fractions will have 30 as a common denominator.
12/30 + 1 5/30 + 2 2/30 = (1 +2) +(12 +5 +2)/30 = 3 19/30 . . . hours
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.

The sixth-graders at Jen's school got to choose between a field trip to a museum and a field trip to a factory. 57 sixth-graders picked the museum and 38 sixth-graders picked the factory. What percentage of the sixth-graders picked the museum?
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.
What is the percentage?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%.

The bearing of Measham from Tamworth is 052°
Calculate the bearing of Tamworth from Measham.
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.

Find the slope of the line that passes through (10, 7) and (1,8).
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

Tommy and Mark earned a total of $88.00 raking leaves for Mrs. Bopp. Tommy raked for 5 hours and Mark raked for 3 hours. If the boys were paid the same rate, how much did Tommy earn?
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

What is an equation of the line that passes through the points (4, -5) and (2, 0)?
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
