Answer:
-2 5/9
Step-by-step explanation:
w +(-x) -2/3 = w -x -2/3 = -5/9 -4/3 -2/3
= -(5/9 +4/3 +2/3) = -(5/9 +(4+2)/3) = -(5/9 +2)
= -2 5/9

Nerissa has 5 pink bows, 1 blue bow, and 4 purple bows in a box. She will randomly choose 1 bow from the box.
What is the probability Nerissa will choose a purple bow?
Answer:
the answer would be 4/10 but the simplified version would be 2/5.
Step-by-step explanation:
add up how many bows you have, that will be the denominator. Then, the numerator is the number of purple bows. and if your going to simplify it divide the numerator and denominator by 2.
Answer:
fraction wise(4/10 chance)
percent wise:(40% chance)
Step-by-step explanation:
(There are 2 options) First add all of the bows then see how many purple bows there are. Since there are 4 bows it would be 4/10 or 40%.

Which equation represents the line shown on the coordinate right below
Answer:
A
Step-by-step explanation:
9514 1404 393
Answer:
A
Step-by-step explanation:
The line has positive slope (rises to the right) and a y-intercept of -2. The only matching choice is A.
__
Each of the equations is in slope-intercept form:
y = mx + b . . . . . where m is the slope and b is the y-intercept
So, you need to choose the one that has m > 0 and b = -2.

The high school athletics department is installing a new rectangular addition to their current practice field. The length of the new addition will be at least 10 meters more than twice the width of the new addition. The original field has an area of 300 square meters. The area of the entire practice field, with the addition, must be no more than 1,200 square meters.
If A represents the area of the entire practice field, including the new addition, and x represents the width of the new addition, in meters, which system of inequalities can be used to represent this situation?
Answer:
the answer is D
Step-by-step explanation:
The system of inequalities that best represents this situation provided A denotes the area of the entire field is: [tex]\mathbf{\left \{ {{A\geq 2x^2+10x+300 } \atop {A \leq 1200}} \right. }[/tex]
What are word problems?Word problems in mathematics are ways we can use variables, algebra notations, and arithmetic operations to solve real-life cases.
From the given information;
We have a new addition to the current rectangular field,
Let that new addition to the current rectangular field be xThe length of the new addition = 10xTwice the width of the new addition = 2x²The original area of the field = 300From the above information, we can derive a quadratic equation:
2x² + 10x + 300Also, we are given a constraint that the entire area of the practice field should be no more than 1200. i.e. It can be less than 1200 or equal to 1200.
Thus, the system of inequalities that best represents this situation provided A denotes the area of the entire field is:
[tex]\mathbf{\left \{ {{A\geq 2x^2+10x+300 } \atop {A \leq 1200}} \right. }[/tex]

Sin(x) = 15/24 = 0.625
x = sin-1(0.625)
x = 38.68
Two

Which statement is best supported by the information in the chart?
Object 1 is the heaviest object.
Object 3 is heavier than Object 1.
The weight is heavier than Object 2.

Answer:
Object 1 is the heaviest object.
Step-by-step explanation:
The first column of the table tells you ...
Object 1 is heavier than the 10 kg weight
The second column of the table tells you ...
Object 2 weighs 10 kg
The third column of the table tells you ...
Object 3 is lighter than the 10 kg weight
Then the relative weights are ...
Object 1 > Object 2 > Object 3
That is, Object 1 is the heaviest object.

4/5 w+13=25 please show work
Answer:
w=15
Step-by-step explanation:
4/5*w+13-(25)=0
STEP 1
4
Simplify —
5
Equation at the end of step1
4
((— • w) + 13) - 25 = 0
5
2.1 Adding a whole to a fraction
Rewrite the whole as a fraction using 5 as the denominator :
13 13 • 5
13 = —— = ——————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
4w + 13 • 5 4w + 65
——————————— = ———————
5 5
Equation at the end of step2
(4w + 65)
————————— - 25 = 0

STEP 3
Rewriting the whole as an Equivalent Fraction :
3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
25 25 • 5
25 = —— = ——————
1 5
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
(4w+65) - (25 • 5) 4w - 60
—————————————————— = ———————
5 5
STEP4
Pulling out like terms :
4.1 Pull out like factors :

When a fraction equals zero :
5.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
4•(w-15)
———————— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
4 • (w-15) = 0
Equations which are never true:
5.2 Solve : 4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
5.3 Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15

Horizontal and parallel lines e and f are cut by transversal b. At the intersection of lines b and e, the uppercase right angle is (2 x + 18) degrees. At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees and the bottom right angle is y degrees. What is the value of y? 16 50 130 164
Answer:
130
Step-by-step explanation:
From the FIQURE of the question, we can see that line "e" is parallel to line "f" then we can say (2x + 18)=( 4x - 14)
Then we can collect like terms
2x-4x= -14-18
-2x=-32
The negatives cancelled out we have
x = 16
From the question, At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees
Angle on a straight line is 180° then we can calculate "y" as
y = 180 - (4x - 14)
= 180-4x+14
= 180+14-4x
But x= 16, then substitute we have
= 180 +14 - 14(16)
= 130
Hence, the value of y is 130

∘
. Find \text{m}\angle KLM.m∠KLM.
9514 1404 393
Answer:
48°
Step-by-step explanation:
Exterior angle KLM is equal to the sum of the remote interior angles.
∠KLM = ∠LJK + ∠JKL
(8x -16)° = (2x +2)° +(3x +6)°
8x -16 = 5x +8 . . . . . . . . . . divide by °, collect terms
3x = 24 . . . . . . . . . . add 16-5x
x = 8 . . . . . . . . divide by 3
The measure of the angle of interest is ...
∠KLM = (8x-16)° = (8·8 -16)°
∠KLM = 48°
