Answer:
2 1/2 + (-1/3) = 2 1/6
Step-by-step explanation:
Adding a negative number is the same as subtracting the opposite of it, so you get:
2 1/2 - 1/3
Then you need to convert them to the same denominator by using GCM (Greatest Common Multiple), getting:
2 3/6 - 2/6
Then, you subtract 2/6 from 3/6, getting:
2 1/6
Answer:
ur answer is 3
Step-by-step explanation:
because when ya think about it 1/2 and 1/3 are the same thing just 3 is teenie smaller
Diane walks 5 , 000 steps each day for exercise. Over the next year, her goal is to increase the number of steps she walks each day by 10 . Let f ( x ) represent the number of steps Diane plans to walk on day x since beginning her goal. What does f ( 100 ) = 6 , 000 represent? Select from the drop-down menus to correctly complete the sentence. Diane plans to walk steps on day since beginning her goal.
Answer:
Diane plans to walk [6,000] steps on day [100] since beginning her goal.
Step-by-step explanation:
10 x 100 = 1,000
5,000 + 1,000 = 6,000
100 days after adding 10 steps each day results in 6,000 steps

on a car.
• Create a model in standard form to represent this linear relationship.
• Identify the x-intercept. Explain what this means in the context of the problem.
• Identify the y-intercept. Explain what this means in the context of the problem.
Identify two combinations that are solutions to this equation. Explain what these combinations mean in the
context of the problem.
Answer:
Step-by-step explanation:
- 25x + 15y = 750
- (30, 0) are coordinates of x-intercept. If there is no pool-cleaning job student has to do 30 lawn-mowing.
- (0, 50) are coordinates of y-intercept. If there is no lawn-mowing job student has to do 50 pool-cleanings.
- ( 15 , 25 ) mean 15 lawn-mowing and 25 pool-cleanings
$25(15) + $15(25) = $750
$375 + $375 = $750

A fruit jucie company includes 1.231 ounce of apple jucie in 6.65- ounces bottel of a mixied fruit jucie. How much of the bottel of mixied fruit jucie is NOT apple jucie? THANK YOU!
Answer: 81.49% of bottle of mixed fruit juice is NOT apple juice.
Step-by-step explanation:
Quantity of mixed fruit juice = 6.65 ounces
Quantity of apple juice in it = 1.231 ounce
Quantity of mixed fruit juice is NOT apple juice = (6.65-1.231) ounces
= 5.419 ounces
Fraction of bottle is not apple juice = [tex]\dfrac{5.419}{6.65}\approx0.8149=81.49\%[/tex]
Hence, 81.49% of bottle of mixed fruit juice is NOT apple juice.

Write the equation of the line fully simplified slope-intercept form.
Answer:
The equation of the line is y = -x + 8
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slope of the lineb is the y-intercept (value y at x = 0)The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the lineFrom the given figure
∵ The line passes through points (8, 0) and (0, 8)
∴ x1 = 8 and y1 = 0
∴ x2 = 0 and y2 = 8
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{8-0}{0-8}=\frac{8}{-8}=-1[/tex]
∴ m = -1
→ Substitute it in the form of the equation above
∵ y = -1(x) + b
∴ y = -x + b
∵ b is value y at x = 0
∵ At x = 0, y = 8
∴ b = 8
→ Substitute it in the equation above
∴ y = -x + 8
∴ The equation of the line is y = -x + 8
the graph below shows a quadratic function f(x) and an absolute value function g(x)
which of the following x-values are approximate solutions to the equation f(x)=g(x)? select all that apply
Answer:
The x-values that are approximate solution of the equation [tex]f(x) = g(x)[/tex] are [tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex], respectively.
Step-by-step explanation:
From graph we infer that the x-values that represents a solution to the system of equations corresponds to those values of x in which both functions coincide. As we see, there are two x-values for [tex]f(x) = g(x)[/tex], which are described below:
[tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex]
The x-values that are approximate solution of the equation [tex]f(x) = g(x)[/tex] are [tex]x_{1} \approx -3.5[/tex] and [tex]x_{2}\approx 5[/tex], respectively.

Why does multiplying the input of a linear function change
only the slope while multiplying the output changes both the slope and the
y-intercept?
Answer:
Step-by-step explanation:
If we have a linear function and we multiply the input of the function, we aren't really changing the values of the function, we're changing the rate at which those values are reached.
E.g. if you look at the attached picture, we have [tex]f(x) = 2x[/tex] and [tex]f_2(x) = 4x[/tex], which is just [tex]f(2x)[/tex]. The value when the red line is x = 1 is half that of the value of the blue line when x = 1.
The values of the f(2x) line are reaching the values of f(x) twice as fast, meaning it has a slope of twice as much. However, it still grows through the same intercept.
If you're interested in the calculus behind this, look up the chain rule of derivatives.
However, when you start changing the output of the function, you're changing the entire equation. It's not the same line anymore.
4 ice cream cones cost $6. At this rate, how much do 7 ice cream cones cost?
this is a test for middle schoolers but anyone is free to answer
Answer:
$42
Step-by-step explanation:
Equation: y = 6x
x = number of ice cream cones
y = 6(7) = 42
Hi! I believe your answer is $10.50. If it's $6 for 4 ice cream cones, divide 6 by 4 and you'll get 1.5, or $1.50 per ice cream cone. For 7 ice cream cones, multiply the unit rate ($1.50 per ice cream cone) by 7. The total cost is $10.50. I hope this helps you! Good luck and have a great day. ❤️✨

In ΔRST, \text{m}\angle R = (11x+3)^{\circ}m∠R=(11x+3) ∘ , \text{m}\angle S = (x+15)^{\circ}m∠S=(x+15) ∘ , and \text{m}\angle T = (2x+8)^{\circ}m∠T=(2x+8) ∘ . Find \text{m}\angle R.M∠R.
Answer:
<R = 124°
Step-by-step explanation:
Note that the sum of angles in a triangle is 180degrees. In a triangle RST
Given
∠R=(11x+3)°
∠S=(x+15)°
∠T=(2x+8)°
Required
∠R
First we need to get the value of x;
since <R+<S+<T = 180
11x+3+x+15+2x+8 = 180
11x+x+2x+3+15+8 = 180
14x+26 = 180
14x = 180-26
14x = 154
x = 154/14
x = 11°
get <R
Since <R = 11x+3
<R = 11(11)+3
<R = 121+3
<R = 124°
Hence the measure of <R is 124°
