Division first:
-2/5 / 8/15
When dividing two fractions flip
The second one over and multiply:
-2/5 x 15/8 = (-2x15)/(5x8) = -30/40 = -3/4
Now you have:
2-3/4-3/4
2-3/4 = 1 1/4
1 1/4 - 3/4 = 1/2
The answer is 1/2
A number x is decreased by 40% then increased by 25% what is the final result In terms of x ?
Answer:
Step-by-step explanation:
Let your number be X. To increase X by 40% we can multiply it by 1.4, let's call this new number Y.
So Y = X * 1.4
Now to decrease Y by 40% we can multiply it by 1 - .4 = .6. Lets call this new number C.
So C = Y *.6 = (X * 1.4) * .6 = X * (1.4 * .6) = X * .84.
Therefore, C = .84 * X.
So we can see C is 84% of X, or 16% less than X.
Thus, if you increase a number by 40% then decrease it by 40%, the net percentage is -16% .
Final result in terms of 'x' will be → 0.75x
Conversion of verbal statement to algebraic expression: Select the variables given in the verbal statement first. Form the algebraic expression as per verbal statement given in the question.
Let the number = x
As per first statement → "A number 'x' is decreased by 40%"
Algebraic expression for the statement → (x - 40% of x)
→ (x - 0.4x)
→ 0.6x
Second statement → "Then increased by 25%"
Algebraic expression for the statement → (0.6x + 25% of 0.6x)
→ [tex](0.6x+\frac{25}{100}\times 0.6x)[/tex]
→ [tex](0.6x+0.15x)[/tex]
→ [tex]0.75x[/tex]
Therefore, final result in terms of x will be (0.75x).

Hey there!!!!
Given,
Angle r and angle s are supplementary angle.
And angle r = 120°.
Now, we have,
supplementary angle's sum is always 180°.
So, angle r + angle s = 180°.
or, 120°+ angle s = 180°
Therefore the measure of angle s is 60°.

Consider the function g(x) = -3x - 4 if the domain value is selected from the set {-8, -2, 0, 3}, which of the following is a corresponding range value?
A. 18
B. -10
C. -13
D. -5
Answer:
C. -13
Step-by-step explanation:
Solve for g(x) by replacing x with each domain value in the set. Solving for g(x) will give you these numbers:
{20, 2, -4, -13}
-13 is the only value that appears in the range set and in the multiple choice solutions. Therefore, the answer is C. -13
C. [tex]-13[/tex] is a corresponding range value.
The domain of a function refers to the set of all values for which the function is defined.
The range is the set of all values that function takes for the given values of domain.
Domain is [tex]\boldsymbol{\left \{ -8,-2,0,3 \right \}}[/tex]
[tex]g(x)=-3x-4[/tex]
[tex]g(-8)=-3(-8)-4[/tex]
[tex]=20[/tex]
[tex]g(-2)=-3(-2)-4[/tex]
[tex]=2[/tex]
[tex]g(0)=-3(0)-4[/tex]
[tex]=-4[/tex]
[tex]g(3)=-3(3)-4[/tex]
[tex]=-13[/tex]
Range is [tex]\boldsymbol{\left \{ 20,2,-4,-13 \right \}}[/tex]
So, [tex]\boldsymbol{-13}[/tex] is a corresponding range value.

Bonnie ran a total of 18 miles over the course of 2 track practices. How many miles would Bonnie have run after 7 track practices? Solve using unit rates.
Answer:
63 miles
Step-by-step explanation:
Bonnie ran a total of 18 miles over the course of 2 track practices. How many miles would Bonnie have run after 7 track practices?
2 track practices = 18 miles
7 track practices = y miles
Cross Multiply
2 track practices × y miles = 18 miles × 7 track practices
y miles = 18 miles × 7 track practices/ 2 track practices
y miles = 63 miles.
Therefore, Bonnie will have run 63 miles after 7 track practices

For question 2 the slope is 1. So what you do is get the points you need to put on the graph and move them up one. Like how you did on question 1.
(0.5, 5) (1, 10) (1.5, 15) (2, 20) (2.5, 25)
Question 3 is the same thing but the slope is now 2. Then you would have to pin the points as...
(1, 2) (2, 4) (3, 6) (4, 8) (5, 10)
