Answer:
B. -3/2 +1/5
Step-by-step explanation:
The distributive property lets you multiply each of the inside terms by the outside factor.
(-1/2)(3 -2/5) = (-1/2)(3) +(-1/2)(-2/5)
= -3/2 +1/5
A study of a population of 1,200 frogs revealed that 12 out of every 180 frogs in the population have spots on their back. Based on the results of this study, how many frogs do not have spots on their back? Explain.
Answer:
80 spotted frogs
Step-by-step explanation:
We can write a ratio
spotted frogs:frogs
12:180
x:1200
To solve we just multiply 12*6.66667 (because this is what we multiplied 180 to get to 1200)
the answer is 80

7z2−38z+15 Select the factors of this quadratic expression.
Answer:
(7z-3)(z-5)
Step-by-step explanation:
7z^2-38z+15
(7z-3)(z-5)
Answer:
(z - 5)(7z - 3)
Step-by-step explanation:
Given
7z² - 38z + 15
Consider the product of the factors of the coefficient of the z² term and the constant term which sum to give the coefficient of the z- term
product = 7 × 15 = 105 and sum = - 38
The factors are - 35 and - 3
Use these factors to split the z- term
7z² - 35z - 3z + 15 ( factor the first/second and third/fourth terms )
= 7z(z - 5) - 3(z - 5) ← factor out (z - 5) from each term
= (z - 5)(7z - 3) ← in factored form

solve . 15 - 10x = 5(x + 9) show your work
Answer:
x= -2
Step-by-step explanation:
Let's solve your equation step-by-step.
15−10x=5(x+9)
Step 1: Simplify both sides of the equation.
15−10x=5(x+9)
15+−10x=(5)(x)+(5)(9)(Distribute)
15+−10x=5x+45
−10x+15=5x+45
Step 2: Subtract 5x from both sides.
−10x+15−5x=5x+45−5x
−15x+15=45
Step 3: Subtract 15 from both sides.
−15x+15−15=45−15
−15x=30
Step 4: Divide both sides by -15.
−15x/-15 = 30/ -15
x= −2
5x + 2 – 2(x - 1) = 3x + 4
PLS HELP !
Answer:
5x + 2 - 2(x - 1) = 3x + 4
⇔ 5x + 2 - 2x + 2 = 3x + 4
⇔ 3x + 4 = 3x + 4
⇔ 4 = 4
⇒ infinite solutions

"solve for X" any help would be appreciated thankss
Answer:
180° on a straight line
180 = 18x - 54
add 54 to both sides
234 = 18x
X = 234/18
X= 13°
6 X 13 - 5 = 73
12 X 13 - 49 = 107
107 + 73 = 180

Complete the solution of the equation. Find the
value of y when x equals 15.
-3x - y = -51
Answer:
The solution of the equation y = 36
Step-by-step explanation:
Explanation:-
Given equation -3x-y =-51
Given that x =15 in equation -3x-y=-51
⇒ - 3(15) - y = -51
⇒ - 15 - y =-51
⇒ -15+ 51 = y
⇒ y = 36

Answer:
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = 0 x² + 6 x + 20
Step-by-step explanation:
Step(i):-
Given that the length of the rectangle = 2x +3
Given that the width of the rectangle = x +7
Perimeter of the rectangle = 2(length + width)
Step(ii):-
Perimeter of the rectangle = 2(length + width)
= 2(2 x +3 + x+7)
= 4x +6+2x+14
= 6 x +20
Final answer:-
Perimeter of the rectangle = 6 x +20
Perimeter of the rectangle = o x² + 6 x + 20

3/5x - 7 = 23
A. x = 40
B. x = 45
C. x = 50
D. x = 55
Answer:
(C) x=50
Step-by-step explanation:
[tex]\frac{3}{5 }x -7=23[/tex]
[tex]\frac{3x}{5} -7=23[/tex]
[tex]\frac{3x}{5} -7+7=23+7[/tex]
[tex]\frac{3x}{5}=30[/tex]
[tex]3x=30* 5[/tex]
[tex]3x=150[/tex]
[tex]x=50[/tex]
Answer:
(C) X = 50
Step-by-step explanation:
(3/5)*x-7 = 23 // - 23
(3/5)*x-23-7 = 0
3/5*x-30 = 0 // + 30
3/5*x = 30 // : 3/5
x = 30/3/5
x = 50 (Sorry if it's wrong)
How can you check to see if two ratios form a proportion? Explain the method you used to find the answer to the previous problem.
Answer:
Step-by-step explanation:
A proportion is simply a statement that two ratios are equal. In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
Answer:
Write a proportion using the ratios. Find the cross products. If the cross products are equal, then the ratios form a proportion.
