Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, distribute. 12r + 16 = -16r - 40
Then get r on one side by adding 16r to both sides then subtracting 16 from both sides. 28r = -56
Finally, divide by 28 on both sides to get r by itself.
r = -2

Sally spent $14.85 to buy 13 flowers. She bought lilies, which cost $1.25 each, and tulips, which cost $0.90 each. How many of each flower did Sally buy?
CAN SOMEONE HELP ME WITH THIS ONE PLEASE!!!!!!!
a = lilies
13 - a = tulips
We have: 1.25a + 0.90(13 - a) = 14.85
=> 1.25a + 11.7 -0.90a = 14.85
=> 0.35a = 14.85 - 11.7 = 3.15
=> a = 3.15 ÷ 0.35 = 9
=> She bought 9 lilies and 4 tulips

Answer:
5x^3 + 6x^2 + 14z
Step-by-step explanation:
When combining like terms with exponents, you just add them together as long as they have the same exponent. 3x^3 + 2x^3 = 5x^3
9z+5z=14z
6x^2 has no like terms.

Convert 6 ounces into grams. Round your answer to the nearest whole
number.
Answer:
170
Step-by-step explanation:
You have to multiply the amount of ounces you want converted by 28.35. Then you have your ounces converted to grams.
If you use this formula then you would have, 170 X 28.35 = 170.1
When you round 170.1 to the nearest whole number you will get 170.
The conversion of 6 ounces into grams is 170 grams.
What is unit conversion?Multiplication or division by a numerical factor, selection of the correct number.
Multiply the number of ounces you want to be converted by 28.35. Use the conversion.
1 ounces = 28 .35 grams
6 ounces = 6 x 28.35 grams
6 ounces = 170 grams.
Hence, 6 ounces is equal to 170 grams.

Solve the following literal equation for x.
ax-b/c=d
Answer:
x = (d + b/c)/a
or x = d/a + ba/c
Step-by-step explanation:
1. ax - b/c = d
2. ax = d + b/c
3. x = (d + b/c)/a (can also be written as x = (d + b/c)*1/a)
4. x = d/a + ba/c
Step 1 is given.
In step 2, b/c was added to both sides of the equation. This works because division is ahead of subtraction in the order of operations.
In step 3, both sides were divided by a.
(optional) In step 4, 1/a was multiplied by the values inside the parenthesis as a means to further simplify the equation.
Ann, Ben, and Cindy were eating strawberries. The ratio of the numbers of berries they ate is 5:5:7. If Cindy ate 30 strawberries less than Ann and Ben together, what is the total number of strawberries the three of them ate?
Answer:
Answer:
170
Step-by-step explanation:
Ann, Ben, and Cindy were eating strawberries.
The ratio of the numbers of berries they ate is 5:5:7.
If Cindy ate 30 strawberries less than Ann and Ben together,
find:
what is the total number of strawberries the three of them ate?
solution:
add the ratios 5 + 5 + 7 = 17
since Cindy ate 30, less than Ann and Ben together so, the equation is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
cindy 7 x 10 = 70
total = 170

Step-by-step explanation:
The denominators are 2, 3, and 4. The least common denominator is the least common multiple (LCM) of these numbers.
To find the LCM, first write the prime factorizations.
2 = 2¹
3 = 3¹
4 = 2²
The LCM is therefore 2² × 3 = 12.
Rewrite the fractions with a denominator of 12.
⁷/₄ + ¹/₂ + ⁵/₃ + ¹/₃ + ¹/₄ + ¹/₂
= ²¹/₁₂ + ⁶/₁₂ + ²⁰/₁₂ + ⁴/₁₂ + ³/₁₂ + ⁶/₁₂
Now that the denominators are the same, we can simply add the numerators.
= ⁽²¹⁺⁶⁺²⁰⁺⁴⁺³⁺⁶⁾/₁₂
= ⁶⁰/₁₂
= 5
30 POINTS AND WILL MARK BRAINLY Graph the line that passes through the points (-3,-8) and (2,-3) and determine the equation of the line
Answer:
y = x - 5 :)
Step-by-step explanation:
use point-slope form to create an equation for this line.
find the slope first by subtracting the y-values from each other, and the x-values from each other.
-3-(-8) = 5 <- y-value
2-(-3) = 5 <- x-value
5/5 = 1 <- slope
plug the slope and one of the points into the point-slope equation.
y - (-3) = 1(x - 2)
y + 3 = x - 2
subtract 3 from both sides.
y = x - 5
graph this by placing a point on -5 on the y-axis, and going up by 1 and right by 1 for the slope of 1.
hope this helped! xoxxo
Step-by-step explanation:
Hey there!
The line passes through points; (-3,-8) and (2,-3).
Now; use formula for double point.
[tex](y - y1) = \frac{y2 - y2}{x2 - x1} (x - x1)[/tex]
Put all values.
[tex](y + 8) = \frac{ - 3 + 8}{2 + 3} (x + 3)[/tex]
Simplify it.
[tex](y + 8) = \frac{5}{5} (x + 3)[/tex]
[tex]y = x + 3 - 8[/tex]
[tex]y = x - 5[/tex]
Therefore, the equation is y= x-5.

What is an equation of the line that passes through the point (6,6) and is parallel to the line 3x-2y=4?
Answer:
Fraction: y= 3/2x-3
or
Decimal: y= 1.5x-3
Step-by-step explanation:
Turn 3x-2y=4 into y=mx+b form
Subtract 3x from both sides
-2y=4-3x
Divide -2 from both sides
y= -2+3/2x
y= 3/2x-2
Since the line is parallel, use slope 3/2
Put point (6,6) into equation to find b

What conclusion can you draw from the following statements using the Law of Syllogism?
• If a figure is a square, then it has four sides.
• If a figure has four sides, then it is not a triangle
The potions for the answer is in the photo
Using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.
The law of Syllogism is a method of deductive reasoning which involves drawing a conclusion from two premises.
Applying this law, there are usually three statements.
The first and second statements are the premises. The first statement is the major premise that connects to the second statement.The third statement is the conclusion derived from the two premises stated earlier.For example:Statement 1: If a, then b (premise)
Statement 2: If b then c (premise)
Statement 3: If a, the c (conclusion)
In the question above, in the same vein, from the first and second statement, we can conclude that:
If a figure is a square, then it is not a triangle, because a square has 4 sides and a triangle doesn't.
Therefore, using the Law of Syllogism, the conclusion that you can draw from the two given premises is: C. If a figure is a square, then it is not a triangle.

The slope of MN
The slope of M'N'
Answer:
(in order): 4, 8, -2, -2
Step-by-step explanation:
The slope of MN = -1.
The slope of M.N. = -1.
What is a slope?The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
Given information:
The two lines MN and M'N' are parallel.
Transformation rule:
Line MN was translated down to 4 units and right to 6 units to create line M'N'.
And line MN passes through two points (-2, 0) and (-6, 8).
Therefore, the slope of line MN,
= (8- 0)/(-6-2)
= -1
Since lines MN and M'N' are parallel, they have the same slope.
Therefore, the slope of M'N' is also -1.

5 less than a number is equivalent to 1 more than three times the number. the number is
Answer:
x = -1
Step-by-step explanation:
5 less than a number is equivalent to 1 more than three times the number
number = x
x - 5 = 3x + 1
now im going to get the numbers and variable on different sides
x - 5 + 5 = x
3x + 1 - 3x = 1
x + 3x = 4x
1 - 5 = -4
4x = -4
lastly im going to divide each side by 4
4x / 4 = x
-4 / 4 = -1
x = -1

b. If Murphy is 60 years old, how old is Emma?
Answer:
X=60+6×2
Step-by-step explanation:
Sorry im not great at math but i think that this would be the answer because Murphy is 6 years younger than Emma. It then says TWICE so i assume it means multiply by two. 6×2= 12 so Emma is 12 years older.
