Martin likes to make flower bouquets that have 333 daffodils and 444 tulips per vase. A daffodil has a mass of ddd grams, a tulip has a mass of ttt grams, and the vase has a mass of vvv grams.
The expression 5(3d+4t+v)5(3d+4t+v)5, left parenthesis, 3, d, plus, 4, t, plus, v, right parenthesis describes the mass of 555 bouquets.
Match each amount in the situation with the expression that represents it.
Situation
Expression
Answer:
Answer:
Mass of a bouquet = v + 3d + 4t
Step-by-step explanation:
Mass of daffodil = d gm
Mass of Tulip = t gm
Mass of vase = v gm
Mass of a bouquet = mass of vase + Mass of 3 daffodils + Mass of 4 tulips
=> Mass of a bouquet = v + 3d + 4t
Flower bouquet weight = v + 3d + 4t
Answer:
Step-by-step explanation:
Situation Expression
Number of bouquets 555
Mass of one bouquet 3d+4t+v
Mass of the tulips in one bouquet 4t
Mass of the daffodils in one bouquet 3d
If EBCD is a parallelogram, EB = 16, ED = 25, BF = 11, EC = 34, mZBED = 55°, mZCDB = 67°,

Answer:
1. BC = 25
2. m∠EDC = 125°
3) BD = 22
4) m∠EBD = 67°
5) FC = 17
6) m∠BEC = 24°
7) CD = 16
8) m∠DBC = 58°
Step-by-step explanation:
The dimensions of parallelogram EBCD are;
EB = 16, ED = 25, BF = 11, EC = 34, m∠BED = 55°, m∠CDB = 67°
1. BC = ED = 25 Opposite sides of a parallelogram are equal
2. m∠BCD = m∠BED = 55 opposite angles of a parallelogram are equal
m∠BCD + mEDC = 180° adjacent sides of a parallelogram are supplementary
m∠EDC = 180° - m∠BCD
∴ m∠EDC = 180° - 55° = 125°
m∠EDC = 125°
3) BD = BF × 2 Diagonals of a parallelogram bisect each other
∴ BD = 11 × 2 = 22
BD = 22
4) m∠EBD = m∠CDB = 67° from alternate angles between parallel lines
5) FC = EC/2 from diagonals of a parallelogram bisect each other
∴ FC = EC/2 = 34/2 = 17
FC = 17
6) m∠BEC = m∠BCE = 24° Alternate angles between parallel lines
m∠BEC = 24°
7) CD = EB = 16 Opposite sides of a parallelogram are equal
8) m∠EBC = m∠EDC = 125° from opposite angles of a parallelogram are equal
m∠DBC + m∠EBD = m∠EBC from angle addition postulate
∴ m∠DBC = m∠EBC - m∠EBD
m∠DBC = 125° - 67° = 58°
m∠DBC = 58°
What is the slope of the line that passes through the points (5,−4) and (7, -4) ?Write your answer in simplest form.
Answer:
Undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
[tex] =\frac{ - 4 - ( - 4)}{7 - 5} \\ =\frac{ - 4 + 4}{2} \\ = \frac{0}{2} \\ (undefined)[/tex]
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.

Will give brainlist for correct answer.
Answer:
(-5, -1)
Step-by-step explanation:
When two lines intersect, their x and y values are equal. So,
x = 3y - 2 must equal -7 - 2y = x
x = 3y - 2 = -7 - 2y = x
Let's look at the two middle equations and solve for y.
3y - 2 = -7 - 2y
Add 2y to both sides
5y - 2 = -7
Add 2 to both sides.
5y = -5
y = -1
Now, let's find x. You can use either equation for this step.
When y = -1, then 3y - 2 =
(3)(-1) - 2 = -3 - 2 = -5
So, x = -5, and y = -1
Thus, the answer is (-5, -1)

Step-by-step explanation:
Consider the original parallelogram and the reduction.
What is the length of side A in the new parallelogram?
Given:
The given figure represents the original parallelogram and the reduction.
To find:
The length of side A in the new parallelogram.
Solution:
We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.
The corresponding sides of similar figures are proportional.
[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]
[tex]45\times A=5\times 18[/tex]
[tex]45A=90[/tex]
Divide both sides by 45.
[tex]A=\dfrac{90}{45}[/tex]
[tex]A=2[/tex]
The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.

−2x=x2−6 Rewrite the equation by completing the square.
Answer:
(x + 1)² = 7
Step-by-step explanation:
Given:
-2x = x² - 6
We'll start by rearranging it to solve for zero:
x² + 2x - 6 = 0
The first term is already a perfect square so that's fine. Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.
Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term. That value will of course be 1, giving us:
x² + 2x + 1 - 1 - 6 = 0
Now can group our perfect square on the left and our constants on the right:
x² + 2x + 1 - 7= 0
x² + 2x + 1 = 7
(x + 1)² = 7
To check our answer, we can solve for x:
x + 1 = ± √7
x = -1 ± √7
x ≈ 1.65, -3.65
Let's try one of those in the original equation:
-2x = x² - 6
-2(1.65) = 1.65² - 6
- 3.3 = 2.72 - 6
-3.3 = -3.28
Good. Given our rounding that difference of 2/100 is acceptable, so the answer is correct.

Answer:
(0, 19)
Step-by-step explanation:
Find the equation.
Find the slope:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
22-16/1-(-1) = 6/2 = 3
Here's our equation so far:
y = 3x + b
Find b by plugging in one pair of (x,y) coordinates.
22 = 3(1) + b
22 = 3 + b
b = 19
Now we now the equation:
y = 3x + 19
So, the y-intercept is 19.
15x-7y=-49 standard form to slope-intercept form
Answer:
y= \frac{15}{7}x + 7

B. Noah writes the equation 3 (x+7)=57 to represent the situation. DO YOU agree with him? Explain your answer.
Answer:
Yes , i agree with Noah that the equation would be 3(x + 7) = 57
Step-by-step explanation:
P.S - The exact question is -
To find - Noah writes the equation 3 (x+7)=57 to represent the situation.
DO YOU agree with him? Explain your answer.
Proof -
Yes , i agree with Noah
Because in the figure we can see that there is x written 3 times and 7 written 3 time and whole the values is equal to 57 .
Because 57 is divided into x 7 x 7 x 7
∴ we can write it as
3 times x + 3 times 7 = 57
⇒3(x) + 3(7) = 57
⇒3(x+7) = 57
Ans Noah give the same equation 3 (x+7)=57
So, I agree with Noah.

PLS HELP WITH BOTH SCREEN SHOTS I WILL MARK BRAINLIEST
Answer:
Answer 1. 3in
Answer 2. 0.875in
Answer 3. 26 miles
Answer 4. 7.67in
Step-by-step explanation:
Answer 1. We know that 2 feet in real life is going to equal 1 inch, so since the person is 6 feet, we divide that by 2 to get 3. So the action figure is going to be 3in.
Answer 2. In this case, we see that 1 foot is equal to four inches. That must mean that 1 inch is equal to a quarter foot. So we just multiply
0.25 x 3.5 = 0.875
The length is 0.875 feet
Answer 3.
We know that 1 inch = 6.5 miles, and there are 4 inches on the map, so we have to multiply 6.5 x 4 to find out how many miles there is.
Answer 4.
To find this one out, we have to divide 9 into 69. That gives us 7.67. So 69 nautical miles would be equal to 7.67 inches on the map
