40) How old am I if 400 reduced by 3 times
my age is 214?
Answer:
You are 62 years old
Step-by-step explanation:
Let's set up an equation:
400 - 3a = 214 ( let a be your age)
Add 3a to each side:
400 = 214 + 3a
Subtract 214 from each side:
186 = 3a
Divide each side by 3:
62 = a

Answer:
114 and 30Step-by-step explanation:
The angles with measure of 66 and x are consecutive interior angles and therefore supplementary:
x + 66 = 180x = 180 - 66x = 114The angles x and 4y - 6 are alternate interior angles and therefore congruent:
x = 4y - 6114 = 4y - 64y = 114 + 64y = 120y = 120/4y = 30Trigonometric identities: Performance task

Answer:
6x +5y = 45x +y = 8x = 5 . . . jars of jamy = 3 . . . packages of bread mixStep-by-step explanation:
The problem statement gives two relations between x (jars of jam) and y (packages of bread mix).
6x +5y = 45 . . . . . . total cost
x + y = 8 . . . . . . . . . number of items
__
These equations can be solved a number of ways. Substituting for y, we get ...
y = 8 -x
6x +5(8 -x) = 45
x +40 = 45
x = 5 . . . . . . . . . jam
y = 8 -5 = 3 . . . mix
There are 5 jars of jam and 3 packages of bread mix in the gift basket.

Carlos is going on a boat tour the boat will travel a total distance of 35 km during the seven hour tour if the boat travels at a consistent speed during the torr what distance in kilometers should the boat travel in three hours
Answer:
We can easily figure out how fast the boat is moving per hour.
35 km / 7 hours = 5 km/h
We now know that we are moving at a rate of 5 kilometers every 1 hour. We can now take our 5 km/h and multiply it by 3 hours to get our answer
5 km/h x 3 = 15 kilometers

find the equation of the linethe line passes through the points (5,2) and (-4,-4)
Answer:
[tex]y = \frac{2}{3}x - \frac{4}{3} [/tex]
Step-by-step explanation:
first find the slope using the above points then use the slope formula to calculate the slope
[tex]m = \frac{y2 - y1}{x2 - x1} \\ \frac{2 - - 4}{5 - - 4} = \frac{2 + 4}{5 + 4} = \frac{6}{9} = \frac{2}{3} [/tex]
substitute ⅔ for m and one of the above points into the y-intercept form of the equation for a line and solve for b
[tex]y = mx + b \\ 2 = \frac{2}{3} (5) + b \\ 2 = \frac{10}{3} + b \\ 2 - \frac{10}{3} = b \\ \frac{6}{3} - \frac{10}{3} = b \\ b = - \frac{4}{3} [/tex]
substitute the slope and the value for b into the equation to get the answer
[tex]y = \frac{2}{3} x - \frac{4}{3} [/tex]

-4 ( x + 2 ) = - 4x -5
Answer:
no solution
Step-by-step explanation:
- 4(x + 2) = - 4x - 5 ← distribute parenthesis on left side by - 4
- 4x - 8 = - 4x - 5 ( add 8 to both sides )
- 4x = - 4x + 3 ( add 4x to both sides )
0 = 3 ← False statement
This indicates the equation has no solution
Kaj bought snacks for her team's practice. She bought a bag of chips for $2.44 and a
20-pack of juice bottles. The total cost before tax was $26.44. Write and solve an
equation which can be used to determine j, how much each bottle of juice costs.
Answer:
j = $1.20
Step-by-step explanation:
26.44 (total cost) - 2.44 (cost of chips) = 24
$24 dollars (cost of pack of juice bottles) divided by 20 (number of juice bottles in the pack = 1.2
The required equation for the cost of 20 juice bottles is x = (26.44 - 2.44) / 20 and costs $1.2.
She bought a bag of chips for $2.44 and a 20-pack of juice bottles.
The total cost before tax was $26.44.
To determine and solve an equation that can be used to determine j, how much each bottle of juice costs.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the cost of the bottle be x,
According to the question,
2.44 + 20x = 26.44
20x = 26.44 - 2.44
x = [24] / 20
x = $1.2
Thus, the required equation for the cost of 20 juice bottles is x = (26.44 - 2.44) / 20 and costs $1.2.

2. Find the value of "a" given the vertex and a second point when the vertex is (3,-1) and the graph passes through (5, 2)
Answer:
a = 3/4
Step-by-step explanation:
Given the vertex, (3, -1) and the other point, (5, 2):
We could substitute these values into the vertex form of the quadratic equation:
y = a(x - h)² + k
Where:
(h, k ) = vertex
a = determines whether the graph opens up or down, and makes the graph wider or narrower.
If a is positive, the graph opens up; if a is negative, the graph opens down.If a is between 0 and 1, the graph is wider than the parent function.If a > 1, the graph is narrower than the parent function.h = determines how far left or right the parent function is translated.
k = determines how far up or down the parent function is translated.
Substitute the vertex, (3, -1) and point (5, 2) into the vertex form to solve for "a":
y = a(x - h)² + k
2 = a(5 - 3)² - 1
2 = a(2)² - 1
2 = a(4) - 1
Add 1 to both sides:
2 + 1 = a(4) - 1 + 1
3 = 4a
Divide both sides by 4 to solve for a:
3/4 = 4a/4
3/4 = a
Therefore, the value of a = 3/4. Since the value of a is positive, and that it is between 0 and 1, then it means that the graph opens upward and is wider than the parent function.
The quadratic equation in vertex form is: y = 3/4(x - 3)² - 1, where a = 3/4.
