-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

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

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 = 30The tens digit of a certain number is 2 less than the units digit. The sum of the squares of the two digits is 34. Find the number.

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]
Evaluate the expression. 4−[(11+12(−2)÷6)+1] What is the value of the expression? Enter your answer in the box.
Answer:
-4
Step-by-step explanation:
the number are measurements of radius , diameter, ans circumference of circles A and B. Circle A is smaller than Circle B.
Which number belongs to which quantity? 2.5, 5, 7.6, 15.2, 15.7, 47.7
Step-by-step explanation:
a diameter is always twice the radius.
the only pairs I can see in the list, where one number is twice the other :
2.5 and 5
7.6 and 15.2
so,
2.5 is the radius of A
5 is the diameter of A
7.6 is the radius of B
15.2 is the diameter of B
15.7 is then the circumference of A (as the smaller of the remaining 2 numbers)
47.7 is the circumference of B
we can also check via the formula for circle circumference :
c = 2×pi×r
and yes, the rounded c for r=2.5 is 15.7, and for r=7.6 is 47.7

A square cake measures 6 units by 6 units by 4 units. The cake falls into a vat of frosting and comes out frosted on all six faces. The cake is then cut up into cubes, each measuring 1 unit on an edge How many of these cubes will have exactly one face frosted?
Answer:
Out of 36 cubes on each face, the 16 cubes not on an edge are the only ones frosted on a single face. 16 on each face x 6 faces = 96 cubes frosted on one face.
Step-by-step explanation:
Hope it helps!
There are 64 cubes that are frosted on one side only.
What is a cube?"A Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges. It is also said to be a regular hexahedron."
What are 3D shapes?"Shapes in three-dimensions or as we view them in real life are called 3D shapes. Examples of 3D shapes are cubes, cuboids, spheres, cylinders, cones and frustum of cones."
Each face will have three types of cubes on it:
1. Corner Cubes - Frosted on three adjacent sides
2. Edge Cubes - Frosted on two adjacent sides and on the edge between two corner cubes.
3. Central Cubes - Frosted on one side and in the middle of all edges of the face.
Thus, the number of cubes that have only one side as frosted are the total number of central cubes. They can be calculated as follows for all 6 faces:
[tex]Cubes_{central}[/tex] = (6−2)(6−2)+(6−2)(4-2)+(6−2)(4−2)+(6−2)(6−2)+(6−2)(4−2)+(6−2)(4−2)
= [tex]2 (4)^{2}+4(4)(2)[/tex]
= 32+ 32
= 64
Thus there are 64 cubes that are frosted on one side only.

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.

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.
