Answer:
x + 8
Step-by-step explanation:
1. To simplify this expression, we have to combine like terms.
(-4x + 2x + 3x) + (8)(-2x + 3x) + (8)x + 8Therefore, the answer is x + 8.
A bike rental costs $8 per hour. Desiree has a coupon for 2 free hours. To find how many hours she can rent with $40, Desiree sets up the equation 8(x – 2) = 40, where x is the number of hours.
Answer:
40
Step-by-step explanation:
8x = 56
8x + 16 = 40
x = 3
8x = 24
x = 7
8x – 16 = 40
8(x – 2) = 40

The broccoli farmer notices that his pre-flowering crop is being attacked by caterpillars. He was advised to use a particular insecticide at the rate of 5 milliliters per gallon of water. The farmer finds that a 4 gallon can of water covers an area of 30m². The chemical in question comes in 1500ml bottles and costs $3,500.
FIND:
a) How many gallons of water would cover his 2.6-hectare area?
b) How many pesticides is needed to adequately spray the field?
c) What would be his total cost for whole bottles of insecticide needed?
pls help
Answer:
a) 3,467 gallons of water
b) 17,335 ml of insecticide = 12 bottles
c) $ 42,000
Step-by-step explanation:
1 gal. Water = 3785.412 ml
1 hectare = 10,000 m^2
2.6 hectare = 2.5 x 10.000 m^2 = 26,000 m^2
(a) 4 gal. water cover 30m^2
X gal water cover 26,000 m^2
(4 x 26,000)/30 = 3,467 gal of water
(b) 5 ml per 1 gal of water
X ml per 3,467 gal of water
(5 x 3,467) = 17,335 ml of insecticide
Bottle of insecticide = 1,500 ml of insecticide in each bottle.
17,335/1,500 = 12 bottles of insecticide
(c) 12 x $3,500 = $ 42,000

are the linear expressions equivalent?
2x-3(1.3x-2.5)=5.9x+7.5
3-2(-2.6x+2.1)=5.2x-1.1
d
Answer:
not equivalent expressions
Step-by-step explanation:
Expand and simplify both expressions
2x - 3(1.3x - 2.5) - 5.9x + 7.5 ← distribute parenthesis
= 2x - 3.9x + 7.5 - 5.9x + 7.5 ← collect like terms
= - 7.8x + 15
----------------------------------------
3 - 2(- 2.6x + 2.1) - 5.2x - 1.1 ← distribute parenthesis
= 3 + 5.2x - 4.2 - 5.2x - 1.1 ← collect like terms
= - 2.3
Then the 2 expressions are not equivalent
Answer:
2x-3(1.3x-2.5)=5.9x+7.5
Equivalent Expression3-2(-2.6x+2.1)=5.2x-1.1
Not Equivalent ExpressionStep-by-step explanation:
Solving the first linear expression
2x-3(1.3x-2.5)=5.9x+7.52x-3.9x+7.5=5.9x+7.52x-3.9x-5.9x = 7.5-7.5-7.8x = 0x = 0/-7.8x = 0Thus, we can say that it's an equivalent expression.
Now Solving the second linear expression
3-2(-2.6x+2.1)=5.2x-1.13+5.2x-4.2= 5.2x-1.15.2x-5.2x = -1.1-3+4.20 ≠ 0.1Thus, we can say that it's not an equivalent expression.

if y=0.9 when x=2.4, find y when x=6.4
Answer:
2.4
Step-by-step explanation:
You have to divide 6.4 by 2.4 to get 2.66666666667.
Then you multiply 2.66666666667 and 0.9 to get 2.4
When x = 6.4, y = 2.4

the sum of the measures of the angles of all triangles is 180 degrees.if one angle of the triangle measures 45 degrees,and other two angles are equal.what is the measure of the other two angles?
Answer:
67.5 degrees.
Step-by-step explanation:
Let the measure of two equal angles of the triangles is x.
Thus, the angles of the triangles are x, x and 45 degrees.
Answer:
67.5°
Step-by-step explanation:
Given:
All triangles is 180°
One Triangle measure 45°
2 Other Angles are equal
To Find:
Two Other Angles
Solution:
180°- 45° = 135°
135° ÷ 2 = 67.5°
Therefore the other two angles are 67.5°

5. The length of a red rectangle is 12 cm more than its width, w. A blue
rectangle, which is 4 cm wider and 2 cm shorter than the red one, has
perimeter 72 cm. Make a sketch of the rectangles expressing all dimensions in
terms of w. Then find the dimensions of the red rectangle.
Answer:
For the red triangle the width is 9 cm and the length is 24 cm. For the blue triangle, the width is 14 cm and the length is 22 cm.
Step-by-step explanation:
Red triangle: width is 9 cm, length is 24 cm, blue one width is 14 cm and the length is 22 cm. hope this helps. did this quickly! <3
Answer:
Step 1. Perimeter P means adding up all 4 sides of a rectangle.
Step 2. Let w be the width of the red rectangle
Step 3. Let w+15 be the length of the red rectangle
Step 4. Let w+5 be the width of the blue rectangle
Step 5. Let w+15-2=w+13 be the length of the blue rectangle
Step 6. Then for the blue rectangle, P=w+5+w+5+w+13+w+13=4w+36=72
Step 7. Solving 4w+36=72
Subtract 36 from both sides of the equation
4w=36
Divide by 4 to both sides of the equation
ANSWER: For the red triangle the width is 9 cm and the length is 24 cm. For the blue triangle, the width is 14 cm and the length is 22 cm.
What algebraic rule did you use to preform this
translation????
Answer:
In geometry, a transformation is an operation that moves, flips, or changes a shape (called the preimage) to create a
new shape (called the image). A translation is a type of transformation that moves each point in a figure the same
distance in the same direction. Translations are often referred to as slides. You can describe a translation using words
like "moved up 3 and over 5 to the left" or with notation. There are two types of notation to know.
1. One notation looks like T(3, 5). This notation tells you to add 3 to the x values and add 5 to the y values.
2. The second notation is a mapping rule of the form (x, y) → (x−7, y+5). This notation tells you that the x and
y coordinates are translated to x−7 and y+5.

The location of the vertex Q after the dilation is (-2,-2). What is the location of vertex M after the dilation?
The location of vertex M after the dilation by a factor of 1/4 is at (-4, 3)
Dilation is a way of moving an object from a point on a plane to another location.
From the diagram attached, the coordinate of the vertex Q is at (-8, -8).
If the vertex Q after the dilation is (-2,-2), this means that the original coordinate is dilated by a factor of 1/4.
The vertex of coordinate M from the diagram is (-16, 12). Dilating the coordinate using a scale factor of 1/4 will give;
M' = (-16/4, 12/4) = (-4, 3)
Hence the location of vertex M after the dilation is at (-4, 3)

A line has a slope of -2/3 and passes through the point (-3, 8). what is the equation of the line ?
Answer:
y = -2/3x + 6
Step-by-step explanation:
replace the coordinates in the equation
y= mx + c
y= 8
x= -3
8= -2/3 (-3) + c
c + 2 = 8
c = 8 - 2
c = 6

What is the equation of the line passing through the points (1, 5) and (0, -3)
Answer:
The equation of this line is y=8x-3, I hope this helps you! :D
Answer:
y = 8x - 3
Step-by-step explanation:
The point (0, -3) is the y-intercept. You can take this and calculate the slope using the other point. Then you can form the formula y = mx+b.
Which of the following represents the equation of a line that is parallel to 2y-x=16 and passes through the
point (-6, 1)?
The equation of a line that is parallel to (2y - x = 16) and passes through the point (-6, 1) is [tex](y - 1)=0.5(x+6)[/tex] and this can be determined by using the slope-intercept form of the line.
Given :
Line Equation -- 2y - x = 16Point -- (-6,1)First, convert the given line in slope-intercept form that is in the form of (y = mx + c).
2y = x + 16
[tex]y = \dfrac{1}{2}x +16[/tex]
Comparing the above equation with slope-intercept form.
m = 0.5
c = 16
The line parallel to the line (y = 0.5x + 16) means the slope of that line is also equal to 0.5.
The equation of the line whose slope is m and passing through the point [tex](x_1,y_1)[/tex] is given by:
[tex](y-y_1) = m(x-x_1)[/tex]
Now, put the value of slope m and point [tex](x_1,y_1)[/tex] in the above equation.
[tex](y - 1)=0.5(x+6)[/tex]
So, the equation of a line that is parallel to (2y - x = 16) and passes through the point (-6, 1) is [tex](y - 1)=0.5(x+6)[/tex].
