Answer:
I think is NaH x 10°-23A sales associate at a computer electronics store
is given a choice of two different salary plans.
One plan pays a weekly salary of $180 with a
commission of $30 for every computer sold. The
other plan pays no salary but offers $75
commission on each computer sold. How many
computers must the sales associate sale to make
the same amount of money under both plans?
Answer:
the sales associate has to sell 4 computers to make the same amount of money under both plans
Step-by-step explanation:
y=money
x=computers sold
Plan 1: y=30x+180
Plan 2: y=75x
75x=30x+180
45x=180
x=4
-6(-5x-1) = 5x+20
WHAT DOES X EQUAL??
Step-by-step explanation:
30x +6= 5x+20
30x -5x=20-6
25x=14
25x÷25=14÷25
x=0.56
r+ 4f when r=-6 and f=-5
Answer:
-26.
Step-by-step explanation:
Substitute the numbers and letters like this
-6 + (-5 x 4)
Which would evaluate to -6 + -20
And since it's the same sign, you can make it -6 - 20.
That equals -26.
Which statement is true about milliliters and liters?
There are 30 milliliters in 3 liters.
There are 300 milliliters in 3 liters.
There are 3,000 milliliters in 3 liters.
There are 3,000 liters in 3 milliliters.
Answer: Choice C) There are 3000 milliliters in 3 liters
mL is the abbreviation for milliliters
L is the abbreviation for liters
Since 1000 mL = 1 L, we can multiply both sides by 3 to get 3000 mL = 3 L
Simplify the expression 5(3x - 7 + 4y)
Answer:
15x - 35 + 20y
Step-by-step explanation:
Simplify. Distribute 5 to all terms within the parenthesis:
5(3x - 7 + 4y) =
5 * 3x = 15x
5 * -7 = -35
5 * 4y = 20y
15x - 35 + 20y is your answer.

A coat hanger is in the shape of isosceles triangle ABC shown in the figure. Sides AB and BC are congruent.
If angle BAC = 22 degrees the angle ABC = ?
Answer:
136 degrees
Step-by-step explanation:
if BAC is 22 degrees, than BCA is also 22 degrees. together that's 44 degrees. triangles are 180 degrees in total so 180 - 44 is 136
Answer:
Angle ABC is equal to 136 degrees.
Step-by-step explanation:
Since sides AB and BC are congruent (meaning they are equal to each other), they will have the same angle measurement. So, angle BAC and angle BCA will both have a measure of 22 degrees.
Triangles always add up to 180 degrees, so add 22 and 22 together, and subtract from 180. This leaves you with 136 degrees for angle ABC.
136 + 22 + 22 = 180, so this works!

Maria and jamal each have gardens. The area of Maria's garden is represented by the expression 8x^2 - 3x. Jamal's garden is a rectangular plot with the width and length represented by the expressions 3x and 4x-2. Which expressions give how much bigger or smaller Jamal's garden is compared to Jessica's? Check all that apply. 4x^2-9x -4x^2+3x 4x^2-3x 12x^2-6x-8x^2-3x 12x^2-6x-8x^2+3x
Answer:
4x^2 - 2x
Step-by-step explanation:
Area of Maria's garden = 8x^2 - 4x
Jamal's garden
Width = 3x
Length = 4x - 2
Area of Jamal's garden = length × width
= (4x - 2) (3x)
= 12x^2 - 6x
Difference in area of Jamal's garden and Maria's garden
Jamal's garden - Maria's garden
(12x^2 - 6x) - (8x^2 - 4x)
12x^2 - 6x - 8x^2 + 4x
4x^2 - 2x
The difference is the areas of their garden is 4x^2 - 2x

One gallon of gasoline in Buffalo, New York costs $2.29. In Toronto, Canada, one liter of gasoline costs $0.91. There are 3.8 liters in one gallon. How much does one gallon of gas cost in Toronto? Round your answer to the nearest cent. Is the cost of gas greater in Buffalo or in Toronto? How much greater?
Answer:
-To find the cost of one gallon of gas in Toronto, you have to multiply the cost of one liter of gasoline for 3.8 as you know that there are 3.8 liters in one gallon:
$0.91*3.8=$3.46
This means that a gallon of gas cost $3.46 in Toronto.
-$3.46-$2.29=$1.17
Considering that one gallon of gasoline cost $2.29 in Buffalo and $3.46 in Toronto, the cost is greater in Buffalo. The cost is greater by $1.17.
AB¯¯¯¯¯is a radius. CD←→is tangent to circle A at point B, where AB=7 and EC=18. What is BC?
Circle with center point A. Radius AB is drawn. Tangent line CD is drawn and intersects the circle at point B. Segment AC is drawn from the center point A through point E on the circle to point C on line CD. The lengths of segments are not provided.
BC =
Answer:
BC is 24 units
Step-by-step explanation:
Given that: AB = 7 units
EC = 18 units
From a sketch for the question, we have a triangle ABC. Such that:
AC = AE + EC
But,
AE = AB = 7 (radius of the circle)
So that,
AC = 7 + 18
= 25 units
Applying Pythagoras theorem to triangle ABC, we have:
[tex]/AC/^{2}[/tex] = [tex]/AB/^{2}[/tex] + [tex]/BC/^{2}[/tex]
[tex]25^{2}[/tex] = [tex]7^{2}[/tex] + [tex]/BC/^{2}[/tex]
[tex]/BC/^{2}[/tex] = 625 - 49
= 576
BC = [tex]\sqrt{576}[/tex]
= 24
Thus, BC is 24 units.

a) The temperature in the morning was - 12º.
How many degrees warmer is - 9°?
Answer:
-3
Step-by-step explanation:
The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. If Shawn knows that the slope of the line is 4 and the line passes through the point (1,8), which equation should be use to find the y-intercept and what is the y-intercept of the line?
Answer:
y = 4x + 4
Step-by-step explanation:
Plug in your x and y coordinates
8 = 4(1) + b
8 = 4 + b get your constants together by subtracting 4 from both sides
4 = b

what is x and y shown in the photo above?
Answer:
[tex]\huge\boxed{x = 11,\ y = 3}}[/tex]
Step-by-step explanation:
In order to find the value of x and y in this, we have to note a couple of angle relationships.
We know that angles [tex]13x-19[/tex] and [tex]9x+25[/tex] are the same because they are corresponding angles. This means that when a line intersects two parallel lines, the angles formed are congruent to the second line.
This means both expressions for the line will be equal to each other:
[tex]13x-19 = 9x+25[/tex]
We can now solve for x.
Add 19 to both sides:
[tex]13x = 9x+44[/tex]
Subtract 9x from both sides:
[tex]4x=44[/tex]
Divide both sides by 4:
[tex]x=11[/tex]
Now that we know that x = 11, we can use another angle relationship to find y.
We know that [tex]13x-19[/tex] and [tex]17y+5[/tex] are supplementary angles. This means their angle measurements add up to 180°.
Since we know the value of x, we can find the measure of the angle [tex]13x-19[/tex].
[tex]13(11) -19\\\\143-19\\\\124[/tex]
So the [tex]13x-19[/tex] angle is equal to 124 degrees. Since this and [tex]17y+5[/tex] are supplementary, that means [tex]17y+5[/tex] must be equal to [tex]180-124=56[/tex] degrees.
[tex]17y+5=56[/tex]
Subtract 5 from both sides:
[tex]17y=51[/tex]
Divide both sides by 17:
[tex]y=3[/tex]
So, x = 11 and y = 3.
Hope this helped!
Answer:
Y=3
X=11
Step-by-step explanation:
9x + 25 is = to 13x - 19 so you would do exactly that.
9x + 25 = 13x -19
-9x -9x
25 = 4x -19
+19 +19
44 = 4x
4 4
11 = x
9*11+25= 124
And 124 is not equal to 17y+5 so the equation would be
124 + 17y +5 = 180
124 + 5 = 130
129 + 17y = 180
-129 -129
17y = 51
17 17
Y= 3

A drivers distance varies directly as the amount of time traveled. After 6 hours, a driver had traveled 390 miles. How far had the driver traveled after 4 hours?
The distance traveled after 4 hours is 260 miles.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 = 9 is an equation.
We have,
Distance ∝ Time
Distance = K x Time
Now,
390 = 6K
K = 390/6
K = 65
Now,
Distance = 65 x 4
Distance = 260 miles
Thus,
After 4 hours the distance traveled is 260 miles.

Given; D is the Midpoint of CE / Prove DE =1/2CE
Answer:
Check explanation
Step-by-step explanation:
Here, we want to make a prove;
Mathematically , since D is the midpoint of CE
Then;
CE = CD + DE
Also, since D splits the line segment into two equal parts as the midpoint, then CD must be equal to DE
I.e CD = DE
Hence, we can express CE as follows;
CE = DE + DE
CE = 2 DE
Divide both sides by 2
CE/2 = DE
Hence; DE = 1/2 CE
