Answer:
15/14
Step-by-step explanation:
I am assuming you meant. 3(x+1/2)
10x-6=3x+3/2
7x=3/2+12/2
7x=15/2
x=15/2*1/7
x=15/14
The value of x from the given equation is 15/14.
The given equation is 10x-6=3(x+1/2)
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The given equation can be solved as follows
10x-6=3x+3/2
⇒ 10x-3x=3/2 +6
⇒ 7x = (3+12)/2
⇒ 7x = 15/2
⇒ x=15/14
Hence, the value of x from the given equation is 15/14.

Quadrants in the Coordinate Plane
The coordinate plane is divided into 4 quadrants named I, II, III, and IV as shown in the image attached below.
The first quadrant (I) has the x positive and the y positive
The second quadrant (II) has the x negative and the y positive
The third quadrant (III) has the x negative and the y negative
The fourth quadrant (IV) has the x positive and the y negative.
A point located in quadrant III must have both coordinates negative. This only corresponds to choice B where both components are negative.

Steve went to the concession stand and bought hamburgers and hot dogs for the kids he brought to watch a baseball game. Each child chose either one hamburger or one hotdog. Hot dogs cost $1.50 each and hamburgers cost $2.75 each. Steve spent a total of $23.75 on 10 kids.
(a) Could Steve have bought an equal amount of hamburgers and hot dogs? Justify your answer.
(b) If x represents the number of hotdogs purchased and y represents the number of hamburgers purchased, write a system of equations that models this situation and determine the number of both items bought.
Answer:
b)
x = 3 hotdogs
y = 7 hamburgers
Step-by-step explanation:
Steve went to the concession stand and bought hamburgers and hot dogs for the kids he brought to watch a baseball game. Each child chose either one hamburger or one hotdog. Hot dogs cost $1.50 each and hamburgers cost $2.75 each. Steve spent a total of $23.75 on 10 kids.
(a) Could Steve have bought an equal amount of hamburgers and hot dogs? Justify your answer.
An
(b) If x represents the number of hotdogs purchased and y represents the number of hamburgers purchased, write a system of equations that models this situation and determine the number of both items bought.
Let:
x = the number of hotdogs purchased y = the number of hamburgers purchased
Since the number of kids = 10
Our system for Equation is given as:
x + y = 10...... Equation 1
x = 10 - y
x × $1.50 + y × $2.75 = $23.75
1.5x + 2.75y = 23.75
Let us substitute 10 - y for x in Equation 2
1.5(10 - y) + 2.75 = 23.75
15 - 1.5y + 2.75y = 23.75
- 1.5y + 2.75y = 23.75 - 15
1.25y = 8.75
y = 8.75/1.25
y = 7 hamburgers
Solving for x
x = 10 - y
x = 10 - 7
x = 3 hotdogs
Therefore,
x = 3 hotdogs
y = 7 hamburgers

Answer:
61°
Step-by-step explanation:
We have many angles and are asked to find angle number 4.
Looking at the picture, if we take a look at the angle across (mirrored) from 4, we see that it lists being 61 degrees, since that angle is a complete mirror of angle 4. Angle number 4 is 61°
Answer:
the answer is 59
Step-by-step explanation:
a circle is 360 degrees, which means half of a circle is 180. This means the angles that are along ray q must add up to 180. if you add the 2 known angles
60+61
you can subtract that from 180
180 - (60+61)= measure angle 4
180 - 121 = measure angle 4
180 - 121 = 59

3 times a day Dylan mixes 2 oz of protein powder into a shake how many days can he make all 3 shakes from his 5 oz container of protein powder you #16 oz in a #
Answer:
13 days
Step-by-step explanation:
Protein powder in container = 16 oz
Number of containers = 5
Total ounces of protein powder = (16 * 5) = 80 oz
Oz of protein used per shake = 2 oz
Number of times shake is made per day = 3
Total oz used per day = 2 oz * 3 = 6 oz
Number of days hencan make all three shakes from container :
Total ounces / ounces per day
80 oz / 6 oz
= 13. 33 days

Kira earned $7 mowing her neighbor's lawn for of an hour. What is her hourly rate?
The hourly rate for Kira by mowing her neighbor's lawn is $7/hour.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
Kira earned $7 mowing her neighbor's lawn for an hour.
So,
$7 ⇒ 1 hour
So $7/hour will be the hourly rate.
Hence "The hourly rate for Kira by mowing her neighbor's lawn is $7/hour".

Answer:
see below
Step-by-step explanation:
6y = 12x + 26
15y = 45x + 60
First let's simplify these equations.
6y = 12x + 26
Divide each term by 6.
y = 2x + 26/6
Simplify the fraction.
26/6
= 13/3
Your simplified equation is:
y = 2x + 13/3
Let's simplify the other equation.
15y = 45x + 60
Divide each term by 15.
y = 3x + 4
These are your simplified equations.
y = 2x + 13/3
y = 3x + 4
We can see that the slope of the first equation is not equal to the slope of the second equation.
equation 1: slope is 2 shown from 2xequation 2: slope is 3 shown from 3xThe y-intercept of the first equation is not equal to the y-intercept of the second equation.
equation 1: y-intercept is 13/3 shown by + 13/3equation 2: y -intercept is 4 shown by + 4Now we want to solve the equations.
Both equations are equal to y, so you can set them equal to each other.
2x + 13/3 = 3x + 4
Combine like terms.
1/3 = x
Plug x = 1/3 into both of the equations separately..
y = 2(1/3) + 13/3
y = 2/3 + 13/3
y = 15/3
y = 5
y = 3(1/3) + 4
y = 3/3 + 4
y = 1 + 4
y = 5
Your solution is (1/3, 5)
The system of equations has one solution.

So, we see side AB, and side BC.
(Don't look at AB as a straight line like this, imagine it slanted if you want to)
If the slope is -3, and the intersection of AB and BC make a perpendicular, then a slope of [tex]\frac{1}{3}[/tex] would cause the right angle to form.
So, [tex]\frac{1}{3}[/tex] is the slope of BC.
