Answer: a= 3b + 4c -8
Step-by-step explanation:
a= 3b + 4c -8
-2a + 6b = -8c + 16
-6b from the left the isolate a
-2a = -6b - 8c + 16
then divide by -2 to cancel it out
a = 3b + 4c -8
The equation is equivalent to -2a + 6b = -8c + 16 will be a= 3b + 4c -8
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
We are given the linear equation;
a= 3b + 4c -8
-2a + 6b = -8c + 16
-6b from the left the isolate a
-2a = -6b - 8c + 16
Then divide by -2 to cancel it out;
a = 3b + 4c -8

name one ray?
i’m not sure which is a ray .. lol
Answer: Ray BA and Ray BC
Explanation:
A ray starts at at a fixed point and moves forever in one direction. If we break line AC into two parts BA and BC, then we can form two opposite rays. Another ray points to the right but the letter marked for this isn't clear, so I'm not sure what to write for that ray. Same goes for the dashed ray that points to the left.
BD is a segment because both endpoints are fixed. We don't have either side extending forever in that direction.
a farmer grew 8,914 bushels of corn. he delivered corn to different stores using his truck. his truck can carry 336 bushels of corn in one load. what was the least number of loads the farmer made to deliver all the corn to the stores?
Answer:
The farmer had to do 27 loads.
Step-by-step explanation:
Basically the easy way to do this is to grab a calculator (or the paper and pen way) and keep adding 336 until you get to 8914.
Once you add it all you will see there is a remainder of his corn left (that has not been delivered):178
Even though it isn't a full 336, the farmer would still have to make another trip.
336*26=8,736
So, adding the remainder into it's own load, we would get:

What is a transversal angle?
When a transversal splits two parallel lines, the two intersections create a number of angles. Transversal angles are what those are.A transversal is a line that crosses a network of lines, according to the definition. Transversals include, for instance, a line that crosses a set of two parallel lines.A transversal line is one that crosses two other lines at two different locations. Line l meets a and b in the picture below at two different locations, P and Q. Line l is the transversal line as an outcome.1) ∠6 ≅ ∠8 congruent angle.

Henry and his children went into a restaurant that sells drinks for $2 each and tacos for $4 each. Henry has $40 to spend and must buy at least 14 drinks and tacos altogether. If x represents the number of drinks purchased and y represents the number of tacos purchased, write and solve a system of inequalities graphically and determine one possible solution.
One possible solution for the system of inequalities that models the situation is: (5,7), when he purchases 5 drinks and 7 tacos.
What is a system of inequalities?A system of inequalities is when multiple variables are related in a context, and then inequalities are built to find the numeric range of values that each variable can assume, according to the constraints in this problem.
For this problem, the variables are defined as follows, as stated in the text:
Variable x: number of drinks purchased.Variable y: number of tacos purchased.Both amounts cannot assume negative values, hence the first constraints are:
x ≥ 0.y ≥ 0.He must buy at least 14 drinks, hence:
x + y ≥ 14.
He must spend at most $40, hence, considering the price of each item, the constraint is given by:
2x + 4y ≤ 40.
The graphic solution to the inequality is given at the end of the answer. One possible solution is of (5,7), meaning that he buys 5 drinks and 7 tacos.

b^2=48, how do you answer a question like this? (also the words have nothing to do with the equation, i'm just confused)
The solution of the equation b² = 48 is b = 4√3
How to solve equation?The equation can be solved as follows;
b² = 48
Therefore, we are to find the value of b in the equation.
The value of b comes with a square sign, so we have to remove the square to make b stand alone in the equation.
By removing the square sign we have to square root both sides.
Hence,
b² = 48
square root both sides of the equation
b² = 48
√b² = √48
Therefore,
b = √16 × 3
b = 4√3

2) The value of x is; 2
3) The value of x is 10
4) The slope of the line is; 2
How to Interpret rule of transformation?
1) The rule of transformation for When the point M (h, k) is rotated through 90° clockwise about the origin, the point M (h, k) takes the image M' (k, -h). Thus, that is the rule here.
2) From the given image, we can tell that the angles 50° and 26x - 2 are corresponding angles. Thus, they are congruent and we have;
26x - 2 = 50
26x = 52
x = 2
3) From the given image, we can see that the given angles are supplementary and as such they add up to 180 degrees. Thus;
9x + 15 + 6x + 15 = 180
15x + 30 = 180
15x = 150
x = 10
4) Slope is;
