Answer:
x = 4.125 or [tex]4\frac{1}{8}[/tex]
y = -0.875 or [tex]-\frac{7}{8}[/tex]
Step-by-step explanation:
5x + 3y = 18
3x - 3y = 15
3y and -3y can be cancled out becuase + and - cancel out and they both have 3y in them. We don't have to switch any signs in this case. You can just add them all exept 3y and -3y becuase they will be canceled out.
8x = 33
x = 4.125
Now we know what x is. We need to figure out what y is now. To figure out y chose an equation from the problem and plug in the x value. Lets chose 3x - 3y = 15.
3(4.125) - 3y = 15
12.375 - 3y = 15
-3y = 2.625
y = -0.875
Now we know what y is. I hope this helps :)
A farmer says that for every row of tomato seeds he plants, he can harvest 6.5 bushels of tomatoes. The farmer needs to harvest at least 52 bushels of tomatoes. What is the least number of rows of tomato seeds that the farmer will need to plant?
Answer:
8 rows
Step-by-step explanation:
The answer is 8 because 52 divided by 6.5 is 8
The least number of rows of tomato seeds that the farmer needs to plant is 8 row.
Given that, a farmer says that for every row of tomato seeds he plants, he can harvest 6.5 bushels of tomatoes.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
The farmer needs to harvest at least 52 bushels of tomatoes.
The number of rows of tomato seeds need to plant = 52/6.5
= 8
Therefore, the least number of rows of tomato seeds that the farmer needs to plant is 8 row.

i need help please
Answer:
1/2 or 2
Step-by-step explanation:
If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.
The scale factor of the dilation is 1/2.
What is scale factor?Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given:
Before dilation
AC= 8, BC= 10 abd AB= 6
After dilation
AC= 4, BC= 5 and AB= 3
Now, scale factor
Scale factor = Dimensions of the new shape / Dimensions of the original shape.
So,
scale factor = 4/8 or 5/10 or 3/6 = 1/2
Hence, the scale factor is 1/2.

A coach is ordering shirts for a team.
• The coach pays a one-time fee of $24.
• The coach also pays $8 for each shirt ordered.
Which function can be used to find c, the total amount the coach pays in dollars when k shirts are ordered?
Answer:
C=8k+24
Step-by-step explanation:
Answer:
24+8k=c
Step-by-step explanation:
Because he paid $24 but then he paid $8 per shirt but we don't know how many shirts he bought so that is where c comes in. K is the variable that gives us the full amount he paid for the one-time fee and the shirts all together.

Answer:
I'd say, the more thrust it has the longer its trajectory will be.
Step-by-step explanation:
Answer:
The relative magnitude and direction of the forces determines the flight trajectory of the rocket. At launch, the thrust of the rocket engine is greater than the weight of the rocket and the net force accelerates the rocket away from the pad. Unlike full scale rockets, model rockets rely on aerodynamics for stability. I hope that helps.

A block of clay contains twenty 4 - ounce portions of clay. Ceramics teacher wants to use the block to make as many spheres of clay as possible. Each weighing ⅖ pound. How Many spheres can the class make
Answer:
12.5
Step-by-step explanation:
20 x 4 = 80
80 ÷ 16 = 5
5 ÷ 2/5 = 12.5
Using 24 ounce portions of clay, maximum they can make 3 spheres.
Given that, a block of clay contains 24 ounce portions of clay.
What is metric conversion?Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
We know that, 1 pound = 16 ounces
So, 1 ounce = 1/16 pound
Then 24 ounce = 24/16
= 1.5 pound
Here, each sphere of clay weighing 2/5 = 0.4 pounds
Number of spheres = 1.5/0.4
= 3.75
Maximum 3 spheres
Therefore, using 24 ounce portions of clay, maximum they can make 3 spheres.

Step-by-step explanation:
so first, simplify the signs so they don’t confuse you,
-5/6 - 17/18 + 2/9 (Since there are two negatives near the end, and their tecxhnically being mulitplied, -2/9*-1 (I added 1 for place holder) and when you multiply a negatives by a negative, you get a positive.
So find the lcm of the denominators which is 18 in this case
-15/18 - 17/18 + 4/18
Now solve the problem from left to right
you’ll get -1 5/9 if you simplified

four times a number x is at least -12
an inequality is ?
the solution is ?
Answer:
-16
Step-by-step explanation:
im just taking a guess.
x+4>-12
-4 -4
---------------
4's cancel out and -12+-4=-16
Again this is just a guess.
The inequality is 4x ≥ -12 and the solution of this inequality is x ≥ -3.
What are Inequalities?Inequalities are the expressions having two sides connected with inequality symbols. Inequality symbols are <, >, ≤, ≥ and ≠. They may contain one or more variables and constants.
Inequalities which consist of one or more variables with the highest degree of the variables being 1 is called Linear inequalities.
Given that four times a number is at least -12.
Thus the inequality says that 4 multiplied with a number x, which is 4x has values -12 or greater than -12.
So the inequality is 4x ≥ -12.
Solving this,
4x ≥ -12
Dividing both sides by 4, we get,
4x/4 ≥ -12/4
x ≥ -3
Hence the inequality is 4x ≥ -12 and the solution is x ≥ -3.

Answer:
16 square units
Step-by-step explanation:
The formula for the area of a right triangle is ab/2 (a and b both being legs).
First, we find the legs' length which is MK and JK.
Since both points J and K are on the same y level, we look at the X coordinates and see how far apart they are.
Since both points M and K are on the same x level, we look at the Y coordinate.
M is 4 points away from K, so the leg MK is 4 units long.
J is 8 points away from K, so the leg JK is 8 units long.
Plug this into the formula and we get
[tex]\frac{4*8}{2}[/tex]
[tex]\frac{32}{2} = 16[/tex]
