5.(x+3) = 2x-3 Help pls
Answer:
x= -6
Step-by-step explanation:
5.(x+3) = 2x-3
5x+15=2x-3
5x-2x+15=-3
5x-2x=-3-15
3x=-3-15
3x=-18
x=-6
Step-by-step explanation:
5(X+3) =2X_3
Expand the brackets
5X + 15 = 2X _ 3
CLT(Collect like terms)
5X_2X= _3 _ 15
3X = _ 18
DBS( Divide both sides) by 3
3X/ 3 = _18 / 3
X = _9

Answer:
(1,-4)
Step-by-step explanation:
First manipulate the second equation so that y is by itself
x-y=5
-y=-x+5
y=x-5
then substitute that y in for the y in the above equation and solve for y
y=-2x-2
x-5=-2x-2
3x-5=-2
3x=3
x=1
Now that you have the x-coordinate, find the y-coordinate by plugging in the x-value in either of the equations
y=-2x-2
y=-2(1)-2
y=-2-2
y=-4
I see that you're using deltamath, and I think for the graph questions, you could first place a point for the y-intercept of one of the equations, and then place another point that is on the graph of the equation. Once you plotted both lines, just see the point where they meet and that is where the two systems of equations meet.
Ricky ate 2 soft tacos, and 4 of his friends ate s soft tacos. If there were 18 2 points
soft tacos in all, how many soft tacos did his friends eat if each friend ate
the same amount? Ricky wrote the following equation to find the number
of soft tacos each friendate, 6s = 18. He then found out, from dividing that
each friend ate 3 tacos each. Do you agree/disagree with Ricky's thinking?
Explain.
Your answer
Your
Use the following table to answer questions #3, #4, and #5.
Answer:
Each friend ate 4 tacos.
Step-by-step explanation:
"4 of his friends ate s tacos" is unclear. I assume it should be
"4 of his friends ate s tacos each."
total tacos = 2 + 4s = 18
4s = 16
s = 4
His four friends ate a total of 16 tacos, each friend eating 4 tacos.
Ricky's reason, i.e., that 6s = 18, is incorrect.
6s = 4s+2s, where 4s is what his friends ate in total.
That implies that Ricky ate 2s tacos, instead of 2 tacos. If 2s = 2 then s = 1, but then 6s ≠ 18.

Find the perimeter of the triangle with vertices D(5, 6), E (10, 9), and F(7, 11). Do not
round before calculating the perimeter. After calculating the perimeter, round your
answer to the nearest tenth.
The perimeter is
units.
Answer:
Perimeter of triangle = 14.82 approx.
Step-by-step explanation:
Given:
D(5, 6)
E (10, 9)
F(7, 11)
Find:
Perimeter of triangle
Computation:
Distance = √(x1-x2)² + (y1-y2)²
Perimeter of triangle = DE + EF + FD
Perimeter of triangle = √(5-10)² + (6-9)² + √(10-7)² + (9-11)² + √(7-5)² + (11-6)²
Perimeter of triangle = √25 + 9 + √9 + 4 + √4 + 25
Perimeter of triangle = √34 + √13 + √29
Perimeter of triangle = 5.83 + 3.6 + 5.3851
Perimeter of triangle = 14.8151
Perimeter of triangle = 14.82 approx.

Answer / Step-by-step explanation:
4 * (2 + 3) - 12
To get our final answer, we need to follow PEMDAS, which is :
Parenthesis
Exponent
Multiply
Divide
Addition
Subtraction
These mean that this is the order you will solve by what is in the question, let us start with the parenthesis.
(2 + 3) fits this description, therefore we add them together :
4 * 5 - 12
There are no more parenthesis and also no more exponents, so move onto multiplying.
4 * 5 - 12
20 - 12
Now subtract :

Temperature Change In the United States, temperature is measured on the Fahrenheit temperature scale. On this scale, water boils at 212 degrees and freezes at 32 degrees. To denote a temperature of 32 degrees on the Fahrenheit scale, we write:
32 degrees F, which is read "32 degrees Fahrenheit"

A line goes through the point (-8,9), and has a slope of 3/4
Write in form of a Ax + B and C for this line
Answer:
[tex]y=\dfrac{3}{4}x+15[/tex]
Step-by-step explanation:
Given that,
A line goes through the point (-8,9), and has a slope of 3/4.
We need to express in the form of Ax+B for this line.
We have, m = 3/4
So,
[tex]y=\dfrac{3}{4}x+B[/tex]
Put y = 9 and x = -8 in the above equation.
[tex]9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15[/tex]
So,
[tex]y=\dfrac{3}{4}x+15[/tex]
It is the required equation of the line.

which of the following statements must be true if GHI-JKL ?
1. The corresponding sides of the two triangles must be proportional.
2.The two triangles must have exactly one acute angle.
3.At least one of the sides of the two triangles must be parallel.
4.The sides of the triangles must have equal lengths.
5. The two triangles must be scalene.
6. None of the above.
Answer:
1. The corresponding sides of the two triangles must be proportional.
Step-by-step explanation:
Option 1, is the only statement that makes GHI = JKL true. If the triangles are congruent, it means that the sides have to be proportional.
The triangles GHI and JKL are similar, Δ GHI ≈ Δ JKL only if their two corresponding sides are proportional and one angle is also equal, so option 1 is correct.
What is the triangle?Three straight lines coming together create a triangle. There are three sides and three corners on every triangle (angles). A triangle's vertex is the intersection of two of its sides. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.
Given:
The triangles GHI and JKL are similar, Δ GHI ≈ Δ JKL,
The condition for the similarity of the triangle are shown below,
Two triangles are said to be comparable if the ratio of one triangle's two sides to the two sides of another triangle is the same, and the angles that the two sides of both triangles inscribe are equal.
Thus, the sides have to be proportional.

As, we know that
tan(C) = [tex]\frac{Perpendicular}{Base} = \frac{86}{44} = 1.9545[/tex]

5.2 in.
9 in.
34.7 in.
81 in.

Step-by-step explanation:
V = 108π in³
h = 4 in
r = √(3V/(πh)) = 9 in
Answer:
B
Step-by-step explanation:
If you have 108 pi and then you divided it to find the radius and all that stuffy stuff you will end up getting 9 and if you dont want to do it that way just substitute each one of the answer chooses as the radius until the volume gets you 108 pi cubic inches.
How do you solve 2.5x + 10 = 50?
Answer:
I think the answered is x = 16 hope I right
Answer:
X = 16
Step-by-step explanation:
2.5x+10 = 50
distribute the ten to the other side by substracting
2.5x = 50-10
2.5x = 40
Now divide 2.5 on both sides
2.5x/2.5 = 40/2.5
x = 16
