-7 - 3x = 1x + 4(2 + x)
Step 2: Solve for x
Distribute 4: -7 - 3x = x + 8 + 4xCombine like terms: -7 - 3x = 5x + 8[Addition Property of Equality] Add 3x on both sides: -7 = 8x + 8[Subtraction Property of Equality] Subtract 8 on both sides: -15 = 8x[Division Property of Equality] Divide 8 on both sides: -15/8 = xRewrite/Rearrange: x = -15/8What is pi/4 a reference angle for
if you buy three stickers you get a 75% discount on third sticker if one sticker cost $.40 how much will three stickers cost you
Answer:
$1.10
Step-by-step explanation:
The first two stickers cost $0.8. The thrird one will cost 75% of the cost of one sticker. To find the answer, you multiply 0.75 (0.75 is 75% as a decimal) by 0.4 to get 0.3. $0.3 plus $0.8 equals $1.10.

Step-by-step explanation:
Write the slope-intercept form of the equation of the line through the given points.
through: (5,1) and (1, -3)
Answer:
y = x-4
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -3 -1)/( 1 - 5)
= -4/-4
= 1
Then using slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = 1x+b
Substitute one of the points in
1 = 5 +b
1-5 = b
-4 =b
y = x-4

Solve by elimination by filling in the blanks below.
We will cancel our x's in this problem!
-5x+4y=30
2x+3y=-12
Answer: (x, y)=(0, -6）
Step-by-step explanation:
To solve a system of equations there are usually 3 general ways.
- Elimination
- Substitution
- Augmented Matrix
Since the question is asked to use elimination, we are going to use it.
--------------------------------------------------------------------------------------
-5x+4y=30
2x+3y=-12
-10x+8y=60
10x+15y=-60
23y=0
y=0
------------------------------------------------------------------------------------------
Substitute the y value into any one of the equations
2x+3y=-12
2x+3(0)=-12
2x+0=-12
x=-6
Hope this helps!! :)

Ratnam hired a car from a car renting agency which charges a flat amount of Rs x for travelling up to 40 kilometres and Rs. y per km for every kilometre travelled thereafter. How much should Ratnam pay the agency for a journey of 50 kilometres in Rs. ?
Answer:
Rs. X + Rs. 10y
Step-by-step explanation:
Charge for 40 km travel = Rs. x per km
Charge for every additional km traveled = Rs. y
Amount paid for 50 km
Fixed charge for 40km = Rs. X
Additional km = 50 - 40 = 10 kilometer
Total charge :
Rs. X + Rs. 10y
Mr. Jalon owns a book store. He bought 100 books this week. 7 of them were ripped. What percent of this eggs were not ripped?
Answer:

Which ordered pair is a solution of the equation 5x+y=-23?
O (-3,-4)
O (-5,-3)
O (-4,-3)
O (-3,-5)
Answer:
5x-4+-20+ -3=-23
Step-by-step explanation:
5x-3= -15 + -4 = 11
5x-5=-25+-3=22
5x-4=-20+-3=-23
5x-3= -15+ -5= -20
Find the values of x and y
Answer:
x = 2
y = 12
Step-by-step explanation:
In triangle ABD, CE is the mid segment.
Therefore, by mid segment theorem:
2(5x - 3) = x + 12
10x - 6 = x + 12
10x - x = 12 + 6
9x = 18
x = 18/9
x = 2
Since, DE = EA
2y - 4 = y + 8
2y - y = 8 + 4
y = 12

Answer:
100
Step-by-step explanation:
Isosceles triangle have 2 equal angles. Therefore the second angle in the triangle will also be 25.
Since the sum of angles in a triangle is 180.
180-(25x2) will give you the last angle in one of the triangles.
The other angle is identical so the angle at the top of the other triangle will also be 130.
The sum of angles in a circle is 360.
Therefore, angle x = 360-(130x2)
X= 100
Can you solve number 1 please.
3x+16=7x
answer please
Answer:
x = 4
Step-by-step explanation:
We have the algebraic expression 3x + 16 = 7x and are asked to solve.
When we need to solve for x, we need to get x alone always.
So 3x + 16 = 7x.
Subtract 3x from both sides :
16 = 4x
Divide 4 from both sides :
x = 4
Answer:
[tex] \large \boxed{x = 4}[/tex]
Step-by-step explanation:
Goal
Solve for x-term.Given
Equation[tex]3x + 16 = 7x[/tex]
Step 1
Combine like terms. We move 3x to subtract 7x since we can't add with a constant with a variable.[tex]16 = 7x - 3x \\ 16 = 4x[/tex]
Step 2
Move 4 to divide 16 because we need to make x-term as the subject of equation.[tex] \frac{16}{4} = x \\ 4 = x[/tex]
Step 3
If you are not sure that the answer is correct, we can check the answer by substituting x = 4 in the equation.[tex]3x + 16 = 7x \longrightarrow 3(4) + 16 = 7(4) \\ 12 + 16 = 28 \\ 28 = 28[/tex]
The equation is true for x = 4. Hence, the solution is x = 4

Step-by-step explanation:
The combined height of one fir tree and one pine tree is 212121 meters. The height of 444 fir trees stacked on top of each other is 242424 meters taller than one pine tree. How tall are the types of trees that Logan genetically engineered?
Answer: The height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Step-by-step explanation:
Let x= height of each fir tree, y = height of each pine tree.
As per given, we have
x+y = 21 (i)
4x=y+24 (ii)
From (ii),
[tex]4x-y=24[/tex] (iii)
Add (i) and (iii), we get
[tex]5x=45\\\\\Rightarrow\ x=\dfrac{45}{5}\\\\\Rightarrow\ x=9[/tex]
Put value of x in (i), we get
[tex]9+y=21\Rightarrow y=12[/tex]
Hence, the height of each fir tree is 9 meters, and the height of each pine tree is 12 meters.
Answer:
Each fir tree is 9 meters tall and each pine tree is 12 meters tall.
