explanation :
8x + 7y + 4 - 6x + 15y + 16
then, equate denominator
8x - 6x +7y + 15y + 4 + 16
the answer is
2x + 22y + 20
hope this will help you
Answer:
2x + -8y + -20
Step-by-step explanation:
First solve the parenthisis.
(8x + 7y + 4) - 3(2x - 5y -8)
8x + 7y + 4 - 6x - 15y - 24
Now the like terms... combine 8x and -6, 7y and -15y, last but not least -24 and 4.
To end up with 2x -8y -20
a)In the scale drawing, the height of the houses is 8 inches. What is the height of the real house?
b)The length of the real house is 35 feet. What is the length of the house in the scale drawing.
Answer:
a) 40 ft
b) 7 inches
Step-by-step explanation:
A) Multiply the given scale factor by 8 to get 8 inches:
1 in : 5 ft ⇒ 8 in : 40 ft
The real house is 40 ft high.
__
B) If you like, you can write the proportion ...
dwg / (35 ft) = 1 in / (5 ft)
Multiplying by 35 ft gives ...
dwg = (1 in)×(35 ft)/(5 ft) = 7 in
The length of the house in the scale drawing is 7 inches.
Answer:a=40
b=7

A shirt is on sale for 40% off. The sale price is $12. How much was the original price? *
Answer:
$20
Step-by-step explanation:
Let the variable x in this equation represents the original price of the shirt:
100% - 40% = 60%
60% of x = $12
0.6x = $12
x = $12/0.6
x = $20

Answer:
You could solve this by taking the y value and adding it to the multiplied rate.
For example: For Jill's 6 year mark, the equation would be 11(6) + 15.
Hope this makes sense, don't hesitate to ask for clarification on a certain part of the answer.
Find the areas of the circle. Round your answers to two decimal places, if necessary.
Answer:
3.14 yd²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr²
Filling in the values, we find the area of this circle to be ...
A = 3.14×(1 yd)² = 3.14 yd²
Is the identity property the same as the simplify property?
Answer:
La propiedad de la identidad de 1 dice que cualquier número multiplicado por 1 mantiene su identidad. En otras palabras, cualquier número multiplicado por 1 permanece igual. El número permanece igual porque multiplicar por 1 significa que tenemos 1 copia del número. Por ejemplo, 32x1=32.

-2(x+1)(x-2) what is the y-intercept?
Answer:
The y-intercept is at 4.
Step-by-step explanation:
When trying to find the y-intercept, you want to substitute your x's with 0 as x must equal 0 for your y-intercept. This gives you -2(0+1)(0-2). From here, you want to simplify your parenthesis equations.-2(1)(-2) Then you want to solve which gives you 4.
if a cheetah runs 1 mile a second how many miles does he run in one minute
Answer:
The answer would be 60 miles.
Step-by-step explanation:
There are 60 second in a minute. If a cheetah runs 1 mile a second, the equation would be 1 mile X 60 seconds. 1x60=60.

-Oxygenated blood is pumped to the rest of the body via the aorta.
-Deoxygenated blood (blood that needs oxygen) coming from the body.
-Then is pumped to the right ventricle.
-Then is pumped to the lunges to get oxygen via the pulmonary artery,
-Oxygenated blood from the lunges flows into the left atrium via the pulmonary vein.
-Flows into the right atrium.
-Then is pumped into the left ventricle.
I'm very confident in this answer, but if it happens to be wrong, I'm sorry.

Find the value of x and then find the length of RT
RT =
X=
Answer:
x = 5, RT = 18
Step-by-step explanation:
[tex]\triangle MNL \sim \triangle SRT... (given) \\
\therefore \frac{MN}{SR} = \frac{NL}{RT}.. (c.s.s.t)\\ \\
\therefore \frac{84}{24} = \frac{63}{3x+3}\\ \\
\therefore \frac{7}{2} = \frac{63}{3x+3}\\ \\
\therefore 3x+3 = \frac{63\times 2}{7}\\ \\
\therefore 3x + 3 = 9\times 2\\
\therefore 3x + 3 = 18\\
\therefore 3x = 18 - 3\\
\therefore 3x=15\\
\therefore x = \frac{15}{3}\\
\huge \red {\boxed {\therefore x = 5}} \\ \\
\because RT = 3x + 3\\
\therefore RT = 3\times 5+ 3\\
\therefore RT = 15+ 3\\

Figure B is a scaled copy of Figure A.
Figure A
Figure B
What is the scale factor from Figure A to Figure B?
Greetings from Brasil...
Comparing the distances AB and A'B ', we notice that AB = 3 and A'B' '= 9.
We can say that:
AB · X = A'B'
3 · X = 9
3X = 9
X = 9 ÷ 3
X = 3
Thus, figure B is 3x larger than figure A
scale factor = 3x larger
Answer:
x=3
Step-by-step explanation:
AB = 3 and A'B' '= 9.

Pythagorean theorem
Answer:
8.7
Step-by-step explanation:
hypotenuse= 14 =c
a=11
b=x
a²+b²=c²
b²=c²-a²
b²=14²-11²
b²= 196-121
b²=75
b=√75=5√3=8.7 rounded to the nearest tenth
Final Answer:
x = 8.66
Step-by-step explanation:
formula: [tex]b=\sqrt{c^2-a^2}[/tex]
a = 11
b = x
c = 14
[tex]b=\sqrt{14^2-11^2}[/tex]
[tex]b=\sqrt{196-121}[/tex]
[tex]b=\sqrt{75}[/tex]
b = 8.66025
x = 8.66
rounded off to the nearest hundredths: 8.66

How do you use what you know about absolute value to add integers?
Please please help ASAP! Classify each angle!
Answer:
Acute Angles: ∠TLS, ∠SLT, ∠ULR Right Angles: --------- Obtuse Angles: ∠RLT, ∠SLU, ∠ULS, Straight Angles: ∠RLS, ∠TLU Not angles: ∠TRLStep-by-step explanation:
The lines intersect at point L, so all angles have a vertex (middle letter) L so there is no angle TRL
Straight angle is a line with dot-vertex, so the straight angles are ∠RLS and ∠TLU.
∠TLS is less than 90° then it is acute angle (∠SLT is the same angle). ∠ULR is vertex angle to ∠TLS, so it's also acute angle.
Two angles adding to straight angle mean that they are both right angles or one is acute and the second is obtuse. ∠TLS is acute so ∠RLT is obtuse (they adding to ∠RLS) and ∠SLU is obtuse (they adding to ∠TLU). ∠ULS is the same angle as ∠SLU.

In the diagram, line segment CD is the perpendicular bisector of line segment AB, and E is a point not on either line that is on the same side of segment CD as point A.
Is point E closer to point A, closer to point B, or the same distance from both points? Explain how you know.
Answer:
E would be closer to A
explanation:
if they were the same distance from both A and E it would be a point on the line CD, and if it was closer to E it would be on the other side of line CD.
i hope this is right :/
A plane traveled 360 miles each way to Athens and back. The trip there was with the wind. It took 3 hours. The trip back was into the wind. The trip back took 6 hours. Find the speed of the plane in still air and the speed of the wind.
Answer:
S=32.5
W=97.5
Step-by-step explanation:
S=speed of plane in still air
W=speed of wind
-----------------------------------------
3(S+W)=130
6(S-W)=130
-----------------------------------------
S+W=43.33333...
S-W=21.66666...
2S=64.999...
S=32.5(simplified)
-----------------------------------------
32.5+W=130
W=97.5
