Both planes have a speed of 340 miles per hour and 510 miles per hour, respectively.
What is equation?In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical statement made up of two expressions joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.
Here,
Let tc be the time of commercial jet and tp be the time of private airplane.
Let vc be the speed of commercial jet and vp be the speed of private airplane.
Let dc be the distance of commercial jet and dp be the distance of private airplane.
now,
dc=dp
vc=vp+170
vc*tc=vp*tp
(vp+170)*1.2=vp*1.8
(vp+170)*2=vp*3
2vp+340=3vp
vp=340 miles/hour
vc=340+170
vc=510 miles/ hour
The speed, in miles per hour, of both airplanes is 340 miles per hour and 510 miles per hour.

What two numbers multiplied equal 6 but added together equal -7?
Answer:
-6 and -1
Step-by-step explanation:
let's suppose there are two numbers x and y so that it that works that would give the following equations
[tex]x*y=6 \\ x+y =-7[/tex]
now let'S rewrite the first to the form y =
[tex]y=\frac{6}{x}[/tex]
and plug that into the second one
[tex]x+\frac{x}{6} = -7|*6\\6x+x=-42\\7x=-42|:7\\x=-6[/tex]
use that to find out what y is
[tex]-6+y=-7|+6\\y=-1[/tex]
you can check that with the first equation
write a equation in the form y= mx or y= mx + b to represent the relationship between the independent and dependent qualities?
Answer:
y = 10x
Step-by-step explanation:
Independent variable (x) = time (minutes)
Dependent variable (y) = distance (feet)
The line passes through the point of origin (0, 0), which means it represents a proportional relationship. Therefore, the equation would be in the form of y = mx. Where,
m = slope = y/x
Using any point on the line, say (5, 50),
m = 50/5
m = 10
To write the equation, substitute m = 10 into y = mx
Thus:
y = 10x
Explain why triangles with 3 congruent parts aren’t necessarily congruent.
Answer:
SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

Michael is building a skateboard ramp He cannot decide how long the ramp should be so he draws the blueprint below. Michael draws a vertical line in the big triangle AAGH to form the AABC Michael determines the slope of both triangles to find out which ramp will be steeper
Answer:
The answer is below
Step-by-step explanation:
The slope of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given by:
[tex]slope(m)=\frac{y_2-y_1}{x_2-x_1}[/tex]
The slope of triangle ABC is gotten by finding the slope of line AC. Line AC passes through the point A(15, 1) and C(10, 3). The slope of triangle ABC is given by:
[tex]slope\ of\ triangle\ ABC=\frac{3-1}{10-15}=-0.4\\[/tex]
The slope of triangle AGH is gotten by finding the slope of line AH. Line AH passes through the point A(15, 1) and H(0, 7). The slope of triangle AGH is given by:
[tex]slope\ of\ triangle\ AGH=\frac{7-1}{0-15}=-0.4\\[/tex]
Since both triangles have the same slope, therefore their steepness is the same.

Which expressions are equivalent to z ⋅ 3 1/3
select all that apply!!!!!!!!!!!!!!
3z+1/3
6z−2/3z−3z+z
z ⋅ 4−2/3
z(4−2/3)
z(1/3+3)
Answer:
Options 2), 4 , and 5 are CORRECT
Step-by-step explanation:
Notice that z * 3 1/3 = z * (3 + 1/3) = z * (9/3 + 1/3) = z * 10/3 = 10/3 z
1) The first option is not good'
2) 6 z - 2/3 z - 3 z + z = 4 z - 2/3 z = 12/3 z - 2/3 z = 10/3 z So this option is CORRECT
3) z * 4 - 2/3 is not good since 2/3 is not multiplied by z
4) z ( 4 - 2/3) = z (12/3 - 2/3) = z * 10/3 so this one is CORRECT
5) z (1 / 3 + 3) = z ( 1/3 + 9/3 ) = z (10/3) So this one is also CORRECT
