The degree of a line is 180, so..
Put it into an equation form: 5x + 75 = 180
1st combine like terms by subtracting 75 from 180
now your equation looks like this: 5x = 105
next you divide 5 from both sides, 105 divided by 5 is 21, so your answer is: x=21
I hope this helps!♥
Step-by-step explanation:
- 2x + 4 + 3 = -4
-2x+7= -4
-2x= -4-7
-2x= -11
x=-11/-2
x=11/2
x=5.5 (if u want the answer in decimal form)
Answer:
Malcolm's maximum speed is
Ravi's maximum speed is
Step-by-step explanation:
Notice that this is a problem with two unknowns: the max speed of Malcolm (let's name this "M"), and the max speed of Ravi (let's name this R). So we need to build two equations with them, based on the information given.
Equation 1: based on the phrase "The average of their maximum speeds was 260 km/h" we write the equation for average (addition of both speeds, divided by 2, equal 260 km/h:
Equation 2; based on the phrase: "If doubled, Malcolm's max speed would be 80 km/h more than Ravi's max speed"
We can now use for example substitution to solve the system of equations
From the second equation we created, we can solve for R in terms on M:
and use it as substitution in the first equation:
And now use this value of M in the substitution equation to solve for R;
Answer:
180 cm2
Area of a polyhedron:
15(=base)x12(=height)
=180cm2
btw parallelogram is a 2D pic how you can come out a ''base'' and ''height''? It should be called a polyhedron. Your question is weird.
If so, your ''area of parallelogram'' is 15cm2 since your question is hecking weird.
Btw it's 15cm2 not 15
