Answer:
x=8
Step-by-step explanation:
Triangle DCE is similar to EGF
CE/EF=DE/EG
Substitute
(8x-1)/21=(6x+3)/17
Cross multiply
(8x−1)*(17)=(6x+3)*(21)
136x−17=126x+63
Subtract 126x from both sides
10x−17=63
Add 17 to both sides.
10x−17+17=63+17
10x=80
Divide both sides by 10.
x=8
When they have no solutions, the lines are parlaell, or they have the same slope but different y intercept
example
3x+2y=2 and
3x+2y=4 are paralell
also
y=3x+2 and
y=3x+4 are also parlell, no solutions
infinite solutions are when they are the same line
they have the same slope and y intercept
to find out, simplify
3x+2y=4 and
6x+4y=8 are smae lien
also
y=3x+2 and
2y=6x+4 aer the same line
1 solution is when it is none of the above things
a normal thing, where the slopes are differnet
example
y=2x+2
y=3x+2
Answer:
60/100 and x/20 and x=12
Step-by-step explanation:
60 % of 20
60/100 = x/20
cross product
60 * 20 = 100x
divide by 100
1200/100 =x
12=x
Answer:60/100 = x/20 x= 12
hope it's right
Answer:
Is not correct. The product not always will be smaller.
Step-by-step explanation:
A fraction could increase a number if you multiply it.
If the numerator is higher to the denominator, it will increase it.
If the numerator is smaller to the denominator, it will decrease it.
<u>For example,</u>
10 x 4/3
For fraction multiplication, multiply the numerators and then multiply the denominators to get
10×4/1×3=40/3= 13,33
13,33 is higher than 10.
5 x 10/3
For fraction multiplication, multiply the numerators and then multiply the denominators to get
5×10/1×3=50/3
16,66 is higher than 5.
It does not have a mode
Mode: is the number that appears the most
in this situation, no number appears more than once
hope this helps
