First combine like terms ,
5/5x=9/5x
move the variable which will cancel out because it is the same
5=9 is no solution sorry if i’m wrong lol
Answer:
yes
if you solve the equation,
5x+15=7x-11
26=2x
x=26/2=13
Step-by-step explanation:
Answer:
-5 =x
Step-by-step explanation:
3^(x-1) = 9^(x+2)
Replace 9 with 3^2
3^(x-1) = 3^2^(x+2)
We know that a power to a power means the powers are multiplied
a^b^c = a^(b*c)
3^(x-1) = 3^(2x+2)
When the bases are the same, the powers have to be the same
x-1 = 2x+4
Subtract x from each side
x-x-1 =2x-x+4
-1 =x+4
Subtract 4 from each side
-1-4 =x+4-4
-1-4 = x
-5 =x
358,062 rounded to the nearest thousand is 358,00
Answer:
CU = 117
Step-by-step explanation:
Since we have similar triangles, we can use proportions. Put the small triangle sides over the large triangle side.
WC WD
----------- = -------------
WU WV
26 20
----------- = -------------
36x-1 110
Using cross products
26*110 = 20* (36x-1)
Distribute
2860 = 720x - 20
Add 20 to each side
2860+20 = 720x-20+20
2880 = 720x
Divide by 720
2880/720 = 720x/720
4=x
We need to find CU
CU = WU - WC
Substituting in what we know
CU = 36x-1 -26
Since we know x=4
= 36*4 -1 -26
144 - 27
= 117
