Answer:
4.8
Step-by-step explanation:
6.4×1/4=1.6
6.4-1.6=4.8
Answer:
y = 2
Step-by-step explanation:
x + 5y - 10 = 0
X = 4y - 8
since x is given as = 4y - 8 we can use this in first equation
replace x with 4y - 8
x + 5y - 10 = 0 ➡ 4y - 8 + 5y - 10 = 0 add like terms
9y - 18 = 0 add 18 to both sides of the equation
9y = 18 divide both sides by 9
y = 2
The measure of <COD and <POT are 43 and 43degrees respectively
The point where two lines meet or intersect is known as an angle:
Is <COP and angle TOD are vertical angles, this means that they are equal i.e.
Given that:
<COP = 11x - 17
<TOD = 9x + 11
Equate both expressions
11x - 17 = 9x + 11
11x - 9x = 11 + 17
2x = 28
x = 28/2
x = 14
Get <COP
<COP = 11x - 17
<COP = 11(14) - 17
<COP = 154-17
<COP = 137 degrees
Since <COP = <TOD, hence <TOD = 137 degrees
Calculate <COD:
<COD + <TOD = 180
<COD + 137 = 180
<COD = 180 - 137
<COD = 43 degrees
Also <POT = <COD = 43degrees(vertically opposite angles)
Hence the measure of <COD and <POT are 43 and 43degrees respectively

Answer:
15
Step-by-step explanation:
Plug in 3 as x:
3x + 6
3(3) + 6
9 + 6
= 15
So, the simplified expression if x = 3 is 15
Answer:
b^2√30b
Step-by-step explanation:
√30b^5 - Original
Break down the radical with its factors (factor tree)
√3*2*5*b*b*b*b*b
See what perfect squares you can take out (Can take out four b terms) You cant take out any perfect squares involving 30 since there are no perfect squares
b^2√3*2*5*b
b^2√30b
