Answer:
98
Step-by-step explanation:
Subtract 14 from both sides (14-14 and 28-14)
The equation is now 1/7x=14
From here you have to get rid of the denominator of 1/7x so to cancel it out you must multiply both sides by 7.
1/7x · 7 = 1x
14 · 7 = 98
You then have the answer which is x = 98
2x+10 x + 3
------------ = --------------
10 4
4(2x+10) = 10(x+3)
8x + 40 = 10x + 30
2x = 10
x = 5
AE =2x+10 = 2(5) +10 = 20

Synthetic division work with the coefficient of the given polynomial expression
We have
-15 -16 84 -17 -9 -15
and the divisor is:
x - ⁸/₅ = 0
x = ⁸/₅
Refer to the diagram below for the steps of synthetic division
Start by multiplying the first coefficient by the divisor, write the answer under the second coefficient, and then add the two values.
Repeat the steps until we use up all the remaining coefficients
The final values are the coefficients of the quotient and the last value is the reminder
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
Answer:
Angle BOC = 28; Angle AOB = 21
Step-by-step explanation:
Because angle AOC = AOB + BOC you can set the equation:
2x+10 + 4x-15 = 49
<solve for x>
6x - 5 = 49
6x = 54
x= 9
<plug in x for the angles>
BOC = 2(9) +10 = 28
AOB = 4(9) - 15 = 21
