Answer:
-4y=40
y=-10
x-3(-10)=17
x-30=17
x=17+30
x=47
Step-by-step explanation:
Answer:
x=15
Step-by-step explanation:
This is a simultaneous equation
2x-3y=45 ------------------------------ equation i
x+y=10 -------------------------------equation ii
from equation ii
x+y=10
make x the subject of the matter
we have,
x=10-y
in equation i
substitute x for 10-y
2x-3y=45----------------------i
since x=10-y
we have,
2(10-y) - 3y=45
20-2y=3y=45
collect like terms
-2y-3y=45-20
-5y=25
divide both sides by -5
we have y=-5
substitute y for-5 in equation i
x+y=10
x+-5=10
collect like terms
x=10+5
x=15
therefore
x=15
Answer:
first calculate the area of the arch using:
O/360×πr2
O represents theta
second calculate the area of the circle using πr2
finally minus the answer gotten from the two different areas
thats how u get the area of the shaded area
To evaluate the answer of Harry:
8-(2+5)8-(2+5)
= -55
To evaluate the answer of Terry:
8-2+58-2+5
= 66
HH = -55
TT = 66
H-TH-T
5-65-5
= -65
