Answer:
B. 3 divided by eight
Step-by-step explanation:
3/8 means 3 divided by 8
A fraction bar is division
The first step in solving the problem is to distribute the 8. We know this because of the system or order of operations as well as the distributive property.
8(2+7c)=-19
16+56c=-19
The next step in solving is to isolate the variable, which we can do by performing the opposite operations of the values
16+56c=-19
-16 -16
56c=-35
/56 /56
c=-35/56
Finally, we should put our equation in simplest form.
c=-35/56
c=-5/8=-.625
Using the math above, we can see that the value of the variable is -5/8 or -.625.
Answer:
22,500
Step-by-step explanation:
10% of 225,000 = 22,500
A
a) y+6x=5 if x= -1 then y+6(-1)=5 then y = 11
b) same thing if x = 3 then y+6(3)=5 y+18=5 subtract both sides by -18 and leave y on left then add 5+(-18)= 13 then y=13
B same as above
question (a) asks you to solve for y because x is -2
(b) asks you to solve for x because y is known
3x+2y=-6 if y = 3 you write 3x+2(3)=-6 3x+6=-6 move the +6 over to right side by subtracting 6 from both side 3x=-6 + -6 so 3x=-12 to get rid of the 3 and only leave the x you want to divide both side by 3 then x= -12/3 then the answer would be x=-4
Idk brooks srry, i would try asking google or something
