Answer:
y=5
x=10 and
z=2
Step-by-step explanation:
since they are equivalance then,
for
triangle ABC and triangle DFE
AB=DF,BC=FE and AC= DE
So, AB=DF
8y-20= 4y
or, y=5
Then, BC= FE
2x+5=x+15
or, x=10
and
AC=DE
3z+9=10z-5
or, z= 2

10 units earn a profit of 5 in 2 months
that means
1 unit earns a profit of 0.5 in 2 months
that means
1 unit earns a profit of 0.25 in 1 month
---
8 units earn a profit 8*0.25=2 in 1 month
8 units earn a profit of 3*2=6 in 3 months
The correct answer is 1:5 because if you take the ratio of 6:30 and reduce it by dividing both 6 and 30 by 3 then you get 1:5
Answer:
Step-by-step explanation:
When you add integers you have either positive integers or negative integers. When you add positive integers, you just add normal. When you have negative integers, you have to see if the the larger number is positive or negative that will tell you if your answer is either negative or positive. Then you turn the negative into a positive then change the addition sign to a subtraction sign then solve.
