Answer:
1 apple= $0.4
Step-by-step explanation:
Let o=orange
Let a=apple
4o+5a=4
2o+3a=2.20
2o=2.20-3a
o=2.20-3a/2
Let's go balk to the the first equation
4o+5a=4
4(2.20-3a/2)+5a=4
4.4-6a+5a=4
4.4-a=4
-a=-0.4
a=0.4
Apple=$0.4
13. 3(x-6)-8=-2 (you have to plug in x-6 as x in the equation
3x-18-8=-2 (distribute 3)
3x-26=-2 (combine like terms)
3x=24 (subtract 26 to both sides)
x=8 (divide 3 to both sides)
14. -2(3(5y+5)=-4
-2(15y+5)=-4
-30y-10=-4
30y=6
y=1/5
15. (3x-5) +2x = 90
16. Let m be the number of minutes
0.75m+32 = 47
Using this equation you can find the number of minutes.
0.75m = 15 ( subtract 32 to both sides)
m= 20 (divide 0.75 to both sides)
Vera called 20 minutes beyond her allowed minutes.
Here I hope that this helped you out hon :)
-36/-31.5 = 1.1428571428571428571428571428571
-31.5/-27 = 1.1666666666666666666666666666667
-27/-22.5 = 1.2
-22.5/-18 = 1.25
Answer:
x = 14
Step-by-step explanation:
In the triangle O is the centroid.
Now, we know that the centroid divides the medians in the 2 : 1 ratio that means the distance from the centroid to the vertex and the distance from the centroid to the opposite side remains in 2 : 1 ratio.
So, from the given diagram we can write
⇒ 3x = 4x - 14
⇒ x = 14 (Answer)
