Answer:
Check the attached graph for correct match.
Step-by-step explanation:
Graph of the given choices are not given but we can still solve this problem.
Given equation is 15x-12y=60.
Which is linear equation so we need at least two points to get the graph.
We are free to select any random number of x then plug that into given equation to find other variable.
Let's use x=0
15x-12y=60
15*0-12y=60
0-12y=60
-12y=60
divide both sides by -12
y=-5
Hence point is (0,-5)
Similarly plug y=0
15x-12y=60
15x-12*0=60
15x-0=60
15x=60
divide both sides by 15
x=4
Hence point is (4,0)
Now graph both points then join them by a straight line.
Any graph given in the choices which match with attached graph will be the answer.
Check the attached graph for correct match.
Answer:
n = 20
Step-by-step explanation:
n/2 - 9 = 1
Add 9 to each side
n/2 -9+9 = 1+9
n/2 = 10
Multiply by 2 on each side
n/2*2 = 10*2
n = 20
First you can see that there are 3 numbers 160,125,and 40 you can add 125 and 40 because they are both checks so then after you add you get $165 in checks do you then subtract $125 which is how much she put in and you get $40. So, she has $-40
In her bank account meaning her back scout was decreased by $40.
Answer:
52.5 kg ANS
Step-by-step explanation:
Weight of a pile of sand = 90kg
Ratio of weight of sand in three bags = 2:3:7
Let the weight be 2x kg, 3x kg, 7x kg respectively A.T.Q.
= 2x + 3x +7x = 90
= 12x = 90
= X= 90/12
= X = 7.5 kg
Weight of sand in medium bag =
= 3 × 7.5
= 52.5 kg ANS
I hope this answer is correct
