- a (30)
fig 3 would take 18 triangle
fig 4 would take 30 small triangles
if its wrong i am sorry
To solve this, you will have to set up your equation as fractions:
X is to 4 as 4 is to 4+3, or 7
X/4 = 4/7
You will then cross multiply
7x = 4•4
7x = 16
Divide.
X = 2.285714...
Round to the nearest hundredth.
2.29
Answer:
Step-by-step explanation:
Let the age of Seema be x and her father be 3x
After 12 years,
Age of Seema=x+12
Age of father=3x+12
Now we have,

Again,
Present age of her father=3x=3×12=36
Hence, the present age of Seema is 12 and her father is 36.
You first have to set up the two equations. Y is equal to the total number of gallons in a tank and x is equal to the number of hours the tanks are filling.
Since the two equations both equal y I can make them equal each other. I then solved for x as you see and got -4.
Once I found my x value I now needed to find my y. You only needed to chose one equation to solve for y, so I decided to do the first one. I plugged in -4 where my x value currently was and solved for y. I got 2.
If you have any questions please comment!! Hope this helps!!
We need to divide for this. Since there are 12 months in a year, we divide his yearly salary by 12.
270,920.64÷12=22,576.72
So, Mr.Castillo's monthly salary is $22,576.72.
