Answer:
h = 6
Step-by-step explanation:
Given the 2 equations
- 3x + 4y = - 30 → (1)
9x + 5y = 39 → (2)
We require the value of the x- coordinate at the point of intersection, thus require to eliminate the y- term from the equations
Multiply (1) by 5 and (2) by - 4
- 15x + 20y = - 150 → (3)
- 36x - 20y = - 156 → (4)
Add (3) and (4) term by term thus eliminating y
- 51x = - 306 ( divide both sides by - 51 )
x = h = 6
Answer:
20% increase
Step-by-step explanation:
All you have to do is divide 72 by 90n and it will give you .8, move the decimal two places to the right to give you 80 and subtract 80 from 100 to get 20

Days : 1 2 3 4 →→→→→→D(X axis)
Rent a Truck: 34 50 66 82→→→→→→R(Y axis)
As you can observe from number of Days and Amount to rent a truck , if you rent for a day the price being $ 34 and with increase in Day the rent increases by $ 16.
Plotting the point on graph , found that these points are collinear.
So, we can Represent this relation between days and Rent in equation of two variables representing a line.
Two point formula of line:
→→Equation of line passing through two points
So , line representing Days and rent is :
So, the rule representing Days and Rent is: 16 D - R + 18=0
...............................................................................................................................................
The answer is 18
If you subtract 47-29=18
Then if you subtract 47-65=18 the pattern is to add 18
Answer:
The required equation is 3y=36 and the tape diagram is shown below.
Step-by-step explanation:
Consider the provided information.
We need to write a multiplication equation that has a solution of 12.
3y=36
We know we have to split 36 into three equal groups, so we have to divide by 3 to show this algebraically.
3y÷3=36÷3
y=12
Now check this with the help of tape diagram as shown.
Consider the figure 1.
This represents if 36 had to be split into three groups, how big would each group be?
By the tape diagram we concluded that the value of y is 12.
7 by 2 for each blanket. If you split 28 into 2 sheets, its 14, sooo.
