Explain why you should récord a 1 in the tens columna when you regroup in addition problem

1 answer:

8 0

You should write a 1 because I f what you add is 11, 12, 13, 14, 15, 16, 17, 18, or 19 there is a 1 in the front of the numbers so you must put a 1 but if the number was 76 the number in the front is 7 so you would put 7 on the tens column.

PLEASE IF U KNOW THE ANSWER PLEASE HELP ME

Answer:

34.93

Step-by-step explanation:

Ok, so using the formula for a trapezoid, you would get that Jim's garden's area is equal to 135.

Since each grass bag can cover 20m of the garden,

135/20=6.75

You would need seven bags because you can't buy 6.75 bags at a store.

Since each bag of grass seed is 4.99, 7*4.99 = 34.93.

I'm doing this in dollars, so I'm assuming that one pound is 100 cents or something like that.

Solve the system of equations.<br> – 9y + 4x – 11 = 0<br> - 3y + 10x + 31 = 0

Kruka [31]

value of x =-4 and value of y=-3

(-4,-3) is the solution of system of equations.

Step-by-step explanation:

We need to solve the system of equations

$-9y + 4x-11 = 0- 3y + 10x + 31 = 0$

Rearranging:

$-9y + 4x = 11\,\,\,eq(1)\\- 3y + 10x=- 31 = 0\,\,\,eq(2)$

Multiply eq(2) with 3 and subtract eq(2) from eq(1)

$-9y + 4x = 11\\-9y+30x=-93\\+\,\,\,\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,+\\----------\\-26x=104\\x=\frac{104}{-26}\\x=-4$

Putting value of x = -4 into eq(1)

$-9y + 4x = 11\\-9y+4(-4)=11\\-9y-16=11\\-9y=11+16\\-9y=27\\y=\frac{27}{-9}\\y=-3$

So, value of x =-4 and value of y=-3

(-4,-3) is the solution of system of equations.
