Answer:
Luke has 13 marbles
Step-by-step explanation:
t = number of marbles Tom has
l = number of marbles Luke has
t = 2l
t+l = 39
Substitute t = 2l into the second equation
2l + l = 39
Combine like terms
3l = 39
Divide by 3
3l /3 = 39/3
l = 13
Luke has 13 marbles
Tom has 2 * 13 = 26 marbles
Answer:
h = 2
Step-by-step explanation:
you know the original rectangle [h = 10, w = 15]
1. The height of 15 inches turned to 3 inches by diving by 5
2. You have to do the same with the height too!
3. 10/5 = 2
The new height is 2 inches.
1) What left
*Obs: remember that left at least 42 dollars. In other words, the left over is equal or more than 42 dollars.
2) At the beginning
Letter C
Answer:
(1, 3 )
Step-by-step explanation:
To find a solution to the equation.
Rearrange making y the subject by subtracting 6x from both sides
Given
6x + y = 9, then
y = 9 - 6x
Substitute any value of x into the equation and solve for y to obtain a solution
x = 1 → y = 9 - 6(1) = 9 - 6 = 3
Thus (1, 3) is a solution to the equation
So you need to know the area of patio in cm, so you need to caculate area and than convert.
4 x 5 = 20 m
20 m = 200000 cm
once you know area, you need to know the area of bricks.
9.5 x 20 = 190
Than divide patio area by brick area
200000 divide 190 = 1052 .63
since there cant be 1052.63 bricks, just round up to 1053.
so 1053 bricks are required for this patio.
Hope this helped!
