Just split it in to three rhombuses and then split each rhombus in half.
You will now have six triangles
Divide 1 3/4 into 15. I like to change my fractions into decimals, so I will be using the decimal form of 1 3/4, which is 1.75
15 ÷ 1.75 = 8.571
Since there is still some left over, you would need to add one more roll. Therefore, you would need 9 rolls.
There are 9,000 markers in total
750 x 12 = 9,000
Answer:
The two numbers are 7 and 11.
Step-by-step explanation:
x represent the first number.
y represent the second number.
x + y = 18
x - y = 4
2x = 22
x = 11
x - y = 4
(11) - y = 4
y = 7
SYSTEMS OF EQUATIONS. A system of equations is a collection of two or more equations with a same set of unknowns. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system.
