e)
Ok, so we need to set up a system of equations.
x + y = 19, where x is notebooks and y is pencils
2.2x + 1.09y = 30.70. You use the coefficient for individual prices and the total for the total given.
2.2x + 2.2y = 41.8 (multiply for elimination later)
2.2x + 1.09y = 30.7
1.11y = 11.1
y = 11.1/1.11
y = 10
Now we use the substitution method in x + y = 19
x + 10 = 19
x = 9
9 notebooks and 10 pencils
Answer:
Picture below
Step-by-step explanation:
● 5/2 is 2.5 so just divide the space between 3 by 2
● for 1/3 divide the space between 0 and by 3
Answer:
reflection and rotation
Step-by-step explanation:
Answer:
X ≤ 6
Step-by-step explanation:
3x + 9 ≥ 5x - 3
3x + 9 ≥ 5x - 3
Collecting like terms we have;
3X - 5x ≥ -3 -9
-2x ≥ - 12
X ≤ -12/-2
X ≤ 6
