1000 g boxes costing 19.50
Step 1: set equations equal to eachother
2x+2=x-1
which equals to x=-3
so the answer is one.
Y = 360x + 120.
The y-intercept would be at (0, 120), as at year 0 or x=0, the weight is 120 kg.
If it increases every year by 360 kg, it would be noted in how many years it has been by 360x.
Answer:
a. yard
b. 1.2 feet
Step-by-step explanation:
a. Jackie cut a 2-yard spool into 5 equal length of ribbon.
We will divide 2 yard by 5 = 2 ÷ 5 = yard
5 units = 2 yard
1 unit = yard
Check : + + + + = = 2
b. Length of each ribbon in feet
Since 1 yard = 3 feet
therefore, 2 yard = 3 × 2 = 6 feet
6 feet in to 5 equal part = 6 ÷ 5
= 1.2 feet
check : 1.2 + 1.2 + 1.2 + 1.2 + 1.2 = 6.0 feet
Answer:
x = 25/2
y = 3/2
Step-by-step explanation:
x = 7y + 3
9y - x = 1
9y- (7y + 3) = 0
2y - 3 = 0
2y = 3
y = 3/2
9(3/2) - x = 1
27/2 - x = 1
-x = -25/2
x = 25/2
