Answer:
a.
b. $0.15 per can of pineapple
Step-by-step explanation:
a. 1. Here we need to make a variable () that represents the unknown cost of one single can of pineapple, then multiply by the total number of cans, which we are told is 44.
2. The second term is the cost of the 11 bottes of mayonnaise, which we know to be $2.89. We add this to the first term.
3. We know that the total of these two numbers should be equal to the total amount of money that Tom spent. This number will be the amount he gave the cashier ($10) MINUS the change the cashier gave back to him ($0.35)
4. Now that we have formed an equation, we just need to solve for .
Equation
Simplify parentheses on the right and subtract 2.89 from both sides.
Simplify on the right side again to find 6.76, then divide both sides by 44.
Simplify and give this value units ($) to find your final answer to question b.
Answer: -5.125
Step-by-step explanation:
Let X be the "number."
The sum of 3.25 and twice a number is -7.
3.25 + 2X = -7
2X = -10.25
X = -5.125
Answer:
to the nearest tenth.
Step-by-step explanation:
Recall the mnemonics SOH.
This means that;
From the diagram, the side opposite to angle x is 10ft and the hypotenuse is 12 ft.
We substitute the values to get;
Take the sine inverse of both sides
to the nearest tenth.
Answer:
15x - y = - 126
Step-by-step explanation:
will make it simple and short
first we need to find the slope (m) first in order to get the equation
given: (-8,6) (-9,-9)
y2 - y1 -9 - 6
Slope = m = ----------- = ------------------ = 15
-x2 - x1 -9 - (-8)
so the equation of the line using point (-8,6) and slope 15 is y - 6 = 15( x + 8)
y - 6 = 15x + 120
using the form equation Ax + By = C, 15x - y = -120-6
therefore... 15x - y = - 126 <em>is the answer</em>
Answer:
C
Step-by-step explanation:
This is because 30d would be multiplying whatever the cost by 30, however with 0.3d you are taking 0.3 or 30% off of the whole number.
