Answer:
The expression representing the total price of the truck including the sales tax is 1.07p
Step-by-step explanation:
The total price of the Truck can be calculated by adding the cost of the Truck to the sales tax of the Truck
From the question, the cost of the truck is $ p while the tax is 0.07p
So the total price of the truck will be;
p + 0.07p
= p( 1 + 0.07)
= p(1.07)
= 1.07p
Answer:
A: 7 + 3 (negative 4) (2)
Step-by-step explanation:
Just as a rule of thumb, whenever you multiply or divide one negative number and one positive number, the outcome is always negative. However, whenever you multiply or divide two negative numbers OR two positive numbers, the outcome is always positive.
Now, let's first convert all these words into simple mathematical expressions and then solve them:
A) "7 + 3 (negative 4) (2)" = 7 + 3 * (-4) * 2 = 7 + (-24) = -17
B) "Negative 2 Left-bracket 12 divided by (negative 3) Right-bracket" =
-2 * [12/(-3)] = -2 * (-4) = 8
C) "(15 minus 7) minus (9 divided by 3)" = (15 - 7) - (9/3) = 8 - 3 = 5
D) "Negative 5 Left-bracket 7 + (negative 14) Right-bracket minus 30" =
-5 * [7 + (-14)] - 30 = -5 * (-7) - 30 = 35 - 30 = 5
The only expression that produces a negative value is the first one, A.
Hope this helps!
Ok so for every 1 centimeter you get 10 millimeters. Meaning that if you multiply 20 * 10 you get 200 millimeters and if you multiply 10 * 10 you get 100. Now you subtract 200-100 and you get 100 millimeters.
