Answer:
D
Step-by-step explanation:
(1/7)^(x)=A^(-9x)
(1/7)^(x)=(A^(-9))^x
A^(-9)=1/7
A=(1/7)^9
-50 - (-221) = 171
This is because subtracting a negative number is like adding a positive version of that instead. For a more simple example:
5 - (-2) = 7 or 5 + 2 = 7
Answer:
B. 2800 sq mm
Step-by-step explanation:
Given the following data;
Length = 80 mm
Width = 70 mm
Area of rectangle is given by the formula;
Area of rectangle = length * width
Substituting into the formula, we have;
Area of rectangle = 80 * 70
Area of rectangle = 5600 mm²
Since the paper (area of rectangle) was halved, we would divide by 2;
Area of each half = 5600/2
Area of each half = 2800 sq mm.
Answer:
d<84
Step-by-step explanation:
Let's solve your inequality step-by-step.
d
12
−6<1
Step 1: Simplify both sides of the inequality.

12
d−6<1
Step 2: Add 6 to both sides.

12
d<7
Step 3: Multiply both sides by 12.
12*(
