Answer:
-5x+173
Step-by-step explanation:
x+4x+7 (sum of the 2 angles that you know)
5x+7
180-5x+7
-5x+173
Answer:
4x+4=-3x-10
4x+3x=-10-4
x= -14
Step-by-step explanation:
Answer:
1.a and 2.b.
Step-by-step explanation: let's say the area=2. if you multiply by 2, it gets bigger. if d<1, it's like dividing by a number, meaning that the area becomes smaller.
Step-by-step explanation:
Since all side lengths of smaller squares are equal, we have


Since length of AB is twice of the side length of smaller squares,

The mirror cost when the cpi is 211, to the nearest cent is $187.69
<h3>Ratio and proportion</h3>
Fraction is expressed as a ratio of two integers. For instance a//b is a fraction where a and b are integers.
From the given question, a full-length mirror cost $144.99 when the cpi was 163, hence;
$144.99 = 163 cpi
In order to determine the mirror cost when the cpi is 211, we will write;
x = 211 cpi
Find the ratio;
144.99/x = 163/211
163x = 30592.89
x = 30592.89/163
x = 187.69
Hence the mirror cost when the cpi is 211, to the nearest cent is $187.69
