35 pencils would cost $2.80,
$1.60 / 20 = $.08
Each pencil costs $0.08 each
.08 * 35 = 2.80
Answer:
b = 87°
Step-by-step explanation:
In order to answer this question, we need to utilise an important angle fact which is <em>angles in a quadrilateral add up to 360° </em>
Using the information we can set up an equation to find the value of b
→ Form equation
63 + 140 + 70 + b = 360
→ Simplify
273 + b = 360
→ Minus 273 from both sides isolate b
b = 87°
1. Recall the vertical line equation.
2. Plug in the x that we know.
3. Write down the final equation

Answer:
Step-by-step explanation:
Step-by-step explanation:
5:28^25 I think
6:keep the base multiply exponents
7:no because you would multiply the bases and keep the exponent the same
8:7 because 7 x 5= 35
1: 2 and 3 for the second part of it 2 and 5
2:7^30
3:54^3
4:Yes they are just flipped
