Use proportions for all of them, for #1 use the proportion 12/30 = 9/a based on corresponding sides and then cross multiply. a=22.5 For #2 use the proportion y/35 = 64/40 based on corresponding sides and then cross multiply, y=56 For #3 use the proportion 42/? = 54/36 and then cross multiply, ?=28
Answer:
a no solution
b is all real numbers
c x=12
Step-by-step explanation:
a has no values of x that make it true
b any value of x makes it true
c simplify both sides of the equation then isolate x

Answer:
<h2>The slope is 2</h2>
Step-by-step explanation:
Step one:
we are required to find the slope of the given data points
A(4,6) B(5,8)
hence the x and y values correspond to
x1=4
y1=6
x2=5
y2=8
Step two:
Required is the slope which is
slope= y2-y1/x2-x1
Slope=8-6/5-4
Slope= 2/1
<em><u>Hence the slope of the ordered pair is 2</u></em>
Answer:
20 pizzas.
Step-by-step explanation:
40% = 8
1% = 8 ÷ 40 = 0.2
100% = 0.2 x 100 = 20
