Julie has three boxes of pens. The diagram shows expressions for the number of pens in each box. Look at these equations.
vovangra [49]

Answer:

a = c + 16

Step-by-step explanation:

a = b + 12

b = c + 4

Solve for b in the first equation.

a = b + 12

a - 12 = b

Put b as a - 12 in the second equation and solve for a.

a - 12 = c + 4

a = c + 4 + 12

a = c + 16

Suppose Ken has 25 coins and nickels and dimes only and has a total of a $1.65 how many of each coin does he have?
nikklg [1K]
x-\ number\ of\ nickels\\
y-\ number\ of\ dimes\\\\
x+y=25 \ \ \ | x=25-y\\
0.05x+0.1y=1.65\\\\
0.05(25-y)+0.1y=1.65\\\\
1.25-0.05y+0.1y=1.65\\\\
1.25+0.05y=1.65\ \ \ | subtract\ 1.25\\\\
0.05y=0.4\ \ \ \ \ | divide\ by\ 0.05\\\\
y=8\\\\
x=25-8=17\\\\
There\ are\ 17 \ nickels\ and\ 8\ dimes.

......... my algebra....
dsp73

The graph represents a function but the table does not. The reason for this is that one input value (70) in the table is associated with two output values (54.6 and 53.11), which is a sure sign that we do NOT have a function here.

What is the measure of ABC and please show me how to do it
oksano4ka [1.4K]
Arc length from A to C (red line) is the given inside angle times 2, so AC = 50*2 = 100 degrees.

A full circle is 360 degrees, so arc ABC (blue line) would be 360 - 100 = 260 degrees.

The answer is D.
