Answer 1
Answer:

Answer:

Step-by-step explanation:

5x + 6 = 3x + 10

2x + 6 = 10

2x = 4

x = 2

m<DST = 3(2) + 10 = 6 + 10 = 16

m<DSE= 5(2) + 6 = 10 + 6 = 16

The measure of RST can be represented by the expression (6x + 12)°. What is mRST in degrees?

156°

Answers

The measures of RST in degrees is 120degrees

Lines and angles

From the given diagram, the following expression is true

<RST = 78 + 3x - 12

Since <RST = 6x +12, hence;

6x + 12 = 66 + 3x

3x = 54

x = 18

Find the measure of <RST

<RST = 6(18) + 12
<RST = 120degrees

Hence the measure of RST in degrees is 120degrees

Answer:

The measure of angle RST is 120\°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

m<RST=(6x+12)\° -----> equation A

m<RST=78\°+(3x-12)\° -----> equation B

equate equation A and equation B

(6x+12)\°=78\°+(3x-12)\°

6x-3x=78\°-24\°

3x=54\°

x=18\°

The measure of angle RST is equal to

m<RST=(6(18)+12)=120\°

Connecting a DVD player to a television set requires a cable with special connectors at both ends. You buy a six-foot cable for $15.50 and a three-foot cable for $10.25. Assuming that the cost of a cable is the sum of the cost of the two connectors and the cost of the cable itself, what is the cost of a four-foot cable?

Answers

so a 3 foot cable is10.25
a 6foot cable is 15.50
so
x=cost per foot
y=cost of special connectors
3x+y=10.25
6x+y=15.50
make first equation negative and add to the first
3x=5.25
divide both sides by 3
1.75=x
so it costs 1.75 for a foot of cable

subtitue into first equation
3(1.75)+y=10.25
5.25+y=10.25
subtract 5.25 from both sides
y=5 dollars=cost of special so
4x+y=4(1.75)+5=7+5=$12

so the cost of a 4 foot cable is $12
