Answer:

x=88° a=+3 b=4a-3

Step-by-step explanation:

as triangles ADE and BCE are congruent by sss axiom

so correponding angles are equal

i.e<AED = <BEC

and <DAE =90-60

=30°

so

62°+x+30°=180°

therefore x=88°

1. The county fair charges $1.50 per ticket for the rides. Jermaine bought 20 tickets for the rides and spent a total of $48.75
MAVERICK [17]

Answer: Our variable be z for fair admission and our required linear equation will be

\$1.50x+z=\$48.75

Explanation:

Since we have given that

Cost per ticket for the rides =$1.50

Total amount she spent = $48.75

Let the total cost be y

Let the number of ride tickets be x

<u>a) Define your variable:</u>

Let the amount spent on fair admission be z

<u>b) Write a linear equation that can be used to determine the cost for ride tickets and fair admission:</u>

Our required equation will be

\$1.50x+z=\$48.75

Here, number of ride tickets = 20

So,

20\times 1.50+z=48.75\\\\30+z=48.75\\\\z=48.75-30=18.75

So, the cost for fair admission = $18.75

Y=12+2x
y represents the number of pieces she now knows, x represents the number of weeks she has taken lessons, 2 is the slope (the number of pieces she'll learn each week), and 12 is the y intercept (the number of pieces she knew before taking lessons).

To solve the equation for 11 weeks, we replace x with 11.

2×11+12= 24
y=24
