Angles D and A are equal (from the statement bc the name of triangle starts with A and D)
Now set an equation of the angles so
45 = 5y -10
Add 10 on both sides
55 = 5y
divide by 5
y = 11
Answer:
<em>1. </em><em>B. $20</em>
<em>2.</em><em>C. 19%</em>
<em>3. </em>D. not here
Step-by-step explanation:
1. info we know
25+45+10+25+15+10 = 130
we need 20 more dollars
2. 25/130 x/100
cross multiply
2500/ 130x
divide
19 = x
3. same steps as last time
35/130 x/100
3500/130x
29%
He pays $24 interest
the percentage interest would be 24/300 ×100 = 8% interest
Because he hasn't cigarettes...
9x - 3(x + 2) + 7
Multiply the bracket by -3
(-3)(x)=-3x
(-3)(2)=-6
9x-3x-6+7
Answer: 6x+1
