2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
Answer:
A= y= -2x+7.
B= y= -
x+ 6
Step-by-step explanation:
The linear equation is y=mx+b
A= y= -2x+7.
-2 represents he slope and 7 represents the y intercept.
B= y= -x+ 6
- is the slop and 6 is the y intercept.
Hope this helps :)
Answer:
A^2 means a*a
Step-by-step explanation:
A^2 = 5^2=5*5=25
3a^2=3*5^2=3*25=75
A^2+7=5^2+7=25+7=32
Answer:
1. x = 2
2. x = 5
3. x = 8
4. x = 28
5. x = 13
6. x = 11
7. x = 0
8. x = 72
9. x = 6
10. x = 38
Step-by-step explanation:
hope that helps!
1. subtract 6 on both sides
2. add 3 on both sides
3. divide both sides by 2
4. multiply both sides by 2
5. add 8 on both sides
6. subtract 9 on both sides
7. add 5 on both sides
8. multiply both sides by 6
9. divide both sides by 4
10. add 18 on both sides
Answer: 7.3
Step-by-step explanation:
Do the parentheses first!
4-7= -3
Then, multiply -3 by 2
-3×2= -6
Next,
-6-6.7= -12.7
Then, add -12.7 to 20
-12.7+20=7.3
Your answer is 7.3
