Levar is four years older than Danny. Together, their ages add up to 60 . Write an equation to find how old Danny is , using ? To represent his age.
Answer:
2x+4=60

Jade wants to verify that the expression 5(3x – 6) is equivalent to 15x – 30. She substitutes 2 into each expression and evaluates each one. How will she know if 5(3x – 6) is equivalent to 15x – 30?
They are equivalent if the two values are the same.
They are equivalent if the value for 5(3x + 6) is greater.
They are equivalent if the value for 15x + 30 is greater.
They are equivalent if one value is negative and the other value is positive.
Answer:
They are equivalent if the two values are the same.

Answer:
(x, y) = (-4, 4)
Step-by-step explanation:
See the attachment for the graphs.
We assumed your second equation is -2x+y=4.
The solution is (-4, -4).

Answer:
A. Yes
B. No
C. Yes
Step-by-step explanation:
A. 90 divided by -9 equals -10. So -10+10=0
B. -10 times -9 equals 90. 90+90=180
C. -90 dived by 9 equals -10. Subtracting a negative number is equal to adding it so -10 - (-10) = 0

Find the Distance between the points (-6,5)and(8, -3)
Answer:
[tex]d=16.1245[/tex]
Step-by-step explanation:
Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in your 2 coordinates into the formula to find distance d:
[tex]d=\sqrt{(8-(-6))^2+(-3-5)^2}[/tex]
[tex]d=\sqrt{(8+6)^2+(-8)^2}[/tex]
[tex]d=\sqrt{(14)^2+64}[/tex]
[tex]d=\sqrt{196+64}[/tex]
[tex]d=\sqrt{260}[/tex]
[tex]d=16.1245[/tex]

Briefly explain how to convert a fraction to its decimal
form.
Answer:
you just divide
Step-by-step explanation:
Just divide the top of the fraction by the bottom, and read off the answer!
Answer: So what my teacher always told me to do was act like a fraction was a tree. The tree always falls to the left which then outs the fraction as a division problem. You solve the division problem
Step-by-step explanation:
Ok so for example, lets use [tex]\frac{1}{2}[/tex]. Drawing it as a tree it then falls to the left. Therefore it becomes 1 ÷ 2. So 2 can not go into one therefore you need to put a decimal point at the top and add a zero behind the 1 under the bar. The 1 then becomes a 10, therefore 2 can go into 10 5 times. However the answer is not 5. You have to remember to bring the decimal point that you placed before the 5. In conclusion hte answer is .5 . This may be confusing because I am not able to include any photos but hopefully you'll get the point.

Why can you not combine the 8a2 and 8a?
Answer:
you can't add or subtract numbers that don't have the same variable or the same exponent
Answer:
You cannot combine the terms [tex]8a^2[/tex] and [tex]8a[/tex] because they are not like terms, which are terms that consist of both the same power, and the same variable. Seen with the two terms given, they both share the same variable ([tex]a[/tex]), but not the same power ([tex]2[/tex]).

Danny is selling cornhole boards to raise money for a local charity. He rents a booth at the state fair for $250. He sells the boards for $45. It costs him $20 to make each board. How many boards must Danny sell to break even for the cost of renting a booth?
Answer:
10
Step-by-step explanation: because if you get 45$ for breaking 1 and lose 20$ for paying for it you will just get 25$ for breaking each board
