Explanation:
The given <em>expression</em> is not an <em>equation</em>. There is nothing that can be <em>solved</em>.
___
An equation has an equal sign between its left side and its right side. Solving it means finding a value for the variable (or variables) such that the equation is true.
For example, we might have ...
5n +1 = 1
Your familiarity with math facts means you know that ...
0 +1 = 1
In order for the term 5n to have a value of 0, the value of n must be 0 in this equation. The solution to 5n+1 = 1 is <em>n = 0</em>, because 5×0 + 1 = 1 is a true statement.
___
An <em>expression</em> can be evaluated. To do that, put the value you want the variable to be every place you see the variable, then do the arithmetic.
To evaluate 5n+1 for n=6 we put 6 in place of n:
5×6 +1
Doing the arithmetic, we get ...
= 30 +1 = 31
The value of 5n+1 for n=6 is 31.
Number two is proportional just do Y over X y/x meaning divided all the y’s over the x’s so 25 divided by 5 30 divided by 6 35/7 40/8 they all equal 5 so it’s proportional
number three isn’t proportional when you do y/x they all come out differently so you do y2-y1 over x2-x1 16-4/4-2 16-4=12 4-2=2 then you divided 12/2 that equals 6 you do that again but with the next numbers but they don’t equal so it’s no equation no constant
Answer:
a₁ = 18
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₃ = 10 and a₅₁ = - 182, then
a₁ + 2d = 10 → (1)
a₁ + 50d = - 182 → (2)
Subtract (1) from (2) term by term to eliminate a₁
48d = - 192 ( divide both sides by 48 )
d = - 4
Substitute d = - 4 into (1) and evaluate for a₁
a₁ + 2(- 4) = 10
a₁ - 8 = 10 ( add 8 to both sides )
a₁ = 18
Step-by-step explanation:
So first you want to multiply the percentage of the yellow balls by three to get the amount of "300%" which is 300 balls. Munising 100 by 40, you get 60% is white. So multiply that by three also. So for Yellow, you have 120 balls, and for white, you have 180. So you take 120 and take 20% of it, and it would give us 24. You take the 180, and that one gives us 144. So if you add 144 and 24, Sally's team found 168 balls out of 300.
hope this helps
Answer:
So add all the numbers together 0.75 + 0.75 = $1.50
Then $1.50 + $1.09 = $2.59
Next $2.59 + $0.68 = $3.27
Also $3.27 + $0.07 + $0.80 = $4.14
You have $4.14 that you spent. The cashier should give you back $5.86.
So yes, you gave the cashier enough money and you got back money too.
Please mark me brainless.
