Answer:
The answer to 7 × 9 will be equal to 63
Step-by-step explanation:
The <em>commutative property of multiplication</em> says you get the same answer from 9 × 7 as from 7 × 9.
Answer:
false I think
Step-by-step explanation:
because a term in an algebraic expression that does not contain any variables and therefore is constant.
Answer:
x = 4
Step-by-step explanation:
Set the exponents equal to each other
2x + 1 = x + 5
Subtract x from both sides
x + 1 = 5
Subtract one from both sides
x = 4
So, the value of x is equal to 4.
Let's say x = full price tickets
Let's say y = student tickets
We can write two equations:
From "585 tickets were sold" we can make the equation:
x + y = 585
And from "Full-price ticket is $2.50 and student ticket is $1.75 and total receipts is $1,217.25"...we can make the equation:
2.50x + 1.75y = 1,217.25
So now we can use substitution to find our answer...since we only have to find how many student tickets...we will solve the first equation for x so we can plug that into the 2nd equation to solve for y.
x + y = 585
x + y - y = 585 - y
x = 585 - y
Now we plug that into our 2nd equation: 2.50 (585 - y) + 1.75y = 1217.25
Distribute your 2.50
1462.5 - 2.50y + 1.75y = 1217.25
Add the y's: 1462.5 - 0.75y = 1217.25
Subtract 1462.5 from both sides:
1462.5 - 0.75y - 1462.5= 1217.25 - 1462.5
-0.75y = -245.25
Divide both sides by -0.75:
y = -245.25/-0.75
y = 327
There were 327 student tickets :)
Answer: (the function is 8^X, not 8X.)
Step-by-step explanation:
X = 1 8^X = 8
X = 2 8^X = 64
X = 3 8^X = 512
X = 4 8^X = 4096
