Answer: -67
Step-by-step explanation:
Maggie's brother is 7 years younger than four times her age. The sum of their ages is 48. How old is Maggie? Maggie is years old.
Answer:
11 years old
Step-by-step explanation:
Maggie's age is x
Maggie's brother = 4x - 7
The sum is 48
x + 4x - 7 = 48
5x - 7 = 48
5x = 55
x = 11

add please -35.25+(8.5)
Answer:
Hello the answer is -23.75
plus +minus=Minus so we will minus it
Answer:
-26.75
Step-by-step explanation:
So what I did is I took away the minus sign and put it in front of 8.5 instead so the equation became: 35.25-8.5. Then, I subtracted which gave me 26.75 and then I added the minus sign back in which gave me -26.75.

Answer:
y=x*6
Step-by-step explanation:
it is y=x*6 because the y axis is every x's six times.
Answer:
y=6x
Step-by-step explanation:
Frist, you are going to use y=mx+b
M= the slope of the line.
B= the y-intercept( where the line crosses the y-axis).
Slope= [tex]\frac{Rise}{Run} =\frac{30}{5}[/tex] the you simplify it to [tex]\frac{6}{1}[/tex]= 6
Now, you plug in your equation for m.
y=6x+b
Y-Intercept= where the line crosses the y-axis.
In this case it is at 0. Now plug it in.
y=6x+0
Whenever your "b" is 0 you don't need to add +0 in your equation.

Simplify the expression: (3 -- 10)2 + 4 : 2
Answer:
-12 Use PEMDAS
Step-by-step explanation:
Do the operation in the parenthesis first to get (-7)2 + 4:2. Multiply -7 by 2 to get -14 +4:2. Divide 4 by 2 to get -14 + 2. Add -14 and 2 to get -12.
Jemila has $10, $5, and $1 bills in her piggy bank. Their total value is $63. If she has two more $5 bills than $10 bills, and three more $1 bills than $5 bills, how many of each bill does Jemila have?
Answer:
She has 3 $10 bills, 5 $5 bills and 8 $1
3 times 10= $30
5 times 5 = $25
8 times 1 = $8
$30 + $25 + $8 = $63
A system of equations is a group of equations that can be solved simultaneously. Here we can find one that allows us to solve the given question.
We will see that: Jemila has 8 $1 bills, 5 $5 bills, and 3 $10 bills.
First, let's define the variables:
x = number of $1 bills in the piggy bank.y = number of $5 bills in the piggy bank.z = number of $10 bills in the piggy bank.Then the total amount of money in the piggy bank is:
$1*x + $5*y + $10*z
And we know that the total value is $63, then one equation is:
$1*x + $5*y + $10*z = $63
We also know that she has two more $5 bills than $10 bills, then:
y = z + 2
We also know that she has three more $1 bills than $5 bills, then:
x = y + 3
So our system of equations is:
$1*x + $5*y + $10*z = $63
y = z + 2
x = y + 3
To solve this, we need to isolate one of the variables in one of the equations. We can see that some variables are already isolated, like on the second or third equations.
For example, we can replace the second equation into the first and third ones:
$1*x + $5*y + $10*z = $63
x = y + 3
$1*x + $5*(z + 2) + $10*z = $63
x = (z + 2) + 3
Now we can simplify these to get:
$1*x + $15*z + $10 = $63
x = z + 5
Now we can replace the second equation on the first one:
$1*x + $15*z + $10 = $63
$1*(z + 5) + $15*z + $10 = $63
Finally, we can solve this for z.
$16*z + $5 + $10 = $63
$16*z = $63 - $15
$16*z = $48
z = $48/$16 = 3
z = 3
Now that we know the value of z, we can use it in the equations:
x = z + 5 = 3 + 5 = 8
y = z + 2 = 3 + 2 =5
Then the solution is:
x = 8y = 5z = 3Then Jemila has 8 $1 bills, 5 $5 bills, and 3 $10 bills.

I think its $120
Step-by-step explanation:
there are 20 players each having 2 slices. Meaning that they'll need 40 pizzas. each box has 8 slices so theyll need 5 boxes for 40 pizzas. each box costs $24 so that will be $24 x 5 =$120
Check all equations that are equivalent.
EXPLAIN please
Step-by-step explanation:
A = ½ h (b₁ + b₂)
Multiply both sides by 2:
2A = h (b₁ + b₂)
Distribute the h:
2A = h b₁ + h b₂
So the second option is not correct.
Instead of distributing, divide by h:
2A/h = b₁ + b₂
Subtract b₂ from both sides:
b₁ = 2A/h − b₂
Third option is correct.
Next, use common denominator to combine.
b₁ = 2A/h − h b₂/h
b₁ = (2A − h b₂) / h
Factor out 2.
b₁ = 2 (A − ½ h b₂) / h
Fourth option is correct.

Point V is on line segment \overline{UW}
UW
. Given UV=6,UV=6, UW=5x,UW=5x, and VW=4x-1,VW=4x−1, determine the numerical length of \overline{VW}.
VW
.
Answer: VW = 19
Step-by-step explanation: The segment UW has a point V between them, so:
UV + VW = UW
6 + 4x - 1 = 5x
4x + 5 = 5x
x = 5
The numerical length is
VW = 4x - 1
VW = 4(5) - 1
VW = 19
The measure, numerically, of VW is 19
