Answer:
14
Step-by-step explanation:
If each cupcake needs 1/2 cup of sugar, you need to divide the total cups of sugar by 1/2.
7 1/3 ÷ 1/2= 14.6
You cant have .6 of a cupcake, therefore she can make 14 cupcakes.
Andrew makes $10 per hour babysitting and $8 per hour working at the grocery store. He will need to make atleast $650 to buy a new computer. Are the variables defined correctly? (True or False) x = Hours babysitting y = Hours working at grocery store
Answer:
True
Step-by-step explanation:
Since babysitting and working at the grocery store are two different things, you would need two different variables.
So x and y would be the correct representation.

f=4x-3)²-(2x+4)²
a) factorise l'espression:
b)déduis en les solutions de l'equation: 4x-3)²-(2x+4)²=0
Answer:
A)(6x+1)(2x-7)
B)x={-1/6,7/2}
Step-by-step explanation:
A) (4x-3)²-(2x+4)²
(4x-3+2x+4)(4x-3-2x-4) (as a²-b²= (a+b)(a-b) )
(6x+1)(2x-7) (ans)
B) (4x-3)²-(2x+4)²=0
=>(6x+1)(2x-7)=0 (as we have gotten from a that (4x-3)²-(2x+4)² is equal to (6x+1)(2x-7) )
=>6x+1=0
=>2x-7=0
=>6x=-1
Therefore
x=-1/6
=>2x-7=0
=>2x=7
Therefore
x=7/2

Simplify the expression below using laws of exponents.
Answer: 36/[tex]K^{2}[/tex]
Step-by-step explanation:
The k on top will cancel the k to the second power.
So the only number in the numerator is 1.
Then the 1 qill go away because you cant divide anything by 1.
The expoenet -2 that was at the top near K will become positive.
Then distribute

Explain when it is appropriate to use a benchmark percent in solving a problem.
Answer:
The most common benchmark percents are 0%, 10%, 25%, 50%, 75% and 100%.
These benchmark values are sometimes used when estimating a solution involving percentages.
Real-World Example
If an item costs $36.00 and there is a 7% sales tax, the benchmark of 10% can be used to mentally estimate the sales tax of the item.
10% of 36, done mentally, is 3.6.
Since 7% is a bit less than 10%, the sales tax will be a bit less than $3.60.Step-by-step explanation:

x2 - 2xy + y2 when x = 3 and y = 2
Answer:
1
Step-by-step explanation:
Substitute 3 for x and 2 for y:
3^2 - 2(3)(2) + 2^2
= 9 - 12 + 4
= 1
3^2−(2)(3)(2)+2^2
3^2−(2)(3)(2)+2^2
= 1
In the system of equations, b is a constant. If the system has infinitely many solutions, what is the value of b?
Answer:
The value of b is 9.5
Step-by-step explanation:
If a system of equations has infinitely many solutions, that means the two equations are equal
If the system of equations ax + by = c, dx + ey = f, then
a = d ⇒ coefficients of xb = e ⇒ coefficients of yc = f ⇒ numerical termsLet us use this fact to solve the question
∵ 3x - y = 19 ⇒ (1)
∵ 1.5x - 0.5 y = b ⇒ (2)
∵ This system of equations has infinitely many solutions
∴ The coefficients of x must be equal
∴ The coefficients of y must be equal
∴ The numerical terms must be equal
→ Multiply equation (2) by 2 to make the coefficients of x and y on it
equal the coefficients of x and y in equation (1)
∵ 2(1.5x) - 2(0.5y) = 2(b)
∴ 3x - y = 2b ⇒ (3)
→ By comparing equations (1) and (3), 19 must equal 2b
∵ 2b = 19
→ Divide both sides by 2
∴ b = 9.5
∴ The value of b is 9.5
Solve for X.

Answer:
a(n)= -4n-6
Step-by-step explanation:
If you plug the number of the sequence in as n in the equation (1=-10, 2=-14, etc.) and then plug the actual number (-10, -14, etc.) in as the a(n), for each of the equations, the only one that works with all four is the first one.

PLS GIVE THE ANSWER!!!!!! ALSO ITS NOT A NUMBER IS IT C OR A
Answer:
I am confused there no picture so go with your gut man
Step-by-step explanation:
can someone solve -15 = - 7a - 4 - 4a
and m - 4m = -6
and 8v - 3 + 3v = 8
STEP BY STEP PLEASE.
Answer:
A=1, m=2, v=1
Step-by-step explanation:
A.
[tex]-15=-7a-4-4a\\\\-15+4=-11a-4+4\\\\-11=-11a\\\\a=1[/tex]
B.
[tex]m-4m=-6\\\\\\-3m=-6\\\\\\3m=6\\\\m=2[/tex]
C.
[tex]8v-3+3v=8\\\\11v-3=8\\\\11v-3+3=8+3\\\\11v=11\\\\v=1[/tex]
For A, I first subtracted -4 from -7 as their variables are the same. I cannot subtract integers from variables. Then, I added 4 on both sides to move the integer on the left side. (This would also remove the -4 on the right side because -4+4=0) Then I divided -11 by both sides to get 1a or a.
For B, I subtracted -4 from 1 as their variables are the same. This time, since they are both negative numbers, I can make them both positive. So, just divide 3 by both sides as we want to get 1m.
For C, Add 3 to 8 as v is their variable. Then, I added 3 to both sides because we want to get the variable on one side. Divide by 11 and you will get v=1.

At the grocery store ,8 oranges cost $4 what is the cost for 9 oranges ?
Answer:
$4.50
Step-by-step explanation:
First step is to find the price per orange. You can do this by dividing total cost by oranges bought. See below.
[tex]4 \div 8 \\ = .50[/tex]
Now to find the amount of 9 oranges, you'd multiply price per orange by the specified amount needed (so 9)
[tex]9 \times .50 \\ = 4.50[/tex]

Liliana spends $4.00 on 2 boxes of popcorn and 2 drinks.Nadette spends $5.25 on 2 boxes of popcorn and 3 drinks.The prices of the popcorn and drinks can be determined by solving the system of equations.
2p+2d=4.00
2p+3d=5.25
what is the price of a box of popcorn? A drink?
P=
D=
Answer:
p=0.75$
d=1.25$
Step-by-step explanation:
2p+2d=4
So 2p=4-2d
2p+3d=5.25
4-2d+3d=5.25
d=5.25-4
d=1.25
2p+1.25*2=4
2p=4-2.5
2p=1.5
p=0.75
simplify
3x+6y+5y-2y
