Expressions do not have an equal sign (although they can have operators such as plus or minus).

2x+1 is an expression.

2x+1=1 is an equation since it has an equal sign.

Calculus! PLEASE PLEASE PLEASE I NEED HELP!!?
-Dominant- [34]
We do
how much added-howmuch subtracted

\int\limits^5_0 {F(t)} \, dt - \int\limits^5_0 {E(t)} \, dt
or
\int\limits^5_0 {F(t)-E(t)} \, dt
so
first simlify F(t)-E(t) (if you want, not necicary if use calculator)
(t+7-ln(t+4))/(t+2)=F(t)-E(t)

evaluate
\int\limits^5_0  \frac{t+7-ln(t+4)}{t+2} } \, dt≈9.05584

A total of 1,650 boxes of Girl Scout cookies were sold last week. Each large box cost $3.50 and each small box cost $2.00. The G
s344n2d4d5 [400]

Answer:

900 large boxes were sold, and 750 small boxes.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of large boxes of cookies sold.

y is the number of small boxes of cookies sold.

A total of 1,650 boxes of Girl Scout cookies were sold last week.

This means that

x + y = 1650

So

x = 1650 - y

Each large box cost $3.50 and each small box cost $2.00. The Girl Scout group earned $4,650.

This means that

3.5x + 2y = 4650

Since x = 1650 - y

3.5(1650 - y) + 2y = 4650

5775 - 3.5y + 2y = 4650

1.5y = 1125

y = \frac{1125}{1.5}

y = 750

x = 1650 - y = 1650 - 750 = 900

900 large boxes were sold, and 750 small boxes.
