If youre writing an exprssion all you need to do is make variables and multiply by the given number A, C, and S will be our variables.
2A + 3C + 1S = Total cost for andrews family 

4A + 2C = Total cost for Spencers family

Now, Does 2A + 3C + 1S = 4A + 2C

lets say A = 5 , C = 3 , and S = 2
2(5) + 3(3) + 1(2) = 4(5) + 2(3) 
10 + 9 + 2 = 20 + 6
21 = 26 

if this is your example then No, the spencers family spent more than the andrews family, youll have to do the math differently and may come up with a different answer if you were given values that you didn't give us, but this is how its done :) 

Hope this helps!

pochemuha

Answer:

Answer: Osvoldo did not meet his goal.

Step-by-step explanation:

Total carbohydrate ate by Osvoldo = 220 g

carbohydrate from grains = 55 g

Percentage of carbohydrate of grain is

\begin{gathered}=\dfrac{\text { carbohydrate taken from grains}}{\text {Total carbohydrate}} \times 100\\\\= \dfrac{55}{220} \times 100= 25 \%\end{gathered}

=

Total carbohydrate

carbohydrate taken from grains

×100

=

220

55

×100=25%

Goal of getting carbohydrate from grains = at least 30%

but he ate only 25% of carbohydrate

Hence, Osvoldo did not meet his goal as he ate less carbohydrate than his goal.

A 25-foot ladder is leaned against a wall. If the base of the ladder is 7 feet from the wall, how high up the wall will the ladd
GenaCL600 [577]

Answer:

24ft

Step-by-step explanation:

Pythagorean Theorem!!

a^2 + b^2 = c^2

------------------------

In this case, the ladder is c, and the base is b.

------------------------

Plug the numbers in the formula.

a^2 + 7^2 = 25^2

------------------------

Solve.

a^2 + 49 = 625

a^2 -49 = 625 - 49

a^2 = 576

\sqrt{a^2} = \sqrt{576}

a = 24

The function f(x) is defined as follows:
Leno4ka [110]

Answer:

f(-3)=-8\\f(2)=4

Step-by-step explanation:

In order to find the values of a piecewise function, we first have to determine which piece we are using.

For f(-3), x=-3. This means that we need to use 3x+1 as -3\leq 0

f(-3)=3(-3)+1\\\\f(-3)=-9+1\\\\f(-3)=-8

For f(2), x=2. This means that we need to use f(x)=4 as x is equal to 2.

f(x)=4
