Writing algebraic expressions need help with homework

Mathematics
1 answer:
mina [271]3 years ago
6 0

Answer:

a. 2x-2

b. Samuel's cousin's age

Step-by-step explanation:

To write this expression, first figure out what your variable stands for. In this case, we want x to represent Samuel's cousin's age, since this is an unknown value that will help us determine Samuel's age. Next, we can create an expression. 2x-2 tells us that Samuel is two years younger (represented by the -2 part of the expression) than twice his cousin's age (represented by the 2x part of the expression).

Answer:

x=3

Step-by-step explanation:

Given: 15=7x-6

To solve this equation, we need to isolate x on one side of the equation algebraically. I see that we have like terms, but they are on opposite sides of the equal sign. Let's add 6 to both sides.

21=7x

To isolate x, divide both sides by 7.

x=3

Osvoldo has a goal of getting at least 30% of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of
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.

Hello!

Each minute on a clock or watch is 6°, as you divide 360° by 60 minutes. As you can see, 32 minutes elapsed during the class. Therefore we just multiply.

32(6)=192

Therefore, our answer is B) 192.

I hope this helps!
