What is (1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x), simplified?(1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x)

1.6x + 7.3 – 0.6x + 2 – 7.8 + 3.4x

1.6x – 0.6x + 3.4x + 7.3 + 2 – 7.8

Answers

Answer 1

Answer:

Answer:

$4.4x + 1.5$

Step-by-step explanation:

$(1.6x + 7.3) + (-0.6x + 2) - (7.8 -3.4x)$

To simplify this we use order of operation PEMDAS

WE start with removing the parenthesis and then we combine like terms

Multiply negative sign inside the third parenthesis

$1.6x + 7.3-0.6x + 2-7.8 +3.4x$

Now we combine like terms

$1.6x-0.6x+3.4x=4.4x$

$7.3+ 2-7.8=1.5$

so simplified expression is $4.4x + 1.5$

Answer 2

Answer: (1.6x + 7.3) + (–0.6x + 2) – (7.8 – 3.4x)
1.6x + 7.3 – 0.6x + 2 – 7.8 + 3.4x
1.6x – 0.6x + 3.4x + 7.3 + 2 – 7.8
4.4x + 1.5
thats all I guess

The junior class has 50 students. Twenty-five students take only French, 15 take only Latin, and 10 take both. If a student is chosen at random from the class, what is the probability that the student chosen takes either French only or Latin only? 1/2 4/5 1

Answers

The answer is going to be 4/5

The answer is 4/5 because the combined probability (French only is .5, and Latin only is .3) for French only and Latin only is .8, which is equal to 4/5.

Two sides of an acute triangle measure 5 inches and 8 inches. The longest side is unknown. What is the greatest possible whole-number length of the unknown side?

Answers

Answer:

Hence, the greatest possible whole-number length of the unknown side is:

9 inches

Step-by-step explanation:

A corollary to the Pythagorean Theorem states that:

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

$c^2<a^2+b^2$

Here we have:

Let a=5 inches.

b=8 inches.

Then,

$c^2<5^2+8^2\n\nc^2<25+64\n\nc^2<89\n\nc<9.434$

Hence, to the greatest whole possible whole number length of the unknown side is:

9 inches.

Answer:

the answer is 9

Step-by-step explanation:

Chad washes windows after school to make some extra money. He charges $5.50 to wash each window. If the customer provides the supplies, Chad deducts $3.25 from the total cost. One customer paid a total of $27.50 and did not provide supplies. Which equation could be used to find the number of windows, w, that Chad washed for this customer? 5.5w + 3.25 = 27.5 5.5w - 3.25 = 27.5 5.5w = 27.5 5.5 - 3.25w = 27.5

Answers

Answer:

$\$5.50w=\$27.50$

Step-by-step explanation:

We know that Chad charges $5.50 per window washed, and he deducts $3.25 from the total cost if the costumer provides the supplies. However, in this case, the costumer doesn't provide the supplies, so Chad will charge $5.50 per window.

This relation can be expressed as

$\$5.50w$

Where $w$ represents windows.

If he charges $27.50, the relation is

$\$5.50w=\$27.50$

Therefore, the right answer is the third choice $\$5.50w=\$27.50$

If you want to find the number of windows Chad washed, you just have to solve the expression

$\$5.50w=\$27.50\nw=(\$27.50)/(\$5.50)\n w=5$

Chad washed 5 windows.

3.25w=27.5 is the correct answer.
