Which phrase represents this expression? 42−3×8

Mathematics
1 answer:
iVinArrow [24]2 years ago
3 0

Answer: C

Step-by-step explanation:

Let’s establish some key terms here:

Subtraction = <u>Difference</u>

Multiplication = <u>Product</u>

Division = <u>Quotient</u>

Addition = <u>Sum</u>

First, we know that there is subtraction and multiplication is the problem, so we will be using the words difference and product.

The only answer that uses both these words is answer C.

Either way, let’s check it.

Answer C is “the difference of 42 and the product of 3 and 8”. Let’s break it down.

We see the word “product“ here, talking about the 3 and the 8. In the original equation, the 3 and 8 were multiplied, so this does make sense.

We also see the word “difference”, talking about the 42 and the product (of 3 and 8). These were subtracted by each other in the original equation, so it makes sense.

Therefore, the answer is C: the difference of 42 and the product of 3 and 8.

Hope this helps! :)

What is the value of the variable -38 = 2b + 25 - (-7b)
ddd [48]
The variable in this equation is b, therefore we have to calculate the value of b.

-38=2b+25-(-7b)
-38=2b+25+7b
2b+7b=-38-25
9b=-63
b=-63/9
b=-7

Answer: the value of the variable is b=-7

We can check it out this answer:
-38=2b+25-(-7b)
-38=2(-7)+25-(-7(-7))
-38=-14+25-49
-38=-38

Hayden had 2 and 1/2 gallons of water in his watering can. The seed packet said to use 1/4 of a gallon for peppers and 5/8 of a
Flauer [41]

Answer:

7/8 of a gallon

Step-by-step explanation:

First find a common denominator for each of the values, in this case eighths. Next, add the total water used for the tomatoes and peppers (you'll get 7/8 gallons). Then, convert the 2 and a half gallons to eighths, getting 20/8 of a gallon. Next, subtract the 7/8 from the 20/8; getting 13/8. Since you need to find the amount of water used for the lettuce, subtract the last value from 3/4 gallons (or 6/8)
