Answers

The top and bottom are each triangle with base 6 in and height 3 in. So, 6 * 3 / 2 is 9 in^2 for each the top and bottom.

There are 2 rectangles with sides 5 in and 12 in, and 1 rectangle with sides 6 in and 12 in. The areas of the first rectangles are 60 in^2, and the second rectangle is 72 in^2.

Add up the 5 shapes, and you'll have:

9 + 9 + 60 + 60 + 72 = 210 in^2

show how to solve the problem 378 ×6 using place value with regrouping. explain how you knew when to regroup

Answers

You should regroup when the product of the two numbers are greatre than nine so 378*6 6*8 is 48 so you would the 8 and regroup the 4 and do the same thing for the rest of the numbers if the product is greater than nine. Your answer will be 2268.

Expand 378 as (300+70+8) then multiply it 6. It will be (300 x 6)+(70 x 6)+(8 x 6)=

1800+420+48=2268

2. Tom's brother saw an advertisement for a special at Muscle Fitness. Muscle Fitness is offering $20 off the one-time regular registration fee of $80. Membership is $15 per month with a mandatory additional $5 charge per month for equipment maintenance. Tom's brother tells Tom that he feels it is a better deal than Platinum Gym. (a) Write an expression to represent the membership cost of Muscle Fitness for x months. (b) Is Tom's brother right? Explain why or why not.

Answers

A) 80 - 20 = $60 for registration and 15 + 5 = $20 every month. 20x + 60= cost of Muscle Fitness

B) Tom's brother is wrong. They cost the same amount. Platinum Gym cost's $20 a month and $60 for registration as well as Muscle Fitness. There is no better deal or worse deal. They cost the same amount.

Simplify: Negative four and one-fifth minus negative thirteen and one-tenth

Answers

-4 1÷5 - (- 13 1÷10)

first we should turn these into improper fractions by multiplying the whole number by the denominator then add the numerator.

4 × 5 = 20 + 1 = 21
13 × 10 = 130 + 1 = 131

(-21/5) - (-131/10)

To subtract fractions we want to find a common denominator so we can multiply the numerator and denominator of (-21/5) by 2 to get (-42/10)

(-42/10) - (-131/10)

Since we are subtracting a negative, that becomes a positive

(-42/10) + 131/10

131 - 42 = 89

89/10

Now we can change it back into a mixed fraction:

8 and nine-tenths or 8 9÷10
