Answer 2
Answer: Answer: x = 6

Explanation:
3* 5+ 6 = 21
So it is not greater than 21, it’s the same as 21
But,
3* 6= 18 + 6 = 24
And
24>21

Jan's pencil is 8.5 cm long. Ted's pencil is longer. type a demical that could represent the length of ted's pencil

Answers

Answer: Ted's pencil could be 8.6 cm.

Step-by- Step explanation:

Since we have given that

Length of Jan's pencil= 8.5 cm

According to the question, we know that Ted's pencil is longer.

So, it must be larger in value than 8.5 cm .

So, it can be any decimal number greater than 8.5 cm

Hence, Ted's pencil could be 8.6 cm.
If Jan's pencil is 8.5 cm long, and Ted's is longer, anything larger than 8.5 should work.

The surface area for a rectangular prism with a square base is given by the expression. 2s2+4sh, where side s is side length of the

Answers

Answer: the answer is 40 units squared

Step-by-step explanation:

the SA with a rectangular and square base is 2*s²+4*s*h

2*s²= the surface area

4*s*h= sideways (lateral)

s= 2 and h=4

so then plug it into "2*s²+4*s*h" and you get 2*2²+4*2*4

2*2²+4*2*4

3/5 =2/3t what is t PLZ HELP

Answers

3/5 = (2/3)t
cross multiply
9/10 = t
2/3t = 3/5

Divide (inverse operation)

2/3t/2/3 = 3/5 divided by 2/3

3/5 * 3/2 = 9/10

t = 9/10

Answer: t = 9/10

If Tim ran four and one half miles on Saturday and he ran seven and one third miles on Sunday. How many total miles did Tim run

Answers

Saturday 4 1/2

Sunday 7 1/3

First you would have to find common denominator

4 1/2 + 7 1/3

4  3/6  + 7  2/6  = 11 5/6

So, Tim ran a total of 11 5/6 miles on both days.

Hope that helps you. :-)
Saturday: ran 4 1/2 miles
Sunday: ran 7 1/3 miles
4 1/2 + 7 1/3
4 3/6 + 7 2/6= 11 5/6
Tim ran 11 5/6 miles total

What is 2/4 + 4/5 - 7/10 ? Please help

Answers

Make sure they have all common denominators
(2)/(4) + (4)/(5) - (7)/(10)

(2)/(4) * (5)/(5) = (10)/(20)

(4)/(5) * (4)/(4) = (16)/(20)

(7)/(10) * (2)/(2) = (14)/(20)

(10)/(20) + (16)/(20) - (14)/(20)

Add (10)/(20) + (16)/(20) = (26)/(20)
(26)/(20) - (14)/(20) = (12)/(20)

To simplify, you must find the largest common factor which 4
In (12)/(20)
12÷4=3 and 20÷4=5

The answer is (3)/(5)
