Read below

Step-by-step explanation:

<em>x is always the smaller number</em>

<em>y is always the larger number</em>

<u>underlined</u> means it's the question

bolded means it's the answer

<em>1. </em>

<u>One number is 6 times as large as another. Their sum is 42. Find the numbers.</u>

The numbers need to fit the criteria:

6x=y
x+y=42

A. 6+36=42 (correct)

B. 7+42=49 (incorrect)

C. 7+35=42 (incorrect because it doesn't follow the 1st rule)

D. 6+42=48 (incorrect)

Only A. 6, 36 fits the criteria.

<em>2. </em>

<u>One number is 3 less than another. Four times the smaller is 4 more than 3 times the larger. Find the numbers.</u>

The numbers need to fit the criteria:

x+3=y
4x-4=3y

A.

4+3=7

12-6≠21 (incorrect)

B.

7+3=10

28-3≠30 (incorrect)

C.

Only C. 13, 16 fits the criteria.

<em>3. </em>

<u>One number is 4 less than another. Five times the smaller is 3 less than 4 times the larger. Find the numbers.</u>

The numbers need to fit the criteria:

x+4=y
5x+3=4y

A.

13+4=17

65+3=68 (correct)

B.

If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 212 feet long and 112 feet wide

skad [1K]

Answer:

You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide

Step-by-step explanation:

<u><em>The complete question is</em></u>

Elena needs to find a table that will fit three cube-shaped cases, each containing a frog.If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 2 1/2 feet long and 1 1/2 feet wide?Explain

step 1

Find the length side of the cube-shaped case

we know that

The volume of the cube is equal to

$V=b^3$

where

b is the length side of the cube

we have

$V=1,000\ in^3$

substitute

$1,000=b^3$

solve for b

$b=10\ in$

step 2

Convert feet to inches

$1\ ft=12\ in$

we have

$2\frac{1}{2}\ ft=2.5 (12)=30\ in$

$1\frac{1}{2}\ ft=1.5 (12)=18\ in$

step 3

Compare the dimensions of the table with the dimensions of the cube-shaped case

30 > 10

The length of the table is greater than the length side of the cube

18> 10

The width of the table is greater than the length side of the cube

therefore

You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide

Thankssssssss smmmmmmm

Answer:

46

Step-by-step explanation:

The length of base CD is twice the length of midsegment FG, so you can write the equation ...

CD = 2×FG

-3x +52 = 2(13 +5x)

52 = 26 +13x . . . . . . . . add 3x, simplify

26 = 13x . . . . . . . . . subtract 26

2 = x . . . . . . . . . . divide by 13

Then the measure of CD is ...

CD = -3x +52 = -3(2) +52 = -6 +52

CD = 46
