Three times the sum of a number and 6 is less than 33

Answer:

-5°F

Step-by-step explanation:

As, in 2 hrs = - 10°F

For 1 hr = - 10°F/2 = - 5°F

So, answer = - 5°F

Answer:

Step-by-step explanation:

Now the slopes and the y-intercepts.

Answer:

put it on -1

Step-by-step explanation:

you turn the mixed number into an improper fraction and then you turn -11/6 to have a denominator of 3 so then it comes out to -1 1/2 over 3 then you multiply the 3 times 2 and the 1 1/2 times 2 and you get -3/3 and equals out to -1

D. 3/15

Step-by-step explanation:

3/15 x 15/3 = 1

You would have do multiply the fraction by 3/15

Step-by-step explanation:

15/3 × 3/15 = 45/45 which, when simplified, would equal 1

Answer:

[tex]\Large\boxed{\text{The amount of money changes by \$50 per week.}}[/tex]

[tex]\Large\boxed{s(t) = 70+50t}[/tex]

Step-by-step explanation:

We can create a function based on this scenario.

We know that you start with $70. This would be a constant. So, we already know that our function will contain +70.

If we earn $50 a week, we know that we can create an expression here to find how much we make based on how many weeks we spend, assuming t represents the amount of weeks we spent.

[tex]50t[/tex]

We can add this to our original constant of 70.

[tex]70+50t[/tex]

Since the output will be a function based on how many weeks we spend, we can make it equal to s(t).

[tex]s(t) = 70+50t[/tex]

The slope here is 50, meaning that every week we earn 50 dollars more.

This means the amount of money changes by 50$ per week.

Step-by-step explanation:

✍️MAD for Juniors:

✔️Write out the individual scores represented in the dot plot:

505, 505, 510, 515, 525, 530, 530, 540, 550, 550

✔️Find the mean of the data set = [tex] \frac{505 + 505 + 510 + 515 + 525 + 530 + 530 + 540 + 550 + 550}{10} = \frac{5,260}{10} = 526 [/tex]

✔️Find |data value - mean|:

|505 - 526| = 21

|505 - 526| = 21

|510 - 526| = 16

|515 - 526| = 11

|525 - 526| = 1

|530 - 526| = 4

|530 - 526| = 4

|540 - 526| = 14

|550 - 526| = 24

|550 - 526| = 24

✔️Find the sum of |data value - mean| and divide by 10:

[tex] \frac{21 + 21 + 16 + 11 + 1 + 4 + 4 + 14 + 24 + 24}{10} = \frac{140}{10} = 14 [/tex]

✔️Find the mean of the data set = sum of all values in the data set ÷ 10 = 554.5

✔️Find the M.A.D by dividing the sum of |data value - mean| by 10:

[tex] \frac{144}{10} = 14.4 [/tex]

-16/5

Step-by-step explanation:

calculating the gradient you use the formula change in y/change in X

subtract y coordinate -3-6=-5

subtract X coordinate -10-6 =-16

-16/5 = -16/5 or -3.2

Answer:

Step-by-step explanation:

Number of weeks is x

Answer:

[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]

Step-by-step explanation:

Let E represent Erin’s weight, and let M reprevent Miranda’s weight.

And let x represent the amount of week that passes.

Eric is currently 135 pounds. However, she is gaining 1/2 pounds per week x.

Hence, we can write the following equation:

[tex]D=135+\frac{1}{2}x[/tex]

Miranda currently weights 143 pounts. However, she is losing 1/4 pounds per week x.

Since she is losing weight, 1/4 is negative. Hence:

[tex]M=143-\frac{1}{4}x[/tex]

When the two girls weigh the same, D=M. Thus:

[tex]D=M[/tex]

Substitute them for their respective equations to acquire:

[tex]135+\frac{1}{2}x=143-\frac{1}{4}x[/tex]

Notes:

To solve, first eliminate the fractions by multiplying everything by 4. This yields:

[tex]540+2x=572-x[/tex]

Add x to both sides. Subtract 540 from both sides:

[tex]3x=32[/tex]

Divide both sides by 3:

[tex]x=32/3\approx10.67[/tex]

Hence, it will take about 11 weeks for the girls to weigh the same.

Answer:

i. 4∈C => False

ii. 5∈C => True

iii. A = B => False

iv. B=C => True

Step-by-step explanation:

Given sets are:

[tex]A = \{2,3,4\}\\B = \{2,5,6\}\\C = \{5,6,2\}\\D = \{6\}[/tex]

Lets look at the statements one by one.

i. 4∈C

This statement means that 4 is a member of set C. Looking at the members of set C, it can be concluded that the statement is wrong as C doesn't contain 4.

ii. 5∈C

This statement is true as 5 is a member of C.

iii. A=B

This statement states that set A is equal to set B. Two sets are said to be equal if there number of elements and members are same. Set A and Set B have different members so this statement is false.

iv. B=C

Set B and Set C have equal number of members and the members (5,6,2) are also same so the statement is true.

Hence,

i. 4∈C => False

ii. 5∈C => True

iii. A = B => False

iv. B=C => True

Answer:453rft

Step-by-step explanation:

Answer:

-1.6r + 1.8

Step-by-step explanation:

-1.6 (r+2) +5

^ the -1.6 can be distributed to the (r+2) because it's basically multiplying

that becomes --> -1.6r + -3.2 + 5

Now the -3.2 and 5 are like terms so they can be solved together

-> -3.2 + 5 = 1.8

Now, -1.6r and 1.8 are not like terms because 1.8 does not have an r attached to it so you cannot do nothing from there

your answer becomes = -1.6r + 1.8

Answer: 1.47

Step-by-step explanation:i did the quiz and got it right

Answer:

first question: Michelle worked for 7 hours

second question: Ken had $40 before buying the game

Step-by-step explanation:

4x + 65 = 93

4x = 28, x = 7

Michelle worked for 7 hours

Ken 1/2x + 12 = 32

1/2x = 20

x = 20. 20*2 = $40, ken has $40 before buying the game.

Answer:

8.4

Step-by-step explanation:

0.9c - 2.3d

given c = 17 and d = 3, substitute these into the expression:

0.9c - 2.3d

= 0.9(17) - 2.3(3)

= 15.3 - 6.9

= 8.4
