How can we use a number line to model and find the sum of -8 + 5?

Answers

Answer 1

Answer:

-3

Step-by-step explanation:

Because -8 plus 5 equals -3 since the number for 8 is in negative the number added threw 5 goes up to higher 0

Answer 2
-3 because (-8)+5 adds on so it would take 5 away making it -4

Mercedes receives a $25 gift card for downloading music and wants to determine how many songs she can purchase. Each downloaded song costs $1.29. Write and solve an inequality to determine m, the number of songs Mercedes can purchase. What is the approximate solution to the inequality? Round to the nearest whole number.
m less-than-or-equal-to 19
m greater-than-or-equal-to 19
m less-than-or-equal-to 32
m greater-than-or-equal-to 32

Answers

Answer:

A

m less than or equal to 19

She can  buy at most 19

Step-by-step explanation:

25 divided by 1.29 is 19.379844... but you can't buy fractions of a music song.

So the closest to the maximum would be 19.

The letters of the alphabet are each assigned a random integer value, and H=10. The value of a word comes from the sum of its letters' values. If MATH is 35 points, TEAM is 42 points and MEET is 38 points, what is the value of A?

Answers

Answer:

M  +  A     +   T    +   10  =   35   →    M  +   A    +   T    =   25     (1)

T   + E    +   A      +   M  =    42      (2)

M  + E     +  E     +    T  =    38       (3)

If  we look at  (1)  and (2)   we  note  that

T  +  E   +  A    +  M  =  42

So

(M  +  A   +  T)    +   E   = 42

So

25   + E   = 42

E    = 17

Looking at (3)   we  have  that

M + E  + E  +  T    =  38

M  +  2(17)  + T =  38

M + T   =  38  - 2(17)

M + T  =  38  - 34

M + T    =  4

So...looking back at  (1)

M + A  +  T    =25

M + T  + A  =  25

4  + A    =25

A  = 21 is the answer

d. They both have a strong assoication, but Graph 1 has a negative correlation while Graph 2 has a positive correlation​

Answers

the answer is b (they both have a positive correlation)

The comparison between the two graphs is that: B. they both have a positive correlation, but Graph 2 has a stronger association.

What is a positive correlation?

A positive correlation refers to a terminology that describes a scenario in which two or more variables move in the same direction and are in direct proportion.

This ultimately implies that, a positive correlation exists in a graph when its variables have a linear relationship or are in direct proportion.

Based on the graphs attached in the image below, we can deduce that the two graphs both have a positive correlation, but Graph 2 has a stronger association.

The measure of angles in a triangle are in a ratio of 2:3:4. What are the measures of the angles?

Answers

Answer:

The angle measures are 40°, 60°, and 80°.

Step-by-step explanation:

When we are given this problem, we need to know that

There are three angles in a triangle.These angles add up to equal 180°.

With this ratio, these angles must add up to equal 180°. Therefore, we can set up an equation and add an x-variable to each of the numbers. We then set this equal to 180.

[tex]\text{2x + 3x + 4x = 180}\\\\\text{9x = 180}\\\\\text{x = 20}[/tex]

Now, we need to find the measures of the angles. The angles are the parts of the ratio multiplied by the value of x.

[tex]\text{2(20) = 40}\\\\\text{3(20) = 60}\\\\\text{4(20) = 80}[/tex]

So, our three angles measures should be 40°, 60°, and 80°. We can check this by adding up these three values and seeing if the sum equals 180°.

[tex]\text{40 + 60 + 80 = 180}\\\\\text{100 + 80 = 180}\\\\\text{180 = 180}[/tex]

Because this is true, our angle measures are 40°, 60°, and 80°.
